The Replit approach.
Replit Agent creates and edits applications from natural-language instructions in Replit’s development environment, with publishing and infrastructure services available.
Start with AI. Build on a Python foundation.
Use Reflex Build to start with AI and continue in a Python application framework. Keep interface behavior and backend business logic in the same language, with managed hosting or self-hosting for your framework app.
Build the application your team needs.
Make your business logic part of the application foundation.
Bring it together with Reflex.
Generate and refine Reflex applications with Build, backed by the Reflex Python framework. An opinionated full-stack Python framework for interface components, state, and backend events.
Keep the work you can build on.
Carry forward the product requirements, data contracts, and tested Python functions from your existing project. Use them to define the first Reflex workflow and its acceptance checks.
Compare the details.
Compare what you can build, how you can extend it, and where it can run. Explore the sources for each product.

| Decision | Replit | Reflex |
|---|---|---|
| AI development | Agent plans, writes, and tests projects from prompts. | Generate and refine Reflex applications with Build, backed by the Reflex Python framework. |
| Application foundation | A development platform supporting different project types and technologies. | An opinionated full-stack Python framework for interface components, state, and backend events. |
| Deployment model | Offers integrated publishing and infrastructure services. | Choose managed hosting or self-host the framework application. |
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 purchasing workflow your team can maintain.
Capture the workflow
Use two purchase requests of $250 and $1,500. Define a finance review rule for amounts over $1,000.
Build the first version
Describe the queue, request form, and review flow in Reflex Build. Inspect the generated Python logic.
Connect the services
Implement the approval rule on the server and connect a staging purchasing API with scoped credentials.
Review and release
Verify the $1,500 request routes to finance. Test permissions and duplicate submissions before choosing the deployment environment.
What a passing pilot looks like
The $1,500 request routes to finance, the $250 request follows the agreed standard path, and each action is authorized and recorded exactly once.
Make the move one workflow at a time.
A clear first project. A foundation you can extend.
Moving a Replit project to Reflex is an application migration, not a prompt import. Inventory its framework, storage, identity, and hosting dependencies before choosing what to reuse.
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 Replit?
Use Reflex Build to start with AI and continue in a Python application framework. Keep interface behavior and backend business logic in the same language, with managed hosting or self-hosting for your framework app.
Does moving to Reflex automatically import a Replit app?
No. Reuse requirements, service contracts, and suitable Python code, then rebuild the interface and state in Reflex. Validate behavior against the current app.
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?
The $1,500 request routes to finance, the $250 request follows the agreed standard path, and each action is authorized and recorded exactly once.
Bring one workflow. Build a useful first version.
