What Is OpenCrabs AI Agent?

OpenCrabs AI agent is a self‑hosted chatbot that can talk, answer questions, run tools, and learn from your interactions.
It is written in Rust, which makes it fast and safe.
OpenCrabs AI agent can connect to many popular AI models, such as Claude, Gemini, and OpenAI, through a single API endpoint.
The agent can also run local tools like a web browser, a file system explorer, or a custom script.
Because it runs on your own machine, you control the data and the privacy.

Key Features

• Self‑learning – The agent remembers what you like and adapts its responses.
• Self‑healing – If a tool fails, the agent can retry or switch to another tool.
• Multi‑profile support – Run several independent agents from one installation.
• Profile export/import – Share your agent’s personality with friends.
• Token‑lock isolation – Prevent two agents from using the same API key at the same time.
• CLI and TUI – Use a command‑line interface or a text‑based user interface.
• Open‑source – All code is on GitHub, so you can audit or contribute.
