Slack alternatives
Slack's per-seat pricing and 90-day free-plan history limit push most teams onto a paid tier quickly. These are the alternatives our reviews name, each with the reason it made the list.
Top Slack alternatives
Ranked by our editorial score.
A genuinely full-featured free tier with no member or channel caps, plus always-on voice channels — the pick for teams that prioritize cost over Slack's deeper workplace integrations.
vs Slack: Better value (9 vs 6) · Harder to use (7 vs 9) · Weaker support (5 vs 7)

Lighter alternative: “Microsoft Teams (bundled with Microsoft 365) or Discord for teams prioritizing cost over integration depth.”
* “Lower listed price” compares the entry prices in our reviews. Where the two tools price differently (per seat, per contact, per email sent), the cheaper option depends on your list size and sending volume.

How we picked them
Every alternative here is named in one of our own reviews — either in the Slack review (as a lighter or more powerful option, or in a head-to-head comparison) or in the other tool's review. Each relationship was then checked by hand: would someone replacing Slack reasonably consider this tool? Rankings follow our editorial score only; no tool pays to be listed or ranked.
Relationships drafted from our catalogue reviews on 30 September 2026 for this local preview. Before publication each row is confirmed by a Conversion Gems editor.
2 tools our reviews mention alongside Slack that we left out, and why
- microsoft-teams — Named explicitly in Slack's own review as a lighter alternative, but Microsoft Teams has no standalone catalogue page — our search of the live catalogue returned no Microsoft Teams entry.
- google-chat — Named in Slack's own comparison text, but Google Chat has no catalogue page.
