👀 What is this? Why?

Radish is a super fast drop-in replacement of the in memory key-value store redis, built with golang.

Why? Redis recently (Last week, as of Mar 25 2024) changed their license to a dual 'source-available' license - which means that it can't be used for commercial purposes without paying for a license. Everyone hated it. This is a problem for many companies and developers who use redis in their projects.

And, I was kinda bored and wanted to learn golang properly, so I built this.

Should you use this in production? Probably, probably not. It's not battle tested yet, but i (as a single person team) have tried to do my best to make it as reliable as possible.

I even made a cute mascot (Godis crushing Redis)

Annddd all i ask in return is a little ⭐ so that i dont have to rely on twitter for my dopamine hit.

This IS compatible with the existing redis tooling and client libraries! Try it out with some of them.

For eg.

npm i -g redis-cli

127.0.0.1:6379> incr mycounter
(integer) 2
127.0.0.1:6379> set foo bar
OK
127.0.0.1:6379> get foo
bar
127.0.0.1:6379> get bar
