A minimal, extensible terminal coding agent you can reshape
Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
Open-source React chat UI building blocks — ship an LLM interface in hours, not weeks.
Tune the chat interface to match your product with configurable components and theming options rather than fighting a locked-down widget.
Handle file uploads, embedded content and markdown formatting out of the box, so conversations can carry richer information than plain text.
Switch between different AI models, or mix several models inside the same interface to serve different tasks.
An intuitive but flexible API designed so you can compose custom chat experiences without disproportionate glue code.
