What's Good

Push (mobile+web), in-app, email, Journeys. Free still useful for small apps: web push (10k/send), 10k emails/mo, mobile push/in-app under the Free MAU cap. Mature SDKs and dashboard.

The Catch

Closed SaaS. From 2026: Free mobile push/in-app limited to 1,000 MAU (new orgs Sep 1, existing Oct 1) — overage pauses mobile until Growth (from about $19/mo + per-MAU). Not Novu/Knock twins. SMS/RCS extra.

Verdict

Messaging SaaS. Free for tiny MAU; Growth meters mobile hard after 1k.
