Pipl: Rule Tester For VPN

Routing rules look obvious on paper and behave surprisingly in practice. Order matters more than you'd expect, a too-broad keyword quietly swallows the wrong domains, and a regex that seemed airtight matches something it shouldn't. Pipl lets you find out safely — before the rules go live.

Write your rules, paste in sample URLs, and Pipl evaluates them the way a router would: top to bottom, first match wins. For every URL you get a clear verdict — PROXY, DIRECT, or BLOCK — and the exact rule that decided it, highlighted. A surprising result becomes a lesson instead of a mystery.
