BuiltWith vs Clearbit, short answer: BuiltWith is a technographic database: it tells you which technologies a website runs and sells lead lists built on that, from $295 per month. Clearbit is no longer a standalone product. HubSpot acquired it in December 2023 and sells it as HubSpot Breeze Intelligence, which enriches HubSpot contact and company records with firmographic data inside a paid HubSpot subscription. Use BuiltWith to find accounts by tech stack; use Breeze Intelligence to fill in records you already have.
The two are often compared because both touch the same question, "what do we know about this company?", but they answer it from opposite ends. BuiltWith starts from the website and works outward: crawl the site, detect the technologies, build a list. Clearbit started from an email or domain and worked inward: given a record, append company size, industry, revenue, and role. The rest of this guide covers what each actually provides in 2026, what each costs, where each falls short, and how to decide.

What BuiltWith Does Well
BuiltWith is the reference tool for technographic prospecting. Its pitch is building "high intent lists using tech signals, spend, and lifecycle events" and pushing them into your CRM. In practice that covers three jobs:
- Competitive displacement lists. Find every site running a competitor's product and target them with a switch campaign.
- Integration and partner targeting. If your product integrates with Shopify, Klaviyo, or HubSpot, list the companies that run those tools.
- Market sizing. Count adoption of a technology across a region or vertical before you build a territory plan.
BuiltWith's pricing is published and simple. Basic ($295 per month) limits you to two technologies, two keywords, and two retail reports, which suits one narrow use case. Pro ($495 per month) unlocks unlimited technologies, keywords, and reports for one login. Team ($995 per month) adds unlimited Pro logins. Annual billing is priced at roughly ten months of the monthly rate on every tier.
Where BuiltWith stops
- It sees the website, not the company's whole stack. Detection relies on what a site exposes publicly. Back-office systems that leave no trace on the website (a CRM used only by the sales team, an internal data warehouse) are far harder to detect than a tag or script.
- It is not a contact database. You get companies, not the people to email. Teams pair it with a contact source.
- It does not tell you who is in-market right now. Running a technology is a fit signal, not a timing signal.
- It does not act. Lists go to CSV or the CRM, then to separate tools for ads, sequences, and website experiences.
What Clearbit (Breeze Intelligence) Does Well
For a HubSpot customer, Breeze Intelligence is the easiest enrichment layer to justify: it is native, it requires no integration project, and per HubSpot's own knowledge base, data enrichment does not consume HubSpot Credits on eligible Starter, Professional, and Enterprise subscriptions. HubSpot enriches contacts from first name, last name, and work email, and companies from domain.
The default enrichment set covers 14 contact properties (job title, seniority, role, sub-role, LinkedIn URL, location) and roughly two dozen company properties, including annual revenue, employee range, industry, total money raised, year founded, and, notably for this comparison, a Web Technologies property. So Breeze Intelligence does carry some technographic data, but as a field on records you already hold, not as a search index you prospect from.
Where Clearbit stops in 2026
- HubSpot only. If your system of record is Salesforce, Breeze Intelligence is not a standalone option. Our Clearbit Breeze Intelligence alternatives guide covers what Salesforce teams use instead.
- Enrichment, not discovery. It fills in records. It does not give you a searchable index of every company running a given technology the way BuiltWith does.
- Business email required. HubSpot does not enrich personal addresses such as Gmail or Yahoo.
- Visitor identification is company-level. Buyer intent flags accounts, not the individual people on your site.

BuiltWith vs Clearbit: Which Should You Use?
| Your situation | Better fit | Why |
|---|---|---|
| You sell an integration or replacement for a specific technology | BuiltWith | You need a list of every company running that technology |
| You run HubSpot and your records are incomplete | Breeze Intelligence | Native enrichment with no extra integration |
| You run Salesforce | BuiltWith for lists, plus a non-HubSpot enrichment source | Breeze Intelligence lives inside HubSpot |
| You need contacts, not just companies | Neither alone | BuiltWith is company-centric; Breeze enriches contacts you already have |
| You want to know which target accounts are on your site, and who | Neither alone | That needs account-level and contact-level deanonymization |
| You want tech stack, intent, and activation in one place | A platform such as Abmatic AI | One identity graph from detection to campaign |
Many teams end up running both: BuiltWith to source accounts by technology, HubSpot with Breeze Intelligence to enrich them once they land in the CRM. That works, but it leaves the most valuable step unbuilt: deciding which of those accounts is active now and doing something about it across the website, ads, and outbound.

If you are weighing a BuiltWith plus Breeze plus four-more-tools stack, see how Abmatic AI runs it as one platform.
Skip the manual work
Abmatic AI runs targets, sequences, ads, meetings, and attribution autonomously. One platform replaces 9 tools.

