HubSpot's free CRM is the benchmark for free CRM software. Unlimited contacts, unlimited deals, email tracking, meeting scheduler, live chat, and a Gmail/Outlook sidebar — all at no cost. The free tier has no contact limit, no deal limit, and no user limit. Upgrade costs kick in for advanced automation and marketing tools.

Zoho CRM free supports up to 3 users with full pipeline management, contact tracking, lead scoring basics, and workflow rules.

Slack free includes unlimited channels, direct messages, and up to 10 apps/integrations. Message history is limited to the last 90 days on the free plan. For small teams under 10 people where communication is primarily about current work (not historical reference), the free tier covers most needs.
