Maildrop alternative

A Maildrop alternative built for developers who test outgoing email

Maildrop is a disposable inbox service for receiving emails from the internet. If what you actually need is to test the emails your own application sends, LocalMail.dev is the right tool. It runs a real SMTP server locally, intercepts every outgoing email from your app, and lets you preview and inspect it before any email reaches a real inbox.

No cloud inbox. No shared addresses. Nothing leaves your machine.

One-time purchase. 14-day refund policy. macOS, Windows, and Linux.

Maildrop vs LocalMail.dev

Maildrop is a public disposable inbox. LocalMail.dev is a private local SMTP server. They solve different problems.

Maildrop

Disposable cloud inbox for receiving external emails

Maildrop gives you a public email address at maildrop.cc that anyone can send to. It is useful for signing up to services without using your real address. It is not designed for testing the emails your own app sends.

  • No SMTP server you can point your app at
  • Emails are public and stored in the cloud
  • No rendered previews or header inspection
  • Inbox is public and can be read by anyone
LocalMail.dev

Local SMTP server for testing emails your app sends

LocalMail.dev intercepts outgoing emails from your own application before they reach the internet. It is purpose-built for development: responsive previews, dark mode testing, raw header inspection, and a persistent local inbox.

  • Real SMTP server on localhost:1025
  • All data stays on your machine, fully private
  • Responsive previews, dark mode, raw headers
  • Fully offline after one-time $24 purchase

Why developers use LocalMail.dev instead of Maildrop

Test your app emails, not someone else's

Maildrop is designed for receiving emails sent to a public address. LocalMail.dev is designed for intercepting emails sent by your own application. If you want to verify that your password reset email, welcome email, or invoice notification looks correct before shipping, LocalMail.dev is the right tool.

Your test data never leaves your machine

Maildrop stores all emails on its servers and those inboxes are publicly accessible by anyone who knows the address. LocalMail.dev stores every captured email in a local database on your machine. No email content, headers, or metadata is sent to any external server.

See exactly how your emails render

Maildrop shows raw email text with no rendering tools. LocalMail.dev gives you responsive desktop, tablet, and mobile previews plus a dark mode toggle, so you can verify your email templates across all four combinations before a single email reaches a subscriber.

Works without an internet connection

LocalMail.dev runs a real SMTP server on localhost. Your development workflow continues uninterrupted regardless of network availability. Once your licence is activated there is no cloud dependency at all.

# Point your app at LocalMail.dev instead of the internet
# No SMTP server to configure with Maildrop
# Emails sent externally and stored in cloud
MAIL_MAILER=smtp
MAIL_HOST=localhost
MAIL_PORT=1025
MAIL_ENCRYPTION=null

Works with Laravel, Django, Rails, Node.js, and any SMTP client.

Questions about switching from Maildrop

Is LocalMail.dev really a Maildrop alternative?

They solve different problems. Maildrop is a disposable cloud inbox for receiving emails from the internet at a public address. LocalMail.dev is a local SMTP server for intercepting emails your own application sends during development. If you are looking for a tool to test transactional email output, LocalMail.dev is the correct comparison. If you need a throwaway inbox for receiving external emails, the use cases do not overlap.

Can I use LocalMail.dev to intercept emails from any framework?

Yes. LocalMail.dev works with any framework or language that supports standard SMTP, including Laravel, Django, Ruby on Rails, Node.js, Next.js, Symfony, Spring Boot, and more. Set your SMTP host to localhost and port to 1025. No authentication credentials are required by default.

How private is LocalMail.dev compared to Maildrop?

Maildrop inboxes are public. Any email sent to a Maildrop address can be read by anyone who navigates to that address. LocalMail.dev stores all captured emails in a local database on your own machine. Nothing is uploaded to any server. Only you can access your local inbox.

Does LocalMail.dev require an account?

You need an account to complete the purchase. After that, no login or internet connection is required. The app runs entirely locally with your licence key stored on your machine.
