Price tracking system for Turkish marketplaces?

Hey everyone,

I want to build a price comparison website focused on Turkish e-commerce platforms.

Instead of building everything from scratch, I’m looking for an existing open-source project or a solid scraper/crawler infrastructure that I can adapt for Turkish marketplaces like Trendyol, Hepsiburada, Amazon TR, N11, etc.

I’d especially appreciate recommendations for:

• Open-source price comparison platforms
• Product scraper/crawler frameworks
• Marketplace parsing systems
• Affiliate / price tracking infrastructure
• Elasticsearch / Meilisearch based setups
• Python or Node.js projects

If anyone has built something similar before, I’d love to hear your recommendations, architecture ideas, or GitHub repos that could be a good starting point
