BuiltWith is a server-side web crawler that identifies the technologies, analytics tools, hosting providers, and frameworks detected on any website. It maintains a database of over 50,000 technologies across millions of domains and provides historical adoption data showing when companies added or dropped specific tools. It is the most comprehensive technology coverage database available for B2B sales teams doing technographic segmentation.
BuiltWith starts at $295 per month for its Basic plan. That is a reasonable price for what it delivers, but two things drive teams to look for alternatives. First, the crawl data can be 4 to 8 weeks old on any given domain, which matters when you are trying to reach companies that recently adopted a new CRM or data stack. Second, BuiltWith does not include contact data, so it is one part of a larger workflow that most teams want to consolidate. These are the six genuine BuiltWith alternatives worth considering in 2026, with the Crawler Freshness Test result for each.

BuiltWith is not leaving teams because the data is bad. The coverage is the broadest in the market. Teams leave because of two operational friction points.
Freshness. Server-side crawls happen on a scheduled basis, not in real-time. For fast-moving SaaS companies where a CRM swap or marketing automation change happens overnight, BuiltWith's crawl data can lag by several weeks. When you are using technographic data as a timing signal (the company just adopted Salesforce, so they are probably building out a new revenue stack), stale data turns the signal into noise.
No contact data. BuiltWith tells you which 50,000 companies in your target industry use Salesforce. It does not give you a verified email or direct dial for the VP of Sales at any of them. Most teams use BuiltWith as one input into a multi-tool workflow: export the filtered company list, then enrich it with a contact database. Teams looking to simplify their stack want that enrichment in one tool.
BuiltWith's pricing from WebReveal's 2026 testing, checked September 2026: Basic at $295/month (limited technology reports), Pro at $495/month, Team at $995/month with API access.
The Crawler Freshness Test is a three-point pre-purchase evaluation that any BuiltWith alternative should pass before you commit a monthly budget to them. Freshness is the single most important differentiating factor between providers with similar coverage claims.
Test 1: Crawl Age. Ask the vendor or check their UI: when was the last time this specific domain was crawled? Pass: under 30 days. Warning: 30 to 90 days. Fail: over 90 days. SaaS tech stacks change faster than quarterly crawls.
Test 2: Detection Depth. Run your own domain and 10 known competitor domains through the tool. Compare the detected technologies against what you know is actually running. Pass: 80 percent or more of your known technologies detected. Warning: 60 to 80 percent. Fail: below 60 percent.
Test 3: Cost Per Company. Divide the monthly plan cost by the number of ICP-fit company lookups you expect to run monthly. Pass: under $0.50 per company. Warning: $0.50 to $2.00. Fail: over $2.00 per company. BuiltWith's Basic plan at $295/month with unlimited lookups typically passes this test for most use cases.

Pricing sourced from BuiltWith Alternatives 2026, TechnologyChecker, BuiltWith vs Wappalyzer vs Derrick, Derrick App, and WebReveal's 2026 testing, checked September 2026.
Wappalyzer detects technologies by analyzing page source at the moment a user visits a domain, rather than batch-crawling. For client-side technologies (JavaScript libraries, analytics tags, ad networks, CMS platforms), Wappalyzer's data is often fresher than BuiltWith's.
Where Wappalyzer wins over BuiltWith: real-time detection for high-frequency research, easier to use, and the per-month price is comparable at $250 for Pro (unlimited technology targets and basic API access) per SyncGTM's Wappalyzer review 2026, checked September 2026.
Where BuiltWith wins over Wappalyzer: 50,000-plus technologies vs. roughly 4,500, significantly stronger eCommerce technology tracking, historical adoption data showing when companies added or dropped tools, and server-side detection that catches technologies not visible in the client-side page source.
Wappalyzer's price increase note: Wappalyzer raised its entry tier from $149 to $250 per month at some point before 2026, narrowing its previous price advantage over BuiltWith. The mid-tier Business plan at $450/month adds unlimited targets and full API access. Check current pricing directly as tiers change more frequently than their older marketing materials suggest.
SimilarTech combines web crawl technographic data with advertising technology detection, making it useful for teams specifically targeting companies based on their advertising stack: which ad networks they run, which analytics platforms they use, and which retargeting providers they have installed. SimilarTech claims coverage of approximately 70,000 technologies, exceeding BuiltWith's publicly stated figure.
The key caveat: SimilarTech's pricing is custom and available via quote only. They market primarily to enterprise buyers and advertising-focused sales teams. For general technographic data use cases, BuiltWith or Wappalyzer are more accessible entry points.
Clearbit was acquired by HubSpot and rebranded as Breeze Intelligence. If your entire outbound workflow lives in HubSpot (CRM, sequences, reporting), Breeze is the lowest-friction technographic enrichment option because the data lands directly in HubSpot record fields without an export-import workflow.
The trade-off: Clearbit's technographic data relies heavily on job posting inference rather than direct web crawling, which means lower confidence for specific technology attribution. Coverage also runs lighter outside North America. Pricing is HubSpot-platform-native and quoted based on usage.
For teams outside HubSpot who need stand-alone technographic data, the $999-plus monthly price point makes Clearbit an expensive option compared to BuiltWith's $295 entry.
Apollo.io bundles technographic data with contact data, which eliminates the common BuiltWith workflow problem: you find a company list by tech stack in BuiltWith, then have to enrich it separately with a contact database. In Apollo, you filter by technology, headcount, and title simultaneously and export a contact list directly.
The trade-off: Apollo's technographic data is primarily job-posting inference, which is less reliable than direct crawling for current tech stack accuracy. A company listed as using Salesforce in Apollo may have switched 8 months ago. For exact competitive displacement use cases where precision matters, BuiltWith's direct crawl is more reliable.
For B2B prospecting teams who want a simpler stack and do not need the deepest technographic coverage, Apollo's bundled approach is a reasonable choice. See our ZoomInfo vs Apollo comparison context for how these tools differ across their full feature sets.
Regardless of which provider you choose, the workflow from technographic filter to outreach requires a verified contact layer. The gap between "companies running Salesforce" and "the VP of Sales at those companies whose email address is valid" is the gap that kills pipeline generation velocity.
For teams using BuiltWith or a direct alternative for technographic segmentation, the practical workflow is:
Step 3 is where data appending services and waterfall enrichment tools are relevant. The goal is to get from a technographic company list to a verified contact list with the fewest manual steps.
BuiltWith and its alternatives surface the companies. InboundLabs provides the contacts.
When your technographic segmentation returns a list of 2,000 companies running Salesforce in your target industry with 100 to 500 employees, InboundLabs gives you the verified contacts at those companies. Filter by title to find the economic buyer, the champion, or the technical evaluator at each account. A database of 280M verified B2B contacts with buyer intent signals layered on firmographic data. 98% email deliverability on verified contacts. Verified direct dials, not switchboard numbers.
Monthly plans, no annual lock-in. Free to start, no credit card required.

