or
Drop your project folder here or a .zip archive (Lovable, Bolt, v0, Replit export…)

No code is executed; files are deleted after the analysis, and dependencies (node_modules…) are never uploaded. Private repository: the GitHub connection opens by itself, or drop the project folder.

What we check

Seven areas, the same for every project, designed around the typical problems of AI-written code.

Security

Are your data and keys protected?

Production readiness

Can you ship and maintain it with confidence?

Structure

Is the code split up in a way that’s easy to follow?

Duplication

Is the same code written more than once?

Dead code & debt

Is the project weighed down by abandoned code?

Stack

Are the tools consistent and up to date?

Docs & AI context

Can a human or an AI agent understand the project?

Project map

What your code does: pages, APIs, tables, external services, structure. So you can take back control.

A label you have to earn

The label follows the Vybel Standard, a public methodology. To get an A, a project must be tested, have no important issues, and be solid in all 7 areas. Every label carries an ID and the analyzed commit, so a recruiter, a client, or a buyer can verify it.

Frequently asked questions

What is Vybel?

Vybel analyzes the code of your project, written by hand or with AI (Lovable, Bolt, v0, Cursor, Claude Code…), and gives it a grade from A to E across seven areas. Every issue found is explained, with the files involved and a fix prompt to paste into your AI agent.

How is the grade calculated?

With fixed, public rules and no AI: the same code always gets the same grade. The full methodology, the Vybel Standard, details every rule and its weight.

Is my code safe?

No code is executed. Files are analyzed, then deleted when the analysis ends, and dependencies (node_modules…) are never sent. For a private repository, Vybel reads only the repositories you choose on GitHub, read-only, and the report is visible to your account only.

How much does it cost?

The first analysis of every project is 100% free, full report and prompts included. Analyzing a project again costs €5.99 excl. VAT, without creating an account, with the invoice sent by email. Vybel Pro costs €4.99 excl. VAT per month per labeled project, with access opening in waves from the waitlist: daily routine, Monday recap, live badge and two on-demand analyses a month, then €1.99 excl. VAT per analysis.

Which languages are analyzed?

Deep analysis covers JavaScript, TypeScript, Python, Rust, Go, Java, Kotlin, Swift, C#, C, C++, PHP and Scala; the import graph (dead code, circular or broken imports) covers JavaScript, TypeScript, Python and Rust. Other languages get the general rules: size, duplication, secrets, documentation.

How do I analyze a private repository?

Connect GitHub and choose the repositories Vybel may read, read-only; you can withdraw this access whenever you like. You can also drop the project folder or a .zip archive on the home page.

What is a verified label?

Every report carries a number and the analyzed commit: a recruiter, a customer, an investor or a buyer can check the grade on Vybel. With Vybel Pro, the verified owner of a repository displays a live badge, always up to date, on their website or README.

How do I improve my grade?

Start with the priorities of the report: every issue comes with a prompt ready to paste into your AI agent (Claude Code, Cursor, Codex…). Fix, then run the analysis again (€5.99 excl. VAT, or included in Vybel Pro).

Who is behind Vybel?

A team of experts: developers, DevOps engineers and artificial intelligence specialists, with years of experience. Vybel is published by OVO SAS, a French company.
