Introducing Localport: tunneling you can actually inspect

We built Localport because localhost tunneling should be flexible, transparent, and work behind any network. Here is what ships in v1 and why it matters.

announcement

Today we're releasing Localport, a tunneling platform that gives your local services a public URL with a transparent agent you can read on GitHub.

Why we built this

We've used tunneling tools for years. They all share the same limitations. HTTP only on the free tier. Per seat pricing that punishes growing teams. Closed binaries that sit between your machine and the internet. And no support for the things we actually needed, like addressing individual devices in a fleet or sharing one webhook across a team.

We wanted something that:

  • Supports HTTP, TCP, TLS, and mTLS tunnels on every plan
  • Charges a flat price per team, not per user
  • Lets teams share webhooks without hacky workarounds
  • Gives IoT fleets one URL per device
  • Ships an agent you can read on GitHub before it touches your network

So we built it.

What Localport does

For web developers. One command to share your local app. You get an HTTPS URL with a real certificate every browser trusts. Works with React, Next.js, Django, Rails, Flask, anything. 
localport http 3000 --token YOUR_TOKEN
# → https://abc123.tunnel.localport.dev
For backend developers. TCP tunnels for databases, SSH, and custom protocols. Your Postgres on localhost:5432 gets a public address on every plan, not behind a paywall. 
localport tcp 5432 --token YOUR_TOKEN
# → tcp://abc123.tunnel.localport.dev:47266
For teams. Shared tunnels that broadcast webhooks to every connected teammate. When Stripe sends a webhook, everyone on the team sees the full payload at the same time. For IoT and homelabs. Mesh tunnels where each device gets its own URL. No VPN, no port forwarding, no static IPs. One token, twenty devices, each individually addressable.

The agent is on GitHub

The Localport agent is a single Go binary with zero runtime dependencies. Its source lives on GitHub. You can read every line, build it from scratch, and audit the tunnel protocol.

We believe the tool that sits between your machine and the internet should be transparent. You should be able to see exactly what it does with your traffic before you ever run it.

What we ship

The agent source is public for review. The hosted infrastructure (edge servers, API, dashboard) is a managed service. Licensing is finalised before a public release.

What you get

Every plan includes:

  • HTTP, TCP, TLS, and mTLS protocols
  • Automatic HTTPS with real certificates
  • Web dashboard for live monitoring
  • Mesh tunnels for device fleets
  • Shared tunnels for team webhooks

No surprise overages. No per user fees. Flat team pricing from $5/mo.

What's next

We're working on custom domains, advanced IP allow lists, and richer dashboard analytics. If you have ideas or run into issues, open an issue on GitHub or join our Discord.
