Scored on how Dlit Easy Math Captcha is looked after — not on how many stores run it.

Well maintained
Not enough public feedback to put a confident number on this one. Little public feedback — score rests mostly on release activity. What we can see is below.

2 of 5 measures had too little evidence to score. They are left out of the total rather than counted as zero — otherwise a plugin would be marked down for being small rather than for being poorly kept.Measured 2026-09-09 from the WordPress.org plugin registry.
Ratings

No one has rated this plugin on WordPress.org yet. That is a statement about the ratings page, not about the plugin — plenty of well-kept plugins never collect them.

Dlit Easy Math Captcha adds configurable math captcha protection to:

  • WordPress comments
  • Login form
  • Registration form
  • WooCommerce product reviews
  • Contact Form 7 forms via [math_captcha]

Features:

  • Answer-digit based difficulty (1-3 digits)
  • Configurable operations: addition, subtraction, multiplication
  • Question style: digits, emoji (1️⃣3️⃣ ➕ 7️⃣), or mixed
  • Per-integration simple one-line mode to minimize UI impact
  • Stateless HMAC-signed single-use token verification (no database writes on page render)
  • Nonce verification for submissions

How do I use it with Contact Form 7?

Add this tag in your CF7 form (the name, e.g. captcha-1, lets CF7 show the validation error next to the field):

[math_captcha captcha-1]

Optional flags (no colons):

[math_captcha captcha-1 simple] – force compact one-line layout
[math_captcha captcha-1 full] – force full layout with description
[math_captcha captcha-1 light] – force light text mode
[math_captcha captcha-1 dark] – force dark text mode
[math_captcha captcha-1 id:my-id] – set a custom HTML id on the input
[math_captcha captcha-1 id:my-id simple] – combine id + compact layout
[math_captcha captcha-1 simple light] – combine compact + light text mode
[math_captcha captcha-1 id:my-id full dark] – combine id + full + dark text mode

Does it support Redis or Memcached?

Yes, automatically. Tokens are stored via the WordPress Transients API, so if your site uses a persistent object-cache drop-in (for example the “Redis Object Cache” plugin), tokens live in Redis/Memcached instead of the database with no configuration. The Settings > Math Captcha page shows which storage is currently in use.

Does it work with page caching?

Each captcha embeds a single-use token in the page HTML. If a full-page cache serves the same cached page to many visitors, only the first successful submission is accepted; later visitors must reload past the cache. Exclude pages with comment forms from full-page caching, or keep cache lifetimes short (under 30 minutes).