Technographic and firmographic data answer "is this account a fit?" They do not answer "is this account in-market this week, who is researching, and what should they see?" That is where most stacks bolt on three or four more products: a visitor identification tool, an intent provider, a personalization tool, a sequencer, and an ad platform. Each has its own copy of the account, its own match logic, and its own bill.
The implementation path we recommend, whatever tools you choose:
- Define the fit signal. Which technologies, sizes, and industries make a good account? This is where BuiltWith-style data or a tech stack scraper earns its keep.
- Add timing. Layer first-party intent (your site, ads, email) over third-party intent so you work the accounts showing activity now.
- Resolve to people. Account-level deanonymization tells you the company; contact-level deanonymization tells you who.
- Act in every channel from the same record. Personalize the site, retarget in ads, and enroll the right contacts in a sequence without exporting a CSV between tools. Walk through this path with the Abmatic AI team.
Where Abmatic AI Fits
Abmatic AI is the most comprehensive AI-native revenue platform on the market. It collapses the 8 to 12 point tools that B2B teams typically buy separately, including a BuiltWith-style technographic tool and an enrichment layer, into one platform with a shared identity graph and shared signal layer. It runs 15+ first-party modules:
- Technology and tech stack scraper: detects a prospect's tech stack on-domain and uses it for targeting and sequence personalization, the job teams buy BuiltWith or Wappalyzer for.
- Account list and contact list building from a first-party database with firmographic, technographic, and intent filters, the job teams buy Clay, Apollo, or ZoomInfo lists for.
- Account-level deanonymization: identifies the companies behind anonymous site traffic.
- Contact-level deanonymization: identifies the individual people behind that traffic, natively.
- First-party intent across web, LinkedIn, paid ads, and email, with third-party intent layered alongside.
- Web personalization and A/B testing: change what an account sees based on its stack, stage, and intent.
- Agentic Workflows: "if an account running a competitor's tool hits an intent threshold, enroll its buyers in a sequence, show a switch banner, and alert the AE."
- Agentic Outbound and Agentic Chat with an AI SDR that qualifies, routes, and books meetings.
- Advertising: native Google DSP, Google Search, LinkedIn Ads, Meta Ads, and retargeting driven by your account list.
- Built-in analytics for pipeline, attribution, and account journeys.
Abmatic AI syncs bi-directionally with both Salesforce and HubSpot, so it works whichever CRM you run, and integrates with Google Ads, LinkedIn Ads, Meta Ads, Slack, Gmail, Outlook, Marketo, Pardot, Snowflake, BigQuery, and Redshift. It is built for mid-market and enterprise teams, scales from 50 to 50,000+ target accounts, goes live in days, and starts at $36,000 per year with enterprise tiers available.

Frequently Asked Questions
What is the difference between BuiltWith and Clearbit?
BuiltWith detects the technologies websites run and sells prospecting lists built on that data. Clearbit, now HubSpot Breeze Intelligence, enriches contact and company records inside HubSpot with firmographic and role data. BuiltWith finds accounts by tech stack; Breeze Intelligence completes the records you already have.
Is Clearbit still available in 2026?
Not as a standalone product. HubSpot acquired Clearbit in December 2023 and now sells its data as HubSpot Breeze Intelligence, available with eligible paid HubSpot subscriptions. Legacy free Clearbit tools were sunset in 2025.
How much does BuiltWith cost?
BuiltWith publishes three plans: Basic at $295 per month ($2,950 per year), Pro at $495 per month ($4,950 per year), and Team at $995 per month ($9,950 per year). Basic is limited to two technologies; Pro and Team are unlimited.
Does Clearbit provide technographic data?
Partly. HubSpot's enrichment includes a Web Technologies company property, so enriched records carry some stack data. It does not offer a searchable index of every company using a technology, which is BuiltWith's core product.
Can I use BuiltWith and Breeze Intelligence together?
Yes. A common pattern is sourcing accounts by technology in BuiltWith, importing them into HubSpot, and letting Breeze Intelligence enrich them. You still need separate tools for visitor identification, intent, personalization, and outbound, which is the gap a platform like Abmatic AI closes.
What is the best alternative to both BuiltWith and Clearbit?
For teams that want tech stack detection, enrichment, deanonymization, intent, and activation in one system, Abmatic AI combines all of them on one identity graph and works with both Salesforce and HubSpot. Request a demo to see it on your accounts.
Bottom Line
BuiltWith and Clearbit are not really substitutes. BuiltWith is a technographic prospecting index with transparent pricing; Clearbit is now Breeze Intelligence, a HubSpot-native enrichment layer. Pick BuiltWith to find accounts by stack, Breeze to complete HubSpot records, and a platform when you want to turn fit data into pipeline without stitching five tools together.
