Help us measure

3 providers · startup time not yet measured

Provider	What we'd need	Why	Daily run, estimated
Vercel Sandbox	Pro, $20/mosource (opens in new tab)	Hobby's free quotas would cover the usage, but Hobby is for personal, non-commercial use only, and ColdTally is a commercial site. terms (opens in new tab)	334 sandboxes/mo, about $0.59 of usage, inside Pro's included $20 credit.
Browserbase	Developer, $20/mosource (opens in new tab)	The free plan includes 1 browser hour. That covers the daily run only with per-second billing. The pricing page doesn't state the billing increment, and per-minute rounding would need about 5.6 hours. pricing (opens in new tab)	334 sessions/mo, about 0.9 to 5.6 browser hours, well inside Developer's 100 browser hours.
Hyperbrowser	Startup, $30/mosource (opens in new tab)	The free 5,000 credits ($5) would likely cover the daily run for 8 months or more at these rates. They're a one-time allowance, so we'd need Startup once they run out. pricing (opens in new tab)	334 sessions/mo at $0.10/browser hour, about $0.09 to $0.56/mo.

Estimate: 11 runs a day (1 warm-up + 10 samples), 334 a month. Sandboxes: 2 vCPU default size, about 5 s of active CPU and the 60 s memory minimum per run. Browsers: up to 10 s per session (measured sessions take 2 to 3 s), and the low figure assumes per-second billing, the high one per-minute rounding. Prices from the ColdTally data, verified on each provider's pricing page.

Running the daily startup benchmark for these three needs a paid plan or ongoing credits. If you're one of these providers, or a community sponsor, you can cover it with credits or a sponsorship: sponsors@coldtally.com. Credits never affect rankings or numbers. Every provider runs the same open harness, all funding is disclosed on the methodology page, and every result is published in coldtally-data.
