8 Best OneSignal Alternatives (2026) for Multi-Channel Notifications

OneSignal is a customer engagement platform that started with push notifications and now sends email, SMS, in-app messages and Live Activities from one dashboard.

Teams evaluating or already running OneSignal tend to look elsewhere when notifications become part of the product: alerts users can scroll back through, preferences each customer controls, and messages to people inside their customers’ companies. They want every kind of message in one system, an orchestration engine that keeps a record of every send, and a platform engineering, product, growth and their agents can all change.

What OneSignal does

OneSignal is used mostly by small teams: about 65 percent of its G2 reviewers are small businesses. It started with mobile push and added web push, email, SMS and RCS, in-app messages and Live Activities, all sent from one dashboard or through a REST API.

Marketers build campaigns in Journeys, a visual builder with branching and cross-channel steps, and target them with segments and data tags. The number of active Journeys, segments and tags grows with the plan. Paid plans charge a platform fee plus usage: mobile push by monthly active user, web push by subscriber, email and SMS by send. OneSignal AI, an agent in the dashboard, and the OneSignal MCP server are on every plan.

Why teams look for a OneSignal alternative

01Users need notifications they can come back to. A product alert that disappears when the banner closes is lost. OneSignal's documentation says it does not store the history of messages sent to each user, and tells you to save a copy on your own server or device to build an activity feed. That is a database, an API and a UI your team runs alongside OneSignal.
02Transactional alerts need a workflow engine and a record of every send. Journeys are built for campaigns: 3 active on Free, 5 on Growth and 20 on Professional, with webhook steps on annual plans only. The message history API, which lists who received a message, needs Professional or Enterprise, works for seven days after a send, and records no received event for messages sent to fewer than 1,000 recipients. A password reset or a payment alert goes to one person.
03The billing unit counts users you never messaged. OneSignal bills mobile push per monthly active user, and its pricing FAQ counts any mobile subscription active in the last 30 days, whether it opted in to push or not. The count covers every app in the organization together, so an app with many active users and few notifications pays for all of them.
04The free plan now stops at 1,000 monthly active users. From 1 September 2026 for new accounts and 1 October 2026 for existing ones, mobile push and in-app messaging on Free cover organizations with up to 1,000 monthly active users; above that, those channels stop until you move to Growth at $19 a month plus usage. SuprSend's free plan counts 10,000 notifications a month across every channel, whatever the number of users, and its first paid plan is $100 a month for 50,000.
05Customers need to control what they receive. OneSignal's preferences are push categories set through the opt-in prompt. A B2B product usually needs opt-in and opt-out per category and per channel, a preference centre inside the app, and defaults an admin sets for their whole company.
06Engineers and agents want to change notifications from the repo. OneSignal's docs list no CLI, and each environment is a separate app. Its MCP server, in beta, manages users, subscriptions, segments and templates, sends messages and exports data; it does not build or edit a Journey. A change to a campaign means clicking through the dashboard in each app.
07Some products need WhatsApp, Slack or Microsoft Teams. OneSignal's pricing page lists mobile push, web push, email, SMS and RCS, in-app and Live Activities, and no WhatsApp, Slack or Microsoft Teams channel. B2B products and markets outside the US often need one of the three.

How we compared these tools

We read each tool’s documentation, API reference, pricing page and trust or security page, and its G2 reviews, in September 2026.

What we compared on: feature depth, use cases covered, billing model, developer experience, AI authoring, and ease of use for technical and non-technical team members.

Three different kinds of product get called “OneSignal alternatives,” and they solve different problems.

Layer 1: Delivery providers

Firebase Cloud Messaging, Apple Push Notification service, Amazon SNS, Twilio and Amazon SES move a single message to a device, phone or inbox. Everyone on this list pays or uses one of them, OneSignal included: it sends Android push through FCM. On their own they have no user profiles, templates, journeys or logs a product manager can read, so all of that lives in your code.

