What works where

Fauna is one app on seven platforms and one small server. This page says, feature by feature, what has been proven to work on each of them — and it is not a promise page. Every mark below comes out of an actual test run: the run writes down what it saw, and this page is generated from that record.

That means it can tell you three different things, and the difference matters. A ✅ is a feature whose whole set of tests passed on that app. A ⚠ is a partial result: some passed, some did not, or the feature is only partly covered by tests so far. A ❌ means tests exist and none of them passed. A blank is the honest one — it says no run has been recorded yet, which is a statement about our records and not about the software; the feature may work perfectly and simply not have been re-tested on that platform since we started keeping this record. A — is different again: it means the feature is deliberately absent there, because the platform has no such thing.

We would rather show you a page with blanks in it than a page of green ticks we cannot back up.
