Rocket.Chat and SlackVault
There's no migration here. Rocket.Chat is a chat your team would move to and run; SlackVault keeps the team on Slack and copies its messages into your Firebase project. SlackVault has no import from Rocket.Chat.
Where to start
If the team is staying on Slack: Slack app setup, then Firebase setup, then the browser extension. The first sync is covered in Syncing & your archive.
Last checked November 7, 2026. Check Rocket.Chat for yourself. SlackVault is not affiliated with or endorsed by Slack.
Which one suits you
Choose Rocket.Chat if you want an open-source chat you host yourself, with retention policies and exports built in and a free edition to start on.
Choose SlackVault if moving the team off Slack is not on the table and the only thing missing is a lasting copy of what was said and shared.

What SlackVault does not do
- Messages, channels, members and file records go to your own Firebase project. Supabase is not supported yet.
- Files do not go to your Google Drive or your Firebase project. When file copying is switched on in our extension build, each file uploads to our file storage with its visibility set to public: the link is hard to guess, but anyone holding it can open the file without signing in. Where no storage key is set in the build, no copy is made, and your archive keeps the file’s details and Slack’s link, which works only while Slack serves that file.
- There is no way yet to send records back into Slack.
- The sync runs in a browser extension, every 15 minutes, only while that browser is running.
- SlackVault can copy only what Slack’s API still returns, so anything older than your plan’s window is out of reach unless an earlier sync already saved it.
- If saving one thread fails, the sync logs it and moves on without retrying those replies.
- Search checks the most recent page of messages, up to 50 per query, not the whole archive.
- The extension and the Android app have no store listing yet, and the source code is in a private repository.