Layer 2: Unified notification platforms

SuprSend and Knock sit between your product and the delivery providers. You send an event, and the platform decides who gets which message, on which channel, when, in which language and under which preference. Both cover transactional, product and engagement messages, ship an in-app inbox, and can be run from outside the dashboard. In SuprSend, the SuprSend agent and any MCP client build and change workflows, templates and tenants, and the CLI pushes them from the repo. Knock runs agents from its dashboard, Slack and MCP clients, and has a CLI.

Layer 3: Customer engagement platforms

OneSignal belongs here with Pushwoosh and Airship, which also started with push, and with Braze, MoEngage and Customer.io, which run campaigns for consumer brands at large scale. They are strong at segments, journeys, A/B tests and campaign analytics from a dashboard. Their agents mostly read campaign data or help in the campaign canvas. Product notifications, an embeddable inbox and preferences your customers’ admins control are usually left to you.

1.SuprSend

Best for running transactional, product and engagement notifications from one platform, with an inbox and preferences inside your product

SuprSend's architecture: your API calls, SDKs, CDPs and data warehouses feed workflows, preferences, templates and observability, which send through email, SMS, WhatsApp, push, Slack and Microsoft Teams providers and the in-app inbox

What SuprSend is. SuprSend is a US company, founded in 2022, that runs every notification a product sends from one platform, from transactional alerts to engagement campaigns. Engineering, product and growth teams work in it alongside their agents.

A complete orchestration engine

In-app inboxReal-time bell and feed, read state synced across devices, tabs, toasts, per-tenant feeds, six client SDKs, embedded or headless. Every plan, Free included.

WorkflowsA workflow engine with branches, conditions, delays, throttling, data fetch and webhook steps, and sends in each user's timezone. One send step reaches the user's channels in your order. Built visually, through the CLI or by an agent, with version history and rollback. Builder on every plan; throttling, fetch, webhook and timezone from Essentials.

User preferencesOpt in or out per category and channel, in a preference centre you embed or one SuprSend serves. Business.

TemplatingEditors for every channel, variants by tenant, user or language, version history with rollback, translation files. Every plan; translation files on Business.

Batching and digestsCollect events over a window and send one message, at a time the user picks. Business.

Per-tenant setupsEach of your customers gets its own branding, templates, preferences and provider routing. Business add-on, Enterprise.

ObservabilityStep-by-step workflow logs and message logs with the provider's error; 30 days on Free, 90 on paid plans; warehouse sync on Business.

Retries and fallbackBring your own providers; if one does not confirm delivery, the next one sends. Essentials.

DeploymentSuprSend cloud with 99.9% uptime, or your own VPC, on-prem or bring your own cloud with vendor support. SOC 2 Type II, ISO 27001, GDPR, HIPAA and CPRA. Self-hosted and BYOC on Enterprise.

How your team operates it

In the dashboard

The SuprSend agent builds a workflow from a description, drafts the copy for each channel and traces why a send failed. Product and growth work here and in Slack.

In your own agent

Connect the MCP server to Claude, ChatGPT, Cursor or any MCP client and build and change workflows, templates and tenants, test and send, and read the delivery log and analytics from there.

In your IDE or codebase

The CLI pushes and pulls workflows, templates, schemas and translation files, promotes staging to production and generates TypeScript types, so a bulk change is one command reviewed in a pull request.

Pricing. Free up to 10,000 notifications a month. Essentials starts at $100 a month for 50,000, then $2 per 1,000. Business starts at $250 a month for 50,000, then $5 per 1,000. Enterprise is custom.

Verdict. Choose SuprSend when notifications are part of your product and engineering, product, growth and their agents all change them; choose OneSignal when consumer push and in-app campaigns are the whole job and a marketer runs them. For the head-to-head, see how SuprSend differs from OneSignal.

2.Pushwoosh

Best for push and in-app campaigns to consumer apps, priced per person actually messaged

Pushwoosh's homepage: one platform for the complete user journey, from app install to repeat purchase

Where it goes deep. Pushwoosh started with push and still leads with it: iOS standard, silent, critical, VoIP and Live Activities pushes; Android through FCM, Huawei, Baidu and Amazon Fire; and web push on the major browsers. Its Customer Journey Builder runs push, in-app, email, SMS and WhatsApp in one flow, with wallet passes alongside. A monthly active user is a person you sent a message to that month, counted once by user ID across mobile and web push. The ManyMoney MCP server lets an agent send on push, email, SMS, WhatsApp, Telegram, LINE and Kakao, with a second endpoint for planning campaigns and managing segments. Pushwoosh lists ISO 27001:2022, a SOC 2 Type 2 report, HIPAA and GDPR, and runs migrations from OneSignal for customers.

