In plain words
React Proto is a design and prototyping tool for React applications that helps developers and designers plan components, their hierarchy, and state management before coding. The tool aims to reduce refactoring and unnecessary code as projects scale by enabling developers to define how components interact through props and state from the start. It focuses on creating organized, intentional code structures during the early development phase.

React Proto aims to give developers and designers the tools necessary for creating clean, organized, and intentional code from the beginning of the development process.

I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

Talanoa▲341Hi 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…

Retool▲640Hi all, founder @ Retool here. We initially launched Retool on HN five years ago: https://news.ycombinator.com/item?id=14515494. The feedback was extraordinarily helpful then (e.g. we launched source control, on-prem, etc. based on HN comments), and we’re grateful for all of it. Today, we’re excited to get HN’s thoughts on one of our new products: Retool Mobile. It lets you build and deploy mobile apps in minutes, not days. The idea is there is a large class of line-of-business mobile apps, and the process of getting a simple form + button on a mobile device, in a native app,…