The right BuiltWith alternative depends on your primary use case. If you need real-time client-side detection, Wappalyzer is the move. If you need advertising and marketing tech specifically, SimilarTech. If you live in HubSpot and want enrichment bundled, Breeze. If you want contact data alongside technographic data and can accept job-inference accuracy, Apollo. If you need the deepest, most comprehensive technology coverage and are willing to run a separate enrichment step for contacts, BuiltWith is still the market benchmark. Run the three-step Crawler Freshness Test on any provider before committing.

Why would I switch from BuiltWith to an alternative? The two main reasons teams switch are crawl data freshness (BuiltWith's server-side crawls can be 4 to 8 weeks old for any given domain, which matters for timing-based outreach) and the lack of contact data (BuiltWith surfaces companies but requires a separate enrichment step to get contacts). Teams wanting real-time detection or a unified tech-plus-contact tool explore alternatives.
How do I test a BuiltWith alternative for data quality? Run the Crawler Freshness Test: check 20 domains you know well against the tool's output, verify the crawl age on your own domain, and calculate the cost per company lookup for your expected monthly volume. Any alternative that fails two of the three tests is not worth switching to for your use case.
Is Wappalyzer better than BuiltWith? For client-side technology detection freshness, yes. For overall technology coverage depth (50,000-plus vs. roughly 4,500 technologies), historical adoption data, and eCommerce stack tracking, BuiltWith wins. Most serious technographic data programs use both: Wappalyzer for fresh, real-time detection and BuiltWith for comprehensive historical and coverage depth.
Does Apollo have the same technographic data as BuiltWith? No. Apollo's technographic data is primarily inferred from job postings, which is indirect and less reliable for exact technology attribution than BuiltWith's direct web crawl. Apollo's advantage is that technographic and contact data are bundled in one platform. For competitive displacement use cases where you need to be certain a company runs a specific tool, BuiltWith's direct detection is more trustworthy.
What is the cheapest way to get technographic data for B2B outbound? Datanyze's entry tier starts around $29 per month and provides basic technographic data for a limited number of lookups. For teams with under 500 monthly company lookups, this is a viable starting point before investing in BuiltWith or Wappalyzer. The trade-off is narrower coverage and fewer monthly lookups.
Can I combine BuiltWith with a B2B contact database? Yes, and this is the most effective workflow for outbound. Export your BuiltWith technographic filter results as a company list, then run that list against a B2B contact database to pull verified contacts at each company filtered by relevant title. The combination gives you both the precision of technographic qualification and the actionability of verified contact information.
How often should I refresh my technographic data for outbound? Monthly is the practical baseline for fast-moving technology categories like CRM, marketing automation, and sales tools. Quarterly may be acceptable for slower-moving infrastructure technologies. For timing-signal-based outreach (reaching out when a company just adopted a new tool), you need real-time or weekly data, which requires either Wappalyzer's browser extension approach or API-based lookup at the point of account research.

What is a funding data API? A funding data API provides structured access to investment event data: company name, funding stage, round size, lead investors, and close date. Sales and RevOps teams use it to trigger outreach automatically when target accounts receive capital, since funded companies have confirmed budget and the mandate to spend it.
B2B data coverage rate is the percentage of your target account list or ICP for which a data provider can return at least one qualifying contact matching your title, seniority, and role criteria. It's distinct from total record count (how many contacts a provider holds overall) and from accuracy (what percentage of returned contacts have valid, deliverable contact details).
What is an email append service? An email append service takes an input file of contact records (typically name plus company or domain) and matches them against a proprietary database to return email addresses for records where no email exists. Quality providers also run verification before delivery, filtering out addresses that would bounce or hard-fail. B2B append is distinct from B2C append because business addresses are tied to employment status, which changes constantly.
A B2B data marketplace is a platform or exchange that aggregates data from multiple providers, typically covering contact records, firmographic attributes, technographic signals, intent data, or combinations of all four. Buyers access pre-vetted, standardized data from multiple sources without managing separate contracts with each underlying provider.
