No puzzles. No lost leads. Your Next.js forms stay fast, your users stay happy, and spam never reaches your database.

✓ Zero CAPTCHAs
✓ TypeScript-first
Built by Awesome Motive, whose software is trusted by 30,000,000+ websites worldwide.
No more duct-taping honeypots, regex filters, and rate limiters together. ActiveLayer handles it all with one API call.
Call ActiveLayer directly from your Server Actions. No client-side code, no API route needed. Validate form submissions right where you handle them.
Drop a single `fetch` call into any API Route. Works identically in the App Router and Pages Router. No middleware configuration required.
ActiveLayer’s lightweight REST API works in Edge Runtime, Serverless Functions, and Node.js. Deploy anywhere Vercel runs your code.
Full type definitions for every request and response. Autocomplete for confidence scores, detection signals, and verdict objects. Zero guesswork.
No JavaScript loaded in your browser bundle. No impact on your Lighthouse score. No cookies. No client-side tracking of any kind.
Spam verdicts return faster than your database query. Your form submissions feel instant. Your users never wait for a spam check.
Every verdict includes a confidence score and specific detection signals. Log them, display them, or use them to build custom handling logic.
If ActiveLayer is unreachable, submissions pass through normally. Your forms never break because of spam protection. Your uptime stays yours.
One API key works across every Next.js project you deploy. No per-site fees. No per-domain restrictions. Ship as many apps as you want.
From signup to spam-free in under ten minutes.
1
Create a free ActiveLayer account. Copy your API key from the dashboard. Store it as an environment variable in your Next.js project.
2
Add a single `fetch` call to your existing form handler. ActiveLayer works in Server Actions, API Routes, and Edge Functions. No middleware. No wrapper libraries. Just a standard REST call.
3
Push to Vercel, Netlify, or any hosting platform. Every form submission is checked in milliseconds. View real-time stats, search past verdicts, and review detection signals in your ActiveLayer dashboard.
Your framework handles everything server-side. Your spam protection should too.
CAPTCHAs cost you up to 40% of form completions — every puzzle and image grid is a user who might abandon your signup flow or checkout page. ActiveLayer works entirely server-side: your users fill out the form, click submit, and move on with no challenges or friction. The spam check happens invisibly in your Server Action or API Route, keeping your conversion rate intact.
reCAPTCHA loads 300KB+ of JavaScript and hCaptcha loads its own scripts and stylesheets — both hurt your Lighthouse score and add latency to every page load. ActiveLayer loads zero client-side scripts, adding zero bytes to your bundle and zero impact on your Core Web Vitals. The entire spam check is a server-side `fetch` call that completes in milliseconds.
ActiveLayer works across every server-side pattern in Next.js — Server Actions, API Routes, and Edge Functions — with the same single `fetch` call. No framework-specific SDK, no middleware to configure, no dependency that locks you into one deployment model. Switch between the App Router and Pages Router freely; ActiveLayer doesn’t care how you architect your app.
ActiveLayer is built by Awesome Motive, the company behind WPForms, AIOSEO, MonsterInsights, OptinMonster, and 20+ products serving 30 million websites. That scale means spam detection models trained on billions of real submissions — patterns a solo developer would never see are caught instantly. You get enterprise-grade spam intelligence in a single API call, no ML expertise required.
Have questions about ActiveLayer for Next.js? We’ve got answers.
Both work identically. If you’re using the App Router with Server Actions, add the ActiveLayer check directly in your action function. If you prefer API Routes or are using the Pages Router, add it to your route handler. The integration is the same single `fetch` call either way.
Yes. ActiveLayer is a standard REST API, so it works in Edge Runtime, Serverless Functions, and Node.js runtime. No Node-specific dependencies. No file system access required. Deploy to Vercel’s Edge Functions and it works out of the box.
You can, but we recommend checking spam at the handler level instead. Middleware runs on every request, including page navigations. Checking at the Server Action or API Route level means you only call ActiveLayer when a form is actually submitted. This keeps your usage efficient and your costs low.
No. ActiveLayer is entirely server-side. Zero JavaScript, zero CSS, zero assets added to your browser bundle. Your Lighthouse score and Core Web Vitals are completely unaffected.
Yes. ActiveLayer checks happen at submission time, not at build time or revalidation time. Your ISR pages, static pages, and SSG pages are completely unaffected. The spam check only runs when a user submits a form.
Yes. ActiveLayer works anywhere your Next.js app runs. Vercel, Netlify, AWS, Railway, Docker, self-hosted Node.js. It’s a standard REST API call. If your server can make an outbound HTTPS request, ActiveLayer works.
ActiveLayer has automatic fallbacks. If the API doesn’t respond in time, you control the behavior. Let submissions through, queue them for later review, or reject them. Most developers set a timeout and allow submissions to pass through, so forms never break for real users.
Yes. 1,000 spam checks in total, no credit card required. Full API access with no feature restrictions. That covers most side projects and early-stage apps. When you grow past 1,000 checks, upgrade to Pro at $19/month for 25,000 checks.
