CPU & memory
Instant info · optional short probe · Runs in this browser
Read the privacy-rounded device-memory hint when the browser exposes it, then optionally run a bounded in-page allocation and traversal workload to measure JavaScript memory throughput and verify the allocated data with a checksum.
Inspect the coarse memory hint the browser exposes, then optionally run a bounded JavaScript buffer-write probe in an isolated worker.
This cannot reveal exact installed RAM, available system memory, memory frequency, or native RAM bandwidth. Results describe this browser's JavaScript allocation/write path and can change with power mode and background work.
Transparent method
This tool reports only interactions and browser APIs it can observe. It does not infer hidden hardware specifications or turn unsupported access into made-up results.
Useful context
No. Supporting browsers provide a privacy-rounded and clamped estimate, not module size, type, speed, slots, or free system RAM.
No. A browser cannot reserve and validate all physical memory or bypass the operating system, so this is an in-browser memory information and throughput tool.
