We had been using Slack since 2016, and used it both for ourselves, and with some network partners we work with. Inviting in (government) clients we never did, because we couldn’t guarantee the location of the data shared. At some point we passed the free tier’s limits, meaning we’d have to upgrade to a paid plan to have access to our full history of messages.
Rocket.chat is an open source alternative that is offered as a service, but also can be self-hosted. We opted for a Rocket.chat specific package with OwnCube. It’s an Austrian company, but our Rocket.chat instance is hosted in the Netherlands.
Slack offers a very well working export function for all your data. Rocket.chat can easily import Slack archives, including user accounts, channels and everything else.
With the move complete, we now have full control over our own data and access to our entire history. The cost of hosting (11.50 / month) is less than Slack would already charge for 2 users when paid annually (12.50 / month). The difference being we have 14 users. That works out as over 85% costs saving. Adding users, such as clients during a project, doesn’t mean higher costs now either, while it will always be a better deal than Slack as long as there’s more than 1 person in the company.
We did keep the name ‘slack’ as the subdomain on which our self-hosted instance resides, to ease the transition somewhat. All of us switched to the Rocket.chat desktop and mobile apps (Elmine from Storymines helping with navigating the installs and activating the accounts for those who wanted some assistance).
Visually, and in terms of
user experience human experience, it’s much the same as Slack. The only exception being the creation of bots, which requires some server side wrangling I haven’t looked into yet.
The move to Rocket.chat is part of a path to more company-wide information hygiene (e.g. we now make sure all of us use decent password managers with the data hosted on EU servers, and the next step is running our own cloud e.g. for collaborative editing with clients and partners), and more information security.
