OpenCode

OpenCode is an open-source, terminal-native coding agent that is model-agnostic, letting you run any LLM provider or local model against your repository.

Overview

OpenCode grew rapidly by being the neutral option in a market of vendor-owned agents. Configure any provider with your own keys, use local models through Ollama or LM Studio, and get a polished terminal UI with a desktop app and IDE extensions alongside it.

Its curated model list, OpenCode Zen, surfaces models that actually work well for agentic coding, saving teams from benchmark guesswork. The project supports MCP servers, LSP integration and session management, and its MIT license and huge community make it the default choice for teams wary of lock-in. Because you can mix providers per task, teams routinely use cheap models for routine edits and stronger ones for hard problems. Session tooling keeps long projects organized across days of work.

Key Features

• Model-agnostic: bring any provider, key or local model
• Terminal-native UI with desktop app and IDE extensions
• OpenCode Zen curated model list for agentic coding
• MCP server and LSP integration for tooling and intelligence
• Session management with resumable agent conversations
• MIT-licensed and fully open source
• Large community with frequent releases

Pricing

OpenCode is completely free and open source. You pay only for whatever model provider you connect, and using local models makes the entire stack free apart from your hardware. The tool itself is free forever, and cost optimization is entirely in your hands through model selection and local inference.

Who Is It For

OpenCode is for developers who want control over model choice and cost, privacy-conscious teams running local models, and organizations that will not build workflows on vendor-owned tooling. It is also a favorite among tinkerers who like to extend their tools. It also appeals to security-conscious organizations, since code and keys can stay within their own environment with self-run models.

FAQ

Is OpenCode free to use?

Yes, OpenCode is free and open source with no paid tier. Model costs are whatever your chosen provider charges, including nothing for local models.

Does OpenCode offer an API?

OpenCode is a local agent rather than a hosted service, but its server can be driven programmatically and integrated into scripts, CI jobs and custom tooling.

How does OpenCode compare to alternatives?

OpenCode trades the tightest vendor-specific optimizations for freedom: any model, any provider, no lock-in. Versus Claude Code or Codex it may require more setup, but it is the option that will never be taken away or repriced underneath you. OpenCode is the strategic choice against lock-in; teams that want maximum polish from day one may still prefer a vendor’s integrated agent.
