pricingApp invocations are billed for active compute time, not per API call. The invocation rate in [Usage Rates](#usage-rates) is based on the current 4 GB memory allocation at $0.0000166667 per GB-second.Billing starts when your code begins executing and stops when it finishes. You aren’t charged for queued time, deploying an app, or leaving a deployed app idle. Failed and canceled invocations still accrue charges for the time they ran.Browsers created by an invocation are billed separately for their active runtime at the browser rates above. Services your code calls, such as an LLM API, also bill you independently.The app invocation limits are concurrency limits, not a number of invocations included with your plan.https://www.kernel.sh/docs/info/pricing#how-are-app-invocations-charged

Limitations and open questions

Known constraints and missing evidence from the collected pages.

The collected evidence does not mention any competitors by name. Gaps include lack of detailed information on data export, uptime SLAs, and specific security certifications beyond claims. Open questions remain about the exact nature of the 99.9% SLA and the specifics of HIPAA compliance.

This report is based on 15 collected pages from kernel.sh, including the homepage, about, docs, pricing, solutions, and customer stories. Evidence was gathered via static and browser rendering rendering. External proof search was enabled but no additional verification was performed. Limitations include potential marketing bias in customer stories and the absence of third-party review data.
