Sentinel: Self-Hosted Agent Platform for Claude Code Subscribers
Sentinel is a self-hosted agent platform that runs on your existing Claude Code OAuth token, eliminating API overhead. The project is fully open source under AGPL-3.0 license with no cloud dependencies.
Platform Features
Sentinel adds several layers of functionality around Claude:
- Clean operator UI with real-time browser automation via built-in VNC
- araiOS control layer for defining custom skills with granular approval rules per action
- Git gating system where agents run freely on local work but require explicit confirmation for pushes or pull requests
- Full session trace logs showing exact context per run
- Structured hierarchical memory with pinning and scoped nesting capabilities
- Cron and heartbeat triggers for recurring automation tasks
Technical Details
The platform requires an existing Claude subscription to run. Since it uses your Claude Code OAuth token directly, there's no additional API cost or overhead. The self-hosted nature means you maintain full control over your data and infrastructure.
