Browserless Cost Calculator

Enter browser sessions per month, average session length, proxy MB per session and captcha solves. The calculator converts them to Browserless units, prices each plan on monthly or annual billing including overage, skips plans whose max session time is too short, and shows the cost per 1,000 sessions. Estimates only; browserless.io/pricing prevails.

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.

How it works

What is a Browserless unit?: A unit is a block of up to 30 seconds of one browser connection. Longer sessions use one more unit for every further 30 seconds, and a session reconnect counts as a new connection. Proxy traffic adds 6 units per MB (residential) or 2 units per MB (datacenter), and each successful captcha solve costs 10 units.
