SaaS Detective

Instantly identify the tech stack and SaaS tools used by any website.

* SaaS Detective* SaaS Detective — Tech Stack Intelligence & Checkout Trust Score for Any Website Every website leaves a trail. SaaS Detective reads it — and tells you whether you can trust what you find. One click. Any website. Under 2 seconds. SaaS-Detective scans the active page and does two things at once: it surfaces every tool, platform, and framework powering the site, and it scores whether the page is safe to trust with your payment details. Walk into any sales call, competitive audit, or unfamiliar checkout already knowing what you're dealing with. No source code. No guesswork. Just answers. ━━ WHY IT MATTERS ━━ The modern web runs on dozens of invisible tools — CRMs, analytics platforms, ad pixels, payment processors, A/B testing software, live chat widgets. These tools reveal how a business operates, what they spend money on, and where the gaps are. SaaS Detective makes all of it visible, instantly. 800+ technology signatures. 64 categories. Results in under 2 seconds. ━━ WHO IT'S FOR ━━ Sales Professionals- Stop walking into discovery calls blind. Know what CRM they're on, what analytics they run, how they handle payments, and what ad platforms they're buying — before you dial. Walk in with context. Close with confidence. Founders & Strategists See the exact toolset behind companies you admire or compete with. Find out what's working in your space without spending months testing it yourself. Validated signal, not gut instinct. Agencies & Consultants Audit any prospect's stack before the first meeting. Spot outdated tools, redundant software, and integration gaps. Show up as the expert who already did the homework. Developers & Engineers Instantly identify frameworks, libraries, CDNs, and infrastructure without touching a line of source code. Reverse-engineer architecture decisions in seconds. Online Shoppers Before you enter your card number on an unfamiliar site, get a plain-English read on whether it looks safe — see Checkout Trust Score below. ━━ WHAT IT DETECTS ━━ SaaS Detective covers 64 technology categories including: · Analytics & tracking · CRM & sales platforms · Heatmaps & session recording · Live chat & customer support · Email & marketing automation · E-commerce platforms & payment processors · JavaScript frameworks & libraries · Ad pixels & retargeting networks · A/B testing & feature flags · Scheduling, forms, video, and more 800+ signatures in total — and growing with every release. SaaS Detective contains affiliate links. When the extension detects a tool on a website, it may show a link to that tool, and we may earn a commission if you sign up through it — at no extra cost to you. ━━ CHECKOUT TRUST SCORE (Pro) ━━ Before you buy from a site you don't recognize, SaaS Detective can score it for you. Checkout Trust Score checks the page you're on for the signals that actually matter — a valid SSL certificate, a recognized payment processor, and how long the domain has been registered — and turns them into a plain verdict, from "Excellent — safe to checkout" to "Do not enter payment information," with the specific reasons behind the score. No more guessing whether an unfamiliar storefront is legitimate before you hand over your card. ━━ FREE VS PRO ━━ Free — Detects the 50 most common tools on any page, no account, no login, no credit card. A locked preview shows when Checkout Trust Score has something to tell you, so you always know it's there. Install and start immediately. Pro — Unlocks the full library of 800+ signatures across 64 categories, plus the full Checkout Trust Score breakdown on every page you visit.

Try Pro free for 7 days by email, no credit card required. ━━ PRIVACY ━━ Tech-stack detection runs entirely in your browser on the active tab — SaaS Detective reads script tags and page resources locally, and that page content never leaves your device. We do send limited product-usage analytics (a per-device identifier, scan counts, and which features you use) to help us improve the extension. Before you activate a trial or paid license, that data is pseudonymous and not tied to your name or email. If you do activate a trial or license, your email is then linked to that usage data so we can support your account — this is described in full in our privacy policy, along with the third-party processors involved (PostHog for analytics, Stripe for payment, Cloudflare for our backend).
