Pumble

Pumble is a team communication and chat app that offers a generous free plan — including unlimited message history — making it a popular Slack alternative for teams that want capable communication without the cost. Built by Cake.com (the makers of Clockify), Pumble provides organized channels, direct messages, and voice and video calls in a clean, familiar interface, with a free tier that's unusually generous compared to competitors that limit message history or features on their free plans.

Functionally, Pumble covers what teams expect from modern chat: public and private channels to organize conversations by topic or team, direct and group messages, file sharing, threads, search, and voice and video calling for quick discussions. Its biggest selling point is that its free plan keeps unlimited message history — meaning you won't lose access to older conversations as you would on some rivals' free tiers — along with unlimited users, which makes it especially attractive to small businesses, startups and teams watching their budget. Paid plans add advanced features for those who need them.

Pumble appeals strongly to cost-conscious teams that want reliable, organized communication without paying premium prices, as well as to those who simply prefer its straightforward, no-nonsense approach. Because it covers the core communication needs well and gives so much away for free, it's an easy choice for teams looking to centralize their messaging affordably. It fits naturally alongside other Cake.com tools like Clockify and Plaky for teams wanting a low-cost productivity stack. As businesses seek capable communication tools that don't strain their budgets, generous free alternatives are increasingly popular. For teams that want a free, full-featured team chat app with unlimited history and a clean experience, Pumble offers a generous, practical and genuinely useful solution.
