One address.
Everything that is wrong.
Seven checkers, run at once. Each one says what it measured and what it could not, and nothing here is scored on a check that did not run.
This tool works differently from the generator. The generator never uploads your image — it runs in your browser. The checker cannot: it fetches the public address you type, from our server, and reads that page, and its robots.txt. Only the address you enter is sent. Nothing is stored: this page keeps no history of what you check.

Once these are settled
Each finding above opens the tool that fixes it, with this address already filled in. There are more tools than the 9 run here — the image ones take a file rather than an address, so they cannot be run from a URL.
