Build an Image Editor Online with Claude Code

Build an Image Editor Online web app. People search for "image editor online" about 59,000 times a month, plus related searches like "edit photos online free", "photo editor web app", "online image editing". The goal is a tool that ranks for those searches and makes money.

What it should do:
Build an online image editor web app. Create a homepage with image upload or camera capture options. Build an editing interface with a central canvas and side panels for tools: crop, resize, rotate, filters, brightness/contrast/saturation sliders. Add a filter gallery with preview thumbnails (vintage, B&W, vibrant, etc.). Include text overlay tools with font selection and color picker. Show before/after comparison and undo/redo functionality. Use a modern design similar to mobile photo apps. Focus on the basic editing tools and filter application first.

How to build it:
1. Read this folder first. If it is empty, set up Next.js (App Router, TypeScript, Tailwind). Write a short PLAN.md with the pages, components, any library or API you need, and what you are leaving for later. Then build.
2. Put the tool itself on the homepage so a visitor can use it within seconds, with no sign-up. Do the processing in the browser where you can, so it is fast and cheap to run. Look at how Photopea, Canva, Pixlr do it and make ours simpler and faster.
3. Make it rank. Use "image editor online" in the title tag, H1 and meta description. Under the tool, add a short how-to and an FAQ with FAQPage schema, and add a sitemap and robots.txt. Scaffold these programmatic pages from one template and a data file: /edit-[image-type]-online, /photo-editor-for-[platform], /online-[editing-feature]-tool.
4. Monetisation: Freemium: Basic filters, $8/mo premium filters + no watermark. Add a pricing page and the free usage limit, and leave Stripe checkout as a clearly marked stub with the environment variables it needs.
5. Run it locally and test the main flow end to end, including edge cases like empty input and very large files. Fix what breaks, then finish with a summary of what works, what is stubbed and how to deploy it to Vercel.

Paste it into Claude Code in an empty folder. It plans first, so read PLAN.md and steer before it starts building.