Where it stops. Pushwoosh is a marketing platform for consumer apps, and its channel list has no Slack or Microsoft Teams. On G2, reporting is the most-cited drawback, from 50 reviews in total.

Pick it if your engagement runs on push and in-app messages, marketers run the campaigns, and you want to pay for the people you message.

Verdict. The closest like-for-like replacement for OneSignal. Choose it to keep the same way of working on a different count of who you pay for.

3.FCM + APNs, built in-house

Best for teams with engineers who want full control of push and no platform bill

Where it goes deep. Firebase Cloud Messaging sends mobile push, web push and in-app messages free at any volume, and Apple Push Notification service delivers to iOS; OneSignal itself sends Android push through FCM. You own everything above the transport: token storage, topic subscriptions, templates, scheduling and logs. The Firebase console composes push campaigns with A/B tests through Google Analytics, and the Firebase MCP server can send a message.

Where it stops. There is no user object, template, preference or workflow logic; all of it is your code. You store and clean registrations yourself, and Android registrations expire after 270 days. Email, SMS and an inbox are separate builds.

Pick it if push is your only channel, your needs are simple, and an engineer owns it long term.

Verdict. Free in fees and expensive in engineering time. Choose it when push is all you send and you would build the logic anyway.

4.Knock

Best for B2B software teams that want cross-channel workflows, an inbox and in-product guides from one cloud platform

Knock's homepage, with its agent building an onboarding workflow: a trigger, welcome email, 24-hour delay, agent step and a branch for managers and ICs

Where it goes deep. Knock runs workflows across email, SMS, push, chat, WhatsApp and an in-app feed, with batching, an object model for non-user recipients and Guides for in-product banners and modals. Agents run from the Knock dashboard, Slack and MCP clients, workflows can include agent steps, and a CLI lets engineers work from their editor. Client SDKs cover React, JavaScript, Angular, React Native, Expo, iOS, Android and Flutter.

Where it stops. Knock is cloud only. Per-customer branding and preferences, translations, custom roles, SAML, SCIM and a HIPAA BAA sit on Enterprise.

Pick it if your product sends notifications into Slack as well as email and push, and everything will run in Knock’s cloud.

Verdict. A strong unified platform for B2B products that live in Slack. Choose it when Enterprise gating of per-customer features does not affect your plan.

5.Airship

Best for large consumer brands that want push, an app inbox and native in-app screens changed without an app release

Where it goes deep. Airship started as a push provider (it was Urban Airship) and now calls itself a mobile app experience platform. Message Center gives each user a lasting app inbox, Preference Center lets users choose topics across push, SMS and email, and Scenes build native in-app screens marketers change without shipping a new app version. Feature flags and holdout experiments sit in the same dashboard. Its MCP server is a developer tool: it queries channel data, tests push flows and helps migrate SDKs.

Where it stops. Airship sells quoted annual contracts and publishes no prices. G2 reviewers score its setup 7.0, the lowest on this list.

Pick it if you run a large consumer app, need an inbox and in-app screens marketers own, and have the budget for an enterprise contract.

Verdict. The enterprise answer for apps where push is only the start. Choose it when native in-app experiences matter more than a fast, self-serve start.

6.MoEngage

Best for consumer lifecycle teams that want analytics and journeys in one platform

MoEngage's homepage: an agentic customer engagement platform, with agent cards for in-app templates and per-user decisioning

Where it goes deep. MoEngage joins product analytics (funnels, cohorts and retention) to segmentation and journeys across mobile push, web push, email, SMS, in-app, on-site messages and webhooks. Its Merlin AI agents generate in-app templates from a description, draft multi-stage journeys for a marketer to review and answer questions on campaign performance. The MoEngage MCP server gives an outside agent nine read-only tools for campaign search, performance, content and delivery diagnostics.

