BuiltWith is a website technology lookup and lead list tool. Enter a domain and it shows the software that site runs. Pay for a plan and it builds lists of every site using a given technology.
Quick verdict: BuiltWith is one of the deepest technographic databases available, and a strong choice for market research and long-tail technology tracking. It's expensive for simple prospecting. The $295 Basic plan covers only two technologies, so most regular users will need Pro at $495 a month.
Disclosure: we make TechPeeker, a cheaper competitor, so we have a bias. BuiltWith's prices were checked on its plans page in October 2026.

What is BuiltWith?
BuiltWith is an Australian web technology profiler that launched in August 2007. It crawls websites and identifies the tools they use, from ecommerce platforms and analytics to ad pixels, SSL providers and CDNs.
Sales teams use it to find companies running a specific product. Competitive analysts use it to track who is adopting or dropping a technology. Investors and researchers use its history to study market share over time.
It has two limits worth knowing. It can only see technologies that leave a trace on the public website, so back-office software often goes undetected. Its answers also come from crawled data, so a recent change may not show up straight away.
BuiltWith pricing in 2026
BuiltWith has three paid plans from $295 to $995 a month, and Pro is the realistic starting point for regular use. Yearly billing costs 10 times the monthly price, which is about 17% off.
| Plan | Monthly | Yearly | Technologies | Keywords | Retail reports | Logins |
|---|---|---|---|---|---|---|
| Basic | $295 | $2,950 | 2 | 2 | 2 | 1 |
| Pro | $495 | $4,950 | Unlimited | Unlimited | Unlimited | 1 |
| Team | $995 | $9,950 | Unlimited | Unlimited | Unlimited | Unlimited |
Three things matter more than the headline price:
- Basic runs out fast. A list of Shopify stores using Klaviyo and Yotpo needs three technologies, which puts you on Pro.
- Team mostly buys logins. If one person uses the account, Pro gives you the same list limits for half the price.
- The minimum term is real. It's one month on monthly plans and one year on yearly plans, so even a one-off report costs at least $295.
BuiltWith says plans can be canceled at any time and plan changes are refunded pro rata. Single-site lookups stay free.
Key features
BuiltWith's main strength is breadth: technology lists, history and enrichment all sit in one product.
| Feature | What it does | Worth knowing |
|---|---|---|
| Technology lookup | Shows a site's detected tools | Free for single sites |
| Technology lists | Finds all sites using a given technology | Basic allows 2 technologies |
| Keyword lists | Finds sites with specific words on their homepage | Basic allows 2 keywords |
| Trends and history | Shows adoption over 18+ years, with first and last detected dates | Its clearest advantage over newer tools |
| Change alerts | Notifies you when sites start or stop using a technology | Useful for timing outreach |
| Spend and revenue estimates | Estimates what sites spend on technology | These are estimates, not billing data |
| Contact data | Adds names and emails to some records | EU and California contacts are excluded |
| CRM integrations | Syncs with Salesforce, HubSpot, Dynamics 365, Pardot, Zoho and Close | Native, so no API work is needed |
| API | Credit-based access to lookups, trends and domain relationships | Credits limit how much you can pull |
| Exports | Downloads reports as CSV or Excel | G2 reviewers report messy large exports |
| Browser extension | Shows a site's tools in one click | Free on Chrome |
What users say about accuracy
Users rate BuiltWith well overall, but several say its data needs checking. On G2 it holds 4.3 out of 5 from 63 reviews, with 56 of those at four or five stars.
The same reviewers call the data generally strong but not always right, and one had to confirm certain tools manually. On Capterra, where it scores 4.2 out of 5, one reviewer called its accuracy middling and preferred another tool. Another said its client lists were accurate in some cases but not all.
You'll see accuracy percentages quoted for BuiltWith on other sites. Most come with no published method, often on pages selling a competing product, so we've left them out.
BuiltWith pros and cons
The trade-off is simple: you get unmatched depth, and you pay heavily for it.
| Pros | Cons |
|---|---|
| Very large coverage across technologies and domains | Expensive, the most consistent complaint in reviews |
| 18+ years of technology history | Basic is limited to 2 technologies and 2 keywords |
| Long-tail detection, including ad pixels and CDNs | Large CSV exports can need substantial cleanup |
| Spend and revenue estimates | Data is not always correct, per user reviews |
| Native CRM integrations | Contact coverage excludes EU and California |
| Free lookups and browser extension | The interface can feel cluttered to new users |
| Unlimited logins on Team | Pro includes only 1 login |
Who should use BuiltWith?
BuiltWith suits teams that use its history and depth, and it's overkill if you only need lead lists.
| Pick BuiltWith if you | Skip it if you |
|---|---|
| Research market share or adoption over time | Only need current lists of sites using common platforms |
| Track long-tail scripts and niche technologies | Need verified emails and direct dials as your main output |
| Want spend estimates to qualify accounts | Have a budget well under $295 a month |
| Need native CRM sync for a sales team | Check a site only occasionally, since free lookups cover that |
Is BuiltWith worth it in 2026?
Yes, if you'll use its history, long-tail data or CRM integrations. Those are hard to replace, and no cheaper tool we know of matches its depth.
No, if your goal is a list of sites running common technologies. In that case you'd pay at least $495 a month for depth you won't use.
That second group is who we built TechPeeker for. Starter is $99 a month with unlimited technology lists and leads per export. It covers 800+ technologies across 17 million websites, far fewer than BuiltWith. It also has no historical data, spend estimates, contact names or native CRM sync.
