A robust SEO parser: powerful presets, but Docker/WSL installation is a bit tricky.
I use A-Parser as a workflow tool for regular data collection tasks, and overall it's proven itself: it's fast, flexible, and well-suited for scaling data collection across multiple streams and rotating proxies. With careful configuration of delays/streams and proxy profiles, I was able to reliably collect the required URLs from listing pages, and the presets really save time on repetitive scenarios.
The biggest drawback for me is the initial learning curve and installation nuances, especially when paired with Windows + WSL + Docker: it's easy to hit a "wrong path," a volume mount conflict, or simply a situation where the container doesn't see the binary and crashes. However, when you follow their Docker instructions (mount the aparser folder and run the web interface on 9091), everything works predictably.
I'll point out separately: the product feels like it's designed for those who understand what they're doing (proxies, restrictions, captchas, anti-bot), not for those who just push a button and get magic. If you're willing to properly assemble an environment and presets for your needs once, the tool is very powerful.
