Pros & cons
- Fully MIT-licensed and auditable, giving developers complete transparency and control over the harness
- Supports ten CLI agent providers out of the box and reuses subscriptions already being paid for, avoiding redundant costs
- Active cross-platform release cadence covering macOS, Windows, and Linux with consistent updates
- Local mode requires the host machine to stay awake and running, which is impractical for overnight or long-running tasks without a cloud plan
- All paid tiers beyond the free Solo Local plan are fully sales-gated with no published pricing, making budget planning difficult
- Completely free and open-source with no usage-based fees
- Full control over data, infrastructure, and agent logic
- Active GitHub community and transparent development roadmap
- Requires technical expertise to set up and self-host
- No managed cloud version, so teams must handle their own infrastructure
