Browserless Cost Calculator

Formula: units = sessions × ceil(seconds ÷ 30) + sessions × (residential MB × 6 + datacenter MB × 2) + captcha solves × 10; total = plan price + units above the allowance × overage rate. A unit is up to 30 s of one browser connection; each further 30 s adds a unit, and a session reconnect counts as a new connection. Plans, monthly billing (annual billing per month): Free $0 — 1k units, 2 concurrent, 2-min sessions, no overage · Prototyping $35 ($25) — 20k units, $0.0020 / unit over, 15-min sessions · Starter $200 ($140) — 180k units, $0.0017, 30-min · Scale $500 ($350) — 500k units, $0.0015, 60-min; Enterprise custom. Plans whose max session time is shorter than your session are skipped. Concurrency (monthly / annual): Prototyping 5 / 10, Starter 30 / 40, Scale 80 / 100 — not modeled, check it against your parallelism. External proxies (bring your own) are allowed on paid plans and use no proxy units.
