Captcha integration
We integrate a captcha (reCAPTCHA, hCaptcha, Turnstile, etc.) on sensitive points — forms, login, registration, comments — to cut off bots and spam. Invisible/low-friction where possible, so as not to hinder people. To reduce automated spam and abuse. Honestly upfront: a captcha reduces mass bots and spam but does NOT catch 100% (advanced bots and solving services bypass it), adds friction for people and has accessibility nuances — it is a trade-off.
Captcha integration — overview
Captcha integration is a project: we pick a suitable captcha (invisible reCAPTCHA v3/Enterprise, hCaptcha, Cloudflare Turnstile, or privacy options without sending data to Google), place it on sensitive points (forms, login, registration, recovery, comments), set up thresholds/modes, server-side token verification, accessibility and a fallback. Honestly about the effect and limits, this is key: a captcha cuts off mass simple bots and noticeably reduces spam — a useful barrier; but it does NOT catch 100%: advanced bots, headless browsers and paid captcha-solving services (including with humans) bypass it; it is a barrier that raises the cost of attack, not 'full bot protection'. Honestly about friction and accessibility, important: a visible captcha adds effort for the user and can reduce form conversion; some captchas are problematic for people with disabilities (screen readers) and require an accessible fallback — so we prefer invisible/low-friction ones and carefully balance 'protection vs convenience'. Honestly about privacy: reCAPTCHA sends data to Google — if that is critical, we suggest privacy alternatives (hCaptcha/Turnstile); the legal assessment is given by a lawyer. Honestly about server verification: a captcha without server-side token verification is useless (the frontend is easily bypassed) — we do it right. Honestly about the business effect: less spam/bots, but we do NOT guarantee sales growth by itself (and an unnecessary captcha can even hinder). An important boundary: this is captcha integration (one tool), not bot management (740) and not rate-limiting (739) — they often work together. If there is no spam, a captcha may be overkill and only hinder. Picture this: instead of 'forms flooded by spam bots' — cutting off mass bots with minimal friction for people. The base price starts from 9,000 ₽ per project; it depends on the number of points.
Problems we solve
- Forms and registration are flooded by spam bots.
- Mass automated submissions and fake accounts.
- There is no protection of sensitive points from bots.
- You fear a captcha will scare off real users.
What's included in the Captcha integration service
- Picking a suitable captcha (invisible/privacy on demand)
- Placement on sensitive points (forms/login/registration)
- Server-side token verification (without it a captcha is useless)
- Setting up thresholds/modes and accessibility
- A fallback and a 'protection vs convenience' balance
- Privacy alternatives if needed (assessment — by a lawyer)
- Indicating boundaries (not 100%, solvers bypass)
- Handover and review with you
What you get
- Less mass spam and bots on forms
- Minimal friction (invisible/low-friction captcha)
- Correct server-side verification
- A barrier that raises the cost of attack (not 100% protection)
How the work goes: steps
- We clarify points, privacy requirements, audience; pick a captcha
- We add the captcha + server verification, set up accessibility/fallback
- We test on people and the balance, review with you

FAQ
Will a captcha fully stop bots?
No. It cuts off mass simple bots and noticeably reduces spam, but advanced bots, headless browsers and paid solving services (including with humans) bypass it. It is a barrier that raises the cost of attack, not full protection; it works in combination with rate-limiting/bot management.
Won't a captcha scare off users?
A visible captcha adds friction and can reduce conversion, plus accessibility nuances (screen readers). So we prefer invisible/low-friction options, make an accessible fallback and balance protection with convenience. If there is no spam, a captcha may be unnecessary.
What about privacy (reCAPTCHA and Google)?
reCAPTCHA sends data to Google. If that is critical, we suggest privacy alternatives (hCaptcha/Turnstile). The legal assessment (whether consent is needed) is given by your lawyer; we set it up technically.
