Reflex is an AI app builder that lets you create production-ready web apps entirely in Python, powered by its own open-source framework. Just connect your data and enter a prompt—it builds full-stack apps that work with any data source, API, or Python package.
Last year we launched Reflex as an open-source framework that lets you build full-stack web apps in pure Python - no JavaScript required. Since then, over 1M apps have been created, it’s used by 30% of the Fortune 500, and the project has grown to 27K+ GitHub stars.
Today we’re taking the next big step with Reflex Build, our new AI app builder built on top of the Reflex framework.
Reflex Build lets you go from idea → production-grade web app entirely through prompting and Python. You describe what you want, connect your data or APIs, and Reflex generates a working app that you can fully customize. It’s designed for teams who want the speed of prompting, but also the power and control of real code.
Here’s what you can do:
Prompt to App: Build your app through prompting, and Reflex generates it in Python.
Connect to Anything: Databricks, Supabase, LLMs, Auth Providers, REST APIs, or any Python package.
Extend with Code: You can view and modify the generated Python, and add custom logic and components
Deploy Instantly: One command (reflex deploy) ships your app to production, with hosting and scaling handled automatically.
Enterprise-Ready: Add your own auth and deploy to your company's existing infrastructure
Whether you’re prototyping a quick idea or rolling out an internal tool to production, Reflex lets you stay entirely in Python from start to finish.
Would love your thoughts, feedback, and to see what you build!

Really impressive engineering behind Reflex. Building full-stack, production-grade apps entirely in Python is indeed exciting! Congratulations!
Congrats on being the Product of the Day!
The open-source foundation and “prompt-to-production” workflow make this a true gem for Python developers.
Would you like to share with the PH community what inspired the architecture behind the Reflex framework?
Curious if the generated apps can plug directly into cloud providers like AWS or GCP or if Reflex has its own hosting solution planned? Grats on the launch!!
Congrats Nikhil and team! The community around the product feels active and I saw the documentation on the website... very well put and miles ahead of most no/low-code builders. :)
It looks incredibly promising. I've spent months learning React for app building but this seems to skip all that. Writing everything in Python just feels so natural and efficient.
I can't believe how clean the Reflex approach is, prompt in, production app out. As a data person, I can finally deploy my models easily. This is going to save me tons of time.
This is really cool. I've always wanted to create apps without dealing with frontend frameworks. It seems like the bridge between Python scripting and real web app. So much potential here.
It sounds like a dream for indie developers like me. It saves so much time while giving full control. I can see this being a huge boost for building MVPs and prototypes fast.
I'm genuinely curious to see how it handles scalability. The concept is powerful, prompt to production-ready apps in Python. It feels like the next natural step for AI-powered coding tools.
I just read about it and I'm fascinated. Being able to use any Python package directly in a web app is massive. It's like simplifying full-stack development to a single language.
Wow, this is great for Python devs like me. It lets creativity flow without worrying about frontend stuff. I love how it bridges data science and web development seamlessly.
I've been building small dashboards lately and it might save me hours. Writing everything in Python instead of switching between React and Flask is just brilliant. This could become my go-to framework.
Honestly, it feels like magic. The concept of typing a prompt and getting a deployable app still sound unreal. I'm really curious how it integrates with external APIs and data sources.
I tried recently and I'm amazed by how fast it builds working apps. No need to juggle JS or frameworks, just pure Python. Perfect for rapid prototyping or even production apps.
As a python enthusiast, this idea blows my mind. The fact that it handles front-end and backend effortlessly is wild. It's like Streamlit but more production-ready, love it already!
I'm really impressed by how it turns plain Python prompts into full-stack apps. As someone who loves coding but hates setup, this is a dream. Can't wait to try it on my data!
I've been exploring it lately, it feels like magic building production apps in pure Python. No messy JS, just data and prompts. As a Python enthusiast, this is exactly what I needed to turn ideas into full-stack apps effortlessly!
Congrats Nikhil and team! Building frontend and backend all in Python is huge, and Reflex Build feels like the sweet spot of prompting plus real code. Love the connectors and reflex deploy. Any public examples of complex apps, like multi tenant auth or data dashboards?
