Open source webmail client alternatives for GMail

Gmail logo

A while ago there were many alternatives for email services that existed, I still remember that one of the biggest differences from one to another was the ability they had to attach larger or smaller files. Now that has gone into the background, many of those services no longer exist and others continue to remain as Yahoo, GMail and Hotmail. One of the most used and successful of all has been Google's mail service, GMail, of which we are going to introduce some good open source alternatives in this article.

Emails along with instant messaging systems are the order of the day. Perhaps in certain areas the apps of instant messaging like Telegram or Whatsapp have been gradually displacing the email services to be more direct, but they are still very important and will continue to be for many years. But the GMail client is not the only one that exists far from it, there are many others and we are going to list just some of the best alternative open source webmail clients:

  • Roundcube: it is a modern webmail client that can be easily installed on a LAMP server (Linux, Apache, MySQL, PHP).
  • Zimbra: we have already talked about this client, with which to implement a web-based mail server and client. Its license, like the previous one, is of the GPL type, and it is a highly recommended option.
  • Squirrel Mail: is the one that I use particularly, this client is modern and has a fairly simple web interface from which to manage it. It is written in PHP and is distributed under the GPL license.
  • rainloop: extremely modern, with an interface to improve the experience if you are used to using other commercial interfaces like GMail's own. It is available under AGPL and you can browse project information on GitHub.
  • mailspring- a fairly young and new project with interesting options to support various accounts, translation, etc. It was developed by one of the creators of Nylas Mail ...

There are more, but these are the most prominent ...

    Hello everyone, I have some licenses for life, licenses from before 2012, they are limited and I have 10, 50 and 100 users, they are licenses that I transfer from my domain to yours, you can see more in

    If the domain uses Webmail or a service other than GSuite it is configured in a few hours, if you use GSuite it is necessary to delete the account and configure the new license and it may take about 2 or 3 days
