Lorem Ipsum

They’ve also built a great product and share the same open source philosophy as us. If you’re here to evaluate Rocket.Chat vs Mattermost, you’re already on the right track to find a platform that will help enable real-time conversations across your business while keeping your data fully protected.

So what’s the [.c-red]difference between Rocket.Chat and Mattermost?[.c-red] How do I pick?

We’ll compare features, capabilities and all of that (important) stuff further down this page, but the biggest difference is our DNA.

The founding team at Mattermost built a platform specifically focused on helping developers by making DevOps real-time while the team at Rocket.Chat is focused on building software to enable every conversation to happen in real-time; between colleagues, with other companies, with your customers and also with the apps you love.

Here are 4 reasons why companies pick Rocket.Chat over Mattermost

Rocket.Chat community version includes basic LDAP directory sync

Every LDAP feature, such as basic directory sync, SAML, Oauth or advanced LDAP functionalities are paid with Mattermost. The community version doesn’t include any of it. With Rocket.Chat, basic directory sync is included in the community license. If that’s all you need, you’re free to use it as you please and if you need more advanced LDAP functionalities you can test and see your users flowing in before making a commercial commitment. That’s faster time to value.

Rocket.Chat offers a truly permissive open source license

Rocket.Chat’s community edition is licensed under the most well-understood and permissive open source license – the MIT source license. Mattermost offers a more restrictive MIT-COMPILED-LICENSE which pushes anyone depending on enhancing or modifying their source code into agreements such as AGPL V3.

AGPL V3, one of the more restrictive open source licenses known, enforces all modified code to be made open source. Any enhancements made by large enterprise customers, for example, can be forced to be made open source and shown to everyone – including your competitors.

Rocket.Chat is backed by a larger developer community

Not an opinion, just the numbers. Rocket.Chat has over 30,000 stars on Github while Mattermost just over 20,000. That means Rocket.Chat has about 10,000 more developers helping improve the source code every day.
