opencode

opencode is an open-source coding agent that runs in your terminal as a TUI. Built by the terminal.shop team, it ships with two agents (build for full access, plan for read-only) and works with Claude, OpenAI, Google, or local models. MIT licensed, no provider lock-in.

Setup is a one-line install via bash, brew, or your package manager of choice. A client/server split lets you run the agent on a remote box and connect from any machine. LSP support is built in. The desktop app is still in beta if you'd rather not live in the terminal.

Solo developers and small teams get the best deal. You bring your own model API key, you keep the data local, and you can switch providers without changing tools. Teams already paying for Cursor or Copilot don't need this. Use it if you want one open agent across every model you touch.

The catch: you manage your own model accounts and bills. No integrated subscription, no SSO, no team policy yet. If finance wants one invoice and security wants one audit log, this isn't there.
