ShipFuel
Plug-and-play paywall and monetization for vibe-coded apps.
The Idea
Every week, thousands of indie hackers and "vibe coders" ship small apps with Cursor, Replit, and v0 — and then have zero idea how to monetize them. ShipFuel is a single npm package (or a copy-paste snippet) that drops a paywall, usage gate, or subscription flow into any app in under an hour. One command, your Stripe keys, done. The app is now a business.
Why Now
The vibe coding explosion is real. Replit hit 35M users. Cursor went from zero to $100M ARR in under two years. A new wave of non-technical founders is shipping real products — but monetization remains a complex, engineer-heavy problem. Stripe is powerful but intimidating. Lemon Squeezy is better but still requires setup. Nobody has built the "one-liner monetization" for this audience. The window is open right now.
How to Build
Start with a React/Next.js library that wraps Stripe Checkout and Usage APIs behind a simple API: `<Paywall plan="pro" />`. Add a CLI: `npx shipfuel init` that wires up your Stripe keys and generates the required API routes. Include pre-built UI components (modal, inline, upgrade banner). Ship a usage-based tier too — perfect for AI apps. Then build a ShipFuel dashboard showing revenue, conversions, and plan breakdowns across all your apps.
Revenue Model
0.5% of revenue processed (capped at $50/month per project). Free under $1K/month processed — this removes all friction for early adopters. Pro plan: $29/month flat for teams that want unlimited apps + analytics. Usage dashboards as a standalone upgrade. The take rate model scales beautifully with the indie hacker audience: they start free, you scale with them.
Effort
2 weeks to a solid v1. Week one: core library + Stripe wiring + basic UI components. Week two: CLI tooling + dashboard + docs. Distribution is the actual work — ProductHunt, IndieHackers, Cursor's Discord, r/webdev. Budget 4 weeks for a launchable product.
Risk
Stripe already has Stripe Billing which technically solves this. Paddle and Lemon Squeezy have head starts in the indie market. The risk isn't the tech — it's distribution and whether the target audience is willing to pay vs. DIY. The take-rate model mitigates this: you earn nothing until they do.
Verdict
Strong 8/10. Genuinely underserved market, novel positioning, perfect timing with the vibe coding wave. The take-rate model aligns incentives perfectly. Build this, get it into Cursor's community, and let word of mouth do the work.
