I built a short-code marketplace with zero npm dependencies (Node.js 22, no framework)

I've been going back and forth on whether to share this — it's a pretty niche idea, and I wasn't sure if it's clever or just weird. But here's the technical side of it, which I figure this crowd might actually appreciate regardless. What I built: claimo.me — you claim a short code (2-4 letters, or a custom name) for a one-time fee, no subscription, permanently yours. Each code is configurable as a redirect link, a QR code, or a small profile card. There's also a "Claimo Map" — every possible code is a clickable pixel you can browse, inspired by the old Million Dollar Homepage. The part I actually want to talk about here: it's zero-dependency. No Express, no ORM, no build step — just Node.js 22+'s built-in http module and the new built-in node:sqlite. I wanted to see how far "just the standard library" actually gets you for something real — payments (Stripe), admin moderation, rate limiting, a live interactive map UI, the works. Some things that surprised me building it this way: node:sqlite's DatabaseSync is genuinely pleasant to use, but it's missing conveniences like better-sqlite3's .transaction() helper — I ended up writing a small manual BEGIN/COMMIT/ROLLBACK wrapper. Routing without a framework is maybe 40 lines of code and I stopped missing Express within a day. The real cost isn't runtime performance, it's losing the ecosystem — anything I'd normally npm install for free (input validation, rate limiting, even basic templating) I had to hand-roll. Some of that was genuinely good for me, some of it I'd reconsider on a bigger project. Business side, since half of you will ask: it's a real registered business, payments go through Stripe only (I never touch card data), no crypto, nothing weird. The paid tiers fund keeping a free short-link tier alive too. Honestly — is the zero-dependency thing a genuinely good call for a real production app, or am I just going to regret it in a year? And separately: does "own a short code" as a product idea make any sense to you, or does it feel like a solution looking for a problem? Happy to go deep on any part of the stack. claimo.me — and if you want to actually poke at it, PROMO50 at checkout gives free Countryside-tier codes (normally €2), just for honest feedback.
