OpenCode

Good fit for

Developers who want a coding agent that can switch providers and work with local models rather than lock to one vendor.

Why consider it

The homepage documents free included models, provider connections, parallel sessions and local model support. The guide describes image prompts and switching between planning and building.

Main limitations

The landing page promotes V2, while the intro guide includes V1 installation instructions. Both use the same binary name and can replace each other. Use version-specific install guidance. Image input requires a compatible model. Free hosted model use has data-storage caveats, so do not infer zero retention from local-client marketing.

Cost and access

The MIT-licensed agent is free, with some included free hosted models. Other connected providers or optional optimized-model services can cost extra; these are not bundled unlimited inference.

Getting started

Choose the current version from the official site, follow its matching installation docs, connect a model and plan a change before switching to build mode. Review diffs and tool permissions.
