Just shipped my first fully live open source project: Schema Lens, a VS Code extension. The Problem I'm not even a SQL person. Never shipped a production SQL project. My world is NoSQL + MongoDB. But I've watched SQL devs suffer trying to visualize schemas from migration files. Live ER diagrams? Painful. Even for MongoDB, I need schema clarity. So I built what I needed. The Solution Schema Lens: lightweight, free, open source VS Code extension. Install → open migration file → ≋ ERD button appears → live diagram renders side-by-side your code. No database connection. No cloud. Just your files. The honest part This is a vibe-coded project. Built fast, shipped fast, learning in public. Rough edges exist. But guardrails are real: tests, CI, AGPL v3 licensed, fully open source on GitHub. I'm an engineer who believes the best tools solve small painful problems simply. This is one of those tools. If you live in migration files (SQL, Prisma, Drizzle, Knex), give it a try. Break it. Tell me where it hurts. Built in Kerala. Shipped to the world.
