TunnelCrib vs. ZeroTier
ZeroTier creates encrypted virtual networks. Devices join a network, receive virtual networking state, and communicate according to centrally distributed rules. TunnelCrib deliberately operates at a narrower boundary: a Client receives a temporary local Tunnel to one approved Service on one registered Device.
| Area | TunnelCrib | ZeroTier |
|---|---|---|
| Access unit | One protocol Service on one Device | Member Device and virtual-network flows |
| Network layer | Application/TCP forwarding over SSH | Virtual network interface with IP-style connectivity |
| Path | Direct P2P first, TunnelCrib Relay fallback | Peer-to-peer overlay with relay/root assistance |
| Policy | Organization, Client, Agent, Device, and Service authorization | Network membership, node authorization, and distributed flow rules |
| Persistence | Session-oriented and temporary | Persistent network membership while the node is joined |
| Best fit | Least-exposure support or operational access | Private IP connectivity between many Devices, sites, and networks |
Choose TunnelCrib when…
- network membership would grant more reach than the task requires
- the user needs one database, web, SSH, RDP, or custom TCP Service
- the access request and session should be explicit and auditable
Choose ZeroTier when…
- many Devices need ongoing private IP connectivity
- virtual network interfaces, routing, or site-to-site connectivity are required
- distributed rules should be enforced by network members
The products can be combined: ZeroTier can connect infrastructure while TunnelCrib gives a support user a temporary Service-level path that avoids adding another network member.
