ZennoPoster

Pros: Once you get past the learning curve though, it's surprisingly capable. The multi-threading is the real deal — I'm running 20 threads and it barely touches my RAM. The proxy checker saved me a ton of money I was wasting on dead proxies before. Being able to mix visual blocks with C# snippets means I can handle 90% of my tasks without code and drop into code only when I need something custom. The built-in scheduler means I set it up once and literally forget about it — wake up to fresh data every morning. Debug mode where you can step through each action and see exactly what the browser is doing is a lifesaver when a site changes its layout. Also the community forum is active — most of the time someone already solved the problem you're stuck on.

Cons: The 14-day refund window helps, but honestly that's barely enough time to build and test a serious template.

Overall: I've been running ZennoPoster for about 6 months now, mostly for scraping product prices across 12 different marketplaces. Before that I had a virtual assistant doing it manually twice a week — took her around 4 hours each time and the data was already outdated by the time I got it. I built a template in ProjectMaker that logs into each marketplace, grabs prices and stock status for about 3000 SKUs, and dumps everything into a Google Sheet. Runs every night at 2 AM via the built-in scheduler with 20 threads. The proxy checker is solid — I load a list, it filters by speed and country, and the bad ones get dropped automatically. Initial setup took me maybe 3 days since I had zero coding background, but the visual editor makes the logic pretty clear. I caught a pricing gap on one supplier that let me flip products at ~$8 margin each — ended up making around $600 over two months just from that. Not bad for a tool I originally got just to save on VA costs.
