AI coding agent, built for the terminal.

This is a fork of the original opencode project

To build opencode locally as a single binary:

• Bun - JavaScript runtime and package manager
• Go 1.24.x - For the TUI component

If you're using asdf for version management, ensure you have Go 1.24.4+ available:

asdf list golang  # Check available versions

1. Install Bun (if not already installed):

   curl -fsSL https://bun.sh/install | bash
   export PATH="$HOME/.bun/bin:$PATH"

2. Build the Go TUI component:

   cd packages/tui
   CGO_ENABLED=0 GOOS=darwin GOARCH=arm64 go build -ldflags="-s -w" -o ../opencode/dist/tui ./cmd/opencode/main.go

   Note: Adjust GOOS and GOARCH for your target platform (e.g., GOOS=linux GOARCH=amd64 for Linux x64)

3. Build the main binary:

   cd packages/opencode
   mkdir -p dist
   bun build \
     --define OPENCODE_TUI_PATH="'/absolute/path/to/opencode/packages/opencode/dist/tui'" \
     --define OPENCODE_VERSION="'local-build'" \
     --compile \
     --target=bun-darwin-arm64 \
     --outfile=dist/opencode \
     ./src/index.ts

   Note:

   • Replace /absolute/path/to/opencode/ with your actual project path
   • Adjust --target=bun-darwin-arm64 for your platform (e.g., bun-linux-x64)

4. Test the binary:

   ./dist/opencode --version
   ./dist/opencode --help

The resulting binary at packages/opencode/dist/opencode is self-contained and ready to run on your target platform.

# YOLO
curl -fsSL https://opencode.ai/install | bash

# Package managers
npm i -g opencode-ai@latest        # or bun/pnpm/yarn
brew install sst/tap/opencode      # macOS and Linux
paru -S opencode-bin               # Arch Linux

The install script respects the following priority order for the installation path:

1. $OPENCODE_INSTALL_DIR - Custom installation directory
2. $XDG_BIN_DIR - XDG Base Directory Specification compliant path
3. $HOME/bin - Standard user binary directory (if exists or can be created)
4. $HOME/.opencode/bin - Default fallback

# Examples
OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash

opencode is an opinionated tool so any fundamental feature needs to go through a design process with the core team.

However we still merge a ton of PRs - you can contribute:

• Bug fixes
• Improvements to LLM performance
• Support for new providers
• Fixes for env specific quirks
• Missing standard behavior
• Documentation

Take a look at the git history to see what kind of PRs we end up merging.

To run opencode locally you need.

• Bun
• Golang 1.24.x

And run.

$ bun install
$ bun dev

API Client: After making changes to the TypeScript API endpoints in packages/opencode/src/server/server.ts, you will need the opencode team to generate a new stainless sdk for the clients.

It's very similar to Claude Code in terms of capability. Here are the key differences:

• 100% open source
• Not coupled to any provider. Although Anthropic is recommended, opencode can be used with OpenAI, Google or even local models. As models evolve the gaps between them will close and pricing will drop so being provider-agnostic is important.
• A focus on TUI. opencode is built by neovim users and the creators of terminal.shop; we are going to push the limits of what's possible in the terminal.
• A client/server architecture. This for example can allow opencode to run on your computer, while you can drive it remotely from a mobile app. Meaning that the TUI frontend is just one of the possible clients.

The other confusingly named repo has no relation to this one. You can read the story behind it here.
