The Cursor approach.
Cursor provides AI coding tools, including agents that work with project files and development commands. Your repository determines the framework and runtime.
A Python application foundation for your AI coding workflow.
Give your Python team a clear path from editor to application with Reflex. Develop UI components, state, and backend behavior together, then run the app on managed hosting or infrastructure you control.
Build the application your team needs.
Build in your editor. Ship with a coherent app framework.
Bring it together with Reflex.
A Python application framework and optional Build and hosting services. Brings UI authoring and backend interactions into one Python framework.
Keep the work you can build on.
Keep Cursor as your development environment and build a Reflex app inside it. Use the framework’s documented components and event model to guide implementation and review.
Compare the details.
Compare what you can build, how you can extend it, and where it can run. Explore the sources for each product.

Know which part of Reflex you need.
Framework, AI development, hosting, and enterprise services have different responsibilities and entitlements.
Open-source framework
The Apache 2.0 Python framework is available independently of Build and managed hosting. Your app still depends on Reflex and its other packages.
Reflex Build
The AI development product generates and edits framework-based apps. Usage, private projects, repository access, and export entitlements belong to your plan.
Hosting and App Management
Managed deployment is an operating service. You can also self-host a framework app, providing its frontend, Python backend, configuration, and maintenance.
Enterprise
Enterprise packages and services have separate entitlements. Workspace SSO is distinct from app-user authentication. Authorization, auditing, and private deployment need configuration and an agreed operating plan.
Start with one workflow.
A focused pilot lets you validate the interface, business rules, and operating model before a wider rollout. The example below uses synthetic data.
Build a service operations workspace in your editor.
Choose one action
Two service tickets are open. TKT-101 needs an owner before it can move to in progress.
Build the screens
Use Cursor to develop a Reflex ticket list, detail page, and assignment form.
Connect the backend
Validate allowed status changes in a Python handler and persist them to the staging service.
Review the journey
Check rejected transitions, saved assignments, and failed API calls. Review generated code before releasing the workflow.
What a passing pilot looks like
TKT-101 cannot advance without an owner. Authorized updates persist, and a service failure leaves the user with a clear retry path.
Make the move one workflow at a time.
A clear first project. A foundation you can extend.
Changing editors does not create an application architecture. Define the Reflex state model, service boundaries, tests, and operating responsibilities as part of the first workflow.
Plan application authentication, authorization, monitoring, and maintenance with your team. The framework, Reflex Build, managed hosting, and enterprise services have separate responsibilities and entitlements.
Questions before you choose.
The practical details, before you make a move.
Why build with Reflex instead of Cursor?
Give your Python team a clear path from editor to application with Reflex. Develop UI components, state, and backend behavior together, then run the app on managed hosting or infrastructure you control.
Do we have to leave Cursor to use Reflex?
No. You can develop a Reflex app in Cursor. Use Reflex Build if you want its integrated AI app development workflow, or work directly with the open-source framework in your editor.
Can we choose where the Reflex app runs?
Yes. Use managed Reflex hosting or self-host the framework’s frontend and Python backend. Self-hosting includes responsibility for configuration, secrets, scaling, and operations.
How should we validate the first release?
TKT-101 cannot advance without an owner. Authorized updates persist, and a service failure leaves the user with a clear retry path.
Bring one workflow. Build a useful first version.
Start in Build, or work with our team to scope the application and the way it will run.
