OpenComputer
Digger
Background agent cloud that runs TypeScript agents on hardware-isolated Linux microVMs, with secrets the agent never sees.
Key features
- Agent as a TypeScript Function: Declare a model, tools and MCP servers inside one exported function and deploy it live with `opencomputer deploy` — the platform owns the agent loop, sessions, streaming and versions.
- Full Linux MicroVM Per Session: Each run gets a real machine with bash, a read-write filesystem, apt/npm/pip package installs and full network egress, isolated at the hardware level via KVM.
- Durable Steerable Sessions: Runs stream to the client, accept mid-run steering, hibernate automatically when idle and resume exactly where they left off instead of restarting.
- Origin-Bound Secret Injection: Secrets are defined per connection and injected only after a request leaves the sandbox, so the agent can act with a token it can never read or exfiltrate.
- Checkpoint and Fork: Named snapshots work like git branches for VMs — fork a prepared machine to try five approaches in parallel, or restore one at any time.
- Scheduled Autonomous Runs: A `defineSchedule` cron entry keeps a deployed agent running on its own, with sessions, streaming, MCP and Slack delivery handled by the platform.
- Model-Agnostic Passthrough: The model is just a string that can change per request; token usage is passed through at raw API rates with no markup, or drops to zero with your own key or subscription.
- Bare Sandboxes API: `Sandbox.create()` exposes the same microVMs directly — checkpoint, fork and live resize — for teams that want to bring their own harness and own the loop.
Best for
- Codebase Hygiene Bots: Deploy an agent that finds stale feature flags still referenced in code and opens a cleanup pull request for each one on a weekday schedule.
- Background Coding Agents: Hand off long refactors or migrations to an agent that clones the repo, runs the test suite in a real shell and works while you sleep.
- Media and Data Pipelines: Run agents that need heavyweight binaries such as ffmpeg or headless Chromium, which serverless function runtimes cannot host.
- Parallel Approach Exploration: Checkpoint a machine once the environment is prepared, then fork it to evaluate several agent strategies from an identical starting state.
- Safe Third-Party API Automation: Let an agent operate on GitHub, Slack or an internal API through origin-bound credentials it is structurally unable to read or redirect.
- Custom Agent Harness Hosting: Use the bare sandbox API as compute for an in-house agent framework, keeping your own loop while outsourcing VM lifecycle and scaling.
