0x0 Server

@anonymous-dev/0x0-server is the local runtime for AI-powered developer tools. It exposes one provider layer over OpenAI and Anthropic models. The primary app surfaces are server chat and server completions. Clients can call them through HTTP for simple requests or WebSocket for editor sessions, agent turns, cancellation, and change review.

What It Provides

Provider discovery through GET /providers
Streaming chat through POST /chat
One-shot code completion through POST /completions
One-shot inline edits through POST /inline-edit
Git-backed agent sessions over /ws
Worktree-based change review with accept and discard operations

Quick Start

# from the 0x0 repo
bun install

OPENAI_API_KEY=... ANTHROPIC_API_KEY=... bun run --cwd apps/server dev

The server listens on http://127.0.0.1:4096 by default. Set PORT to choose another port.