Where it stops. The MCP server is read-only, so an outside agent can report on campaigns and cannot build or change one. Prices come in a quote.

Pick it if your lifecycle team wants analytics and journeys in the same tool and works mostly from the dashboard.

Verdict. Suits consumer brands that want the analysis and the campaign in one place. Choose it for journey depth on a quoted contract.

7.Braze

Best for mid-market and enterprise lifecycle teams running deep journeys on many channels

Where it goes deep. Braze began as Appboy, a mobile push company, in 2011. Canvas adds experiment paths, decision splits, agent steps and version history to journeys, and it sends on WhatsApp, LINE and KakaoTalk as well as email from your own IPs. Content Cards and Banners give an in-app surface, and SQL Segment Extensions build segments on warehouse data. BrazeAI Operator works in the dashboard; the Braze MCP server reads analytics and creates templates and content blocks, with no user-level data.

Where it stops. Braze counts data points on profile updates, events and sessions, puts its own average time to value at six weeks, and has no CLI.

Pick it if a dedicated lifecycle team runs journeys on several channels and markets and needs experiments and warehouse segments.

Verdict. The deep end of customer engagement. Choose it when journey sophistication justifies a contract and a longer rollout.

8.Customer.io

Best for marketing campaigns triggered by product events and data

Customer.io's dashboard: a campaign goal report with conversions over time, attribution by message, and the agent panel

Where it goes deep. Customer.io started with email; push, SMS and in-app messages sit alongside it in the same campaigns. Campaigns trigger on events and on objects such as accounts, so a marketer can message every member of a company when its plan changes. An in-product agent drafts messages, and the Customer.io MCP server and CLI act under the signed-in user’s role, holding writes for approval where the client supports it.

Where it stops. There is no free plan, and billing counts profiles, both people and objects, so a product with many users and few messages pays for every profile.

Pick it if your marketers already work from product events and want email-first campaigns with push and in-app added.

Verdict. The event-driven marketing choice for software companies. Choose it when marketing is the job and product notifications sit elsewhere.

When you should stay on OneSignal

Your product is a consumer app, and push and in-app campaigns are most of what you send.
You have fewer than 1,000 monthly active users across all your apps.
A marketer runs messaging on their own, and engineering rarely needs to change it.
You have built on Live Activities and want them priced in with mobile push.
No customer asks for an inbox, preferences or WhatsApp, Slack or Microsoft Teams inside your product.

Teams that grow past campaigns on OneSignal end up writing code around it: a database and UI to keep each user’s message history, a preference store for categories beyond push, and scripts that copy templates and segments between the apps they use as environments. That code is a hidden cost: your team builds it, maintains it, and pays for it in engineering time on top of OneSignal’s price. What drives a switch is that code growing as notifications move into the product.

How to migrate off OneSignal

01Record baselines. Export delivery, open and click rates by channel and by message type for the last 90 days, so you can tell whether the new platform performs the same.
02Rebuild workflows. Map each Journey and API-triggered send to a workflow. On SuprSend, build them once and push them between environments with the CLI.
03Move tokens and subscribers. Export users, external IDs and push tokens. APNs and FCM tokens belong to your app, so imported devices keep working once the new SDK registers them.
04Carry consent state. Move opt-outs, unsubscribes and push category choices with each user, and import email and SMS suppression lists before the first send.
05Rebuild the inbox. If you built an activity feed on your own server, replace it with the new platform's inbox and backfill recent messages so users see their history.
06Dual-send. Run both systems on a small share of traffic, compare delivery against your baselines, then move one message type at a time.
07Keep the old system for 30 days. Leave OneSignal running until every scheduled message and Journey has moved and the numbers match.

Conclusion

OneSignal gets push, in-app, email and SMS campaigns live quickly for consumer apps, with published prices, strong documentation and an agent and MCP server on every plan. It is built around marketing campaigns to app users.

