What is nullclaw?
NullClaw is an autonomous AI agent runtime built in Zig as a single binary with no dependencies. It has built-in model providers, tools, memory, and a multi-channel gateway, so you can run agents locally or deploy them to production. In terminal mode, a person can watch and use it interactively; in gateway mode, it can handle background tasks without human supervision. Combined with the NullHub ecosystem, you can stream in real time and approve actions from a browser dashboard.
- A model multiplexer that supports OpenRouter, OpenAI-compatible APIs, and custom endpoints
- Built-in shell, file, and search tools, with auto-approve and deny lists and a sandbox
- Terminal, WebSocket, and headless gateway channels
- Automatic context compaction, and session saving and restoring after a restart
- 678KB static binary, about 1MB of memory, startup in under 2ms
- 50+ providers, 19 channels, 35+ tools, MCP, and subagents
Who uses nullclaw and for what
