Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1803

OK I am a ESP32 novice, I need what this library does, allow the non coders too easily connect an ESP32 to their home Wifi, but damn is this thing large, sure I want to get the local Wifi details , but then I want space to run my own code, fun things like Rest API, MQTT, logic, sensor polling and cleanup, OTA via website. So I took hacked away big chucks of the code I do not need, and yet it still takes 53% of my minimal Spiffs config, seems fat to me for something which only needs to get the users Wifi details, how do I reduce it further?

There is a min branch I made to test this out, but theres not much you can do, the esp library has also grown.
Like you say I cant get it under a certain size. Even removing all strings. Try a different partition scheme, ota and spiffs is alot to ask for woth other libs, you using 4M?

I havent tried removing wifi ap scanning, have to manual enter wifi then..

If you use platformio it has memory profiling

Thank you, will see if I can make any progress with platformio.
