CaptchaLa

Description

Homepage: https://captcha.la/ · Dashboard: https://dash.captcha.la/ · Pricing: https://captcha.la/pricing

CaptchaLa is a privacy-first CAPTCHA and anti-spam service. This plugin is the official WordPress integration — it ships built-in protection for WordPress core forms, WooCommerce, and the most popular third-party form plugins, with one mandatory mode: server-issued tokens that can’t be replayed.

Why CaptchaLa?

  • Privacy-first. No personal-data harvesting, no behavioural ad signals, no tracking.
  • Stronger token contract. Every page render issues a server-side sct_ token bound to action + IP; the browser only ever ships back a single-use pt_ token. Replays, action mismatches, and IP changes are rejected at the SDK boundary.
  • Free tier for small sites. Paid plans for high-volume traffic and the optional content-moderation add-on.
  • No hand-coded image CAPTCHAs. The challenge is solved entirely by the CaptchaLa service — this plugin is thin glue.
  • Auto-detected form integrations. Drop the plugin in and the settings page lights up with the form plugins it found on your site.

Built-in protection points

  • WordPress core: login, registration, lost-password, comments
  • WooCommerce: classic + block checkout, pay-for-order, account creation, my-account login / register / lost-password
  • Third-party form plugins (auto-detected): Contact Form 7, WPForms, Gravity Forms, Forminator, Formidable Forms, Fluent Forms, Elementor Pro Forms, Divi Builder forms, BuddyPress, bbPress, Ultimate Member, MemberPress, Easy Digital Downloads, MailPoet

FAQ

Is CaptchaLa free?

A free tier covers small sites. High-volume traffic and content-moderation features require a paid plan — see https://captcha.la/pricing.

Do I need to install the SDK separately?

No. The PHP SDK is bundled in the plugin’s vendor/ directory by the build pipeline, so you don’t need Composer.

Does it work with my form plugin?

CaptchaLa ships first-class integrations for the 14 most-used form plugins on wordpress.org. See https://captcha.la/integrations/wordpress for the full list and the v1.1 roadmap.

Does it work with WooCommerce Block Checkout?

Yes. The Checkout integration covers both the classic shortcode-based checkout and the new block-based checkout.

Will it block logged-in admins?

No. By default the plugin skips CAPTCHA for users with manage_options or edit_others_posts. The toggle is on the settings page.

How does the server_token flow work?

On every page render the plugin issues a one-shot sct_ token from your CaptchaLa account, scoped to the action (login / register / checkout / …) and bound to the visitor’s IP. The browser SDK exchanges that token for a pt_ token after the human challenge passes. The plugin validates the pt_ token server-side on form submit. Replays, action-mismatches, and IP changes are all rejected.
