Tech stack intelligence BuiltWith Review: Is It Still Worth It in 2026?
BuiltWith is a tech stack intelligence platform for website technology detection and lead generation by technology, best for sales teams targeting a tech-stack ICP. Free single-site lookups are available, and Basic costs $295/month. Skip it if your ICP is firmographic, you only need occasional lookups, or you need contact enrichment and sending bundled.
BuiltWith is the deepest tech-stack intelligence platform: approximately 114,000 technologies tracked across 414M+ domains. Used primarily for tech-based lead generation. Pricing from $295/mo (Basic); free for single-site lookups. Best for sales teams targeting tech-stack ICP ; less compelling as a general enrichment tool.
- Your ICP is defined by specific technology adoption (Shopify, HubSpot, Klaviyo, etc.)
- You run timing-based outbound triggered by tech stack changes
- You need historical adoption data ("recently switched from X to Y")
- Your ICP is firmographic (industry, size, geo): a technographic filter is the wrong entry point
- You only need occasional single-site lookups (the free tool is enough)
- You need bundled contact-enrichment + sender (BuiltWith is data-only)

Overview
What is BuiltWith?
BuiltWith is an Australian tech-stack intelligence platform launched in 2007, the oldest and most comprehensive product in the category. It tracks approximately 114,000 technologies across 414M+ domains, indexed by category (analytics, advertising, payment processors, CRMs, hosting, CMSs, marketing automation, ecommerce platforms, frameworks, libraries). The primary commercial use case isn't curiosity, it's lead generation. Sales teams use BuiltWith to find companies running specific technologies ("all SaaS companies on HubSpot using Intercom") and turn that signal into outbound prospect lists.
Pricing
BuiltWith pricing 2026
Pricing collected from builtwith.com/pricing (May 2026). Tier names approximate: BuiltWith renames Basic / Pro / Enterprise periodically.
| Plan | Price | Typical use | Key limits |
|---|---|---|---|
| Free single-site lookup | $0 | Curiosity / one-off lookups | Free Chrome extension · single-site only · no bulk export |
| Basic | $295/month | Solo lead-gen on a couple technologies | 2 technologies + 2 keywords · bulk export |
| Pro | $495/month | Agencies / multi-tech tracking | Unlimited technologies + keywords |
| Team | $995/month | Teams needing multi-user + larger datasets | Unlimited tech + multi-user seats |
| Team Ultra | $6,000/month | Enterprise data/API consumers | Unlimited API + full datasets · annual contract typical |
What the pricing page doesn't show
The Basic tier's "1 tech filter" is more restrictive than it sounds: many useful queries combine 2-3 technologies (e.g. "Shopify + Klaviyo + Yotpo") which forces Pro tier. Historical data (tech adoption + churn over time) is locked to Enterprise tier, a significant differentiator versus Wappalyzer that doesn't show up in the pricing table. API access gates to Pro and above. Result caps per tier matter at scale: exhausting 50K results on Pro forces upgrades.
Where BuiltWith is fair value
If your ICP is technology-defined (Shopify merchants, HubSpot customers, companies running specific stacks), BuiltWith's $495/mo Pro tier is the cleanest way to build prospect lists at scale. Wappalyzer is cheaper but tracks fewer technologies with thinner historical depth. For teams whose ICP is firmographic-defined ("SaaS companies 50-500 employees"), BuiltWith's tech-stack lens is overkill and Apollo or Cognism deliver more for less. The free single-site tool is enough for ad-hoc curiosity.
Verdict in detail
BuiltWith Pros & Cons - Summary That Actually Helps You Decide
Pulled from G2 + Capterra verified-buyer reviews (Q1 2026), filtered for substance. BuiltWith's strongest signals : detection depth, historical data, and the single-site lookup as a lead-gen funnel.
Deepest tech detection in the category
approximately 114,000 technologies tracked is materially more than Wappalyzer's ~3K or HG Insights' enterprise focus. For niche technology targeting (specific Klaviyo apps, payment processors, build tools), BuiltWith is the only tool that surfaces them at scale.
Historical tech adoption data unique to BuiltWith
The platform tracks technology adoption and churn since 2007. You can find companies that recently switched from Mailchimp to Klaviyo, or sites that just installed Stripe, high-signal triggers for outbound timing.
Free single-site tool is a brilliant funnel
Anyone can look up any website's full tech stack for free, no signup. The tool is so useful that it's become the de-facto industry reference for "what's this site running", and it converts curiosity into qualified leads for the paid product.
Per-tech-filter pricing punishes complex ICPs
If your ICP combines 4-5 technologies ("Shopify + Klaviyo + Yotpo + ReCharge + Gorgias"), Basic tier ($295/mo, 2 filters) is unusable: you need Pro ($495/mo, unlimited) or Team. For simple single-tech filters, the math works ; for sophisticated stacks, costs climb fast.
Contact data is included but not the strength
BuiltWith bundles contact data (emails, phones, LinkedIn URLs) with each detected site, but the data quality lags Apollo or Cognism: older, less verified, less mobile-phone coverage. Most teams use BuiltWith for the tech filter, then enrich the returned contacts through Apollo or Lusha.
No outbound automation: pure data layer
BuiltWith stops at the prospect list. There's no email sender, no LinkedIn automation, no campaign builder. Teams use it strictly as the top-of-funnel signal layer, then run lists through separate tools (Apollo, Lemlist, Smartlead) for execution.

Head-to-head: BuiltWith vs 1 competitor
The verdict
Who should skip BuiltWith
BuiltWith is the right tool for sales teams whose ICP is defined by technology adoption: Shopify merchants, HubSpot customers, companies running specific stacks. The detection depth (approximately 114,000 technologies) and historical data (since 2007) are genuinely unique and no competitor matches them. The platform fails as a general enrichment tool: contact data quality lags Apollo, and the per-tech-filter pricing punishes complex ICPs. For its core ICP (tech-defined outbound at scale), BuiltWith is the only tool deep enough to do the job, and the $495/mo Pro tier is defensible for multi-technology ICPs. The free single-site lookup remains a common industry reference for ad-hoc "what's this site running" curiosity.
