Reflex is the open-source framework empowering Python developers to build web apps faster. Build both your frontend and backend in a single language, Python (pip install reflex), with no JavaScript or web development experience required. Our mission is to simplify web development by creating an ecosystem of open-source tools and hosted services that enable Python developers to build web apps faster without compromising on customizability, flexibility, or performance.

Build web apps in pure Python (no Javascript required) and deploy with a single command. Reflex Cloud includes a dashboard to manage our apps, custom domains, flexible memory and CPU options, One-Click Auth, website analytics, On Premise Hosting and more.

Hi PH! I’m Nikhil, founder of Reflex (https://reflex.dev) We released our open-source framework (https://github.com/reflex-dev/re...) with a goal to simplify web development. Anyone who knows Python should be able to turn their ideas into web apps without Javascript. Today thousands of teams use Reflex for their data/AI apps, internal tools, and customer-facing web apps. Now we're launching Reflex Cloud, a platform for deploying and managing Reflex apps. With Reflex Cloud we're extending that same simplicity to hosting. Just `reflex deploy`, and in a few minutes your app will be live to share with the world. Our free tier lets you deploy your first app at no cost. Once you deploy, you can log in to your app dashboard to see the status of your apps, the resources they're using, and application logs all in one place. We also have Pro, Team, and Enterprise tiers to take your app from prototype to production. Reflex Pro lets you take your app from a prototype to a production app with: - Custom Domains: Use your own domain for your app - Larger Apps: Increased memory and CPU options, and deploy to multiple regions - Add Collaborators: Add team members to your project We're previewing team and enterprise plans with advanced features like: - One-Click Auth: Add Github, Google, or other OAuth providers to your app with no code - Full Analytics: Comprehensive insight into your app's performance and usage - On Premise Hosting: Run Reflex Cloud on your own infrastructure With our open source framework and our cloud hosting, we're providing a unified platform to turn your ideas into deployed apps that you can share with your company, or the world! Goals of Reflex: 1. 🐍 Pure Python: Use one language for your web app. 2. 💡 Easy to get started: Build your ideas easily without needing web development experience. 3. ⚡ Full flexibility: Web apps should match the customizability and performance of traditional web frameworks. 4. 🔋 Batteries included: Handle the full-stack from the frontend, to the backend, to deployment. Deploy with a single `reflex deploy` command. 5. 🥞 Empower Your Team: Instead of having separate dedicated engineers for frontend, backend, and infra, every engineer can now understand and work across the whole stack. If your team uses Python, I'd love to learn more about your experience building data and web apps!

@picklelo Love the concept, Nikhil! Quick question: Can AI models generate Reflex apps (frontend + backend) efficiently? I’m a big fan of react and shadcn UI because claude 3.5 handle them so well. If claude is as knowledgeable in reflex as it is in shadcn then why not we just max out Python for everything!

@picklelo @tonyabracadabra Yes Claude is fairly good are reflex our search on our website has an ai feature which can also answer questions and provide code snippets about reflex

@tonyabracadabra Hey Tony! More recent AI models have been trained on Reflex, and tools like Cursor are able to index the Reflex docs to generate code. But we're also building AI features into Reflex itself. You can see an experimental version here: https://flexgen.reflex.run We're focusing a lot more of our efforts in the upcoming months on building out AI agents that can generate Reflex apps - so you can build apps quickly while staying in Python, making it easier to integrate with your existing code.

@picklelo oh great to see that!!

@picklelo So cool! The ability for non-developers to contribute to app creation is a significant step forward in fostering collaboration between teams. Quite impressive :)

Go reflex! We've been using reflex since early 2024, and now we got both B2B and B2C reflex apps in production. Can't say how happy I am that I don't have to switch between python and javascript on a daily basis, and can simply stay on python for my whole tech stack 🙏🏼 Until today we always self hosted our apps, and will keep doing that in the near future for clients with sensitive data. But can't wait to speed up our deployment setup 10x with reflex cloud 💙

@paul_from_dentro Thanks Paul!

Congrats on the launch, @tom_gotsman @picklelo @alekpetuskey @masenf @simonmyoung Startup Pitch Decks Do you offer auto-scaling as part of the Pro plan?

@ashitvora Currently you have to manually scale your apps - but we have autoscaling in our roadmap and will offer that soon!

you should be able to choose machine/vm types on any deploy/re-deploy. As for auto scaling, this is something the team would look into.

A great way for people familiar with Python to develop web apps. All our revenue was generated from Reflex-based apps. Kudos to the amazing team!

I've been using Reflex for a few weeks now, and it has greatly simplified my previous combination of dash/flask/FastAPI into one consolidated framework. It's infinitely faster, more easily customized, and has a great group of maintainers that address issues very quickly. Super happy that I found it!

Congratulations on the well-deserved launch on Product Hunt! Reflex's ease of use and innovative features make it a standout. Looking forward to seeing it thrive.
