[For Sale] LeadRot.com - Find businesses with ugly websites so you can pitch them. Full source code, $4K. Open for offers.
Hey everyone,
I built a SaaS called LeadRot that helps web designers and agencies find local businesses with outdated, ugly websites so they can pitch redesign services to them.
It's finished, production-ready, and I'm selling it for $4,000. No revenue yet, no users. You're buying the product, the code, and the domain.
How it works:
You pick an industry (dentist, plumber, roofer, whatever) and a city. LeadRot scrapes Google Maps, pulls every matching business, screenshots their website, runs a Lighthouse audit, and then sends the screenshot to Google Gemini for a visual critique. It checks 26 technical signals (things like SSL, mobile viewport, jQuery version, copyright year, autoplay video) and assigns a score from 0 to 100 with badges like "Dated," "Ugly," or "Hideous."
Then it generates personalized cold email hooks that reference actual problems on that specific site. Not generic "your website could use some work" copy, but stuff like "noticed your homepage loads three competing font families and the hero image is stretched past its original resolution." You export to CSV and drop it into whatever cold email tool you use.
The whole process takes about 3 minutes per search.
Why $4,000 for a pre-revenue product?
Because you're buying roughly 15,000 lines of production TypeScript that would cost $15K-25K to contract out. Next.js 15 App Router, Supabase Auth + Postgres, Cloudflare R2 for screenshot storage, Lemon Squeezy for billing (4 subscription tiers + credit packs, all wired up), a full multi-tenant admin panel, legal pages, the works.
Monthly infrastructure runs about $5. Not a typo. The unit economics are solid too: it costs about $0.0025 to analyze one business, so even at the cheapest plan ($29/mo for 500 credits), gross margins sit around 96%.
What's included:
- Full source code (Next.js 15, TypeScript, ~15K LOC)
- Domain: leadrot.com
- Supabase database with production migrations
- All API integrations (Apify, OpenRouter/Gemini, Cloudflare R2, Lemon Squeezy)
- Multi-tenant admin panel with superadmin controls
- Legal pages (Terms, Privacy, Refund, Cookies, GDPR endpoint)
- 74,000-word Product Requirements Document
- Buyer runbook with full setup instructions
- 30 days post-sale support
What's not included:
- Third-party API accounts (you create your own, all have free tiers)
- Revenue guarantees
Why I'm selling:
I built this to validate a concept for my own workflow. It works, it's done, but I've got other projects pulling me in different directions, and I need the capital. Nothing is broken. It just needs someone with the time to market it properly.
The growth playbook is obvious: Product Hunt launch, content marketing ("I scraped 1,000 dentist websites, here's what I found" type posts), YouTube demos, affiliate program through Lemon Squeezy, SEO for keywords like "ugly website finder." The niche is validated. Competitors like Ugly Site Scraper charge $29-$119/mo and have paying users.
