Verified core factsChecked 2026-10-10
Free

$0 / mo

Free workspace with 90 days of searchable message history and up to ten app integrations. Free data is deleted after one year. Huddles and external messaging are one-to-one; group meetings and unrestricted history require a paid plan. Paid rates were localized, so no USD paid rate is asserted.

What it helps you do

Collaborate with my team
  • Channels organize discussions around teams, projects and topics.
  • Messages and files can be searched within the retained history.
  • Free provides one-to-one audio/video huddles and external direct messages.

Documented product-level capabilities. Selected plan limits and add-ons still apply.

Why consider it

  • Shared channels reduce fragmented project communication.
  • A free workspace can connect a limited set of business apps.

Trade-offs to consider

  • Free only exposes 90 days of message history and deletes data after a year.
  • Group huddles and broader external collaboration require paid plans.

Intended users

  • Small teams coordinating day-to-day work
  • Agencies organizing client delivery conversations
  • Distributed teams sharing project updates
