Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.0
GPA, above 8 of the 49 other lead and email finders we grade
BuiltWith tracks the technologies that websites use and lets you search that data in reverse: list the sites running a particular platform, tool or keyword, then export the results with business contact names, emails and titles where publicly listed. Single-site lookups are free. Paid plans add list reports, usage alerts, trend history and CRM integrations.
To get you started, here are 9 things to know about BuiltWith, taken from its own pages and our grades.
You have to know what to search for and how to build the list.
- 1
Best for lists of sites using a technology
BuiltWith tells you which websites use a given technology and builds lists from that, and one-off site lookups are free.
- 2
Paid plans start at $295 a month
As its pricing page puts it: $295 per month, billed monthly.
- 3
There is a free plan
Individual site lookups are free to use, per the pricing page.
- 4
It runs on Web
Web.
- 5
Technology lists
Reports of websites using a chosen technology, filtered by spend, location and more. The page says it tracks 128,484 technologies across 491.9 million domains.
- 6
Contacts and exports
Every plan includes names, emails and titles of people publicly listed with businesses, and Excel or CSV export of reports.
- 7
Alerts and predictive leads
Usage alerts when sites start or stop using a technology, and lists of companies that may be about to switch platforms.
- 8
A 2.0 GPA, above 8 of 49
That is against the other lead and email finders we grade, on value, the free plan, features, ease of use and platforms.
- 9
Keep it
To replace BuiltWith you would be making a library of papers and sources to search. That is not a weekend's work, with an AI app builder or without one.

The report card
Best for lists of sites using a technology
BuiltWith tells you which websites use a given technology and builds lists from that, and one-off site lookups are free. But paid plans start at $295 a month with nothing cheaper, and the first plan covers only 2 technologies.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | D | $295 a month on Basic, about six times the $49 middle of lead-finding tools, with the dearest tenth starting at $99. It's a different kind of data, but there's no cheaper step. |
| Free plan and trial | C | Single-site lookups are free. The lists and exports are not, and there's no free plan for them. |
| Features | C | Technology lists, contacts, alerts, trends and spend data. Basic is limited to 2 technologies, 2 keywords and 2 retail reports. |
| Ease of use | C | No store rating on record. You have to know what to search for and how to build the list. |
| Platforms and integrations | B | Web only, with six integrations including CRM and AI agent connections. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

Part 04 · Standing
Where it stands
Its grades against its category, and whether to keep it or make your own
8/49
Other lead and email finders it is graded above
BuiltWith's GPA of 2.0 is higher than 8 of the 49 other lead and email finders we grade, and level with 6.
It stands best on platforms and integrations (B, above 9 of 49) and worst on value for money (D, above 1).
Its paid plans start at $295 a month, against a middle price of $49 for the category: 38 of the 39 others that charge start lower.
On features, ease of use and platforms it scores 2.3 out of 4. 23 tools score higher and cost less.
Each grade against the category
Every bar is all 50 lead and email finders we grade, cut by the letter each got. BuiltWith’s own letter is outlined.
- DValue for moneyAbove 1 of 49
- CFree plan and trialAbove 11 of 49
- CFeaturesAbove 1 of 49
- CEase of useAbove 1 of 49
- BPlatforms and integrationsAbove 9 of 49
Price against what you get
Each dot is one of 40 lead and email finders. Further left costs less; higher up scores better on features, ease of use and platforms. BuiltWith is the marked dot.
What paid plans start at, a month (each step along is roughly double) →
Keep it, or make your own?
Whether this is something you could build for yourself with an AI app builder, and what you would give up.
Keep it
To replace BuiltWith you would be making a library of papers and sources to search. That is not a weekend's work, with an AI app builder or without one.
That makes this kind of software worth paying for, not this one in particular: 35 of the 49 other lead and email finders grade higher. It costs $3,540 a year.
What you could make
- Reports: an app builder makes this well.
What you could not
- A library of papers and sources to search.
- It plugs into other products, Salesforce, HubSpot and Microsoft Dynamics 365 among them, and has an API.
What this rests on. BuiltWith’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
