Slack for Nonprofits review - a free Pro upgrade for small teams

What it is

Slack for Nonprofits gives qualifying organizations the paid Pro plan for free on workspaces of up to 250 members. That removes the main limits of Slack’s free tier: you get full searchable message history and unlimited app integrations instead of the free plan’s rolling 90-day window.

What it costs and how to qualify

Free for eligible workspaces up to 250 members. Larger organizations can get an 85% discount on Pro or Business+ instead of the free upgrade. Eligibility runs through TechSoup, and once approved the upgrade is usually applied within a few days. Schools, hospitals, and private foundations are excluded.

Who it fits

Teams that already live in Slack and keep bumping into the free plan’s history limit. Getting the Pro features donated is a clean win. If your team is small and rarely searches old messages, the free tier may be all you need - and if you are already on Microsoft 365 or Google Workspace, Teams or Google Chat may cover this without another tool.

The honest take

An easy yes if Slack is already your hub and you are under 250 members. Free Pro is a real upgrade with no catch beyond the standard TechSoup verification. No affiliate relationship here - Slack does not pay us, this is listed because it genuinely helps small teams.
