See the exact toolset behind businesses you admire or compete with. Validate stack decisions with real-world signal instead of guesswork.
Audit any prospect's stack before the first meeting. Spot outdated tools and integration gaps. Show up as the expert who already did the homework.
Identify frameworks, libraries, CDNs, and infrastructure on any site in seconds — no digging through source code, no guessing.
Visit a competitor, a prospect, a brand you're studying — SaaS Detective works on the entire web, on any page, instantly.

At 33 I was a Nissan mechanic. COVID hit, forced retirement, and I had nothing.
I spent the next 5 years teaching myself to code from scratch. No bootcamp. No CS degree. Just docs, YouTube, and a lot of late nights.
SaaS Detective started as frustration — I kept landing on competitor sites and had no idea what tools they were running. Twenty minutes in DevTools later, I'd have a partial answer. There had to be a better way.
Turns out a lot of people have the same problem.
