OpenCode
OpenCode is an open source AI coding agent built for the terminal, with desktop and IDE clients alongside. It connects to 75+ model providers, configures language servers automatically, runs parallel agent sessions, keeps conversations locally in SQLite, and is built by the team behind SST.
- MIT licensing means genuine auditability, self-hosting and no exposure to vendor pricing changes
- Local model support is the only acceptable configuration for some regulated environments
- Local SQLite storage makes retention architecturally impossible rather than merely promised
- 75+ providers means switching models is a setting rather than a workflow migration
- A tool supporting every provider is optimised for none of them specifically
- No inline diffs or visual review flow to match an editor-first tool
- Configuration flexibility is configuration work
