Free Slack alternatives for a small team
Short answer: Free Slack alternatives for a small team. 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.
Free Slack alternatives with a real free tier: Discord, Element, Pumble, Zulip, Mattermost, Rocket.Chat. BusyVault's 3-day trial is not free.
Short answer. A free Slack alternative is a tool with a real free tier, not a trial that ends. Discord, Element, Pumble, Zulip, Mattermost and Rocket.Chat are the names teams shortlist. BusyVault is not on that free list. Its free account is a 3-day trial with 10 GiB. After that, Basic is 9 USD per paid account a month.
Free Slack alternatives and the limits to read first
| Tool | Free plan | Check before you move |
|---|---|---|
| Discord | Free for communities. | Whether a client file belongs on a community server. |
| Element | A free client on the public Matrix network. | Who runs the homeserver. |
| Pumble | Pumble publishes a free tier. | The current cap on the vendor pricing page. |
| Zulip | Zulip publishes a free cloud tier and source you can run. | The current organization limit. |
| Mattermost | A self-managed option. | Hosting, backups and the current license. |
| Rocket.Chat | A community edition. | Whether your deploy needs a paid edition. |
BusyVault is a trial, not a free plan
Do not put BusyVault in a list of free Slack replacements. The trial lasts 3 days and includes 10 GiB. Basic then costs 9 USD per paid account a month or 86 USD a year, with 25 GiB. Pro is 30 USD or 288 USD, with 100 GiB. Paying can still be cheaper than a free tool that splits the file and the decision, but that is a workflow question, not a claim that the trial is free forever.

QUESTIONS
Questions about free Slack alternatives
Is Slack itself free?
Slack has a Free plan. It limits visible history. A free plan with a history cap is not the same as a paid workspace.
Why is BusyVault missing from the table?
Because the lasting offer is paid. The 3-day trial is not a free tier. Listing it as free would be false.
Are the free caps listed as numbers?
No. Those caps change, and this page only says which page to open. We do not print a number we have not checked.
What if the free tool cannot hold the file?
Then the free price is not the cost. Look at storage, history and who can still open the file next month.
What to write down before you switch
Read “Free Slack alternatives for a small team” 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 Free Slack alternatives for a small team, 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 Free Slack alternatives for a small team, 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.
Free tier is not a free company
A free Slack alternative still has a cap: history, seats, file size, or the hours you spend running the server. BusyVault’s free account is a 3-day trial with 10 GiB, then Basic at 9 USD a month per paid account. Discord can be free for a community and still be a poor archive for client work. Read the vendor’s current free limits on one real job before you move the team.
