Short answer: Slack alternatives and who runs the server. Put the current file, the decision and the next owner in one channel. Basic is 9 USD per paid account a month, or 86 USD a year, with 25 GiB. The trial is 3 days. The iPhone and iPad app is coming soon. The encryption scope is on the security page.
Compare who runs the server and what is encrypted. BusyVault uses Aegis-128L. Mattermost and Rocket.Chat can run on your server. No score.
Security on a chat shortlist is not a star rating. Ask who runs the server, who can open a stored message, and what a backup contains. BusyVault is a hosted service. Mattermost and Rocket.Chat are the names on this site when the team wants to run the server itself. Confirm each vendor's current edition before you treat a marketing line as a control.
What BusyVault encrypts
BusyVault encrypts messages, voice notes, files sent in conversations, tickets, tasks, checklists, notes and scheduled messages with Aegis-128L before storage. The hosted service decrypts them to run chat, search, previews and notifications. Files opened through a public share link are not protected that way, so someone without an account can open them. A self-managed Mattermost or Rocket.Chat deploy moves the server into your own operation. That is a different job, not a laboratory win for either side. Slack alternatives
BusyVault, Mattermost and Rocket.Chat
BusyVault encrypts messages, voice notes, files sent in conversations, tickets, tasks, checklists, notes and scheduled messages with Aegis-128L before storage. The hosted service decrypts them to run chat, search, previews and notifications. Files opened through a public share link are not protected that way, so someone without an account can open them. The public app is hosted. Enterprise self-hosting runs on your servers under a separate contract, so the operating work moves to your team. Mattermost and Rocket.Chat are the names on this site when you want to run a chat server yourself from the start. Confirm each current edition. This page does not award a score, a laboratory winner or a star rating. Read the Slack alternatives list for the wider ten, then come back here only for the question of who runs the server.
What to write down before a pilot
Write who runs the server, what is encrypted, and what a restore returns. For the hosted BusyVault app, message content and files are encrypted with Aegis-128L before storage. For Enterprise self-hosting, your team runs the servers under a separate contract and takes on patches and backups. Mattermost and Rocket.Chat are the comparison when self-managing is the requirement from day one. Confirm their current editions on their own sites. Do not convert any of those facts into a star rating or a claim that a lab picked a winner. Use one project as the test: sign in, upload a file, search for the decision, and open a backup. The wider list of ten tools is on the Slack alternatives page.
What to write down before you switch
Read “Slack alternatives and who runs the server” as a buying note for one job, not as a score. Name the file you would actually send, the history you still need to search, and who pays for each account. BusyVault is the hosted app for that job. Other products stay on this page only where the comparison says who runs the server or what one upload allows. There is no star rating and no laboratory winner. Keep the quote you were sent beside any public price printed here.
Files, history and the next owner
On Slack alternatives and who runs the server, keep the file next to the sentence that approved it. Slack documents a 1 GB cap on one upload and, on the Free plan, 90 days of visible history. Those two limits are the public facts this site already cites.
BusyVault bills storage per paid account: 25 GiB on Basic and 100 GiB on Pro. Extra storage is 0.03 USD per GiB a month after you confirm the charge. Basic is 9 USD a month or 86 USD a year. Pro is 30 USD a month or 288 USD a year. One subscription does not cover the team.
The trial is 3 days and 10 GiB. Use it to upload a real file and to search for a decision, not to announce a company-wide move. If the file does not fit or the old decision cannot be found, say so in the channel before you promise the room is the archive.
Where the app runs
BusyVault runs in the browser and can be installed from Chrome or Edge on Windows, macOS and Linux. The Android app is on Google Play and uses the same account. The iPhone and iPad app is coming soon. Enterprise customers can run BusyVault on their own servers under a separate contract. There is no public installer on this site for that path. This page does not claim SOC 2, ISO 27001 or HIPAA.
A check you can finish this week
For Slack alternatives and who runs the server, finish four lines and stop. Line one is the project name. Line two is the channel name. Line three is where the current file lives. Line four is the next owner. Add one rule for meetings: what must be decided live, and what must be written down the same day.
Ask someone who was not on the call to find the file without help. If they open the right channel first, the structure works. If they search three threads and still ask which version is current, move the file to the channel and leave a pointer. Owners and administrators can export a BusyVault backup from workspace or channel settings. After a restore, check the text, the file references and who can open them. Keep the original files until that check passes. Product questions go to the address on the support page.
