Generative AI coding assistant for building, operating, and transforming software
OpenCode
Terminal‑native AI coding assistant, provider‑agnostic and extensible.
A fast, open‑source AI coding agent that runs in the terminal, supports any LLM provider, and offers a client/server TUI for local or remote workflows.
Overview
Overview
OpenCode is an AI‑powered coding agent designed for developers who live in the terminal. It works with any large language model—Anthropic, OpenAI, Google, or self‑hosted alternatives—so you stay free from vendor lock‑in while getting contextual code suggestions.
Capabilities & Deployment
The tool provides a full‑screen TUI built by neovim enthusiasts, and its client‑server architecture lets the backend run on a workstation while you interact from another terminal or a mobile device. Installation is a single curl script or via npm, Homebrew, or Arch packages, with the install path configurable through environment variables.
Community & Extensibility
Released under the MIT license, OpenCode encourages contributions and custom extensions. Whether you need quick snippet generation, remote assistance, or integration into CI pipelines, the agent adapts to a variety of terminal‑centric workflows.
Highlights
Provider‑agnostic LLM support (Anthropic, OpenAI, Google, local models)
Full‑screen terminal UI built for neovim users
Client‑server architecture enabling remote control (e.g., mobile)
Simple installation via script or package managers with configurable install path
Pros
- Works entirely in the terminal, no GUI overhead
- Flexible model backend reduces vendor lock‑in
- Open‑source MIT license encourages community contributions
- Lightweight client can be paired with any server implementation
Considerations
- Requires familiarity with terminal/TUI workflows
- No built‑in graphical IDE integration
- Performance depends on chosen LLM and network latency
- Mobile client currently limited to remote control, not full editing
Managed products teams compare with
When teams consider OpenCode, these hosted platforms usually appear on the same shortlist.

Fit guide
Great for
- Developers who spend most of their day in the terminal
- Teams that need a consistent AI assistant across different LLM providers
- Users who prefer a lightweight, scriptable coding aid
- Projects that value open‑source transparency and extensibility
Not ideal when
- Users who rely on full‑featured graphical IDEs
- Beginners uncomfortable with command‑line interfaces
- Environments without internet access to reach external LLM APIs
- Scenarios requiring deep IDE integration like automatic multi‑file refactoring
How teams use it
In‑terminal code generation
Generate functions or snippets directly while editing in neovim, reducing context switches.
Remote AI assistance from mobile
Run the server locally and control it via a mobile client to get suggestions on the go.
Provider‑agnostic experimentation
Swap between Anthropic, OpenAI, or local models without changing the client, enabling cost and performance testing.
Automated code review in CI
Integrate the CLI into CI pipelines to have the AI suggest improvements or catch simple bugs.

Frequently asked questions
How does OpenCode differ from Claude Code?
OpenCode is fully open‑source, not tied to a single provider, emphasizes a terminal UI, and uses a client‑server model that allows remote control.
Which language models can I use with OpenCode?
Any model that offers an API compatible with the OpenAI format works, including Anthropic, OpenAI, Google, or self‑hosted local models.
Can I run OpenCode on a headless server?
Yes. The server component can run on any machine, and you can connect via the TUI from another terminal or a mobile client.
How do I choose the installation directory?
The installer respects $OPENCODE_INSTALL_DIR first, then $XDG_BIN_DIR, $HOME/bin, and finally $HOME/.opencode/bin as fallbacks.
Is there a graphical client available?
Currently the primary interface is the terminal UI; a mobile client exists for remote control, but no full desktop GUI is provided.
