ESLint for v0 prompts

Showcase
1

Hey everyone,

I just launched an open-source project called v0 Prompt Linter, an ESLint-style linter for v0 prompts.

What it does:

  • Analyzes prompts before sending them to v0

  • Flags errors, warnings, and suggestions

  • Scores prompt quality (0–100)

  • Generates an improved prompt without changing intent

The goal is simple: Help users write clearer prompts and achieve a better UI in v0.

It’s built using v0 itself, fully open source, and easy to extend with new rules.

Live demo: https://v0lint.vercel.app
v0 Chat/ Template: https://v0.link/v0lint
GitHub: https://github.com/techchintan/v0-lint

I’d love feedback, ideas for new lint rules, or suggestions from the community

Motivation behind this ship:

I have often found myself wishing for a tool like this. Every time I build something based on the initial prompt, I realize I’ve missed something or need to refer to documentation.

Sometimes, I have to refine my prompt using other tools or AI models.

To address this issue and save time in my daily work, I created this using the official v0 resources.

I intentionally posted it as open-source so I can leverage other folks’ suggestions to improve accuracy.
