¿Qué es 21tunnel?

Mint a master key once — your AI assistant runs autonomously with scoped, short-lived child keys and instant cascade revoke. Built for Claude Code, Cursor, Aider, Devin. Also a complete open-source ngrok alternative in Rust: HTTP, TCP, SSH and gRPC tunnels, sticky subdomains, custom domains on the free tier, edge auth, live request inspector, team RBAC and audit logs. Self-host the whole stack free forever under MIT and Apache-2.0. No tier-locked security features.
