Show HN: OtaKit – open-source, self-hostable OTA updates for Capacitor apps

OtaKit is a newly released open-source tool that lets developers push over-the-air (OTA) updates to mobile apps built with Capacitor (a popular framework from Ionic that wraps web code — HTML/CSS/JS — into native iOS and Android apps). Normally, updating a mobile app requires submitting a new binary to app stores and waiting for approval. OTA updates skip that by patching just the web-layer code directly on the user's device, similar to how React Native's CodePush or Expo's updates work. OtaKit positions itself as a self-hosted, no-vendor-lock-in alternative to those services. For developers who want to control their own update infrastructure — for compliance, cost, or privacy reasons — OtaKit offers a server you run yourself and a client plugin that checks for new bundles. The project was just shown on Hacker News (Show HN), which explains the launch-day README and early stage.
