Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

powering an esp32 with batteries
If you look at recharging the device a good charging circuit and low quiescent LDO is needed. Andreas Spieß (popular YouTuber in this domain) compared several developer boards. The outcome is for me to go for „Firebeetle“. A project of mine gives details: https://github.com/Torxgewinde/Firebeetle-2-ESP32-E

Keeping time while in deep sleep possible?
My PIR sensor runs from battery and uses the RTC to estimate battery runtime: https://github.com/Torxgewinde/Firebeetle-2-ESP32-E/blob/main/Firebeetle_DeepSleep.ino

Arduino libraries vs directly writing registers - worth it? (details/debate in comments)
But just because Arduino has terrible APIs like digitalWrite and analogWrite, doesn't prevent you from doing some zero-cost abstractions yourself, you don't have to be extreme about it.
What are some alternatives?
OpenMQTTGateway - MQTT gateway for ESP8266 or ESP32 with bidirectional 433mhz/315mhz/868mhz, Infrared communications, BLE, Bluetooth, beacons detection, mi flora, mi jia, LYWSD02, LYWSD03MMC, Mi Scale, TPMS, BBQ thermometer compatibility & LoRa.
DxCore - Arduino core for AVR DA, DB, DD, EA and future DU-series parts - Microchip's latest and greatest AVRs. Library maintainers: Porting help and adviccee is available.
DFPlayerMini_Fast - Fast and easy to understand Arduino library to use the DFPlayer Mini MP3 module from DFRobot.com. This is a huge improvement (both in terms of execution speed and simplicity) to the standard library provided by DFRobot.com.
Fast - Fast IO compatible with library making for Arduino.
Marlin - Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine.
