Awesome-go list with stars. Automatically updated

About

This repository is a clone of Awesome Go but with stars. All repositories are still sorted alphabetically.

Why?

Some of the viewers might be against this idea because "stars don't mean anything" or "stars != code quality". Yet stars are about numbers, and numbers talk for themselves. First of all, stars may help some newcomers who are not familiar with %%programming_language%% ecosystem and want to find some good framework for the first project. This list will help them to find a few popular web-frameworks, libraries or tools for a quick start. Secondly, people like me might often use a such list of projects to find something trending or they just want to find similar libraries to run benchmarks.

How?

This repository is updated every %%interval%% by the script which is/will be run by scheduler.
