OtaKit: Open-source OTA updates for Capacitor apps
OtaKit is an open-source over-the-air update framework for Capacitor apps. It lets you push web updates directly to users without going through App Store or Google Play review, so you can ship fixes and features in minutes instead of waiting days.
How it works? Capacitor apps bundle a web layer (the actual app) inside a native shell. OtaKit replaces that layer remotely. You upload a new build via CLI, it gets published to a CDN, and the app downloads and applies it on the next launch or resume. If anything goes wrong, it automatically rolls back to the last working version.
Updates are served from a global CDN, so delivery is fast, scalable, and reliable by nature. Each release is verified with signed manifests (ES256) and SHA-256 hashes to prevent tampering. You can control how updates are applied with modes like next launch, next resume, or immediate, and use channels like staging, beta, and production to target different users.
Everything is open source under MIT. You can use the hosted version or self-host it for free. No lock-in.
Pricing is simple: free tier with 1,000 updates per month, Pro at $19 for 100,000 updates, Scale at $99 for 1,000,000 updates, with overage pricing beyond that. Except if you are reading this from Uneed (-> -55%).
