Build your own apps
for the price of a coffee
Stop paying monthly for tools you barely use. Specsy specs are step-by-step blueprints, reviewed by a human for safety and tested to work. Paste one into Claude Code and walk away with an app that lives on your machine. No subscriptions, no coding experience, no pretending this was built for you.
How it works
Three steps from zero to working app.
Pick a spec
Browse the marketplace and find a blueprint for the app you want. Every spec is verified safe. From $3.
Paste and build
Open Claude Code (it's free), paste the spec in, and follow along. Claude does the building. You just say yes.
Own your app
You get a working app on your machine. No subscription, no hosting fees, no vendor lock-in. It's yours.

Why a spec and not a finished app?
A finished app is someone else's product. You pay monthly, you play by their rules, and if they shut down, you lose everything.
A spec builds something that's actually yours. Your data stays on your machine. You can change it whenever you want. And you never pay another subscription fee.
Browse specs →Every spec verified safe. Every spec verified to work.
When you paste a spec into Claude Code, you're giving it instructions to run on your machine. That's a trust problem, and specsy takes it seriously.
Every spec passes an automated safety scan and is read by a human reviewer before it goes live. We don't just check that it's safe — we check that it actually builds cleanly and produces a working app. If it doesn't meet the bar on either count, it doesn't go up.
