Build in C++. Own the source.
Self-contained engines: one .exe, with the full C++20 source included. The shared core runs one worker per core with a durable journal, and every speed on this site is measured in microseconds on a real machine, not estimated.
- What: C++20 bots you run yourself
- Size: 1,273 KB, one file (Lot Line)
- Speed: 2.99 µs per deal, measured (Lot Line)
- Yours: source included, runs offline
Unzip, double-click START_HERE, and it opens in your browser.
START_HERE opens workspace.html from your own disk: no install, no server, no network. The engine runs inside the page (the same C++ code as the program, compiled to WebAssembly) with its results, charts and a terminal on one screen.
- C++ engine, 416 automated checks across 7 test suites, all passing (2026-09-28). The tests ship in the download.
- Measured 2.99 µs for one deal (amortise + evaluate, parse excluded) (334k/sec): the native program, 13th Gen Intel(R) Core(TM) i5-13420H · 12 threads, 2026-10-11. Your browser runs the same code more slowly, and the workspace shows its own time next to it.
- Blank until you run it, then only real numbers. It opens empty. Every figure after that is computed by the engine while you watch, or is a dated measurement. No sample deals, no market data, no invented live counters.
- Nothing to set up. No Python, no pip packages, no admin rights, no account. It opens a web page; it does not install software or open a port.
- Terminal inside the page. Type
bot analyse --price … --rent …and the engine prints what the program prints, and fills the panels. The full program is in the same folder: START_TERMINAL runs it in a terminal window. - One-time licence available.
