12M+ users in over 150 countries trust Rocket.Chat

Admins love Rocket.Chat and the employees rave about it!

First, we’d like to give a quick nod to the team at Slack. Undeniably, they’ve also built a great product that people love to use.

So why do companies choose [.c-red]Rocket.Chat over Slack?[.c-red]

In short, because if you handle sensitive business or customer data, Slack either becomes very expensive or can't adhere to your security and compliance requirements at all. Rocket.Chat customers believe compromised data protection is a disqualifying factor. These tend to be organizations in highly regulated industries such as healthcare, government, public sector, financial services,  education, etc.

Here are the 6 reasons why companies choose Rocket.Chat over Slack

Numerous deployment options that Slack can’t offer

Slack is a SaaS-only solution. For companies that focus on data privacy, security, and ownership, that’s just not an option. On-prem, self-managed or air-gapped deployment, the choice is yours with Rocket.Chat.

Get more flexibility and control in every conversation

Unlike Slack, you can actually see what’s going on under the hood. This means additional security assurances, unlimited customizations, and the ability to see and contribute to the roadmap. If you are looking for an open source alternative to Slack, Rocket.Chat is built for you!

Decentralized and federated communications

Slack lets you message people in other companies, such as vendors, partners and suppliers - as long as they are also using Slack. Using Federation, Rocket.Chat lets you connect across platforms - so you don’t ever have to ask: Are you on Slack?

Security-centric features available with every plan

E2E encryption, chat history, HIPAA-ready software, role-based access - All the things you need if you care about the privacy and security of your data come with a high barrier to entry with Slack (or don’t exist at all).

Unlimited conversation history for everyone

No matter which Rocket.Chat plan you have, everyone gets access to the full conversation history, no matter when they joined a certain channel. With Slack, on the other hand, you don’t always get access to crucial conversations that happened in the past. 

Cost-effective alternative to Slack

Rocket.Chat is not only more affordable, but organizations that have deployed it have reported over 33% in cloud savings while experiencing faster and more secure communication.
