The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Is porting the ATtiny13 even feasible?
I've done some digging (mainly into wiring.c) and I noticed a slight problem: the micro core used for the ATtiny13/ATtiny13A doesn't provide the timer0_millis variable. The millis() implementation only has some inline assembly which I don't fully understand.

Arduino Uno Bootloader flash Issues
I used MiniCore with some help from this ARTICLE and was able to flash my uno but encountered some more problems

definitive guide on programming the SMD ATmega328 or ATmega32u4?
Once you buy the programmer, install the drivers on your computer. Your Arduino IDE will also need the correct "boards" installed to program all the different microcontrollers. This is done through the "Boards Manager." Use the MiniCore GitHub page to install the Atmega328.
- Having trouble communicating with a CP2102 IC on a custom board. Simplicity Studio says it is not recognised properly even though it does show up. Tried replacing drivers with Zadig, no change. Perhaps the schematic is wrong?

ATMEGA328PB-MU TWI Issue
To be on the safe side you may want to install a 3rd party "Arduino core" specific for this chip, in case some pinouts or constants were changed compared to to earlier ATmega328 chips. Google gave me this: https://github.com/MCUdude/MiniCore ; others may exist.

Burning a bootloader onto an ATmega328p.
If you do want to use the Arduino libraries and Arduino IDE as normal you need to install MCDude's MiniCore which is an implementation of Arduino that lets you work directly with the chips (i.e. the "board" in the Arduino IDE is the chip directly). In the link above you can find amongst others install instructions and the maps of the chip pins to Arduino pins (which you need to know which microcontroller pin corresponds to which Arduino pin number when you do things like digitalWrite).

Running ATMEGA328P at 27mhz?
You'd need to create your own board definition as the default install only handles 16MHz. MCUdude's MiniCore core shows how this could be done: https://github.com/MCUdude/MiniCore
What are some alternatives?
When comparing MicroCore and MiniCore you can also consider the following projects:
ATtiny13-TinyUPS - Uninterruptible Power Supply
MightyCore - Arduino hardware package for ATmega1284, ATmega644, ATmega324, ATmega324PB, ATmega164, ATmega32, ATmega16 and ATmega8535
