Wyro – Draw a backend on a canvas, export TypeScript with no lock-in

Wyro, a visual backend builder that compiles to a plain TypeScript repo, launched on Hacker News. The tool lets users wire blocks on a canvas and exports a conventional Node project with typed Express handlers, Drizzle schema, and Zod validators, with no runtime interpretation. Founder emphasizes no lock-in: the exported package.json contains only standard dependencies, and users can delete their Wyro account and the app keeps running.

Hi HN. Wyro is a visual backend builder that compiles to a plain TypeScript repo you own outright. The motivation: AI app builders got good at generating apps and stayed bad at letting you leave. Frontend code you can always lift out. The backend is the hostage — their runtime, their DB, their deploy target. How it works: you wire blocks on a canvas HTTP routes, tables, auth, queues, cron, multi-step pipelines into a graph. That graph is an IR, and the compiler lowers it to a conventional Node project — typed Express handlers, Drizzle schema and migrations, Zod validators derived from the table definitions, postgres for the driver. Nothing is interpreted at runtime; the graph isn't shipped, it's compiled away. The test I hold it to: the exported package.json lists express, drizzle-orm, postgres, zod, dotenv, jsonwebtoken. No package of mine. Delete your Wyro account and the app keeps running. Databases work the same way — connect your own Supabase and provisioning happens in your org, on your bill, over the Management API. I hold the canvas, not your infrastructure. Honest state of things: it's early and solo-built. The generated code is the thing I'm most confident about and the thing I most want torn apart. Rough edges are in the surrounding product, not the compiler. Free tier, no card. The useful thing you can do in five minutes is export a project and read the diff-able code before deciding whether you trust it. https://wyro.vercel.app Would especially like feedback from anyone who has migrated off a hosted builder — what broke, and what you wished the export had included.
