Local email sandbox + catcher for individual developers
Runs on your laptop, catches every email your app sends, and gives you a web sandbox to browse, search, and inspect them in. One self-contained binary.
Point any app at SMTP 127.0.0.1:3535. Open http://127.0.0.1:3550 to search and inspect HTML, text, raw source, headers, and attachments. The same port serves a REST API - existing clients only need a host override. Includes HTML email-client compatibility checks, categories, release to production SMTP, and outbound webhooks.
Not a team tool: no accounts, no auth, no shared sandboxes. SQLite only. Localhost only. Complements hosted Mailtrap; it is not a Sandbox replacement.
