Author here: I use https://www.hevyapp.com/ on the free plan. It has everything you need and I really enjoy the social component. I have a few friends using the app as well, and its fun to see what others are lifting and challenge yourself to beat them.
https://synthql.dev: An alternative to PostgREST focused on the React-Node-PG stack. Main advantage right now is it gives you end to end type safety: you can write type-safe queries straight from your component that directly access your database.
Why SynthQL? My experience working for +10 years on enterprise SaaS is that a quite often you just want a database and a way to fetch data from it. Backends will quite often get in the way adding abstractions and layers upon layers of transformation between DB objects to domain objects to DTOs.
If you ever feel like you just want to talk to the database directly, give SynthQL a try :)
An open-source, type-safe http client to your postgresql database. It let's you access your database directly from your react components. It's fast, safe and performant. Think Graphql but you don't need to implement resolvers, it's all generated from your database schema.
If this sounds interesting to you, ping me (email on my profile) :)
