Strengths and tradeoffs
What each tool does well, and the limitations to keep in mind.
Pros
- Fully open source (MIT) with zero cost and no vendor lock-in — 2,900+ stars and 220K+ downloads
- True multi-agent parallelism with Git worktree isolation preventing conflicts between agents
- Provider agnostic supporting 23+ coding agent CLIs from all major providers
- End-to-end workflow from issue tracker to PR merge including diff review and CI/CD checks
- Remote SSH support enabling use with cloud dev environments and powerful remote hardware
Cons
- No built-in AI — requires separate paid subscriptions for each coding agent CLI
- Electron-based and can be resource-heavy when running 20+ agents concurrently
- Enterprise features like team management and auth are planned but not yet shipped
- Early-stage desktop app at v0.4.x — users may encounter stability issues
Pros
- Free plan with 50 credits a month
- Spec-driven workflow produces requirements and designs, not just code
- Choice of Claude, GPT, and open-weight models, with Auto mode
- Available as an IDE, CLI, web app, and mobile app
Cons
- Credit multipliers vary by model, so cost per task can be hard to predict
- Unused monthly credits don't roll over
- Free plan is limited to open-weight models and Claude Sonnet 4.5 with rate limits
- Enterprise sign-in runs through AWS IAM Identity Center
