The Best Team Chat Apps in 2026
Two of these are already in the suite you pay for. The others charge per seat for chat alone.
Microsoft Teams is the cheapest dedicated seat at $4 per user per month on Essentials, and it is already paid for if you run Microsoft 365 Business Basic at $7. Google Chat is the same story on Workspace, from $7 per user. Slack is the one you pay for when chat is the product: Pro is $7.25 per user per month billed annually. Zulip undercuts that at $6.67 on Cloud Standard, or $0 if you self-host. Discord is free for community servers and is not a company chat plan.
Most companies are not choosing a chat app. They are deciding whether to pay again for something their office suite already includes. Teams lives inside Microsoft 365. Chat lives inside Google Workspace. Slack sells the same job as a standalone product, and the bill is only chat.
That is the comparison that matters.
Feature lists converged years ago: channels, threads, huddles, search, apps. The difference is whether the seat is incremental or already on an invoice you cannot cancel.

What it is
A team chat app is the persistent text layer of work: channels, direct messages, files, search, and a growing pile of bots. Voice and video sit on top. The category now splits into three shapes. Suite chat is bundled with email and files.
Dedicated chat is a product you buy for itself. Open-source chat is software you host, with a commercial cloud as an option.
Pricing follows the shape. Suite vendors hide chat in a per-user bundle.
Dedicated vendors charge per seat and gate history. Open-source vendors charge only if you want them to run it.
Why it matters
Message history is where the real cost sits, and it is the number Slack puts in the smallest type. The Free plan keeps 90 days. After that, the conversation that explained a decision is gone unless someone exported it.
Teams Essentials and Workspace do not run that clock the same way, because chat is not the thing they are selling.
The second cost is double-paying. A company on Microsoft 365 that also buys Slack Pro is paying twice for channels. That can be the right call. It is rarely the accidental one people think they made.
Key features to look for
The bottom line
If you already pay for Microsoft 365 or Google Workspace, start there. Teams Essentials at $4 is the fallback if you want Microsoft chat without the rest of Office.
Pay for Slack when chat is the system of record and the suite client is the thing people avoid; Pro at $7.25 per user per month is the real product, not the 90-day Free plan.
Zulip is the better dedicated buy when you want topics and a lower seat price, or when you want to host it.
Discord is for communities. It is not a replacement for any of the others the day you have employees, customers or a lawyer.
