Project mention: Show HN: Next.js-like Python web framework, built for Htmx with FastAPI | news.ycombinator.com | 2025-10-01
Would be cool if it was opiniated with ready to use and interactive components like in FastUI (https://github.com/pydantic/FastUI)
If you do this, i'll use it. But maybe that's not the goal?
That’s how I like to use them framework to quickly bootstrap a project in Python only.
I've started working on a FastAPI with HTMX wrapper also 4 days ago, it's not as advanced as your projects tho. There's not much there yet, but here's the link: https://github.com/lakonguina/devanture

Kokoro-FastAPI
Dockerized FastAPI wrapper for Kokoro-82M text-to-speech model w/CPU ONNX and NVIDIA GPU PyTorch support, handling, and auto-stitching
Project mention: Microsoft VibeVoice: A Frontier Open-Source Text-to-Speech Model | news.ycombinator.com | 2025-09-03I'm using Kokoro via https://github.com/remsky/Kokoro-FastAPI. It has a `generate_audio_from_phonemes()` endpoint that I'm sure maps to the Kokoro library if you want to use it directly.
My usage is for Chinese, but the phonemes it generated looked very much like IPA.

Project mention: Replacing a $3000/mo Heroku bill with a $55/mo server | news.ycombinator.com | 2025-10-21
https://devpu.sh/ is another alternative, it has a nice UI built with Hypermedia (HTMX).
I am building https://github.com/openrundev/openrun/. Main difference is that OpenRun has a declarative interface, no need for manual CLI commands or UI operations to manage apps. Another difference is that OpenRun is implemented as a proxy, it does not depend on Traefik/Nginx etc. This allows OpenRun to implement features like scaling down to zero, RBAC access control for app access, audit logs etc.
Downside with OpenRun is that is does not plan to support deploying pre-packaged apps, no Docker compose support. Streamlit/Gradio/FastHTML/Shiny/NiceGUI apps for teams are the target use case. Coolify has the best support and catalog of pre-packaged apps.
