Write math. Run it here.

Execution happens in your browser, in the JMax evaluator compiled to WebAssembly. Every run returns the result, the size of the computation graph, and a timing reading. No server, no account — nothing leaves the page. Press Run or Shift + Enter.

⋆ The browser sandbox reports wall-clock time and the evaluated graph size. On the CLI and native runtimes, JMax attaches a measured energy receipt in joules with its sensor source — the same number, metered rather than modeled.
