I want to replicate the smooth, point-and-click experience of warmmind.space—but tailored to major e-commerce sites. The application’s core is intelligent, reliable form filling that behaves like a real shopper from sign-up all the way through the final “Place Order” button. Key flows I need covered: • Account creation & profile management, including handling multiple identities and stored credentials • Price tracking with real-time comparison across the same product on competing stores, triggering alerts or auto-actions when thresholds are met • Fully automated checkout that completes shipping, billing, and payment screens without tripping fraud or bot filters I’m open to your preferred tech stack—Selenium, Playwright, Puppeteer, or a custom headless approach—as long as it stays lightweight, cross-platform, and avoids detectable footprints. Clear documentation and an intuitive UI or command interface are required so I can add new sites or tweak steps without touching the core code. Deliverables will be accepted when: 1. The software reliably runs end-to-end on at least three mainstream e-commerce sites of my choice. 2. Checkout success rate and price‐tracking accuracy are demonstrated in a recorded session. 3. Source code, build instructions, and a quick-start guide are provided. If you’ve built similar automation tools before, let’s talk about how we can bring this to life quickly and securely.
