FrameworkKit

What it does

I kept pasting schemas into random online converters and worrying about where the data went. FrameworkKit runs everything client-side: Zod → JSON Schema, JSON → Zod, TS → Zod, OpenAPI → Zod, plus Next.js metadata + tsconfig helpers. Free, no signup. I also wrote guides for Zod 4 changes like the native z.toJSONSchema(). Feedback welcome.

  A tool to visualise Zod validation errors2024 · zod.fyi · ▲17

  I work on code generator that creates TypeScript SDKs from OpenAPI specs and Zod (https://zod.dev/) is a critical building block that I chose to power runtime validation in those SDKs. Depending on the complexity of a Zod schema, the resulting validation error message can contain a wall of JSON text - the serialised issues that were recorded during validation. I wanted to try and create a small tool to help me better visualise and parse these errors. In code and the command line, we do also have the ability to pretty-print the errors but I still wanted a web UI which can let…

  Talanoa▲345

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
