Tools to monitor DTC competitors and trends?

Curious to learn from others building or running DTC ecommerce brands (Shopify, WooCommerce, etc.).

What workflows or tools do you use to: Monitor what your competitors are doing (product launches, plugins, growth) Track category-level trends or shifts in strategy Discover emerging brands or fast movers Understand what’s working in your space — beyond SEO/ads

I've seen people use tools like Semrush, Storeleads, Similarweb, and even custom scrapers or Notion dashboards. Some say it's too fragmented.

If you're running a store, building tools for ecommerce, or just hacking around this space, I'd love to hear: What’s working for you? What’s missing in existing tools? Are there any “insight stacks” you’ve built for yourself?

Thanks in advance — learning a lot from this community!
