Override port on the fly

expose tunnel -p 8080           # LocalTunnel on port 8080
expose tunnel -P cloudflare     # Use Cloudflare instead
expose tunnel --server host:7890 -p 3000  # Self-hosted

Why Expose?

🌐

3 Providers, 1 Tool

LocalTunnel for quick tests, Cloudflare for reliability, or your own server for full control.

🏠

Self-Hosted Mode

Run expose server on any $5 VPS. Your traffic, your rules — no third-party inspection.

⚡

Zero Friction

No accounts, no API keys, no dashboards. Just install and run — three commands from zero to tunnel.

📦

Single Binary

One file under 10MB, statically compiled. Copy it anywhere, it just works. No runtime needed.

🔧

Developer First

Project-based config files, short flags, clean output, and >80% test coverage. Built by devs for devs.

🔓

Fully Open Source

MIT licensed. Audit the code, extend it, run it yourself. No proprietary lock-in.

Self-hosted advantage

With self-hosted mode, traffic stays entirely on your infrastructure — no rate limits, no third-party routing, no terms-of-service surprises.
