Yes. Slack has a Free plan that costs $0. It works for basic team communication, but the limits on searchable history, file retention, apps, huddles, and external collaboration may matter if you rely on Slack every day.
What Slack Free includes
Slack describes Free as a way for small teams to communicate and stay connected. The plan costs $0, and you can use it without subscribing to a paid plan. Slack’s pricing page lists the current plans and features.
What are the limits of Slack Free?
Messages and files: 90-day access is not the same as permanent retention
On Free, you can see and search the most recent 90 days of messages and files. That is an access and search window, not a promise that older content remains available indefinitely. Slack says messages and files more than one year old may be permanently deleted from Free workspaces on a rolling basis. The 90-day visibility limit and the possible deletion after one year are separate limits. See Slack’s usage limits for free workspaces.
Apps: up to 10 installations
A Free workspace can install up to 10 third-party or custom apps. Teams that depend on a larger set of integrations may need a paid plan.

#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.

Huddles: two participants
A Free huddle can include no more than two participants. Slack’s huddle guidance says paid plans allow up to 50 participants; up to 25 people can enable video at once.
Slack Connect: limited external collaboration
Free restricts Slack Connect to one-on-one external direct messages and does not include Slack Connect channels. If your team collaborates with other organizations in shared channels, this is a significant functional difference.

Slack Free versus Pro
Slack’s plan pages distinguish Free from Pro on history, apps, meetings, and external collaboration. Pro includes unlimited message history and app integrations, group meetings, and group external messages. These are plan descriptions; confirm current feature availability and terms on Slack’s pricing page.
| Feature | Free | Pro |
|---|---|---|
| Price | $0 | On 2026-10-07, Slack displayed $8.75 USD per user per month with monthly billing or $7.25 USD per user per month with annual billing. Pricing is subject to change; verify the live price before subscribing. |
| Message and file history | Most recent 90 days visible and searchable; content older than one year may be permanently deleted on a rolling basis. | Unlimited message history, according to Slack’s plan page. |
| App integrations | Up to 10 third-party or custom app installations. | Unlimited app integrations, according to Slack’s plan page. |
| Huddles and meetings | Up to two participants per huddle. | Group meetings; Slack says paid-plan huddles support up to 50 participants, with video enabled by up to 25 at once. |
| External collaboration | One-on-one Slack Connect direct messages; no Slack Connect channels. | Group external messages, according to Slack’s plan page. |
When is Slack Free enough?
Free can be a reasonable fit if your team mainly needs ongoing chat, has modest integration needs, and does not rely on Slack as a long-term searchable archive. The plan becomes harder to work with when you need older discussions or files, more than 10 app installations, larger huddles, or shared Slack Connect channels.

What happens when a paid trial ends?
If a workspace does not upgrade when its paid trial ends, Slack automatically returns it to Free. Free limits are reapplied and paid features are removed. Check Slack’s trial-end guidance and make sure the workspace’s usage fits the Free limits before the trial expires.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Before downgrading a paid workspace
Slack recommends reviewing workspace analytics before leaving a paid plan so you can understand how much content will become unavailable under the 90-day limit and how much could eventually be deleted. The change also affects Slack Connect and huddles: Free removes Slack Connect channels and limits huddles to one-on-one. Review your records and collaboration setup before switching, using Slack’s downgrade guidance.
