Pumble is the team messaging platform from CAKE.com — the company behind the popular time tracking tool Clockify — that attracted attention by offering unlimited users and unlimited message history for free. In a market where Slack charges per user and limits free-tier history, Pumble’s generous free plan was a clear differentiator at launch in 2020.
The platform covers the standard team chat features: channels, direct messages, threads, file sharing, voice and video calls, and screen sharing. The interface takes obvious inspiration from Slack, which means the learning curve for teams switching over is minimal. Guest access lets organizations bring external collaborators into specific channels.
Pumble’s connection to the CAKE.com suite is a strategic advantage. The company also makes Clockify (time tracking), Plaky (project management), and CAKE.com (HR management), creating an ecosystem of affordable business tools that can work together. For budget-conscious teams already using Clockify, adding Pumble is a natural extension.
The free tier includes unlimited message history, unlimited users, one-on-one voice and video calls, and 10 GB of total file storage. The paid Business plan adds group video calls, screen sharing, guest access, and more storage, while the Enterprise plan includes admin and compliance features.
Pumble’s development has been rapid since launch, adding features like threads, custom emojis, user groups, and improved search. The platform offers native apps for Windows, macOS, Linux, iOS, and Android, plus a web client.
The trade-off compared to Slack or Microsoft Teams is a smaller integration ecosystem and fewer advanced features. Pumble doesn’t have the depth of workflow automation, app marketplace, or enterprise-grade compliance tools that larger platforms offer. But for teams primarily needing a reliable, affordable place to chat, the value proposition is compelling — especially that unlimited free tier that Slack long ago abandoned.
