Astrid

Capability-secure runtime that sandboxes each AI agent capability as a sealed WebAssembly component.

PlatformWebfreeglobal

Astrid is a portable, capability-secure runtime that treats each AI agent ability as a sealed WebAssembly component, granted only explicit authority and enforced by a small kernel that routes events, checks capabilities, runs the sandbox, and records an audit trail. Because authority is enforced by the kernel rather than trusted to the model's instructions, a jailbreak, poisoned tool, or bug still can't let an agent read a file, reach the network, or spawn a process outside what it was granted.
