* [grpool](https://github.com/ivpusic/grpool) - Lightweight Goroutine pool.
* [pool](https://github.com/go-playground/pool) - Go consumer goroutine pool for easy goroutine handling + time saving.
* [tunny](https://github.com/Jeffail/tunny) - A goroutine pool for golang.

* [statics](https://github.com/go-playground/statics) - Embeds static resources into go files for single binary compilation + works with http.FileSystem + symlinks.
* [generate](https://github.com/go-playground/generate) - runs go generate recursively on a specified path or environment variable and can filter by regex.
