Tools that stay on your machine
The official robots.txt disallows /api/, /d2/, /import/, and /next/. I am not calling those paths. The three tools below use either text you paste or a file you drop, and the browser computes the result. There is no official save-code specification, so the code tool refuses to claim it parsed one.
What each one will and will not do
Save codes: empty input, whitespace and the documented length limit. It cannot detect invalid format, truncation or damage. Then you still import inside the game. Installers: byte size against the three HEAD responses from 29 October 2026. Not a hash the publisher signed, because no hash was published. Planner: difficulty-specific slot counts, character-level and catalyst checks for the documented routes, plus text export for build 20261028.2. It does not simulate DPS.
Questions and answers
Will these tools modify my save?
No. They do not write a code and they do not offer a download.

Source scope: the official site, FAQ, wiki and changelog share one publisher. Build IDs, installer sizes and detailed mechanics are single-source official claims unless a separate independent reference is identified. Several official links do not count as independent confirmation.
