We're trying to organize a hackathon, and one of the users has a proof of concept gateway running allowing Red Reader (and other 3rd party apps) to switch to Lemmy with no changes (except for the API url). It's basically providing a reddit-compatible api for lemmy.

And also https://www.reddit.com/...

/u/whupazz is working on a reddit compatible api for lemmy, meaning most 3rd party apps should work with little or no modification. See it working with RedReader already: https://imgur.com/a/IF5HYGz

Follow or help here: https://www.reddit.com/...

Let's get a hackathon going. Maybe it's possible to have a project which allows these apps to work with lemmy. I created a sub on reddit for it: https://www.reddit.com/r/apihackathon/

But maybe that's not the right spot - happy for someone to create a similar community here too.
