TunnelCrib overlaps with Teleport's reverse-Tunnel access model, but is currently a much narrower secure connectivity product.
| Area | TunnelCrib | Teleport |
|---|---|---|
| Primary purpose | On-demand Tunnel to a Service on a Device | Identity-aware access platform for infrastructure |
| Connectivity | Direct TunnelCrib Client and Agent path first; TunnelCrib Relay or Private Relay fallback | Agent-initiated reverse tunnels through Teleport Proxy |
| Protocols | Remote shell, remote desktop, remote management, HTTP/HTTPS, and custom TCP ports | SSH, Kubernetes, databases, desktops, web apps, and more |
| Authentication | Organization and Device registration, ECDSA P-256 nonce proof, and per-Tunnel SSH credentials | Central CA, SSO/IdP integration, and short-lived user and machine certificates |
| Authorization | Agent-advertised Services plus per-Client Agent-access policy (allow/deny, per Service) | Mature RBAC, labels, access requests, and just-in-time elevation |
| Audit | Durable activity log of connects, Tunnels, and transport; no session recording/replay yet | Comprehensive audit events, session recording/replay, and command/query auditing |
| Data plane | Direct encrypted SSH-over-P2P where possible; Relay only when required | Usually proxy/reverse-tunnel mediated, with multiple routing modes |
| User experience | TunnelCrib Client selects a Device and Service | Web UI and CLI resource catalog with identity-driven access |
The key architectural difference is that TunnelCrib creates an encrypted TCP Tunnel to a selected Service, then lets the user's normal local tool use it. Teleport is an identity and policy control plane that understands the accessed resource type and enforces user and role policy throughout the session.
TunnelCrib's differentiators are direct P2P preference, simple fixed/custom Service ports, Private Relays, and per-Client Agent-access policy with a durable activity log. To approach Teleport's scope, the major additions would be SSO, user roles and resource policy, certificate authority and lifecycle, session recording/replay, and resource-specific gateways.
