The models' case: Best overall for developer-led product teams: powerful cross-channel workflows, batching, digests, throttling, preferences, tenant-aware data, excellent in-app and mobile. The models' main caveat: The jump from 10,000 free messages to a $250/month plan is steep, and there is no self-hosted option. The strongest alternative is Novu — Best value and ownership story: open-core with an MIT-licensed core, self-hosting, code-first workflows, broad provider coverage, real-time Inbox and.
