Secure tunnels, custom domains
Expose any local service to the internet with a secure tunnel domain. Custom subdomains, additional domains for extra ports, multi-port path routing, and automatic cleanup.
How tunnels work
From install to public URL in under a minute.
Install the tunnel client
Install the tunnel client for your OS. The MR Multi Model AI Coder extension detects it automatically and prompts you if missing.
Create a Domain
Pick a subdomain (e.g. my-workspace) and click Create. DNS is configured automatically — your public URL is ready in seconds.
Add More Domains
Need to expose a dev server or API? Click "Add Domain" to create additional tunnels for any local port with their own subdomains.
Install the tunnel client
Tunnels require a lightweight tunnel client. One command for your platform:
macOS
brew install cloudflared
Windows
winget install Cloudflare.cloudflared
Linux
sudo apt install cloudflared
See the CLI Reference for Chocolatey, Scoop, RHEL, Arch, Docker, and manual binary downloads.
Tunnel limits by plan
Free accounts get 1 device and 1 tunnel domain. Subscribe to unlock more.
| Plan | Price | Devices | Tunnel Domains | Custom Subdomains |
|---|---|---|---|---|
| Free | $0 | 1 | 1 | — |
| Basic | $4/mo | 5 | 5 | — |
| Pro | $9/mo | 10 | 5 | Yes |
| Team | $29/mo | 50 | 20 | Yes |
Each additional tunnel domain counts toward your plan limit. Path-based multi-port routing uses only one tunnel slot. Compare plans →
Everything you need for secure tunnels
Custom Subdomains
Pick a memorable name like my-workspace.mr-coder.io. DNS is configured automatically in seconds — no CNAME records to manage.
Additional Tunnel Domains
Expose extra services on separate subdomains. Dev server on port 3000, API on 8080, database UI on 8081 — each gets its own URL.
Multi-Port Routing
Route different URL paths to different local ports on a single subdomain. /api → 8080, /db → 8081. Uses one tunnel slot.
Auto-Expire Tunnels
Temporary tunnels that clean themselves up. Set 1-hour, 24-hour, or 7-day expiry for demos, pair programming, or sprint testing.
End-to-End Encryption
Every connection flows through our encrypted edge network. Zero-trust architecture — no open ports, no exposed services.
Sub-50ms Latency
Our 300+ edge data centers route traffic through the nearest PoP. Your tunnel feels local from anywhere in the world.
Plan-Based Limits
Basic: 5 tunnels. Pro: 5 tunnels + custom subdomains. Team: 20 tunnels + team prefix. Upgrade or downgrade anytime.
Dashboard Management
Create, start, stop, and delete tunnels from VS Code or the web dashboard. Monitor connection status and uptime in real time.