Move when notifications become part of your product. At that point you need every kind of message in one system, a complete orchestration engine with an inbox, preferences and a record of every send, and a platform your engineers, product and growth teams and their agents can all operate. SuprSend’s free plan covers 10,000 notifications a month to start.

FAQ

Is OneSignal free?

OneSignal's Free plan covers mobile push, in-app messages and Live Activities for organizations with up to 1,000 monthly active users, 10,000 emails a month and web push to up to 10,000 subscribers per send. The 1,000-user limit applies from 1 September 2026 for new accounts and 1 October 2026 for existing ones. Above it, Growth costs $19 a month plus $0.012 per mobile monthly active user.

What is the cheapest OneSignal alternative?

It depends on the unit, because these tools count different things. Free plans first: SuprSend includes 10,000 notifications a month, Knock 10,000 messages, Pushwoosh 1,000 monthly active users, and FCM is free at any volume. At 50,000 notifications a month, SuprSend Essentials is $100, then $2 per 1,000 (Business $250, then $5 per 1,000), and Knock Starter is $250. Pushwoosh and OneSignal count users: 50,000 users cost about $343 a month on Pushwoosh Push only and about $619 on OneSignal Growth. Customer.io counts profiles, from $100 for 5,000.

Which OneSignal alternatives include an in-app inbox?

SuprSend and Knock ship a real-time in-app feed with SDKs for web and mobile. Airship has Message Center, and Braze has Content Cards. OneSignal's documentation says it does not store the history of messages sent to each user, so an inbox on OneSignal is something you build and run yourself.

Which OneSignal alternatives have an MCP server or agent authoring?

SuprSend's agent builds workflows, drafts copy and traces failed sends, and its MCP server builds and changes workflows, templates and tenants, tests and sends, and reads logs and analytics. Knock runs agents from its dashboard, Slack and MCP clients and has a CLI. Pushwoosh's MCP server sends messages and plans campaigns. MoEngage's is read-only. Airship's is a developer tool for testing push and migrating SDKs. OneSignal's, in beta, manages users, segments and templates and sends messages; it does not build Journeys. See what SuprSend agents can do.

Can one platform handle transactional and marketing notifications?

Yes. SuprSend and Knock run password resets, product alerts and engagement campaigns through the same workflows, users, preferences and logs. OneSignal sends transactional messages through its API, and its Journeys, segments and reports are built for campaigns. See how SuprSend handles transactional notifications.

Does OneSignal support WhatsApp, Slack or Microsoft Teams?

OneSignal's pricing page lists mobile push, web push, email, SMS and RCS, in-app messages and Live Activities, and no WhatsApp, Slack or Microsoft Teams. SuprSend sends on all three alongside email, SMS, mobile push, web push, in-app and webhooks. Pushwoosh, Knock and Braze support WhatsApp.

Which OneSignal alternatives are SOC 2 and HIPAA compliant?

SuprSend holds SOC 2 Type II and ISO 27001 and covers GDPR, HIPAA and CPRA; details are in the SuprSend trust centre. Pushwoosh lists ISO 27001:2022, a SOC 2 Type 2 report and HIPAA. Knock offers a HIPAA BAA on Enterprise. OneSignal's pricing page lists GDPR with a DPA on paid plans and a security and legal package on annual plans.

Can I self-host a OneSignal alternative?

SuprSend runs in your own VPC, on-prem or as bring your own cloud under an Enterprise licence, with vendor support; see SuprSend self-hosting. Novu's open-source core is free to self-host and you run it yourself. OneSignal, Pushwoosh, Knock, Airship, MoEngage, Braze and Customer.io are cloud only.

Do I still pay email and SMS providers with a OneSignal alternative?

With SuprSend and Knock you connect your own providers, such as Amazon SES, SendGrid or Twilio, and pay them directly; mobile push goes through FCM and APNs at no charge. OneSignal and Pushwoosh bundle email sending into their own pricing. SuprSend fails over to a second provider when the first does not confirm delivery.

Can I keep my push tokens when I leave OneSignal?

Yes. APNs and FCM tokens belong to your app. Export users, external IDs and tokens from OneSignal, import them into the new platform, and devices keep receiving push once the new SDK is live.
