Pumble, from the makers of Clockify, is one of the most generous free team chat tools available, offering unlimited users and unlimited searchable message history at no cost, with affordable paid tiers that add video, screen sharing, and admin controls. Starting around $2.49 per user a month, it is a natural pick for cost-sensitive teams.
Where Pumble shows its youth is ecosystem depth: it has fewer native integrations than Slack, a smaller app marketplace, and video only on paid tiers. Teams that need heavy integrations, self-hosting, or a more mature platform may want one of the alternatives below.
TL;DR
| Tool | Starting price | Rating | Best for |
|---|---|---|---|
| Slack | $7.25/mo | ★ 4.7 | Teams that depend on a wide stack of integrated SaaS tools. |
| Microsoft Teams | $4/mo | ★ 4.5 | Companies standardized on Microsoft 365. |
| Zoho Cliq | $3/mo | ★ 4.6 | Teams already using the Zoho suite. |
| Flock | $4.5/mo | ★ 4.5 | Small teams that want lightweight to-dos and polls inside chat. |
| Mattermost | $10/mo | ★ 4.4 | Technical and regulated teams needing on-prem chat. |
| Rocket.Chat | $8/mo | ★ 4.3 | Organizations needing customer messaging plus internal chat on their own servers. |
Best for integration-heavy software teams
What it does better than Pumble
Slack has the largest app directory in team chat, mature Workflow Builder automation, polished huddles, and best-in-class search, giving far more ecosystem depth than Pumble.
Where Pumble still wins
Slack is much more expensive and its free plan caps message history at 90 days, where Pumble's free history is unlimited.
Best for: Teams that depend on a wide stack of integrated SaaS tools.
Best for Microsoft 365 organizations
What it does better than Pumble
Teams is bundled with Microsoft 365, handles large meetings and calling far better than Pumble, and integrates natively with Office documents and Outlook.
Where Pumble still wins
Teams is heavier and more complex, and only cost-effective if you already pay for Microsoft 365.
Best for: Companies standardized on Microsoft 365.
Best for existing Zoho customers
What it does better than Pumble
Zoho Cliq adds native integration with a full CRM and office suite that Pumble lacks, plus bots and PrimeTime broadcasts, at a similar low price.
Where Pumble still wins
Cliq's free tier is less generous than Pumble's, and its interface feels more dated.
Best for: Teams already using the Zoho suite.
Best for chat with built-in productivity extras
What it does better than Pumble
Flock bundles built-in to-dos, polls, reminders, and shared notes out of the box, giving more native productivity extras than Pumble's chat-first approach.
Where Pumble still wins
Flock's free tier is less generous than Pumble's unlimited history, its base price is higher, and its development pace has slowed.
Best for: Small teams that want lightweight to-dos and polls inside chat.
Best for self-hosted data control
What it does better than Pumble
Mattermost is open-source and self-hostable for complete data ownership, with strong DevOps and security tooling Pumble cannot offer.
Where Pumble still wins
It requires infrastructure to deploy and maintain, and lacks Pumble's instant free cloud simplicity.
Best for: Technical and regulated teams needing on-prem chat.
Best for data-sovereignty requirements
What it does better than Pumble
Rocket.Chat is open-source with full data ownership and adds omnichannel customer messaging, a broader platform than Pumble for regulated organizations.
Where Pumble still wins
Its self-hosted administration is more complex, and its consumer polish trails Pumble's clean interface.
Best for: Organizations needing customer messaging plus internal chat on their own servers.
