Hyperdiv – Reactive, immediate-mode web UI framework for Python▲170
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…

MonkeyPatch – Cheap, fast and predictable LLM functions in Python▲95
Hi HN, Jack here! I'm one of the creators of MonkeyPatch, an easy tool that helps you build LLM-powered functions and apps that get cheaper and faster the more you use them. For example, if you need to classify PDFs, extract product feedback from tweets, or auto-generate synthetic data, you can spin up an LLM-powered Python function in <5 minutes to power your application. Unlike existing LLM clients, these functions generate well-typed outputs with guardrails to mitigate unexpected behavior. After about 200-300 calls, these functions will begin to get cheaper and faster. We've seen 8-10x…

Modshim – A new alternative to monkey-patching in Python▲109
I've invented a new alternative to forking / vendoring / monkey-patching packages in Python. It's a bit like OverlayFS for Python modules - it allows you write modifications for a target module (lower) in a new module (upper), and have these combined in a new virtual module (mount). It works by rewriting imports using AST transformations, then running both the lower and upper module's code in the new Python module. This prevents polluting the global namespace when monkey-patching, and means if you want to make changes to a third-party package, you don't have to take on the…

Strict interfaces and dep management for Python, written in Rust▲68
Tach is a pip package that lets you define module boundaries, automatically detect all cross-module dependencies, and then validate and enforce those dependencies. It also supports strict interfaces for modules by overloading `__all__`. The core static analysis is done in Rust, so all Tach commands run quickly. The goal of Tach is to help eng teams maintain velocity while scaling quickly, something we've seen break down a number of times. Give it a try!
