Should you use InstaTunnel or Tailscale?
Use InstaTunnel for public localhost URLs and webhook callbacks. Use Tailscale when all participants are inside your private device mesh and public URLs are not required.
Tunnel comparison
InstaTunnel vs Tailscale
Tailscale is excellent for private mesh access between devices. InstaTunnel is for public HTTPS URLs that external webhook providers, clients, and QA testers can reach.
What Tailscale is
Tailscale is a private WireGuard-based mesh network that connects trusted devices and services without exposing them publicly.
Choose InstaTunnel for
- External webhook providers that need public HTTPS endpoints.
- OAuth callbacks registered with third-party identity providers.
- Client demos where the reviewer should not join a private mesh.
- MCP endpoints that need public HTTPS access.
Choose Tailscale for
- Private access between your own machines and services.
- Remote development inside a trusted team mesh.
- Internal tools that should not receive public internet traffic.
