Slack
Channel-based team messaging with huddles, workflows and AI
Which one is for you
Pick Slack if
- Fits if your team wants conversations sorted by channel instead of email threads
- Works for teams that share channels with outside partners or plug many apps into chat
Look elsewhere if
- Tight if you're staying free, as only 90 days of messages stay searchable and you get 10 apps
- Skip it if you want group huddles or Slack Connect for free, as both are 1:1 until Pro, which has no trial
- Pricey if you need single sign-on, SCIM or AI search, which start at Business+ for $15 a user a month
- Watch out: enterprise search and data loss prevention are on Enterprise+ at $45 a user, bought through sales
- Not for you if you'd run huddles in a browser other than Chrome or Firefox, as they aren't supported there
Pick Voxer if
- Fits if your crew talks rather than types, such as drivers, delivery or hospitality staff
- Works for small teams that want voice messages saved and searchable
Look elsewhere if
- Skip it if you need a desktop app, as it runs on web, iPhone and Android only
- Tight if you stay free: messages are kept for only 30 days
- Pricey if you want AI summaries, voice-to-text and translation, all on Pro + AI at $7.99 billed monthly
- Watch out: Business is for teams of 20 or more, some of its AI features are marked coming soon, and the $4.99 first-3-months offer reverts to $7.99
How we grade them
| 2.8GPASlackGood | 2.6GPAVoxerGood | |
|---|---|---|
| Value for money | CPro is $7.25 a user a month billed annually, $8.75 monthly, which is a shade above the $7 this category typically starts at. The parts people actually ask for next, SAML single sign-on and AI search, wait for Business+ at $15, double the middle figure. | CPro + AI is $4.17 a month billed yearly ($7.99 billed monthly) and Business is $6 a user, which sits between the cheaper quarter at $3.50 and the middle at $7. |
| Free plan and trial | CThe free plan keeps only 90 days of messages searchable, which for a team is the cap that hurts: ask what was decided in March and it's gone. Add 10 app integrations and huddles and external messages limited to 1:1, and there's no trial of Pro either. | BPersonal is free with live and recorded voice and groups of 500, but only 30 days of message storage. One person could live on it. |
| Features | AChannels, direct messages, threads, huddles with screen sharing, clips, canvases, lists and a no-code Workflow Builder, and two things its rivals here don't list: more than 2,600 apps in the directory, and Slack Connect shared channels with up to 250 other organizations. | CVoice, text, photos and location sharing do the job. It is a voice-first messenger with no tasks or channels, and Walkie Talkie mode and transcription are paid. |
| Ease of use | C4.1 on the App Store from about 53,000 ratings, the lowest of the big three here. Channels are simple enough to join, but a workspace left to itself sprawls, and the canvases, lists and Workflow Builder are each another thing to learn. | BNo store rating on record. It is an app you install and start talking on, with little to set up. |
| Platforms and integrations | AWeb, Mac, Windows, Linux, iPhone and Android, plus the biggest app directory in the category at 2,600-odd, Salesforce, Google Drive, Jira, Asana, Notion, GitHub, Zendesk and HubSpot among them. One oddity: in a browser, huddles work only in Chrome and Firefox. | BWeb, iPhone and Android with Zapier, Dropbox and an SDK, but no desktop app. |
| Best for | channel-based chat that plugs into everything | push-to-talk voice messages for field crews |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
