About netlens

built by Yossi Ben Hagai · SRE · software engineer · security & network · applied AI

netlens is an analysis and workflow tool for engineers who investigate real systems. It is not another commodity DNS lookup site. Every module contributes to a correlated report: raw data, interpreted findings, likely root causes, reproducible commands, and machine-readable JSON.

Why it exists

Most lookup tools dump information. They leave the hardest part - interpretation - to you. When something is wrong in production, you don't need 9 browser tabs of DNS records, header dumps, and cert timelines. You need "the CDN is in front of this domain but the A record is your origin ASN, so the origin is probably directly reachable" in one sentence.

Design principles

• Correlation over concatenation. Findings combine signals across modules.
• Reproducibility. Every check has a copy-paste command.
• API-first. GET /api/analyze?input=… returns the same report the UI renders.
• MCP-ready. Every module is a registered tool (/api/tools). Wiring an MCP server is a thin adapter layer.
• Honest about limitations. See docs/limitations.md in the repository.
