Glue4 is a Redux extension that handles your back end concerns

In plain words

Glue4 is a Redux extension that eliminates backend setup for web applications. It provides built-in authentication and state persistence through a single npm install, removing the need to independently choose and manage databases, hosting, and backend infrastructure. Designed for developers building apps that require basic backend functionality, Glue4 handles authentication and data persistence out of the box, letting developers focus on frontend development without dealing with cloud hosting complexities.

In the maker’s words, at launch

We built Glue4 to scratch our own itch: whenever we start building an app, there’s all these different layers that need to be pieced together with subtle gotchas (auth, backend, DB, where to host, etc). The vast majority of the apps we build don’t really need anything beyond state persistence and authentication. And that’s what Glue4 abstracts away: having to host our own backend, pick our own DB, figure out the querying language/ORM and then host & maintain them all somewhere “in the cloud”. All you need to do is run a single npm install command and you get Auth + state persistence in the backend out of the box. Fire away with critiques/questions/anything really :)

  Hey HN! Happy to finally launch Stack. We made it because we like to put apps into production quickly, and authentication & user management was taking up way too much time. We have components like and that automatically adapt to whatever theme & design system you're using. Check the blog post to see the example with Radix UI and Joy UI. Also, there's an admin dashboard for monitoring and editing accounts. Stack is 100% AGPL/MIT-licensed, so you can self-host it. Cheers!
