Signteer is a WordPress plugin that lets churches, schools, non-profits, and other volunteer-driven organizations post and manage sign-up sheets directly on their own website, without relying on a third-party service. Admins create sheets made up of individual tasks, each with its own capacity limit; volunteers browse the sheet and sign up for open slots on a page automatically given an SEO-friendly URL (yoursite.com/signupsheet/your-sheet/). The plugin sends customizable confirmation emails to volunteers after sign-up, and admins can edit sheets, clear slots, or manually assign volunteers to tasks from the WordPress dashboard. Built-in spam protection guards public sign-up forms. Signteer ships as a free 'Lite' version that is fully functional for evaluation, plus a one-time-payment 'Pro' license that unlocks CSV export of sign-ups (including task and volunteer details) and lifetime updates. It requires WordPress 5.8+ and PHP 7.4+, and is made by Plainware, a small, privately funded web development company that builds straightforward web tools for small and medium organizations.

Pros & Cons
Pros
Runs entirely on your own WordPress site, so volunteer data stays on infrastructure you control rather than a third-party platform.
Free Lite version is fully functional, letting organizations evaluate it with real sign-up sheets before paying.
One-time $39 lifetime license instead of a recurring subscription.
Unlimited sign-up sheets, tasks, and sign-ups even on the free tier.
Cons
Requires a self-hosted WordPress site (WordPress 5.8+ and PHP 7.4+) — not usable on wordpress.com's restricted plans or non-WordPress sites.
CSV export of sign-up data is locked behind the paid Pro license.
No mobile app or native calendar/CRM integrations mentioned — it's a standalone WordPress-only tool.
Very narrow feature set focused solely on sign-up sheets, not a broader volunteer or event management suite.
