How we grade them
| 3.0GPABrosixVery good | 3.6GPAFlockExcellent | |
|---|---|---|
| Value for money | BEssentials 20 is a flat $40 a month for up to 20 users, billed yearly. Fill all 20 seats and that's $2 a head, which is a bargain. With five of you it's $8 each, a bit over the $7 team chat typically starts at. Ultimate is $6 a user, with 2FA and user permissions. | APro is $4.50 a user a month billed annually, or $6 monthly. That's clearly under the going rate for team chat, and it gets you unlimited searchable messages and channels, 10 GB per member and group video calls. |
| Free plan and trial | CNo free plan. Every plan starts with a 14-day free trial, and you don't need a credit card for it. After that you pay or you stop. | BStarter is free for teams of 1 to 20, with unlimited messages. But only 10,000 of them are searchable, you get 10 public channels and 5 GB for the whole team, and video calls are 1-1 only. Tight for a busy team. |
| Features | BOne-to-one and group chat with read receipts and mentions, chat rooms, voice and video calls, screen sharing with remote desktop control, and file transfer of any size. Solid basics. But the whiteboard, broadcast messages and peer-to-peer transfer are only in the older Windows Classic app. | APublic and private channels, direct messages, voice notes, and video calls with screen sharing. Then shared to-dos with due dates, notes, anonymous polls and reminders, all in the app. Group video does stop at 20 participants. |
| Ease of use | BNo App Store rating on record, so a B is as high as we go. An admin adds the users from a web control panel and that's the network made. It's pitched at teams without dedicated IT staff who want chat set up in minutes. | BNo App Store rating is on record, so a B is as high as we go. It's an app you install and start chatting in, and the All Channel feed gathers new messages in one place. |
| Platforms and integrations | AWeb, Mac, Windows, Linux, iPhone and Android. It connects to other tools through Zapier, Make, Pipedream and Integrately, and Ultimate adds Active Directory integration. Just note that a few features only live in the Windows Classic app. | AWeb, Mac, Windows, Linux, iPhone and Android. The app store connects Google Drive, Asana, Trello, Jira, GitHub, Zoom and Zapier, and there are webhooks and developer docs for building your own apps. |
| Best for | a closed, admin-controlled chat network for an office | low-cost team chat with to-dos and polls built in |
