Hey Product Hunt! I built Web Harvester to make web data collection more resilient, measurable, and easier to operate.
It’s an open-source Go project featuring health-aware proxy rotation, adaptive rate limiting, authenticated proxies, runtime configuration reloads, Prometheus metrics, and Redis Streams integration.
I’ve also put it through large-scale load testing and evaluated proxy and search behaviour, documenting both the results and their limitations.
I’m sharing it to get real feedback from developers building scrapers, data pipelines, and collection infrastructure.
Give it a try, inspect the code, and tell me what you’d improve. What would you want to see next?
