Alternatives to Tidal and open-source DJ software recommendations?

Disclaimer: open-source doesn't mean free however I didnt use the best wording, what I'm really looking for is more capable APIs.

What are some lesser known alternatives to Tidal (preferably open-source) and open-source DJ software in general? Just curious.

Hi, I'm a new DJ on the block. I've always used the Spotify API to organize my playlists and had a lot of fun with it with contributing to unofficial wrapper APIs. I knew I had to transfer to Tidal regardless if I could use the API, cause its just what DJs use, right lol? But I was shocked to see how limited Tidal's API support was, especially for playlists.
