How the parts of URLpipe work and why they were built that way.
- Why we built our own rendering engineOne warm Chrome, a fresh browser context per visit, about 900 lines with no dependencies — and the measurements that decided it.Read
- One page visit, several answersHow /scrape reads several results off one page load and stays identical to calling each endpoint on its own.Read
- Pacing a site that can't keep upWhen a target site falls over under load, slow down and try again — without failing the request or billing the wait.Read
- Why async is the defaultPages take seconds to minutes and sometimes much longer; a request that returns a token at once never loses the answer.Read
- Billing only what workedFailures, bot checks, duplicates, cache hits and waits are free — and the harder case, a 200 that is really a block page.Read
- Request timing as marks, not spansStore four moments per request and derive every duration from them — and publish exactly one number.Read
