ude API routes and client-side hooks/logic. Users can integrate a Fragno library into their application with just a couple of lines of code. This embeds the API routes and lets them immediately use the library’s functionality from the frontend.

A Fragno library integrates end-to-end: type-safe from reactive hook to backend logic. It supports React, Vue, Svelte, Next.js, React Router, Nuxt, SvelteKit, and more.

The need for a full-stack library came up as I was building Recivo (my last Show HN). I wanted to integrate a simple AI/LLM chatbot that could help navigate the dashboard and fill in forms. I wanted to build it so it could integrate not only with my React Router-based app but also with apps built with different full-stack frameworks.

I believe this all could be useful for API-first companies wanting to onboard users quickly, or building frameworks such as Better Auth (which was an inspiration in building this).

It’s early days. I’d love to hear what use cases people come up with. Let me know what you think!

I built Gitvizz to make it easier to understand large nested codebases + completely open source

Instead of scrolling endlessly through files or grepping around, you can just point Gitvizz at a repo and it’ll give you an interactive graph: modules, files, functions, imports — all wired up so you can see how things connect. You can zoom into sub-graphs, follow dependency chains, and even export snapshots or plain-text summaries.

It works with most common stacks (JS/TS, Python) new language support coming soon

Why I made this Whenever I joined a big project or inherited code I didn’t write, I’d always wonder: “What depends on what? How messy is this part really?” Metrics and lists helped a bit, but they never gave me a clear map. So I built Gitvizz to give that “big picture view” at a glan
