React vs Streamlit
Choosing between React and Streamlit depends on your project requirements, team expertise, and target platform. React is ideal for interactive single-page applications, complex dashboards, and component-heavy UIs, while Streamlit excels at data dashboards, CSV explorers, ML demos, and internal analytics tools. Both are fully supported in LoomCode AI with live preview and one-click deployment.

Here is what happens when you give the same prompt to React and Streamlit in LoomCode AI:
Prompt
Build a contact directory that stores names, emails, and phone numbers with search and category filtersReact Output
React generates a client-side app with React, handling data entry, storage, and filtered retrieval entirely in the browser with state management and responsive Tailwind UI.
Streamlit Output
Streamlit takes a different approach: processing data in Python with Streamlit and Pandas and rendering controls with Streamlit's widget system. Same prompt, fundamentally different architecture.
When to Choose React
React powers millions of production applications from startups to Fortune 500 companies. Its component model, hooks system, and one-way data flow make it the go-to choice for building interactive user interfaces that scale.
- Component-based architecture makes complex UIs manageable and reusable
- Massive ecosystem with thousands of production-ready libraries
- Virtual DOM ensures optimal rendering performance even for data-heavy apps
- First-class TypeScript support with excellent type inference
- Largest developer community means abundant resources and quick problem-solving
When to Choose Streamlit
Streamlit turns Python scripts into interactive web applications. Used by data teams at companies like Snowflake, it eliminates the frontend barrier for data scientists who need to share dashboards, tools, and ML demos.
- Interactive widgets (sliders, dropdowns, file uploads) with zero frontend code
- Built-in charting and data display components for instant data visualization
- Automatic reactive updates — change a widget and the entire app refreshes
- Native file upload and download support for data-driven workflows
- Single Python file deployment — no HTML, CSS, or JavaScript needed
The Verdict
If you need interactive single-page applications, complex dashboards, and component-heavy UIs, React is the stronger choice with its component-based architecture makes complex uis manageable and reusable. If your project requires data dashboards, CSV explorers, ML demos, and internal analytics tools, Streamlit's interactive widgets (sliders, dropdowns, file uploads) with zero frontend code gives it the edge. With LoomCode AI, you can try both in seconds — describe your app idea and compare the generated code side by side.

Frequently Asked Questions
Should I use React or Streamlit for my project?
The right choice depends on your project requirements. React is ideal for interactive single-page applications, complex dashboards, and component-heavy UIs. Streamlit excels at data dashboards, CSV explorers, ML demos, and internal analytics tools. If you're building different types of applications, consider team expertise and learning curve — React has a intermediate learning curve while Streamlit is beginner. With LoomCode AI, you can generate working code in both frameworks and compare the output side by side.
Can I switch between React and Streamlit in LoomCode AI?
Yes. LoomCode AI supports both React and Streamlit in the same session. You can describe your app idea once and generate it in each framework, then compare the results. Switch frameworks at any time — no need to start over. Both support live preview and one-click deployment.
Which framework generates better code with AI?
Both React and Streamlit produce high-quality AI-generated code in LoomCode AI. React tends to leverage its component-based architecture makes complex uis manageable and reusable, while Streamlit benefits from interactive widgets (sliders, dropdowns, file uploads) with zero frontend code. The best output depends on your prompt — be specific about your requirements. Try the same prompt in both frameworks to see which fits your use case better.
Is React or Streamlit easier to learn?
React has a intermediate learning curve, and Streamlit has a beginner learning curve. Streamlit is generally considered more approachable. Using LoomCode AI to generate working examples in either framework can accelerate your learning — you'll see real, runnable code that you can modify and experiment with.
