Competitor features and prices change often; check their current plan pages. tunr's raw TCP/UDP/TLS tunnels are experimental and the relay terminates TLS, so no tunnel is end-to-end encrypted.
If you need a simple tunnel with no extra features, both tools work, and ngrok's Personal plan costs less than tunr Pro. tunr's free tunnel has an open-source CLI and client-demo tools built in — freeze mode, demo mode, a feedback widget, QR codes, bearer token auth, TTLs and MCP tools for your coding agent.
This page compares tunr's tunnel (tunr share). tunr's main product is now Agent Bridge: approved, read-only, audited access for AI agents to customers' on-prem data. Tunnels & deploy are still part of tunr.
