What it does

Wappalyzer and BuiltWith charge $500+/mo for technographic data. The SaaS Spend Scanner does the same job per-result. One URL in, full SaaS stack out, with monthly spend estimates based on typical SMB and mid-market pricing.

Detects 60+ apps from script tags, CSS classes, DOM signatures, and TXT records: Salesforce, HubSpot, Intercom, Zendesk, Atlassian, Slack, Notion, Linear, Asana, Monday, Klaviyo, Mailchimp, SendGrid, Stripe, Recharge, Yotpo, Hotjar, Mixpanel, Amplitude, Segment, FullStory, Drift, Calendly, Typeform, ConvertKit, Loom, and more.

Use the $0.01 detector tier when you just need the stack list. Use the $0.03 AI tier when you want spend estimates, consolidation opportunities, and a narrative summary written for you.
