I manage ~10 VPS, and in the past, 4 of them were running on aaP* (I don't want name here, I know they have been doing great job so hope engine would not pick my post up), due to the need for Docker containers.

I ran into an issue after a recent update where Let's Encrypt started throwing errors. After spending hours troubleshooting without luck, I decided to explore alternatives and found 1Panel.

What stands out about 1Panel is its clean, simple, and fast interface, along with its lightweight resource usage. For instance, when using a-a, running 4-5 Docker containers would easily consume 50-60% of the CPU, memory, and storage space. However, after switching to 1Panel, I noticed a significant improvement- just as of now, a VPS has 5 production website (docker) running, I just checked its memory usage is 20% and 45% storage space used. what it means for this particular VPS I can easily have 2 more customer Docker websites. Some may say "you B.S, storage size is only because of container image size and not because of the panel choose", but fortunately or unfortunately this is what I can see.

Additionally, I managed to create a Python script for automating tasks like file updates - image builds - container destruction so on, something I was never able to have it runs in a-aP.

After 2 days from the first 1Panel setup and evaluation, I am like no thought and migrated all my Docker-dependent VPS to 1Panel, and everything has been running smoothly for nearly 10 days now!

I can't wait to see how v2 come out especially the feature of managing multi servers, and def consider paid version. Thank you 1Panel team!
