I first tried to use growthbook. They had only react support. I thought - I could use the js sdk and work around it. Ok fine. It seemed a bit complicated to use in terms of their UI. Okay fine, I try to find an easier one maybe I can self-host. That way I could even put it behind cloudflare CDN and use caching on it and clever cache-busting when I change values could help propagate changes. Okay fine I have a plan. I ended up going with Flagsmith instead. It was even easier. Perfect.

Project mention: A simple way to explore data through a Tableau-like UI directly in your data app | news.ycombinator.com | 2024-12-30
Contributor to panel-graphic-walker and Panel here.
Its actually primarily a wrapper around graphic-walker https://github.com/Kanaries/graphic-walker as we have optimized the implementation for Panel usage in notebooks and data apps.
Its built on Panel https://panel.holoviz.org/index.html which is "The Powerful Data Exploration & Web App Framework for Python". Its a fully open source and community driven project. Part of the larger HoloViz https://github.com/holoviz/holoviz ecosystem for data visualization.
My motivation for creating the panel-graphic-walker extension is that its one of the most powerful ways in Python to let users interactively, explore large datasets as it can send heavy calculations to the backend instead of transferring all data to the frontend.

- Battle-tested: A team of two frontend devs built an entire EdTech platform (LMS, CMS, and Analytics with telemetry for a web-first 3D engine) using only RushDB - no backend expertise required.
Right now, there’s an SDK for Python and TypeScript, but the REST API provides the same DX.
