OpenCode is a fully open-source AI coding agent that lives in your terminal — provider-agnostic by design, so you are never tied to one model vendor.
- Built by Anomaly Innovations (the SST / Serverless Stack team, creators of terminal.shop).
- MIT-licensed and open — code at github.com/sst/opencode.
- One of the fastest-growing dev tools ever — 160k+ GitHub stars and millions of monthly developers.
- Runs as a terminal UI, desktop app or IDE extension.
Bring any model; OpenCode gets out of the way and keeps your code private.
- 75+ providers — Anthropic, OpenAI, Google, or local models via Ollama.
- Client/server architecture lets you drive the agent remotely.
- MCP + LSP support for real, repo-aware code understanding.
- Privacy-first — it doesn’t store your code or context.
The tool is free and open source — you pay the model providers directly, nothing in between.
- No subscription, no markup — bring your own API key.
- Costs scale purely with your own model usage.
- Self-host or run locally for full data control.
OpenCode rewards control and punishes hand-holding — know which camp you’re in.
- Power users who want any model and zero lock-in.
- Privacy- or IP-constrained teams that must self-host.
- Terminal-first developers who live on the command line.
- Beginners who want a polished graphical editor.
- Anyone who would rather not manage API keys and spend.
No tool is perfect — the trade-offs to weigh:
- Setup & keys — you manage providers and API keys yourself.
- Terminal-only — no rich GUI if that’s what you want.
- Cost visibility — you track your own model spend.
- Rougher edges than polished commercial IDEs.
- ✓Truly provider-agnostic — 75+ models, zero lock-in
- ✓Free and open source (MIT)
- ✓Fast, keyboard-first terminal UI
- ✓Client/server design enables remote and mobile control
- ✓Huge, fast-moving community (160k+ stars)
- ✕You manage your own API keys and spend

- ✕Less polished than commercial IDEs
- ✕Output quality depends on the model you bring
Across GitHub, Reddit and Hacker News, developers praise OpenCode as the open-source agent that finally rivals the commercial tools — the provider-agnostic design and terminal speed come up constantly. The main friction is the initial setup and bringing your own keys, and a few note it assumes terminal comfort. Sentiment among power users is strongly positive.
OpenCode is built by Anomaly Innovations — the team formerly known as SST (Serverless Stack), creators of terminal.shop.
