Price, side by side
One hourly rate per environment, billed per second while it runs. The same browser or 4 vCPU / 8 GB sandbox on every other provider, at their list prices.
Per hour, one browser
Cloud browser session, wall-clock hour, public list prices as of 2026-10-06.
$0.050/h
Per hour, one sandbox
4 vCPU / 8 GB / 20 GB disk, wall-clock hour, public list prices as of 2026-10-06.
Prices as of 2026-10-06, taken from each provider's public pricing page (each name above links to it). Browsers: one session-hour at the provider's lowest self-serve rate. Kernel bills $0.060 per GB-hour of browser memory; $0.180 assumes a normal average browser workload of about 3 GB RAM, and actual RAM usage may be higher. Sandboxes: compute is 4 × the provider's published $/vCPU-hour plus 8 × its $/GB-hour; the disk column adds 20 GB of running disk at the provider's storage rate where it bills disk separately. Solari, exe.dev, E2B, AWS AgentCore and Modal include that disk at no extra charge. Cloudflare, Vercel Sandbox and AWS AgentCore bill CPU on active seconds only, so their rates are full-use list prices. AWS AgentCore is the v1 runtime; its v2 runtime lists $0.1276 per vCPU-hour and $0.0169 per GB-hour ($0.646 per hour). Fly.io Sprites reflects the 1 October 2026 price cut. Modal is its Sandboxes tier. Solari rates are the Enterprise tier ($0.0175 per vCPU-hour, $0.0055 per GB-hour, $0.05 per browser hour); see docs.getsolari.com/pricing for every plan. Plan fees, included credits, snapshots and taxes excluded. Solari bills per second while an environment runs.
Performance, measured
Price per hour is half the story. The other half is how fast an environment is ready to work.

A typical sandbox assumes 4 vCPUs and 16 GB RAM. A typical desktop assumes 1 vCPU and 2 GB RAM plus the live screen. *Kernel bills per GB-second of browser memory: $0.0000166667 per GB-second ($0.060 per GB-hour), idle time excluded. The $0.180 per hour shown assumes a normal average browser workload of about 3 GB RAM; actual RAM usage may be higher. Kernel's own rate card lists a 1 GB headless browser at $0.060 per hour and an 8 GB headful browser at $0.480 per hour. CodeSandbox has no 4 vCPU / 16 GB size; its Small VM (8 vCPU / 16 GB) is shown, and its free Build plan publishes no monthly credits, so none are assumed.
Estimate only, at list rates from each provider's public pricing page, as of October 6, 2026: docs.getsolari.com/pricing · browserbase.com/pricing · e2b.dev/pricing. Bill = plan fee + usage beyond included monthly credits. Sign-up credits are excluded. "Over limit" means that vendor's free tier cannot buy that many hours. Solari has no hard cap: usage beyond included credits is bought as top-up credits. Proxies, captchas, storage, and taxes excluded. Solari recommends Enterprise at 10,000 total hours per month.
