# GigaCode

Use [OpenCode](https://opencode.ai)'s UI with any coding agent.

Supports Claude Code, Codex, and Amp.

This is __not__ a fork. It's powered by [Sandbox Agent SDK](https://sandboxagent.dev)'s wizardry.

> **Experimental**: This project is under active development. Please report bugs on [GitHub Issues](https://github.com/rivet-dev/sandbox-agent/issues) or join our [Discord](https://rivet.dev/discord).

## How It Works

```
┌─ GigaCode ────────────────────────────────────────────────────────┐
│ ┌─────────────────┐    ┌─────────────────┐    ┌─────────────────┐ │
│ │  OpenCode TUI   │───▶│  Sandbox Agent  │───▶│  Claude Code /  │ │
│ │                 │    │                 │    │   Codex / Amp   │ │
│ └─────────────────┘    └─────────────────┘    └─────────────────┘ │

```

- [Sandbox Agent SDK](https://sandboxagent.dev) provides a universal HTTP API for controlling Claude Code, Codex, and Amp
- Sandbox Agent SDK exposes an [OpenCode-compatible endpoint](https://sandboxagent.dev/opencode-compatibility) so OpenCode can talk to any agent
- OpenCode connects to Sandbox Agent SDK via [`attach`](https://opencode.ai/docs/cli/#attach)
