Mason is on the list but has not been graded yet. Nothing here is a judgement about the product or its API: it means the run has not happened. When it does, this page fills in with the score, all 27 checks and the full report, exactly like every platform already graded.

What Mason will be graded on.

The same five categories, the same 27 checks, the same weighting as every platform on the board. Nothing is tuned per vendor.

Letter grades are absolute, never curved.

The same numeric bands apply to every platform. Nothing here is scored relative to the rest of the board.

Work at Mason?

The fastest way onto the board is to run the grading file against your own API and send the result. It is the same file used for every platform here, it is public, and there is nothing in it that grades anyone favourably.

Use Mason and want it graded?

Say so. The order platforms get graded in is driven by what property managers actually ask about, and a request from an operator moves a platform up the list faster than anything else.

Found a factual error in your grade?

Tell us and we will fix it. Every mark on this page traces to a specific piece of first-party evidence or a live API call, and the full report is published so you can see exactly what was checked and what it was checked against.

Confirmed factual errors are corrected immediately.

Everything else waits. We do not rescore piecemeal on request, because a board where some vendors have been re-run and others have not is not a fair comparison. Shipped improvements, changed documentation and disagreements about judgement all go into the next full rerun.
