24 alternatives to 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…
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… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Mesop – Open-source Python UI framework launched in 2024; newer entries below may have overtaken it.

Hey 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…

Hey 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…

Hey 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…

Hey HN, We are Winston, Edward, and James, and we built Meka Agent, an open-source framework that lets vision-based LLMs execute tasks directly on a computer, just like a person would. Backstory: In the last few months, we've been building computer-use agents that have been used by various teams for QA testing, but realized that the underlying browsing frameworks aren't quite good enough yet. As such, we've been working on a browsing agent. We achieved 72.7% on WebArena compared to the previous state of the art set by OpenAI's new ChatGPT agent at 65.4%. You can read more about it here:…

Wagtail is a new, open-source Django CMS focused on flexibility and user experience. It was originally built for the Royal College of Art, but now we're able to share it with everyone. See https://github.com/torchbox/wagtail and http://wagtail.io (marketing site) and http://www.rca.ac.uk/ (first big site built on Wagtail) We're really proud of the user interface, and we hope that Wagtail will make it easy for Django developers to build beautiful, modern sites. Feedback very welcome! Tom Dyson, Technical Director at Torchbox (Wagtail developers)

One of the biggest context AI LLMs can get from images is their metadata, but it's extremely underutilized. and while PNG and JPEG both offer metadata, it gets stripped way too easily when sharing and is extremely limited for AI based workflows and offer minimal metadata entries for things that are actually useful. Plus, these formats are ancient (1995 and 1992) - it's about time we get an upgrade for our AI era. Meet MEOW (Metadata-Encoded Optimized Webfile) - an Open Source Image file format which is basically PNG on steroids and what I also like to call the purr-fect file format. Instead…

Hello HN, I'm releasing Hyperdiv (https://hyperdiv.io), a framework for rapidly developing reactive browser UIs in Python, with immediate-mode syntax and using Shoelace (https://shoelace.style) as its built-in component system. This short coding video will give you a good idea of what it is: https://www.youtube.com/watch?v=4XJKfxaqvGE I wrote a brief article about the motivation and approach: https://hyperdiv.io/intro.html Hyperdiv doesn't aim to compete with serious full-stack frameworks. The core aim was to make it easy and fast to…

ChunkHound’s goal is simple: local-first codebase intelligence that helps you pull deep, core-dev-level insights on demand, generate always-up-to-date docs, and scale from small repos to enterprise monorepos — while staying free + open source and provider-agnostic (VoyageAI / OpenAI / Qwen3, Anthropic / OpenAI / Gemini / Grok, and more). I’d love your feedback — and if you have, thank you for being part of the journey!

I started building a couple of years ago because I found no easy existing solution to build Slack bots that can be composed from/organized into plugins. Existing libraries like Bolt make it pretty easy to develop Slack bots, but hard to organize and scale the code base of your bot. I was also missing some crucial features such as scheduling actions for your bot. So I wrote my own framework! I recently rewrote the complete framework to make use of asyncio and the newest Slack SDK Let me know what you think!
