Compare SuprSend and Novu across multi-tenancy, channel coverage, workflows, and deployment — and pick the one that fits your stack.
Each tenant gets its own template version, provider, and sending domain, plus admin control over mandatory channels and the categories its users see. Tenants nest, so a sub-tenant inherits and overrides. Novu keeps tenants flat, shares one provider per environment and one template across all of them.
One send step reaches every channel a user is available on. Branch the run into separate paths, digest, delay, wait for an event, call a sub-workflow, hold to allowed hours in the user's timezone, fire a webhook, transform the payload. Novu chains each channel separately and puts a condition on each node instead of branching.
Users opt in or out per category, channel, pick a digest time, and get condition-based rules. Tenant admins set the defaults above them. Novu puts a toggle on each workflow, with no tenant layer, no digest control, and no condition rules.
Frontend SDKs coverage across web and mobile. SuprSend CLI pushes and pulls every asset, and promotes staging to production. Novu covers React and React Native, and its CLI pushes workflows but pulls only translations back. Test sends reach real recipients, there's no test mode.
See the exact content delivered, and why a send was blocked. Metrics stream to Datadog, New Relic, or any OpenTelemetry destination. Novu shows nothing when a send never goes out, and has no monitoring integration.
Run SuprSend in your own VPC or on-prem with the full product, your data stays where you need it. Novu's free open-source edition sends on every channel, but comes with limits enterprises run into fast: one team member, two environments, no RBAC or SSO, and no SOC 2 or HIPAA coverage.
83 line items across 10 categories below — SuprSend leads on 51, both are even on 27, and Novu leads on 5.
SuprSend
NovuBoth start from a user with channels and custom properties. The difference is what sits around that user: lists you can build from a query or a CSV, tenants that nest and send through their own provider, and objects that receive messages in their own right.

| Branding | Each tenant's branding auto-fills a shared template at send time | Each tenant's branding auto-fills a shared template at send time |
| Per-tenant sending | Each tenant sends via its own provider + domain | One provider per environment, shared by all tenants |
| Per-tenant preferences & controls | Tenant admin sets channel + category defaults, mandatory channels, and which categories users see | A user's preferences can differ by tenant — but no tenant admin defaults, mandatory channels, or hidden categories |
| Per-tenant content | A tenant can have its own content version with template variant, matched by tenant ID at send | No per-tenant version — every tenant shares one template |
| Objects | ||
| Objects as recipients | Objects — a non-person entity like an order, team, or device | Topics — a named group of people |
| Subscriptions & fan-out | Objects have their own channels, custom properties, and nesting | Topics only group people — no channels, no custom properties, no nesting |
The core five channels are native in both. SuprSend adds web push with no third-party provider, ships Slack and Teams as finished channels rather than a beta, and retries a failed send on the next provider on its own.
| Channel coverage | ||
| Email, SMS, push, in-app, WhatsApp | all native | all native |
| Web push | Native browser push (VAPID), no third-party needed | Only through third-party providers — no native web push |
| Team chat (Slack, MS Teams) | Slack + MS Teams, both live | Slack + MS Teams — in beta |
| Other chat (Discord, Telegram) | No Discord or Telegram | Discord (+ Mattermost, Zulip); no Telegram |
| Failover & routing | ||
| Provider failover | Auto-retry on next provider if one fails | No auto failover — switch providers by hand |
Both ship an inbox component rather than leaving you to build one. SuprSend covers more platforms, authenticates with an expiring token, and gives the component more room to be restyled, filtered and scoped to a tenant.
| Integration & customization | ||
| SDK coverage | Drop-in web component (React, Angular, Vue, JS); headless on mobile (React Native, Flutter, iOS) | Drop-in web component (React, Angular, Vue, JS); mobile headless — React Native only |
| Layout & styling | Bell dropdown, side panel, or full page; restyle fully, or build your own with headless hooks | Bell dropdown, side panel, or full page; restyle fully, or build your own with headless hooks |

The builder is the same idea on both sides; the range is not. Batching and digest, conditions that can check whether an earlier message was seen, version history with rollback, and cancelling a run already in flight are SuprSend only.

Rich editors on both sides, for every channel. SuprSend adds variants inside one template — per tenant, per language, per user — so a shared template can differ at send time, and keeps a version history you can roll back.

