Capgo

Capgo is a console and backend for delivering live updates to Capacitor apps. A JavaScript bundle goes straight to installed devices instead of queuing behind an app store review, which is what makes the plugin behind it the stated alternative to Ionic Appflow.

The production deployment runs on Cloudflare Workers and Supabase. Workers take almost all the traffic by running the same backend code through a Hono adapter, which the maintainers say is roughly ten times cheaper at their scale, while Supabase stays the reference backend and handles internal calls and scheduled jobs. A self-hosted install needs only Supabase.

The update pipeline is built around a handful of ideas.

• Bundle management: bundles are uploaded, assigned to a channel and rolled back when needed.
• Channels: environments are handled as channels, and a single device can be pinned to one for QA or debugging.
• Delta updates: only the changed files are downloaded, which keeps an update small.
• Security: each update is encrypted and signed before it reaches a device.
• Rollback: an incompatible bundle resets the app to the last working one.
• Statistics: deployment numbers are reported per app.

Android and iOS are both covered, across Capacitor 5 through 8, and the maintainers say more than 3000 projects use it. The license is AGPL and the backend can be installed on your own infrastructure, so a team that dislikes the hosted console is not stuck with it.
