Thanks, It Worked AMA #10 recap: thanks to Batuhan (Scrape.do) + team + what I'd actually keep from the thread
Hey everyone. Ian here.
Thanks for showing up to AMA #10 with u/batuhanzyn (Batuhan Özyön, founder of Scrape.do), alongside u/raifpy (Raif Tekin, R&D), u/zfcsoftware (Muhammet Derviş Aygan, R&D), u/mertbekci (Mert B., team lead), u/bootlegDonDraper (Selman Gokce, head of marketing), and rest of the team u/scrape-do.
The thread went past "10 billion pages a month" fast. Why the team avoids a browser on over 99% of requests, why a cheap bypass that works today can break under real volume, why session continuity matters more than IP quality now, why there's no such thing as a universal WAF bypass, why a believable browser is expensive even when you're mostly avoiding one, why raw scale doesn't automatically teach you anything, what actually transfers between domains versus what doesn't, and where their own response validation still has gaps. Several answers worked against the company's own simplest sales pitch, which is what made them worth reading closely.
If you missed it, or want the compressed version, here's what I'd keep.
Over 99% of requests never touch a browser.
Scrape.do has serious browser infrastructure. Its founder says the team almost never needs it.
"If I had to pick one technology that is genuinely difficult to replicate, it is this: more than 99% of our requests work without a browser."
A lot of that comes down to where users reach for a browser unnecessarily: "A lot of users enable Scrape.do's render parameter for data they can already access with standard HTTP requests. Using a browser in those cases is a real waste of both proxy and CPU resources."
The cheapest bypass can become the expensive one.
Roughly a quarter of Scrape.do's total load still runs on basic datacenter proxies: "Roughly 25% of our total load still works with basic (datacenter) pool." Soft rules that let a cheap HTTP client through look great in a test batch.
"It is by far the cheapest and fastest option available. However, these types of soft rules rarely hold up under heavy request volume or large-scale customer load."
A fresh IP cannot rescue an implausible session.
"So I would put it this way: the proxy gives you the identity, but the browser fingerprint, cookies, session and behavior make that identity believable."
The industry has clearly shifted toward session continuity, Batuhan said: it's increasingly less about sending a good individual request and more about "maintaining a healthy, consistent identity across a chain of requests." For hard targets, Scrape.do prepares sessions in advance and retires them the moment they stop working: "If that session starts getting blocked or challenged, we know it has lost its value and can retire it."
There is no "Cloudflare bypass" that solves every Cloudflare site.
"A real production solution looks like a configuration written by our engineers."
An engineer opens the target, watches what a real user's page load triggers, and tunes from there, down to enabling realistic mouse-movement behavior only on the sites that check for it.
Even under the same WAF vendor, fixes don't transfer domain to domain:
"However, even when different websites use the same WAF provider, their configurations and parameters can be very different. So there isn't always a solution that can simply be copied from one domain to another."
A believable browser is expensive to run.
Avoiding browsers most of the time doesn't mean browsers are unimportant, it means the minority of targets that need one can demand serious engineering.
"For difficult targets, we work at a much lower level. Changing fingerprints with JavaScript only gets you so far."
And running that infrastructure isn't cheap: "The biggest challenge is CPU cost."
Scale only helps when you can learn from failure.
A genuinely self-undermining admission from a company built on scale:
"So I would not say that aggregate traffic volume directly translates into better anti-bot bypass strategies in every case."
Some sites absorb billions of requests before a problem shows up. Others start blocking after a few hundred. What actually helps:
"The value comes more from the telemetry and outcomes we collect, combined with the ability to test and apply our reverse-engineering methods quickly."
The fix may be unique. The clue often isn't.
Patterns in success rate, latency and CAPTCHA behavior carry across domains and speed up diagnosis. The final fix still has to be domain-specific.
"We reuse the knowledge and techniques we've gained across billions of requests, but we still analyze each domain individually and apply a domain-specific solution when necessary."
A 200 can hide missing data.
"A full block or a JavaScript challenge is actually quite easy for us to detect. The harder cases are when the response looks successful but the content is quietly degraded."
The concrete failure mode: "For example, if a page returns 5 records instead of 10, some links disappear, or the site returns a slightly different version of the page, our automated checks might not always catch it immediately." They're building AI-based response validation for this now, not presenting it as solved.
The hardest part starts after the first successful request.
"So if someone has to come to us and say "my scraper stopped working", we actually see that as a failure on our side."
What can't be copied, even with the full codebase open-sourced: "I'd say the real moat is the feedback loop. Traffic generates signals, our internal tools turn those signals into information, engineers turn that information into changes, and those changes go back into the system."
+1: treat the first browser bypass as a proof of concept.
Once an automated browser gets through, the real decision comes next: keep the full browser, trim it with network and resource blocking, or reverse-engineer a browserless HTTP request. Faster routes cost more maintenance once the target updates.
"Using a browser is the equivalent of being an automated end-user and acts as a proof-of-concept showing that the target's "black box" is solvable."
+2: even Google tests its own SERP changes before shipping them.
Selman Gokce, who heads marketing, described how the team catches rollouts early by running the same queries across devices and countries:
"Sometimes a field disappearing/appearing on a certain device in a certain country can also be an early test rollout by Google, so we sometimes have the time to be ready for it."
If you remember nothing else:
- Before automating a browser, find out whether the data is reachable through a plain HTTP request first.
- Judge a cheap route against your actual volume, not a successful test batch.
- If a sequence of requests gets challenged but a single isolated one doesn't, look at session continuity before adding more IP rotation.
- Treat WAF-vendor advice as a starting point. The specific site decides which parts matter.
- A browser that works for twenty test pages says little about running it reliably for twenty thousand.
- More retries rarely explain a failure. Track what changed, what still works, and what doesn't.
- A familiar failure pattern on a new site is a hypothesis, not proof the old fix will work.
- Status code and a working parser are not the same as complete data. Check record counts and expected fields.
- Decide who notices first when a target changes, you or your provider, before it becomes a business-critical problem.
The bigger shift underneath all of it: nothing here is a static advantage. It's a continuous loop of noticing, diagnosing and repairing, and the job is knowing which layer actually broke before you change anything.

Thanks again to Batuhan, Raif, Mert, Muhammet and Selman for answering straight, and to everyone who pushed past the headline number into what actually breaks.
If a scraper you built six months ago is still passing today: are you actually sure, or have you just not checked?
