OtaKit

OtaKit helps Capacitor teams ship web-layer updates without waiting for app store review. It provides an over-the-air update workflow for JavaScript and asset changes, allowing teams to publish a native app once and deliver updated web bundles to installed devices in the background.

OtaKit is designed for teams that need faster fixes, staged rollouts, and more control over their Capacitor release process. The core is open source and can be self-hosted, while the managed service provides a simpler way to operate updates. Its workflow combines a CLI, dashboard, and AI agent support for preparing, checking, releasing, and monitoring updates.

Key Features

Instant Update Delivery

Send web-layer updates to installed apps in seconds without waiting for app store review. This makes it possible to address supported JavaScript and asset changes through the OTA release process.

Delta Updates

Devices download only the files that have changed rather than receiving the complete web bundle each time. This can help reduce payload sizes for apps with larger asset collections.

Release Channels

Release updates to production, beta, or custom channels depending on your rollout strategy. Channels can also be switched at runtime, giving teams more control over which devices receive particular releases.

Automatic Rollbacks

Revert problematic releases and allow broken updates to fall back automatically. Any release channel can be reverted when a deployment needs to be pulled back.

Compatibility Checks

The OtaKit CLI checks for native compatibility issues before an update is released. This helps catch changes that cannot safely be delivered through the web-layer update mechanism before they reach devices.

Custom Update Behavior

Silent updates are supported by default, while teams can hook into update events to build their own behavior. For example, an app can ask users before downloading an update or prompt them to restart after the update is ready.

Security Controls

Protect update delivery with signed manifests, SHA-256 verification, and HTTPS. OtaKit also supports optional end-to-end encryption for code.

AI Agent Support

Claude Code or Codex can assist with preparing updates and checking compatibility before release. The workflow can stop for approval before an update is delivered to devices, keeping a human approval step in the deployment process.

Dashboard and Device Activity

Track bundles, releases, and device activity through the dashboard in real time. This gives teams visibility into what was published and where updates have been delivered.

Open Source and Self-Hosting

The core is MIT licensed and can be run on your own infrastructure. Teams can choose between self-hosting OtaKit or using the managed service depending on how much infrastructure they want to operate themselves.

Built For Faster Capacitor Releases

OtaKit is built for teams that want a faster release path for web-layer changes without building or maintaining a complex update system. The workflow separates the native app release from supported JavaScript and asset updates, allowing teams to continue improving installed apps after the initial store release.

Common Use Cases

• Shipping JavaScript updates to installed Capacitor apps
• Delivering asset changes without waiting for app store review
• Releasing urgent web-layer fixes
• Running beta and production update channels
• Testing updates with custom release channels
• Reducing update payload sizes with delta updates
• Rolling back problematic releases
• Checking native compatibility before deployment
• Using AI agents to prepare and validate releases
• Self-hosting an OTA update infrastructure
• Monitoring bundles, releases, and device activity

Why It Matters

For Capacitor teams, not every app change requires a new native build. OtaKit provides a dedicated path for supported web-layer changes, allowing teams to publish updates to installed devices without going through the full app store review cycle.

The combination of delta updates, release channels, rollback support, compatibility checks, security controls, and real-time device visibility makes it more than a simple upload mechanism. Teams can control how updates are prepared, staged, delivered, and reverted while keeping the native application release separate.

Pricing

OtaKit pricing is based on live updates delivered, rather than seats or tracking.
