Cheapest option at increasing browser-hours
Same proxy GB as your input above, only monthly browser-hours change. Watch how the cheapest plan flips once usage clears each plan's included allowance or flat fee.

Why browser-hour + proxy bandwidth pricing shapes matter
Headless browser vendors for AI agents (Browserbase, Steel, Browser Use) meter two independent things: browser-hours — how long a Chrome instance stays alive — and proxy bandwidth — how much data flows through the managed proxy pool used to avoid IP blocks and solve CAPTCHAs. Browserbase and Steel wrap both into tiered plans: a flat monthly fee buys a block of included browser-hours and included proxy GB, and every unit past that block is billed at an overage rate. The real monthly cost is therefore plan fee + max(0, hours − included hours) × hourly overage + max(0, GB − included GB) × proxy overage. At low usage the flat fee dominates the bill regardless of how low the overage rate looks; once usage clears the included allowance, the overage rate becomes the real driver of cost, and a plan with a higher fee but a larger allowance and cheaper overage rate can become the better deal.
Browser Use takes a different shape entirely — pure metered pricing with no flat plan fee and no published included allowance, currently around $0.02 per browser-hour. That rate is roughly 5-6x cheaper per hour than Browserbase's or Steel's overage rates, but it is not a like-for-like comparison: Browserbase and Steel bundle managed residential/datacenter proxies, automatic CAPTCHA solving and anti-detection stealth into their pricing, while Browser Use's published rate has no separate proxy line item, which usually means sourcing and paying for that infrastructure yourself. A workload that leans heavily on proxy-hungry, CAPTCHA-heavy scraping can end up cheaper on a bundled plan even though the raw hourly rate looks higher on paper — always compare total delivered cost for your actual workload, not the headline per-hour number.
How this calculator works
The Headless Browser Infrastructure Cost Calculator compares three vendor pricing shapes — Browserbase, Steel and Browser Use-style — at your monthly browser-hours and proxy bandwidth. Browserbase and Steel each offer two plans: a lower-fee plan with a smaller included allowance and higher overage rate, and a higher-fee plan with a larger allowance and lower overage rate. Each plan's cost is plan fee + max(0, hours − included hours) × hourly overage + max(0, GB − included GB) × proxy overage (Steel's flat-fee tiers apply a monthly usage credit against metered usage instead of an included-hours block). The calculator computes both plans for each vendor and shows the cheaper one, then computes Browser Use's pure metered cost — hours × $/hour, with no plan fee and no proxy line since Browser Use does not publish one. Total monthly cost divided by browser-hours gives the effective cost per hour for each option.
These are representative pricing shapes based on typical published rates, not live vendor quotes — actual Browserbase, Steel and Browser Use pricing changes over time and can vary by region, concurrency tier and negotiated enterprise contract. Browser Use's total in this calculator excludes proxy bandwidth entirely since no public per-GB rate is published; if your workload needs managed proxies or CAPTCHA solving, budget that separately before comparing it head-to-head with Browserbase or Steel. Always confirm current pricing directly with the vendor before budgeting.
Frequently asked questions
How much does headless browser infrastructure cost for AI agents?
Published rates cluster in a rough $0.02-$0.12 per browser-hour range depending on vendor and plan tier, plus a separate proxy bandwidth charge that commonly runs $6-$12 per GB once you exceed the plan's included allowance. Some vendors also charge a flat monthly plan fee ($20-$250) that bundles in a block of included browser-hours and proxy GB. These are illustrative typical published ranges, not live quotes — actual pricing changes over time and varies by region and contract, so always confirm current pricing directly with the vendor before budgeting.
Why do Browserbase and Steel charge separately for proxy bandwidth?
Browser-hours measure how long a headless Chrome instance runs, while proxy bandwidth measures how much data flows through the vendor's residential/datacenter proxy pool to avoid IP blocks and solve CAPTCHAs on the sites being automated. These are genuinely separate cost drivers — a short session scraping a data-heavy page can burn far more proxy GB than a long session on a light page, and vice versa — so vendors meter and price them independently rather than folding proxy cost into the hourly rate. Ignoring the proxy line item is the single most common way teams underestimate their real monthly bill.
Is Browser Use always cheaper than Browserbase or Steel?
On raw browser-hour pricing, yes — Browser Use's metered $0.02/browser-hour rate undercuts Browserbase's and Steel's overage rates by roughly 5-6x. But that comparison is not apples-to-apples: Browserbase and Steel bundle managed proxy pools, automatic CAPTCHA solving and anti-detection stealth into their per-hour and per-GB pricing, while Browser Use's published rate does not include a published proxy line item, meaning you likely need to source and pay for proxy/stealth infrastructure separately. Compare total delivered cost for your actual workload, not just the headline browser-hour rate.
Which plan should I choose — Browserbase Developer/Startup or Steel Launch/Scale?
It depends on your monthly browser-hours and proxy GB relative to each plan's included allowance and flat fee. A plan with a low or no monthly fee tends to win at low volume because you are not paying for unused included hours; a plan with a higher flat fee but a larger included allowance and lower overage rate tends to win once your usage clears that allowance. Run your own browser-hours and proxy GB through the calculator above rather than assuming the cheapest-looking sticker plan is actually cheapest at your volume, and re-check as your usage grows since the cheapest plan can flip.
