You can selfhost some but mines are not for english content so can't recommand any

Edit: as requested in comment (for the froggies) Before i list, basically any addons available at gitlab/github are self hostable (they are quite a few), just make sure addon is compatible with your debrid service, your prefered PT, streaming site and content you want to watch (for clean mapping)

• Wastream (DDL and streaming site)
• Comet (Private and open tracker) actually they should be a version for english content and probably other languages
• streamfusion (private and open tracker)

Something i have never used is aiostream (allow to aggregate addon and lots of customisation), seems to suit a lot of people. It also has a community Addon marketplace, so you may discover addons you don't know about, check if those are also available as selfhost (probably will)
