Outsmarting Datadome: How a Vinted Scraper Scaled to 26 EU Markets

As marketplaces restrict their APIs to enterprise customers, defeating modern bot detection becomes essential for developers seeking programmatic data access. This technical deep dive reveals the six-layer architecture—residential proxy rotation, browser fingerprinting, cookie persistence, geo-aware routing, adaptive backoff, and multi-mode parallelization—that transformed a prototype failing in 18 seconds into a production system running 97,900+ times across 26 EU markets for 250+ users. For anyone building data tools against Datadome-protected services, this represents distilled experience that would otherwise take months of trial-and-error to develop.
