OpenHands

Code less, make more: Your AI co-developer that actually ships.

Tool's Alternatives
  • Devin AI: Smoother UI but closed-source ($49/month). Lacks self-hosting.
  • Aider CLI: Lightweight for simple edits. No visual tools or Slack integration.
  • Replit AI: Best for education. Limited to Replit's cloud IDE.
  • Codium: Focuses on test generation. Can't refactor entire codebases.
Frequently Asked Questions

How much does OpenHands cost?
The core toolkit is free forever under MIT license. Cloud hosting starts at $20/month with included credits. Enterprise self-hosted licenses require a quote but include SLAs.

Can it work offline without APIs?
Absolutely. Use local LLMs like Llama 3 via Ollama. All operations run in your Docker environment—no internet needed after setup.

What’s the largest project it handled?
Documented case: a 28,000-file monorepo. Took 12 hours to refactor, but human effort was 3 hours of review versus 3 weeks manually.

How does it avoid introducing vulnerabilities?
The sandbox blocks unsafe commands (e.g., `rm -rf /`). Code changes trigger built-in SAST tools. Claude 3.5 shows 26% fewer security flaws than GPT-4 in tests.

Can I customize its behavior?
Yes, via microagents—YAML files defining workflows. One user created an agent that enforces ADA compliance in CSS.

Does it support mobile development?
Flutter and React Native are fully supported. Kotlin/Swift requires Claude 3.5 or higher for best results.

What if it writes broken code?
The self-debugging agent reruns tests, checks error logs, and iterates. Users report 83% of tasks complete without intervention.

How do I monitor its work?
Real-time logs show every file edit and command. The UI highlights pending actions in yellow, completed steps in green.

Is my code used for training?
Never. Your code stays in your runtime. Cloud LLMs only receive prompts you approve.

Can it pair with junior developers?
Yes—it explains each change in plain English. Teams at IBM use it for onboarding, reducing mentorship time by 70%.

What languages does it handle best?
Python, JavaScript, TypeScript, Java, C#, and Go have 90%+ success rates. COBOL requires manual oversight.

How fast is it compared to humans?
Benchmarks show 4.2x faster on boilerplate (forms, APIs) but only 1.3x on novel algorithms. It’s your tireless assistant, not a replacement.
