Cartify source
The full code behind a live recipe-to-cart app. Point it at a new niche by swapping two files.
Cartify reads a web page, pulls out a list of items, and turns each one into a store search link with your affiliate tag on it. That pattern works for far more than recipes. This kit is the whole thing: tested, documented and free to host.

Questions about this kit
Which stores does it link to?
India: Swiggy Instamart, Blinkit, Amazon Fresh and Amazon Now. US: Instacart, Walmart, Amazon and Target. UK: Tesco, Sainsbury’s, Ocado and Amazon. A preset is a list of stores and their search URL patterns, so adding a store or a country is an edit to one file.
Does it cost anything to run?
Not by default. Extraction uses OpenRouter’s free model routing with your own free key, there is no database, and the setup guide deploys to a free hosting tier. Free models have rate limits.
What does the SSRF guard do?
Cartify fetches pages that users paste in. The guard stops anyone from pasting an internal address to make your server fetch something it should not. It has its own tests.
Do I need AdSense or affiliate accounts first?
No. The wiring is there and waits for your IDs. Add them when you have them.
Can I build a paid product from it?
Yes. Run ads, add affiliate links, charge a subscription or build it for a client. What you cannot do is resell or publish the source code itself.
What is in the promo video kit?
Five ready-to-post vertical reels (1080 × 1920, about 18 seconds each) showing Cartify in use: chili oil noodles, Tuscan chicken, dum biryani, protein meal prep and a recipe link. Each comes with a cover image and SRT subtitles, plus the voiceover scripts so you can re-record them for your own brand.
Refunds?
Sales are final, because a kit is a download. Try the live demo first: it runs the same code.
