OneSignal and Braze both send push, email, SMS and in-app messages from one dashboard. OneSignal started with push, publishes its prices and is used mostly by small teams. Braze began as Appboy in 2011, sells quoted contracts and is used mostly by mid-market lifecycle teams.

Need AI agents to build and run product alerts and campaigns end to end? Choose SuprSend
SuprSend is an agentic notification platform for product alerts and customer engagement messages, across email, SMS, push, WhatsApp, Slack, Microsoft Teams and an in-app inbox, with tenants, translations and preferences built in. Product alerts and marketing campaigns run through the same workflows, preferences and logs. An agent in Claude or Cursor can create a workflow, write its templates, test it and send, and engineers pull the same workflows into the repo with the CLI. OneSignal’s and Braze’s MCP servers manage users, segments or templates; neither builds a journey or a Canvas.

FAQ
Is OneSignal better than Braze?
OneSignalOneSignal is better for a small team that wants push, email and in-app messages live quickly on published, month-to-month pricing, with a free plan to start on.
BrazeBraze is better for a lifecycle team that needs branching journeys with experiments, warehouse-driven segments, WhatsApp or LINE, and a lasting in-app feed, and can support a quoted contract and a longer setup.
Which is cheaper, OneSignal or Braze?
They bill on different units. OneSignal charges a platform fee plus $0.012 per mobile monthly active user on Growth, with email and web push priced by send and subscriber. Braze sells quoted contracts and counts data points on profile updates, events and sessions, so OneSignal is the one you can price without a sales call.
Can I use OneSignal and Braze together?
Both SDKs can run in the same app, but each keeps its own users, subscriptions and opt-outs. A user who unsubscribes in one still receives messages from the other unless you sync the two, which is why most teams pick one.
What moves when switching from OneSignal to Braze?
Users move by external ID, OneSignal data tags become Braze custom attributes, custom events keep their names, and segments are rebuilt. Journeys are rebuilt as Canvases, templates are copied over, and both use Liquid for personalization. The app swaps one SDK for the other, and push credentials are added to Braze.
What if our notifications are product events owned by engineering?
SuprSend, which publishes this page, runs product alerts and customer engagement messages from workflows that engineers change from the repo and agents build over MCP.
