Word stress and tone in 6,043 languages, taken from the published descriptions. Claude compiled the entries from the sources and they were then checked in several rounds; every entry quotes the passage it is based on, so you can check it yourself. Also here: the bibliography of those sources, and a calculator for stress typologies.

160,673listed sources, 8,600 languages
Every work we know of on each language's stress or tone: what it says, whether we have read it, and where to get it (free online, behind a paywall, or in a library). The whole list can be downloaded as a spreadsheet.
Open to everyone.
Part three
OT & HGparallel and serial
A calculator for stress typologies in Optimality Theory and Harmonic Grammar. Give it a constraint set and it works out every stress pattern the constraints can produce, exactly, and proves which patterns they cannot. Runs in your browser.
