NeuroLint CLI

Hey Product Hunt! 👋

I built NeuroLint because I was drowning in code quality hell. I was working on my side project Taxfy when my terminal exploded with ESLint errors, hydration bugs, and missing React keys. Hundreds of them. I was ready to give up. Out of desperation, I asked Cursor to help. It generated some basic fix scripts and they actually worked. Errors dropped significantly. I thought "okay, these are useful" and moved on. But I kept coming back to those scripts. Every time I hit a new class of bugs, I'd extend them. Eventually I realized: this could be a real tool. I spent months making them robust, added proper AST parsing, built in automatic backups, created a 7th layer that learns patterns from your codebase.

That became NeuroLint.

What it does: → Fixes 50+ code issues automatically across 7 intelligent layers → Handles React 19 and Next.js 16 migrations (the breaking changes that take hours to fix manually) → Guards against hydration errors, adds missing accessibility attributes, cleans up patterns → 100% deterministic—no AI unpredictability, just rule-based transformations.

Why it's different: → Actually fixes your code (doesn't just tell you what's wrong) → Built-in backup system (every change is reversible) → Completely free and open source (no premium tiers, no paywalls) → Works on React, Next.js, TypeScript, JavaScript

Try it:

npm install -g @neurolint/cli
neurolint analyze . --verbose
neurolint fix . --all-layers --dry-run

I'd love your feedback:

• What's your biggest code quality pain point?

• Would this fit into your workflow?

• What frameworks should I support next?

Thanks for checking it out! 🚀
