What is OpenCode?

OpenCode is an open source AI coding agent that helps developers write code in the terminal, IDE, or desktop. It supports multiple LLM providers, local models, LSP integration, multi-session agents, and privacy-focused workflows.

OpenCode is an AI coding assistant and open source terminal-native agent that helps developers write, refactor, and debug code across the terminal, IDE, and desktop, with pricing starting free under the MIT license. It targets developers who want full control over their LLM provider, local model usage, and data privacy without vendor lock-in.

Built as a provider-agnostic alternative to closed-source tools like Claude Code and Cursor, OpenCode integrates directly with major LLM providers including Anthropic Claude, OpenAI GPT, and Google Gemini, and supports dozens more through aggregators like OpenRouter and LiteLLM — as well as local models via Ollama. The agent runs natively in the terminal as a TUI but also offers IDE plugins and a desktop interface, allowing developers to choose their preferred surface. Multi-session support lets engineers run several parallel agents on different branches or tasks simultaneously, while built-in LSP (Language Server Protocol) integration gives the agent the same code-intelligence context that modern IDEs use — improving accuracy on large codebases.

Key Features

✓Open source under MIT license
✓Multi-provider LLM support (direct and via aggregators like OpenRouter)
✓Local model support via Ollama
✓Terminal-native TUI interface
✓IDE and desktop clients
✓LSP integration for code intelligence

Pricing Breakdown

Open Source

Free
  • ✓Full access to OpenCode CLI, TUI, and desktop apps
  • ✓Bring your own API key for any supported LLM provider
  • ✓Local model support via Ollama (no API costs)
  • ✓Multi-session parallel agents
  • ✓LSP integration and IDE plugins

Typical API Costs (BYOK)

$5–$50/month

per month

  • ✓Anthropic Claude Sonnet: ~$3/M input, ~$15/M output tokens — typical developer ~$10–$30/month
  • ✓OpenAI GPT-4o: ~$2.50/M input, ~$10/M output tokens — typical developer ~$5–$20/month
  • ✓Google Gemini Pro: ~$1.25/M input, ~$5/M output tokens — typical developer ~$3–$15/month

Pros & Cons

✅Pros

  • •Fully open source under MIT license — auditable, forkable, and self-hostable for compliance-sensitive teams
  • •Provider-agnostic with direct support for major LLM providers and access to dozens more through aggregators like OpenRouter and LiteLLM
  • •Bring-your-own API key model means you only pay model costs — no per-seat subscription markup
  • •Native terminal TUI keeps developers in their existing workflow without forcing an IDE switch
  • •LSP integration provides accurate symbol resolution and refactoring across large codebases
  • •Multi-session support lets you run parallel agents on separate branches or tasks at the same time

❌Cons

  • •Steeper setup curve than turnkey tools — requires API key configuration and provider selection
  • •Smaller community and ecosystem compared to Cursor, Copilot, or Claude Code
  • •Quality depends entirely on the underlying model you connect — not a curated experience
  • •Limited polish in IDE plugins compared to first-party Cursor or VS Code Copilot integrations
  • •Documentation and onboarding still maturing as the project evolves rapidly

Who Should Use OpenCode?

  • ✓Terminal-first developers who want an AI coding agent inside tmux, iTerm, or Ghostty without switching to a new IDE
  • ✓Enterprise teams with compliance requirements that mandate self-hosted or auditable AI tooling
  • ✓Engineers who already pay for Anthropic, OpenAI, or OpenRouter API access and want to avoid duplicate per-seat coding-assistant subscriptions
  • ✓Privacy-conscious developers who need to run agents against local Ollama models with no data leaving their machine
  • ✓Power users who want to run multiple parallel agent sessions across different git branches or repositories simultaneously
  • ✓Open source maintainers and security researchers who need to audit, fork, or extend their AI tooling

Who Should Skip OpenCode?

  • ×You're concerned about steeper setup curve than turnkey tools — requires api key configuration and provider selection
  • ×You're concerned about smaller community and ecosystem compared to cursor, copilot, or claude code
  • ×You're concerned about quality depends entirely on the underlying model you connect — not a curated experience
