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.

Compression algorithms for HTTP packets
This GitHub repo might have something that works https://github.com/pfalcon/uzlib , according to the author, the compression ratio isn't very high

Using TAR files in ESP32 with SD applications for easy multiple file transfers
I am engineering a watch to play home videos of my children on my wrist - my Reflections project. I need an easy way to move multiple files from a Cloud based service to the watch. tar) and GZip are widely used standards to build and compress an archive of binary (for example, movies and sound files) and text (for example, JSON encoded procedural scripting command) files. Using tar I simplify my code to move one tar file instead of multiple individual files. The ESP32-targz library combines uzlib and TinyUntar to decompress and inflate tar files and works well with Arduino IDE 1.8.13, ESP32, and an SD card. This is my developer’s journal of the problems that I encountered and the work-arounds I used.

What are some alternatives?
ESP32-targz - 🗜️ An Arduino library to unpack/uncompress tar, gz, and tar.gz files on ESP32 and ESP8266
zlib-ng - zlib replacement with optimizations for "next generation" systems.
sent - a simple plaintext presentation tool
Stm32-FatFs-Gzip - This project offers a simplified compressor that produces Gzip-compatible output with small resources for microcontrollers and edge computers. He uses the very basic LZ77 compression algorithm and static Deflate Huffman tree encoding to compress / decompress data into Gzip files.
Owin.Compression - Compression (Deflate / GZip) module for Microsoft OWIN filesystem pipeline. Works with Selfhost and also on AspNetCore.
eiwd - iwd without dbus -- maintained fork of original dylanaraps/eiwd
pycopy - Pycopy - a minimalist and memory-efficient Python dialect. Good for desktop, cloud, constrained systems, microcontrollers, and just everything.
flate2-rs - DEFLATE, gzip, and zlib bindings for Rust
nflate - Naive implementation of DEFLATE in C for decompressing gzip files (RFC 1951, RFC 1952).
castget - A simple, command-line based RSS enclosure downloader, primarily intended for automatic, unattended downloading of podcasts.
jdeflate - DEFLATE compressor/decompressor implementation
