There's also two "open source" systems - https://loopkit.github.io/loopdocs/ - https://openaps.org/

Tidepool is also trying to take the loop project and get a version of it FDA approved.

Both of the open source projects require you to do the work and actively take control of your setup (a cgm plus pump plus phone). They have really nice support communities. I would never go back to not using Loop.
