Mailpit alternative

A Mailpit alternative with a native desktop interface

Mailpit is a solid open-source mail catcher, but it lives in a browser tab and requires a running binary or Docker container. LocalMail.dev is a native desktop application that starts automatically, persists emails across restarts, and includes responsive previews and dark mode testing that Mailpit does not offer.

Where LocalMail.dev goes further than Mailpit

Responsive email previews

Mailpit renders emails in a browser with no viewport switching. LocalMail.dev lets you instantly toggle between desktop, tablet, and mobile views to check rendering across screen sizes.

Dark mode testing

Mailpit has no dark mode rendering. LocalMail.dev includes a one-click dark mode toggle per viewport, so you can catch broken styles before emails reach subscribers.

Starred emails and collections

Mailpit has no way to organise or bookmark emails. LocalMail.dev lets you star important test cases and group emails into named collections for comparison across sessions.

Native OS notifications

Mailpit has no desktop notification support. LocalMail.dev fires a native OS notification the moment a new email arrives, with no browser tab required.

Persistent inbox with search

Mailpit stores emails in memory by default and loses them on restart. LocalMail.dev persists every email in a local database with full-text search across subject, sender, and body.

Native app, no browser tab needed

Mailpit is accessed via a browser on localhost:8025. LocalMail.dev is a native application with a proper GUI, system tray icon, and launch-at-login support.

Questions about switching from Mailpit

Is LocalMail.dev a drop-in replacement for Mailpit?

Yes. LocalMail.dev listens on localhost:1025 by default, the same default SMTP port as Mailpit. Update your SMTP host to localhost and port to 1025 and LocalMail.dev will intercept everything Mailpit used to.

Does LocalMail.dev work inside Docker or Laravel Sail?

Yes. LocalMail.dev runs on the host machine and Docker containers can connect to it via the host gateway. On macOS and Windows, use host.docker.internal as the SMTP host. On Linux, use the Docker bridge IP address.

Why would I pay $24 when Mailpit is free?

Mailpit is free and a good tool. LocalMail.dev is a commercial product that offers a polished native GUI, dark mode testing, responsive viewport previews, persistent inbox history, and dedicated support. Whether those features are worth $24 once depends on how much time you spend testing emails.

What operating systems does LocalMail.dev support?

LocalMail.dev supports macOS (Intel and Apple Silicon), Windows 10 and 11, and Linux. One licence covers up to three personal machines.
