What’s the difference between Slack and Pumble?

Unlimited message history

Slack lets you see last 10,000 messages. If you have important info in some old messages, you’ll have to pay to access it.

Pumble lets you see ALL the messages ever sent, for free. You can search your team’s conversation history and find an important message no matter how long ago it happened.

The FREE plan in Pumble

Let’s say a team of ten people exchanges 50 messages a day per member (a conservative estimate). If using Slack, the team would burn through the 10,000 message limit in 20 workdays, making all prior messages and shared files inaccessible. This limitation would require the team to store all relevant information and files elsewhere, or risk losing them forever. With Pumble, there is no such worry.

2x more storage space

Slack gives you 5GB, meaning you’ll have to delete important files very often.

Pumble gives you twice that, 10GB, so you can keep and access more files.

Slack alternative - storage
No limitations

The free plan also imposes no limitations to channels, group conversations, threads, or notification options, allowing teams to structure and carry the communication in an organized manner. It also doubles the available storage provided by Slack — 10GB storage per workspace.

Keep data on private server

Maximum data security

Organizations can control where and how data is stored, protecting it from loss, leaks, and misuse.

Maximum data privacy

Organizations can safely store confidential information, control access, and trace usage in order to comply with various regulations.

Data protection

The ongoing global shift to remote work has placed an even greater strain on organizations to secure their data and control who can access it. While all communication in Pumble is encrypted by default, we also provide the ultimate degree of protection and privacy for organizations that require it — Pumble Server.

Self-hosting allows organizations to fully configure their Pumble experience with as many dedicated workspaces as they need and no storage limitations.

Why teams switch from Slack to Pumble

“My small nonprofit has been on the search for a team communication software that doesn't break the bank. Slack is great, but unfortunately, the free version wasn't cutting it for us.
Luckily, we stumbled across Pumble, and it's perfect! It does everything Slack does, but for free! It's very similar to Slack in terms of functionality. Very easy to use. The interface is great. You can have multiple workspaces as well.”

”Easy to use, simple and clean layout. Using the software is not really complicated and it does not have a steep learning curve. I also like that you can download the app. Good alternative for Slack or Teams if you don't need all the bells and whistles, just a basic chat platform. Another thing that I will look into is to host Pumble on my own server”

”Pumble is pretty much like Slack but tons of free features. I've been using Slack with my clients for many years and I wanted to implement something similar for my own team. But Slack free, does not let you add more than 5 team members, I didn't see such a limit in Pumble though. It's very easy to get start with, very easy to manage. Login and Operation is very easy.”

“One of the main reasons we switched to Pumble from Slack was the fact that Slack was too expensive for us and the free version of it didn't keep the history of messages.
Pumble has a free chat history feature included from the start which is very important for us. Another feature that we like a lot is the channels. It's pretty much the same as in Slack (and that was the reason we switched to Slack from Skype, that had the history, but we didn't really like the group's part. The messages and channels structure feels a lot more natural in Slack/Pumble than in Skype.)
The Slack plan that we had didn't have the feature of keeping the history of our chats, which might be not critical for some departments (such as marketing), but for projects' discussion, it's important to see what has been discussed previously to have paper track.”

“Overall, I find Pumble very easy to use. Same as much as Slack. In fact, we migrated everything from Slack to Pumble now. I do not worry about messages being deleted anymore.
It doesn't have a limit on message and files history compared to Slack. This is what matter's most to me as I really would love to review messages from time to time to check message threads.”
