Show HN: ButterClaw β AI agent runtime security, SIGKILL on breach, no cloud
π¦ ButterClaw Runtime security enforcement for autonomous AI agents. Every AI agent security tool I evaluated was either cloud-hosted, required an API key pointed at a vendor, or logged what your agent did without stopping it. ButterClaw is a self-hosted security layer that intervenes β before the LLM call, after it, and before each tool execution β and executes hard responses when something goes wrong.

π¦ ButterClaw Runtime security enforcement for autonomous AI agents. Local LLM reasoning. No cloud. No telemetry. SIGKILLs rogue processes. Every AI agent security tool I evaluated was either cloud-hosted, required an API key pointed at a vendor, or logged what your agent did without stopping it. ButterClaw is a self-hosted security layer that intervenes β before the LLM call, after it, and before each tool execution β and executes hard responses when something goes wrong. Not affiliated with butterclaw.ai, OpenClaw, or any OpenClaw forks. ButterClaw Tech has its own architecture, runtime, and execution semantics. Looking for a hosted agent framework? β butterclaw.ai or OpenClaw. Looking for a local-first kinetic security layer? β You're here.
