# What is LumiDevKit?

LumiDevKit is a set of free browser tools for Bubble.io developers. You give it an export from your Bubble app, and it turns that export into things you can actually read: a database diagram, a workflow trace, a reusable-element tree, a design system, an audit.

It is free, it requires a signup, and there is nothing to install.

## The mental model

Every tool follows the same four beats:

**export → upload → explore → export back out**

You get a file out of Bubble, drop it on a tool, click around, and take something useful away: a diagram to share, a SQL schema, a design system document, a list of performance problems.

The one thing worth knowing up front is that the parsing happens in your browser. Your export is not sent to a server to be processed. The single exception is if you deliberately save a schema to your account, which is covered in [privacy and your data](/docs/privacy-and-your-data).

## The tools

## Two ways to start

**You already have a Bubble app.** Get its export and pick a tool. Start with [get your app export out of Bubble](/docs/export-your-bubble-app), then [which file does each tool need?](/docs/which-export-does-each-tool-need).

**You have an idea, not an app.** You do not need Bubble at all. Describe your idea to ChatGPT or Claude, hand it our prompt, and upload the result to the Database Visualizer. Start with [turn an app idea into a database, with AI](/docs/design-a-database-with-ai).

The second route matters more than it sounds. Bubble only enables the full application export on its Starter plan and above, so four of the six tools need a paid Bubble account. The Database Visualizer does not, which makes the AI route the way in if you are on a free plan.

## Before you share anything

A raw Bubble export contains your API keys. If you are going to send it to anyone, or paste it into an AI tool, run it through the [JSON Sanitizer](/docs/json-sanitizer) first. It takes about ten seconds.
