About
Portlight is a local development toolkit that combines three common needs into a single desktop app: email capture, webhook inspection, and localhost tunneling. It runs a local SMTP server to catch outbound emails from your app so you can preview the HTML, review headers, and open links without sending messages to a real inbox. It also provides a webhook listener that records incoming requests, showing payloads and headers and allowing you to replay events to re-trigger your handler. For sharing and external integrations, Portlight creates HTTPS public URLs for a local server so teammates can access a running app, you can test on mobile, or third-party services can deliver webhooks to your machine. The site also notes planned features like Windows support, projects, a menu bar app, and shareable webhooks.
