Questions & Answers

As answered by people managing Vyze.dev and ExtendsClass JSON Generator.

Which are the primary technologies used for building your product?

Vyze.dev's answer

Next.js 16, TypeScript, React 19, Supabase, Node.js CLI, Tailwind CSS, Clerk, and Stripe Connect.

What makes your product unique?

Vyze.dev's answer

Vyze is the first terminal CLI package manager (npx vyze) and marketplace for verified AI Development Systems. Instead of copy-pasting unverified text snippets from web forms, developers deploy framework-tested .cursorrules, CLAUDE.md files, and agent workflows in one terminal command. It also includes an automated AST security scanner engine that detects prompt injection vulnerabilities before deployment.

Why should a person choose your product over its competitors?

Vyze.dev's answer

Vyze treats AI context as engineering code rather than static prompt text. Unlike static web directories or unverified GitHub gists, Vyze automatically compiles and exports rules into native formats for Cursor, Claude Code, and Windsurf simultaneously. It scans every pack for prompt injection security risks and gives creators a 90% revenue split to ensure long-term maintenance of rules.

How would you describe the primary audience of your product?

Vyze.dev's answer

Software engineers, AI prompt engineers, software architects, and tech leads who build applications using AI coding assistants like Cursor, Claude Code, Windsurf, and GitHub Copilot.

What's the story behind your product?

Vyze.dev's answer

We spent dozens of hours tuning custom .cursorrules and CLAUDE.md files for Next.js 15, FastAPI, and Supabase, only to watch AI models hallucinate outdated code whenever frameworks updated. Realizing there was no standardized package manager or verified marketplace for AI editor rules, we built Vyze to provide deterministic, security-scanned context rules for developer teams.
