SignUpGenius
The free tier alone makes this the default choice for PTAs, church groups, and small volunteer coordinators, and the paid tiers are cheap enough that removing ads and adding co-admins is an easy upgrade once an organization outgrows the basics.
What it does
SignUpGenius replaces reply-all email chains and shared spreadsheets with online sign-up sheets for volunteer shifts, classroom supplies, potlucks, and events. Organizers create a sign-up, define slots and limits, and share a link for people to claim a spot. Paid tiers add automated reminder emails, payment collection for events with a fee, custom branding, multiple admin access, and slot-locking to prevent last-minute changes, while the core scheduling functionality remains free on every plan.
