Ask HN: Any Modern, Serverless Alternatives to Lobste.rs?

I’ve been a fan of Lobste.rs for its great community and invite-only model. Recently, I’ve been wondering if there are any modern alternatives out there—especially those that use a serverless architecture.

I'm particularly looking for open-source options or any unique takes that embrace scalability and low maintenance through serverless tech.

Anyone seen anything cool or working on something similar? Would love to hear your thoughts!
