Jerboa is a app for Lemmy a federated reddit alternative. Jerboa is made by Lemmy's developers and is free open-source software meaning no advertising monetizing or venture capital ever.

Lemmy is similar to sites like Reddit Lobste.rs or Hacker News: you subscribe to forums you're interested in post links and discussions then vote and comment on them. Behind the scenes it is very different; anyone can easily run a server and all these servers are federated (think email) and connected to the same universe called the Fediverse.
