B2B Supplier Portal Automator by KhyFee.
Playwright logs into supplier portals with cookie session reuse, diffs prices, and alerts when increases exceed 5%. Deterministic automation — no AI.
Developed privately before this public release — commit history reflects open packaging, not a simulated multi-month timeline.

Node.js · Playwright · Supabase Postgres schema · Docker · Next.js status dashboard · Express dummy portal
Scrapers break when supplier UI changes. v0.1 demos use the included dummy portal only — do not point CI at third-party sites.
