Looks like one of the two families...
It is a member of Saxifragaceae, not Crassulaceae. You can tell this by the two styles fused at the base.
If you key it out in Stace you end up at Saxifraga. There don't seem to be additional genera present in Europe to confuse the issue, but European species may not conform to Stace's key. I looked up a book of alpine flowers, but there didn't see a convincing match - the nearest was Saxifraga diapensioides.
Cushion saxifrage would seem to do as imprecise identification - there may be a sectional name for this.
What looks different from the usual run of saxifrages (and Saxifraga diapensioides) is the broad sepals and narrow petals.
