Your resume vs. 6 real enterprise ATS engines

Most free ATS checkers hand you one invented score and paywall the rest. ATS Screener returns six honest scores from six real enterprise platforms, each modeling that vendor's own parser strictness, keyword strategy, and calibrated thresholds. Your resume is parsed entirely in your browser and never uploaded; only the extracted text is sent for AI scoring. A live counter has tracked 2,000+ people through it.

40+ network tools in one app

Netdash folds 40+ network engineering utilities into one web and desktop app: subnet and VLSM planning, IPv4/IPv6 calculators, multi-vendor config generation, IP-conflict detection, and DNS-over-HTTPS. Every calculation runs client-side with RFC-correct algorithms; the Electron build adds a Node.js backend for raw ICMP ping, traceroute, and port scanning that browsers can't do. Signed-in users get Firestore project sync with role-based sharing.
