About

IronClaw is a secure, open source runtime designed to run autonomous AI agents with strong built-in protections for credentials and system access. It positions itself as a security-focused alternative to OpenClaw, operating inside encrypted enclaves on the NEAR AI Cloud or locally to protect sensitive data throughout execution. It enables users to deploy AI agents quickly through one-click setup while keeping API keys, tokens, and passwords stored in an encrypted vault that the AI itself cannot directly access. IronClaw isolates every tool inside its own WebAssembly sandbox with capability-based permissions and strict resource limits, preventing compromised skills from affecting other parts of the system. It is built in Rust to enforce memory safety at compile time and eliminate common exploit classes such as buffer overflows and use-after-free errors.
