OpenHands

OpenHands (formerly OpenDevin, from All Hands AI) is an open-source AI agent platform for software engineering work. Instead of a chat-first copilot, it runs autonomous agents that can plan multi-step tasks, execute code in a sandbox, edit files, open pull requests, review diffs, migrate legacy code, and investigate incidents. The core project is on GitHub with 77K+ stars, and the hosted product wraps it with an Agent Canvas workspace, cloud execution, RBAC, audit logs, and cost controls.

It is model-agnostic and works with Claude, Gemini, OpenAI Codex/GPT, and others, which matters if you already have a preferred LLM contract or want to swap models per task. Pricing is a genuine freemium: the OSS version is free forever for individuals who want to self-host, a paid Team tier adds shared org features, and Enterprise is quote-based for platform teams running it against large or regulated codebases. There is also an OpenHands SDK for building custom agent integrations.

Integrations cover GitHub, GitLab, CI/CD, Slack, PagerDuty, and ticketing tools, which positions it more as an internal developer platform component than a solo IDE assistant. The main caveats are the usual autonomous-agent ones: cost can spike on long-horizon tasks, and quality still tracks whatever frontier model you point it at.
