Open-source tools for proxy-powered workflows
A directory of the libraries, frameworks and CLIs we run in production, sponsor, or contribute to — every entry comes with a working proxy snippet.
Most "best open-source scraping tool" lists rank projects the author has never deployed at scale. This one is different. Every tool below is one we've either shipped to a paying customer, integrated with our proxy network, or sponsored on GitHub. No paid placements, no affiliate links.
The list is curated, not exhaustive and most of the projects presented are open source so we encourage you to participate and help us make it better. We add a project when we've used it in anger; we remove one when it stops being relevant.
ProxyMetrics - MITM proxy insights and audit tool
Self-hosted MITM proxy dashboard that creates, per vendor, intuitive dashboards which report spending, bandwidth, IP pool size and accuracy, error rates and much more
Proxy Audit & Truth-in-Advertising
Verify that the proxies you're paying for actually match what was sold. Every request is geo-checked (via API with a MaxMind fallback) and IP-typed so you can see when the exit node's real country, city, or ASN drifts from the location you requested. We flag mismatches automatically - including the big one some vendors hate: residential plans silently serving datacenter IPs. Stop trusting the dashboard and start trusting the data.
Per-Provider Traffic Analysis
Drill into your proxy traffic by provider, profile, and credential to see what you're actually getting for the money. Latency, success rates, geo distribution, IP-type breakdown, and request volume are aggregated from your real traffic - not vendor-supplied stats - so you can compare providers head-to-head, spot degradation early, and decide where to shift budget based on evidence from your own workloads.
