I wrote WhoaLife ( https://github.com/vonnieda/WhoaLife ) when OhLife shut down. It's self hosted for privacy and designed for Heroku Free Tier. Takes about 15 minutes and no code to deploy.

I've been using it since OhLife shut down and it completely fills the gap for me.

I recently modernized the code a bit, ported it from Mongo to Postgres and improved the selection of the random entry that is sent to you, but I haven't pushed those changes yet. They'll go out in the next week or so.