Novu keeps preferences per workflow, which is where they were declared. SuprSend moves them to categories and channels, adds a digest schedule the user picks, and lets a tenant admin set the defaults everyone starts from.
| Preference center | ||
| Embedded preference center | Drop-in preference centre in your app, or build your own with headless hooks | Drop-in preference centre in your app, or build your own with headless hooks |
| How it resolves | ||
| Notification categories | Workflows tagged to a category; the category carries its own defaults, digest, conditions | Toggles stay per workflow — Inbox can group them into sections for display only |
| Hierarchy & precedence | User's choice (per tenant) > tenant admin default > category default | Subscriber's choice > workflow default — no tenant layer |
| User controls | ||
| Channels per category | Opt in/out of each channel, per category | Opt in/out per channel — per workflow, not category |
| Digest / frequency | Users pick their digest schedule and time (e.g. instant, daily 9am) | No digest or frequency setting for subscribers |
| Condition-based rules | Attach custom conditions to a category (e.g. a number threshold, role, list) | No condition-based preference rules |
| Quiet hours | No do-not-disturb window users can set | Subscribers set daily quiet windows in local time |
| Unsubscribe link | Auto-generated unsubscribe page; drop the link into any email | No unsubscribe link added to emails |
Both record what was delivered. SuprSend records why it was not: the block reason, the vendor error and the rendered content, kept for longer and exported to S3, a warehouse or the monitoring tool you already watch.
| Debugging a notification | ||
| AI queries | Ask the Agent in the dashboard or Slack — a semantic layer over your notification data answers in plain English: delivery stats, engagement, why a notification failed | Only through a connected MCP tool like Cursor or Claude |
| Workflow execution | Step-by-step timeline per recipient — channel picked, template rendered, node errors | Step-by-step timeline per recipient — step status, provider response, and the trigger payload |
| Message log | One entry per message — delivery status, vendor error, and the exact content delivered | Message detail sits inside each run — no separate message view |
| Delivery failure reasons | Shows why it was blocked — opt-out, no channel, or template error | Shows which step failed, not why |
| Log search & filtering | Filter by workflow, recipient, tenant, status, date — idempotency key traces end-to-end | Filter by workflow, channel, recipient, status, date — transaction ID traces end-to-end |
| Log retention | 30 days on Free, 90 days on Business, custom on Enterprise | 24 hours on Free, 7 days on Pro, 90 days on Team, custom on Enterprise |
| Program dashboards | ||
| Analytics dashboard | Built-in dashboard — channel performance, volume, unsubscribes, workflow breakdown | Volume and engagement by channel, workflow, and provider — no template, category, or tenant breakdown, no unsubscribes, no failure analytics |
| Data export | ||
| Webhook events | Real-time status events to your endpoint | Real-time status events to your endpoint (Team+ plans) |
| Logs Export | Message & workflow logs auto-synced to S3 as Parquet — queryable in Athena (or any Parquet-compatible engine); importable to Redshift/Snowflake/ClickHouse | Streams events to ClickHouse, Snowflake, or Redshift with per-event-type field mapping — requires Webhooks (Team plan) |
| Observability tool integration | Notification metrics stream to Datadog, New Relic, or any OpenTelemetry destination — Grafana, Prometheus, Honeycomb, Dynatrace | No native integration — build it yourself off webhooks |
| Raw data export | CSV export, up to 50M rows | No bulk export or download |
Novu gives you an API, SDKs and webhooks. SuprSend adds the things that make it survive a team: separate environments, a CLI that pushes and pulls every asset, generated types, and a test mode that blocks real delivery.
| Environments | ||
| Environments | Sandbox, staging, production — sandbox is pre-configured | Development and production; more environments need Team/Enterprise |
| API | ||
| Ways to build | Dashboard, API, CLI, and MCP | Dashboard, API, CLI, and MCP |
| OpenAPI spec & Postman collection | Downloadable spec, Postman collection, and in-browser try-it | No spec download, Postman collection, or try-it explorer |
| SDKs | ||
| Backend SDKs | Python, Node, Java, Go | Python, Node, Java, Go, PHP, .NET — plus community Ruby and Kotlin |
| Frontend SDKs | JavaScript, React, React Native, Flutter, plus native iOS and Android | React and React Native only — no Flutter, iOS, or Android |
| Release cadence | Published versioning policy and changelog; old versions stay supported | Changelog for the React SDK only |
| CLI & CI/CD | ||
| Push & pull | Push and pull workflows, templates, schemas, events, categories, and translations | Pushes workflows written in code; only translations can be pulled back |
| Environment promotion | Promote staging to production from the CLI | Promote from the dashboard only (Team/Enterprise plans) |
| Type generation | Generate TypeScript types from your schemas | Types come built in if you write workflows in TypeScript — no generator |
| CI/CD integration | No ready-made GitHub Action — run the CLI in your pipeline | Ready-made GitHub Action — syncs on every commit |
| Local dev & testing | ||
| Test mode | Test Mode blocks real delivery | No test mode — test sends reach real recipients |
| Docs | ||
| Quickstarts & example apps | Channel quickstarts, use-case guides, and runnable example apps | Framework quickstarts and integration guides; no end-to-end app guides |

