One HTTP call from your controller or concern. Your forms stay clean, your UX stays intact, and every real submission gets through.
✓ Millisecond response time
✓ 99.5%+ accuracy
✓ Zero CAPTCHAs
✓ 1,000 checks for free
Built by the same team whose software is trusted by 30,000,000+ websites worldwide.
Everything You Need to Eliminate Spam in Rails
No gems to configure. No frontend scripts to load. Just a clean API that fits the way you already build.
before_action Callbacks
Protect any controller action with a single callback. Apply spam checking to your contact, registration, and checkout actions without cluttering your main logic.
Concerns for Reuse
Extract your spam checking into a shared concern and include it across controllers. Write the integration once and apply it everywhere with one line.
Active Job Integration
Process spam checks asynchronously using Active Job with Sidekiq, Resque, or any backend. Ideal for high-volume applications where you want to check submissions in the background.
Zero CAPTCHAs
Entirely server-side. Your users never see a puzzle, a checkbox, or a challenge. Your ERB and Slim templates stay clean.
Millisecond Speed
Spam verdicts return faster than most ActiveRecord queries. Form submissions process without delay. Your app stays fast.
Rails Credentials
Store your API key using Rails encrypted credentials. No plaintext keys in your codebase. Works with per-environment credentials in Rails 7+.
Turbo and Hotwire Compatible
ActiveLayer runs entirely server-side. Turbo Drive, Turbo Frames, and Turbo Streams work without modification. No JavaScript conflicts. No frontend dependencies.
Automatic Fallbacks
If ActiveLayer is unreachable, submissions pass through normally. Your application never breaks because of spam protection. Set a timeout and handle the edge case gracefully.
Rack Middleware Option
Protect routes at the Rack layer before requests even reach your controllers. Apply spam protection to your entire application or specific path patterns with a single middleware entry.
Protected in 3 Steps. Just Code You Already Write.
From API key to spam-free forms in under ten minutes.
1
Get Your API Key
Create a free ActiveLayer account and copy your API key. Store it in Rails encrypted credentials or as an environment variable. Standard Rails configuration.
2
Add the Spam Check to Your Controller
Call the ActiveLayer API from your controller action using Faraday or Net::HTTP. One POST request. One response. No gems to install.
3
Or Use a Concern for Reusable Protection
Prefer keeping controllers clean? Extract the spam check into a concern and include it wherever you need protection. Apply it with a single before_action callback.
Why Rails Developers Choose ActiveLayer
Your code stays clean. Your users stay happy. Your spam disappears.
Honeypot Gems Catch Bots. ActiveLayer Catches Everything.
Gems like invisible_captcha add a hidden field that worked five years ago — modern spam bypasses them entirely with headless browsers and AI-generated content that looks human. ActiveLayer analyzes actual content, email reputation, and IP signals using machine learning, catching the spam honeypots miss while maintaining the same invisible user experience. No frontend changes, no puzzles, just better detection that keeps pace with evolving threats.
Faster Than Your Average ActiveRecord Query
The recaptcha gem loads 300KB+ of Google JavaScript on every page, adding seconds to your load time and hurting your performance scores. ActiveLayer loads nothing on the frontend — zero JavaScript, zero cookies, zero impact on page speed. The spam check happens server-side when the form is submitted, returns in milliseconds, and your users never notice it’s there.
Controllers. Concerns. Callbacks. Your Choice.
ActiveLayer is a simple REST API that works with the patterns you already use — call it from a controller action, extract it into a concern, wrap it in a before_action callback, or process checks asynchronously with Active Job and Sidekiq. No gem lock-in, no custom view helpers, no monkey-patching. Just an HTTP call that returns JSON, integrated exactly how you want it.

Frequently Asked Questions
Have questions about ActiveLayer for Ruby on Rails? We’ve got answers.
ActiveLayer is a simple REST API. You can call it directly using Faraday, Net::HTTP, or any HTTP client. No gem is required. This keeps your dependencies minimal and gives you full control over error handling, timeouts, and retry logic. If you prefer a wrapper, the API is straightforward enough to wrap in a service object or concern in under 20 lines of code.
Yes. ActiveLayer runs entirely server-side. Turbo Drive form submissions, Turbo Frames, and Turbo Stream responses all work without modification. The spam check happens in your controller before you render or redirect. No JavaScript conflicts, no Stimulus controllers needed, and no frontend changes required. Your Turbo-powered forms work exactly as they did before.
Yes. Dispatch an Active Job that calls the ActiveLayer API after the form submission is accepted. This is ideal for high-volume applications where you want to check submissions in the background using Sidekiq, Resque, or any Active Job backend. Accept the submission immediately, check it asynchronously, and flag or delete spam after the fact.
Run `EDITOR=”code –wait” bin/rails credentials:edit` and add your key under an `activelayer` namespace. Access it with `Rails.application.credentials.dig(:activelayer, :api_key)`. This keeps your key encrypted in your repository and works with per-environment credentials in Rails 7+. You can also use environment variables with `ENV[‘ACTIVELAYER_API_KEY’]` if you prefer.
Yes. Add a before_action callback on the Devise RegistrationsController to check submissions before Devise processes the registration. Override the create action in your custom RegistrationsController, call the ActiveLayer API with the email and IP, and reject the submission if it’s flagged as spam. Devise handles the rest normally.
The invisible_captcha gem adds a honeypot field and timestamp validation to catch bots that fill in hidden fields too quickly. This works against simple bots but misses sophisticated spam from headless browsers and AI-generated content. ActiveLayer analyzes the actual submission content, email reputation, and IP signals using machine learning. It catches what honeypots miss while still being completely invisible to your users.
The recaptcha gem integrates Google reCAPTCHA, which loads 300KB+ of JavaScript on every page, adds seconds to your load time, and forces users to solve puzzles. ActiveLayer loads nothing on the frontend. Zero JavaScript. Zero cookies. The spam check happens entirely server-side in milliseconds. You get better detection accuracy without the performance penalty or the user friction that hurts your conversion rate.
Yes. 1,000 spam checks per month, no credit card required. Full API access with no feature restrictions. When you need more, upgrade to Pro at $19/month for 25,000 checks. One API key works across unlimited sites and applications.
