Best Altcha solving service reviews
ALTCHA relies on a lightweight proof-of-work (PoW) mechanism to verify human interaction. Its key feature is replacing visual puzzles with a small cryptographic computation performed in the user’s browser, distinguishing real users from bots without using images, cookies, or tracking. On this page, different ALTCHA solvers are compared by their speed, accuracy, and integration methods.

Altcha
ALTCHA uses a lightweight proof-of-work (PoW) challenge: the page issues a JSON challenge, the browser performs a small cryptographic computation (nonce) or a remote solver does it, then returns a token proving legitimacy instead of image or interaction puzzles.
Automated solver flow: obtain the page challenge, perform the PoW (or run the same computation the browser would), return a valid nonce/token, and inject that token into the site's validation endpoint or JavaScript callback.
Resolution sequence:
- page issues a challenge JSON;
- client sends the challenge plus site context to the solver API (POST);
- solver computes the PoW and returns a token/nonce;
- client supplies the token to the site's validation endpoint or calls the site callback to complete verification.
How to bypass Altcha
Requirements for reliable automation: preserve page context (User-Agent, headers), reproduce the site's JavaScript timing and execution environment, implement the exact PoW rules (nonce format, difficulty), and support asynchronous token injection into the page's JS flow.
2Captcha and SolveCaptcha is best ALTCHA solving services.
Integration notes: solver APIs accept the challenge JSON and metadata and respond with JSON containing the token/nonce; SDKs exist for PHP, Python and Node.js to request a solve and then insert the returned token into the page or POST it to the validation endpoint.
Supported:
Browser extension option: an extension can capture the in-page challenge, forward it to a solver, and insert the returned token into the page's JS context — it must run in the same execution context and preserve timing and headers to match legitimate browser behavior.
ALTCHA Statistic
The monitoring service is based on a very great idea, the realization of the dreams most of us have always had for what the Internet can and should become.
