You don't mention your use case but the ESP32-CAM gets you an ESP32-based wifi streaming camera for about $10 USD. No app. No account. Surprisingly powerful.
Have they fixed the stability issues yet? When I last looked at ESP32-CAM a couple of years ago, it was so unstable as to be unusable. Have newer versions of software and/or hardware made an improvement?
I don't know. Got one myself a short while ago but have not gotten to trying it out yet. I'd be quite surprised if it hasn't improved over that time though.
esp32-cam is just ok. the quality of the camera is generally very very low. it also can't do h264 meaning that certain integrations like streaming/recording/detecting motion in apple home will require you to do transcodes on some other hardware (which can get expensive).
