Can You Import Lovable, Replit, or React Apps into Retool?

Updated

Yes. Retool's app builder accepts apps built on Lovable, Replit, and other platforms, as well as React code you've written yourself. You import by uploading a ZIP file or syncing with GitHub, and the imported app then runs inside your Retool environment with its authentication, access controls, and audit logging applied. This fits teams that already have a working prototype and want to keep it rather than rebuild from scratch.

What the import path actually covers

Retool describes the import flow as a way to "deploy apps built in Lovable, Replit, and other platforms" by uploading a ZIP or syncing with GitHub. The same page frames this under a "Secure your vibe-coded apps" heading, which tells you the intended audience: apps generated quickly by AI tools or low-code builders that now need production-grade handling.

Two things follow from that framing:

  • The import is a deployment step, not a rewrite. You bring the built artifact in; you don't re-describe the app to Retool's AI builder.
  • Governance is applied at the environment level. Because the app lands in your Retool workspace, the security posture described for Retool apps — auth, access controls, audit logging — is what the imported app inherits.

Importing vs. building with AI vs. importing React

Retool presents three distinct ways to get an app into the platform. They suit different starting points, so pick by what you already have:

Your situation Path What you provide
You have a finished app from Lovable, Replit, or similar Import A ZIP file or a GitHub sync
You have a prompt and data sources, no app yet AI app builder A description of the app; use @ to include data
You have React code and want agent/CLI tooling Build with AI agents Use the MCP server or CLI, then deploy in Retool

If your app already exists and works, import is the shortest route. If you're starting from a spec, the AI app builder generates "a full, production-ready app" from a prompt. The MCP/CLI path is for teams that want to drive app creation from their own tooling and then deploy into the governed environment.

What happens to security after import

This is the part that usually decides the question. Retool states that what you build is "enterprise-grade from the start — no rebuild, no audit scramble, no IT veto," and that deployment comes with auth, access controls, and audit logging already in place.

For an imported app, the practical reading is:

  1. Authentication is handled by your Retool environment rather than bolted on afterward.
  2. Access control follows your existing permissions — Retool says app data access "is governed by your existing permissions—no extra configuration required."
  3. Audit logging is present because the app runs inside Retool, not as a standalone deployment.

The claim worth verifying in your own environment is the permissions inheritance: confirm that the data sources your imported app calls are reachable under the same permission model your team already uses.

Connecting imported apps to production data

An imported front end is only useful if it can reach real data. Retool says every app connects directly to production data sources, and points to a full integrations list covering databases, APIs, and LLMs. The site does not enumerate every connector on the page referenced here, so check the integrations list for your specific database or API before committing.

A sensible sequence for a first import:

  1. Confirm your target data source appears in Retool's integrations list.
  2. Import the app via ZIP or GitHub sync.
  3. Point the app at the data source and verify queries return under your existing permissions.
  4. Check that auth and audit logging behave as expected in a non-production workspace before promoting.

When import is the right call — and when it isn't

Import makes sense if you have a working app from Lovable, Replit, or a React codebase, and the blocker is governance rather than functionality. You keep the UI you built and gain the security and operational layer.

Import may not be the best fit if the app is still a rough prototype whose logic you expect to change substantially — in that case the AI app builder, which generates from a prompt and connects to data directly, may get you to a maintainable app faster than importing and then reworking it.

Either way, the decision hinges on one check you can do early: whether your data sources are supported and whether your existing permissions carry over cleanly. Settle that first, and the rest of the import is a deployment step.
