OpenCode

OpenCode is an open source AI coding agent that integrates model-powered assistance into the terminal, your editor, or a cross-platform desktop app. OpenCode helps developers write, review, and debug code inline by offering contextual edits, stepwise debugging prompts, and multi-agent orchestration without switching tools.

It supports 75+ LLM providers through Models.dev and can route requests to hosted APIs or local models you manage. LSP integration injects completions, diagnostics, and code actions directly into editors.

Run parallel agents—for example, one agent to refactor a module, another to generate unit tests, and a third to audit dependencies—and capture their states with shareable session links.

Optional connections to GitHub Copilot and ChatGPT Plus let teams use existing accounts, and a CLI and desktop GUI fit different workflows.

Backend and frontend engineers use OpenCode to scaffold features, refactor legacy code, and generate comprehensive tests. QA engineers, SREs, and devops teams build agents that triage incidents, propose configuration fixes, and produce reproducible steps. Open-source maintainers and reviewers share sessions to reproduce bugs during pull request reviews, and educators use the desktop app for live coding demonstrations.

OpenCode provides a free tier for basic use; paid plans unlock higher concurrency, private model hosting, team management, and enterprise features. Expect some setup for API keys or local model installation, platform-specific desktop integrations, and model-dependent output quality. The project is open source, maintained on GitHub, and backed by community documentation and issue tracking.
