Mesop – Open-source Python UI framework
I’m excited to share about Mesop - a new, open-source Python UI framework that enables Python developers to quickly build delightful web apps in a scalable way. A small team of us at Google have been developing Mesop as an unofficial 20% project for the past few months. A wide range of research and product teams at Google have been using it to rapidly build internal apps and we’ve gotten a lot of positive feedback internally so now we’re looking to get feedback from the open-source community. We think that Mesop provides a unique approach to building web UIs in Python - making it both easy…

In plain words
Mesop is an open-source Python UI framework that allows developers to build web applications using Python. Developed by a team at Google, it is designed for Python developers who want to create scalable web apps without extensive front-end expertise. The framework aims to be both accessible for beginners and flexible enough for customized interfaces across various use cases. It has been tested internally by multiple Google teams for building rapid prototypes and internal applications.

Dropbase – Build internal web apps with just Python2023 · github.com · ▲207Hey HN, I’m Jimmy, co-founder of Dropbase (https://www.dropbase.io). We are an internal tools builder for Python developers. All you have to do is import any Python scripts/libraries, declare UI components, and layer app permissions so you can share them with others. We’re a middle ground between Airplane and Retool—simpler UI creation than Airplane, more code-centered than Retool. UI building is declarative and you can bind Python scripts/functions to UI components. You can write Python scripts/functions using our App Studio with support from a Python Language…
Mountaineer – Webapps in Python and React2024 · github.com · ▲145Hey HN, I’m Pierce. Today I’m open sourcing a beta of Mountaineer, an integrated framework for building webapps in React and Python. I’ve written a good 25+ webapps over the last few years in almost every major framework under the sun. Python and React remain my favorite. They let you get started quickly and grow to scale. But the developer experience of linking these two worlds remains less than optimal: — Sharing typehints and schemas across frontend and backend code — Scattered fetch() calls to template data and modify server objects — Server side rendering / gateway support — Error…
Typeform was too expensive so I built my own forms2025 · ikiform.com · ▲190Hey HN, I'm a solopreneur and run a web design agency. I create open-source apps, but I also work as a freelancer and designer. I was accepting any new freelance project via forms on my agency website. I was using Typeform, but as time went by and more people submitted forms, it got more and more expensive. That time, I thought to use Google Form, but it was way too blocky and looked very unprofessional on my agency website. So I thought to build my own forms for my own usage, and it turns out it almost doubled form submissions and inquiry calls. I was happy, so I thought to build it for…

Talanoa▲346Hi 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…
