Download Rocket.Chat 4.18.5 for Windows

Rocket.Chat is the leading open source team chat software solution. Free, unlimited and completely customizable with on-premises and SaaS cloud hosting.

Rocket.Chat is an open-source team communication platform that provides messaging, file sharing, video conferencing, and collaboration tools. It is developed in TypeScript and built on Node.js and MongoDB. The software is available as both self-hosted and cloud-based deployments.

Rocket.Chat was created in 2015 by Gabriel Engel and collaborators in Porto Alegre, Brazil. The project began as part of work on a customer relationship management (CRM) system when the developers needed a live chat component. According to Gabriel Engel, the team, originally working at the Brazilian business software company Konecty, had explored integrating Slack but found it too limited for their needs and decided to build their own chat platform using JavaScript. A prototype was published on GitHub, after which the project attracted community interest and further development.