| Self-hosting & licence | Self-host in your own VPC or on-prem, or BYOC — Enterprise licence; SDKs are MIT, the core is closed | Self-host free — MIT-licensed core; enterprise features are paid |
Both expose an MCP server, so both can say they work with agents. What separates them is how much an agent can actually do once connected — read a dashboard, or build the workflow, send the broadcast and diagnose the failure.
| Build with AI | ||
| MCP server | Official MCP server — runs locally through the SuprSend CLI | Official MCP server — hosted by Novu, connect by URL |
| What MCP can operate | Users, tenants, objects, preferences, and workflows | Subscribers, preferences, workflows, integrations, and past notification runs |
| Agent skills & IDE setup | Instruction packs so Claude/Cursor build with SuprSend correctly; one command installs everything | Instruction packs for coding assistants; installed separately |
| AI in the dashboard | ||
| Prompt-to-workflow | Describe the outcome; the agent builds the workflow | Copilot builds the workflow — in beta |
| AI content generation | Drafts the actual message copy for email, SMS, push, WhatsApp, inbox | Copilot builds structure only — no message copy |
| AI analytics summaries | A semantic layer over your notification data — ask in the dashboard or Slack, get delivery stats, engagement, template performance, with charts | No AI analytics or summaries |

The certifications largely match. The difference is what sits around them: how far access control goes, whether you can run the whole product in your own cloud, and who answers when something breaks at 2am.

Self-hosting puts SuprSend inside your environment, so we want to be upfront about who owns what.
Your product involves in-depth notification use cases.
A workflow can wait for a condition, branch, send in defined time windows, reach every channel at once, or one at a time until they engage.
Your customers are companies with their own notification rules.
They nest sub-tenants, set default preferences, edit their own templates inside your product, and send through their own provider and domain.
Your users have their own preferences for each notification type.
They pick the channels, digest schedule, and threshold for each notification category in each tenant they belong to.
You need in-depth detail on every notification execution.
Every notification keeps its delivery status, the steps the workflow executed and failed at with the reason, and the exact content delivered in message logs.
You need to analyze in depth how your notifications performed.
The dashboard covers delivery, engagement, unsubscribes, and failures. Export raw data, stream metrics to your observability tool, or query the semantic layer from the Agent in dashboard or Slack App.
You want to build and run notifications with AI.
An MCP server for your IDE, and an Agent that manages every notification operation - building workflows, writing content, creating users, tenants and more.
You need to self-host on an open-source licence.
Run Novu's MIT-licensed core yourself, free, from day one. The enterprise modules are the paid part.
Your backend runs on PHP or .NET.
Official Novu SDKs cover both, plus community-maintained Ruby and Kotlin. SuprSend's backend SDKs are Python, Node, Java, and Go.
Your users set their own quiet hours.
They pick daily windows in the inbox, and snooze notifications there. In SuprSend you decide per notification whether a quiet window applies.
Your AI agent sends the notifications.
One package exposes your workflows as tools for OpenAI, LangChain, or the Vercel AI SDK. With SuprSend, your agent triggers workflows through the API.
Workflows are rebuilt, not converted — there is no export from Novu that maps onto another platform. Both run side by side, so the move can go one workflow at a time.

"We are a B2B platform and our customers expect notifications to carry their own branding not ours. We looked at Knock and Courier too but the per-tenant control was not at the level we needed without writing a lot of custom code. SuprSend had that built in already. Each tenant can have their own branding, preferences, provider setup and in-app feed."
"SuprSend made it possible for us to launch a full-fledged notification system within weeks. The integration process is seamless, especially since they provide libraries for all major languages, which fit our stack well, including Python and Vue. The initial setup was extremely easy for us, which was a key factor in choosing SuprSend."
"The workflow builder has branching built in. I set conditions based on user properties or event data and the flow splits accordingly. For our onboarding sequence new users get a welcome flow with helpful tips while returning users get a shorter reminder. This level of personalization used to require engineering work for every new condition. Now I manage it all from the dashboard."
