How does OpenCode compare with the alternatives?
Claude Code runs Anthropic's models, and every paid Claude plan includes it. OpenCode runs any provider but cannot use a Claude Pro or Max plan, which Anthropic prohibits, so Claude in OpenCode means API or cloud-provider billing. Choose by whether Claude is your only model.
Codex comes with ChatGPT plans and starts inside a sandbox. OpenCode can sign in with ChatGPT Plus or Pro too and adds every other provider, while its default policy allows edits and commands with no sandbox. The question is how many model vendors your engineers need.
Both are open-source terminal agents on your own keys, local models included. Aider pair-programs on the files you add and commits each change to git, and its latest release shipped on February 12, 2026. OpenCode adds subagents, a server, and desktop and web clients, and ships several releases a week.
Both are open source and run on the provider you choose. Cline lives in VS Code and JetBrains IDEs and asks before each edit and command by default. OpenCode is terminal-first, serves every client from one local server, and allows actions by default.
