Introducing Attune.js

Introducing Attune.js: Your New Code Quality Companion 🔍

I'm excited to announce the release of Attune, a local-first CLI tool for comprehensive code quality checks.

No cloud accounts, no API keys, no data leaves your machine.

Why?

Because vibe code needs a lot of help to be "production-ready". Other tools can help, but many require cloud accounts, send your code to external servers, or have usage limits. Attune runs entirely locally, so your code never leaves your machine. It's fast, private, and works offline.

What is Attune?

Attune analyzes your codebase for security vulnerabilities, architectural issues, performance problems, and best practices—right from your terminal. It's designed to be fast, private, and framework-aware.

Features

• 448 Built-in Rules covering security, performance, architecture, accessibility, and more
• Multi-Framework Support: React, Next.js, Vue, Svelte, Angular, Nuxt, Astro, Remix, Express, Fastify, tRPC
• Security Scanning: OWASP Top 10, hardcoded secrets, SQL injection, command injection
• Multiple Output Formats: Terminal, JSON, Markdown, HTML, and SARIF
• Framework Auto-Detection: Automatically identifies your stack (currently Node/TS-focused, planning Python support by 1.0.0)
• Customizable: .attuneignore and .attunerc support personalized configuration, cli args can change a multitude of settings per-run

Took me a few weekends from concept to get this to a 'beta' state I'm happy with. I'd love your feedback! Try it on your projects and let me know what you think.
