You pay per successful solve — never for failures. CPM is the equivalent cost per 1,000 solved captchas.
Every captcha is solved in a real headless browser, orchestrated by a purpose-built infrastructure that just works.
Sub-second median solve times. Parallel workers and smart queuing keep latency low even under bursts.
No text-matching guesswork. Each solve runs in an isolated Chromium profile, so tokens pass the toughest challenges.
A single REST endpoint, an SLA-backed uptime guarantee, and monitoring that catches issues before you notice them.
Tokens are only used once, logs are scoped, and each solve is isolated — your credentials stay yours.
Pay per successful solve. No subscriptions, no minimums, no surprise invoices. Payments are coming soon.

Email contact@passfast.dev with a few words about your project. We're onboarding in batches, and we'll get back to you as soon as we can.
Cloudflare Turnstile today, with hCaptcha and reCAPTCHA v2/v3 on the roadmap. Every solve runs in a real browser session.
No crowdsourcing, no human-in-the-loop. Solves are performed by automated real browsers on our own infrastructure, with strict rate limits and per-account quotas — keeping the network healthy for everyone.
A single authenticated HTTP request returns a token. We provide SDKs and a copy-paste example for every language we ship.
Pay per successful solve only. Pricing is finalized along with the dashboard — email us and we'll give you the current rate.
Join the early cohort and get first access to the dashboard when it ships.
