Could you build this?
Partial The comparison frontend and calculator are straightforward, but building and continually maintaining 648 distinct bank web scrapers across 51 countries is an immense data engineering effort.
What it would actually take: The system requires a distributed web crawling framework (Playwright, Puppeteer, Scrapy) orchestrating 600+ scrapers that parse dynamic bank tables, PDFs, and rate boards, paired with anti-bot evasion and rate normalization pipelines. Maintaining this scale demands dedicated scraping infrastructure, proxy rotation, and ongoing maintenance as bank portals frequently update their DOMs.
