New: CI tokens for every pipeline
Always deployed. Released when you’re ready.
Add Zephyr to the bundler you already use and every build deploys to its own live URL. Production only changes when you release, and rolling back is instant, on any cloud. Built by the team behind Module Federation.

Everything between build and production
Zephyr hooks into the bundler you already use, so deployment becomes a side effect of your build.
- Immutable versionsEvery build becomes a permanent snapshot with its own preview URL, so you can test real deployments before anyone else sees them.Learn more
- Tags & environmentsPromote versions through staging and production with rule-based tags and custom domains.Learn more
- Instant rollbacksSwitch traffic back to a version already running on the edge. No rebuild, no upload, no waiting.Learn more
- Remote dependenciesResolve Module Federation remotes at build time instead of hard-coding URLs and coordinating versions by hand.Learn more
- Locked environmentsFreeze production after a release so no deployment or config change lands until someone unlocks it.Learn more
- React Native OTABetaShip Metro Module Federation bundles to installed apps without another App Store or Play Store release.Learn more
