Best Scheduling Software Alternatives in 2026
Looking for an alternative to When I Work, Deputy, Sling, or Homebase? Senzii is free and open-source, with AI-powered shift matching that considers skills, proximity, and certifications — features no competitor offers for free.
Why Teams Switch to Senzii
Most scheduling software gives you a digital calendar and leaves the hard work to you. Senzii is different — it uses AI to automatically match the best staff member to each shift based on skills, proximity to the work site, certifications, and performance history. No more spending hours assigning shifts manually.
Senzii is free and open-source under the Apache License 2.0. No tiers, no per-seat fees, no per-location fees, no feature gates. Self-host it or use the hosted version — same features either way. You can even talk to your schedule through ChatGPT or Claude via MCP integration.
