user1296: I want to help test the WIP Bitcoin Dev Kit "Add support for Taproot and tr() descriptors", PR #593 against other implementations besides Bitcoin Core (already testing again Core 22.0). In particular we need to test interoperability via PSBTs. BDK is based on rust-bitcoin and rust-miniscript so I'm only interested in projects not based on those libraries.
Does anyone know of any other wallet projects or libraries that support tr() descriptors and PSBTs that I can test with?
Thanks!

user47827: At the time of writing (May 2022) the only Bitcoin implementation other than Bitcoin Core (and Core derivatives like Knots) and rust-bitcoin I'm aware of that supports Taproot is btcd (Go). The associated btcd wallet recently merged Taproot PSBT fields.
Wallets that support sending and receiving to P2TR addresses are listed here. There are some new alpha Taproot wallets popping up (e.g. TapWallet) and Kalle Alm's btcdeb (script debugging utilities) supports Taproot.
The site outputdescriptors.org lists wallets that support descriptors generally but these may or may not yet support Taproot descriptors.
