About StealthASF

We make the blocked
web readable.

The public web is drowning in bot walls and overpriced “JS render” credits. StealthASF is one honest API that gets past the wall, reads the data, and bills you only for what the request actually used — up to 60% cheaper than ScrapingBee.

Why we exist

Scraping turned into a bot fight. We took the fight out.

Getting public data used to be a one-line fetch. Then came Cloudflare, DataDome, JS-only pages and scraping APIs that charge a fat render credit on every call — even the ones that never needed a browser. We were tired of paying twice and babysitting headless Chrome. So we built the tool we wanted.

THE ENGINE

Adaptive, not brute force

We try the cheap real-browser-TLS HTTP path first and only spin a full anti-detect browser when a site truly needs it. No navigator.webdriver, no automation leaks — we pass by looking human, not by hammering. The savings are passed to you, not pocketed as a “premium credit”.

THE TRICK

We find the hidden API

Most pages are powered by an internal JSON API. We discover it and return clean structured data instead of fighting rendered HTML — faster, cheaper, more reliable.

THE PRICE

Pay for what you use

HTTP first, browser only when needed, billed per the actual work. That’s the whole reason we land ~60% under the “render-credit-on-everything” crowd.

Under the hood

Real browsers. Real TLS. Real residential IPs.

Not a wrapper around someone else’s API — a real stealth stack we run end to end.

STACK 01

Anti-detect browser

A patched Firefox engine spoofs canvas, WebGL, fonts, screen and the WebDriver flag at the C++ level — undetectable by JS probes.

STACK 02

Genuine browser TLS

Byte-identical JA3/JA4 + HTTP/2 fingerprints. To the server, the handshake is indistinguishable from a real Chrome or Firefox.

STACK 03

Residential rotation

A fresh real-ISP exit IP per request, geo-targetable, with the WebRTC leak sealed shut so your real IP never escapes.

How we operate

A real company — not a shady proxy in a trench coat.

Stealth is for accessing public data without being wrongly blocked — not for breaking the law. We build it that way on purpose.

YOURS

You own your flows

You define what to fetch — by API or the no-code builder. We give you the engine; you point it at your targets.

FAIR

We respect the limits

Sensible rates, no DoS, no credential stuffing, no fraud. The tool refuses internal/metadata targets and is monitored for abuse.

CLEAR

Honest billing

Transparent per-credit pricing, 1,000 free calls every month, cancel anytime. No “talk to sales” maze (it’s just us).

Built by people who got tired of getting blocked.

Try it on your hardest target. 1,000 free calls every month, no card. First clean scrape in under a minute.
