The status of the project.

[alexey-milovidov]

The library is very impressive as it looks like a pareto frontier.

But I see there are no updates in about half a year.
E.g. trivial fix for UBSan did not get merged: #33

It makes me wondering about the perspectives of this project.

[alexey-milovidov]

After one year we can conclude that this project is abandoned.

[alexey-milovidov]

After two years, the conclusion holds.

Yes, I already checked - I want to try integrating it, but the current obstacle - is the need to convert assembly files in the Go Asm dialect.

Back in 2017, Lizard 1.0 filled a niche between LZ4 and zstd in terms of compression ratio, as well as compression and decompression speed. However, based on benchmarks conducted in 2025 (shared on main page), both LZ4 and zstd have made substantial advancements, particularly in compression and decompression speed, leaving Lizard outdated and effectively obsolete.

This test result on Intel is a bit different. In relation to zstd, for example, lizard is much faster.
