Would an open-source CAPTCHA project be a good idea?
I’m thinking about building an open-source CAPTCHA project and would love to get some honest feedback before I start.
The basic idea would be a self-hostable CAPTCHA solution that developers could run themselves instead of relying on services like reCAPTCHA or other third-party providers.
Some things I’m considering:
\- Open-source and transparent implementation
\- Self-hosted / privacy-friendly
\- Easy integration with websites and APIs
\- Modern challenges that are accessible to legitimate users
\- Protection against common automated/bot abuse
\- Potentially offering different challenge types depending on the use case
I’m wondering:
1. Is there actually a need for an OSS CAPTCHA solution?
2. What are the biggest problems with existing CAPTCHA systems?
3. What features would make you consider using a self-hosted OSS CAPTCHA?
4. Are there technical/security challenges that would make this difficult to maintain as an open-source project?
5. Would you personally use something like this in a project?
