Portlight – Integrated mail, webhook, and localhost tunneling tool

Summary: Portlight combines local SMTP email capture, webhook listening with payload replay, and HTTPS tunneling for localhost into one desktop app, eliminating the need for multiple tools or command-line setup.

What it does

It captures all emails sent by your app via a local SMTP server, displays webhook payloads with replay capability, and provides HTTPS tunnels to expose localhost with a public URL.

Who it's for

Developers who need to test emails, webhooks, and expose localhost without managing separate tools or configurations.

Why it matters

It streamlines development workflows by consolidating email testing, webhook inspection, and tunneling into a single app without terminal commands or config files.
