Clearbit alternative

Clearbit now lives inside HubSpot. TechSpy reads any company's stack from one API.

HubSpot retired the free Clearbit platform, Weekly Visitor Report, Clearbit Connect and the free Slack integration on April 30, 2025, and shut the free Logo API on December 8, 2025. Its enrichment now ships as Breeze Intelligence inside HubSpot. If what you needed was a company's tech stack, TechSpy gives you that per domain, with or without HubSpot.

  • A per-domain tech-stack read with evidence and High / Medium / Low confidence
  • DNS, DMARC, SPF, DKIM and subdomains in the same scan
  • REST API, Zapier, MCP and CLI from Plus at $19/mo, free start at 30 scans a day

Free — no card, 30 scans/day.

TechSpy — the read · acme.io

High

Verdict

Next.js on Vercel with Segment, HubSpot forms and Intercom: a product-led team that instruments its funnel heavily.

Evidence: Next.js runtime + Vercel headers; Segment and HubSpot forms in runtime calls; DMARC p=none.

Implication: push the stack into your CRM record and open with lifecycle tooling, not infrastructure.

TechSpy replaces the tech-stack part of Clearbit, not the people part

Clearbit was used for many jobs: contact and company enrichment, visitor reveal, logos. TechSpy covers one of them deeply: what a company runs and what that means for how you sell. It does not provide contact data, emails or headcount. If you need people data, keep a contact provider and use TechSpy next to it.

What a tech field gives you

techstack: ["Segment", "HubSpot", "Vercel"]

A list to filter on. No evidence, no confidence, no next step.

Not all checkmarks on our side: contact and company enrichment are Clearbit's home turf, bolded below.

What only TechSpy does

The tech-stack depth an enrichment field doesn't carry, turned into an action.

🔍

Deep Scan reads the network tab

A headless browser plus HAR capture surfaces the hidden APIs, SDKs, and third-party calls that never appear in static HTML.

🛡️

Infrastructure, not just front-end tags

Every scan audits DNS, DMARC, SPF, DKIM, and maps subdomains, so you see how a company's email and infrastructure are configured and where the gaps are.

🧭

A read, not a raw list

Tools are grouped by what they mean and turned into a Verdict, Evidence, and Implications with High / Medium / Low confidence. When a site is blocked, it says so.
