::: tip Note
|
|
|
|
"Hard for bots" does not consider commercial solvers like BrightData, as I cannot verify their legitimacy myself.

## All alternatives
|
|
|
|
### Cloudflare Turnstile
|
|
|
|
Cloudflare Turnstile is a great alternative to Cap, but unfortunately it is known for having an extremely high error rate and relies a lot on fingerprinting, especially for users using private browsers such as Brave or Librewolf. Additionally, unlike Turnstile, Cap is open-source and self-hosted.
|
|
|
|
### reCAPTCHA
|
|
|
|
Not only is Cap significantly smaller and faster than reCAPTCHA, it's open-source, fully free and is significantly more private. Cap doesn't require you to check traffic signs or solve puzzles, and it doesn't track users or collect data.
|
|
|
|
Additionally, reCAPTCHA v2 challenges can be solved trivially by multi-modal LLMs, especially audio challenges.
|
|
|
|
### hCAPTCHA
|
|
|
|
Pretty much the same as reCAPTCHA, however while it's significantly more resistant to bots, it is also extremely annoying for users to solve when prompted with a visual challenge compared to reCAPTChA. It also has a significantly bigger bundle size.
|
|
|
|
Additionally, hCAPTCHA is prohibitively expensive for many users, while Cap is completely free and self-hosted.
|
|
|
|
### Altcha
|
|
|
|
Cap is slightly smaller than Altcha and includes extra features like progress tracking, and a simpler dashboard. if you don't need these, Altcha is a still a solid choice.
|
|
|
|
### mCAPTCHA
|
|
|
|
While mCAPTCHA is similar to both Cap and Altcha, it seems to have been deprecated and has a significantly larger widget bundle.
|
|
|
|
### FriendlyCaptcha
|
|
|
|
Unlike FriendlyCaptcha, Cap is completely free and self-hosted (FriendlyCaptcha is €39/month for 5k requests and 5 domains).
|
|
|
|
### MTCaptcha
|
|
|
|
Cap is more lightweight, doesn't rely on users solving an image puzzle that LLMs and OCR can easily solve and is open-source and self-hostable.
|
|
|
|
### GeeTest
|
|
|
|
Cap is free, self-hosted and open-source, while GeeTest is a paid service. Cap is also more private and doesn't rely on tracking users or collecting data. GeeTest is also china-based, which may be a concern for some users.
|
|
|
|
### Arkose Labs
|
|
|
|
Arkose's CAPTCHA is known for being hard, slow and annoying for humans to solve. It is also a paid, closed-source service.
|
|
|
|
### Anubis
|
|
|
|
While Anubis is a great scraper deterrent and uses the same proof-of-work concept as Cap, it uses a low difficulty by default (which is easier for bots to solve) and does not provide a standalone CAPTCHA.
