Developer Tools

Mail, webhooks, and tunnels for localhost

About

Portlight consolidates email capture, webhook testing, and localhost exposure for developers into a unified desktop application. It launches with a single click. The local SMTP server intercepts all outgoing emails from your application. A webhook listener displays each payload and allows instant replay. HTTPS tunnels provide a public URL for your localhost environment. Forget terminal commands, excessive browser tabs, and configuration files.
