Why this matters for platform owners
If you run a builder, platform, marketplace, hosted CMS, or app ecosystem, spam is not only a moderation problem. It also affects product quality, support workload, conversion, and user trust.
- protect customer forms and signups at scale
- reduce spam complaints from end users
- keep inboxes, dashboards, and CRMs cleaner
- improve user experience compared to CAPTCHA
- add platform value with one anti-spam integration

Why platforms and builders integrate CleanTalk
CleanTalk is useful not only for single websites, but also for platforms and products that handle large volumes of user-generated submissions.
- protect multiple submission points with one anti-spam layer
- reduce fake registrations and spam form entries
- keep inboxes, dashboards, and CRMs cleaner
- lower moderation and support workload
- improve UX compared to CAPTCHA
- add extra value for your users
- fine-tune protection for different workflows
Why CleanTalk is better than CAPTCHA
CAPTCHA often creates friction for legitimate users. CleanTalk protects forms and submissions in the background, which makes it easier for real people to interact with your app or platform.
| Feature | CAPTCHA | CleanTalk |
|---|---|---|
| User friction | High | Low |
| Invisible protection | No | Yes |
| Mobile-friendly UX | Limited | Better |
| Admin logs | Limited | Yes |
| Personal allow/block lists | No | Yes |
| App-specific tuning | Limited | Yes |
| Support | Usually limited | 24/7 |
CAPTCHA is a challenge. CleanTalk is a full anti-spam system.

Tuned for each app, platform, and workflow
Different platforms attract different spam patterns. A form builder, a hosted CMS, a marketplace, and a custom SaaS product do not need identical protection logic.
- Global filters — broader anti-spam signals based on service-wide intelligence
- Custom filters — additional logic for specific apps, workflows, or customer needs
- Workflow tuning — registrations, comments, orders, and contact forms can be handled differently
- Platform-aware setup — protection can be adapted to the way users interact with your product
How CleanTalk works
- A user submits a form, registration, order, comment, message, or another request
- The request is sent via API or integration
- CleanTalk analyzes the submission
- Global and custom filters are applied
- Legitimate traffic is approved, spam is blocked or flagged
- Logs and lists help admins review activity and manage exceptions
This model works for both individual websites and platforms serving many users.
