What OpenCode is
OpenCode is an open-source coding agent that runs in your terminal, IDE, or as a desktop app. It emphasizes privacy: it does not store your code or context data.
Key features
- Open source - full source available.
- Privacy-first - no code or context stored by OpenCode.
- 75+ LLM providers - connect Claude, GPT, Gemini, local models, and more.
- LSP enabled - understands your codebase through language servers.
- Multi-session - work on several tasks at once.
- Share links - share conversation links with teammates.
Install
curl -fsSL https://opencode.ai/install | bash
Use case
OpenCode is a good fit for privacy-conscious teams that want an open-source agent with broad provider support. The promise of not storing code is meaningful for companies with strict data policies.
License
Open source; check the repository for the exact license.
Honest caveat
OpenCode competes in a crowded space. Its privacy stance is the clearest differentiator; compare feature depth against Cline and Kilo Code before choosing.
