TechnologyChecker

TechnologyChecker is a technographic intelligence platform for B2B sales, go-to-market, and market-analysis teams. It is best for teams that want technology research, historical change signals, and matched decision-maker contacts in one workflow. Its breadth is a strong draw, but capped lookups make tier selection important for sustained prospecting.

Overview

The platform combines technology detection with company profiles, historical timelines, technology-intent signals, contacts, and audience exports. It aims beyond a static list of website tools: teams can use the signals to identify adoption, churn, and replacement activity, then connect those patterns to contacts or advertising audiences. That combination is most useful when technology choices are part of a defined sales or market-analysis process.

Key features

TechnologyChecker says it detects more than 40,000 technologies across 29.9 million live business domains. It uses HTTP headers, JavaScript fingerprinting, HTML parsing, and DNS lookups, and says its full-stack detection includes backend infrastructure and standalone tools such as n8n, Zapier, Make, Airtable, Notion, and Coda. This broader scope suits teams investigating operational tools as well as conventional website technologies.

Historical timelines reach roughly 20 years, drawing on recent crawls and public web archives. That can help analysts examine how adoption and replacement patterns develop over time, although the Free plan’s six-month history is a sharply reduced window. Real-time signals cover technology adoption, churn, and replacement changes. Verified decision-maker contacts matched to technology signals and audience exports for LinkedIn, Facebook, and Google Ads give the research practical prospecting and campaign uses.

The technographic API provides 29 REST endpoints for detection, company data, category share, and adoption, churn, and switch signals. Paid tiers include API access and list CRM, LinkedIn, and Zapier/Make integrations. These options suit teams incorporating technographic data into existing processes rather than relying only on the web interface.

The Trust Center says the service is SOC 2 audited and compliant with GDPR, HIPAA, and KVKK, and aligned with CCPA. It lists TLS 1.2+ encryption in transit, AES-256 encryption at rest, and role-based access control—relevant safeguards for teams handling business data and contacts.

Pricing

TechnologyChecker uses a freemium model, with paid plans from $89/mo. The Free plan costs nothing and includes 100 lookups per month, six months of historical data, single-result CSV export, basic company enrichment, and basic email support. It is a useful small-scale evaluation tier, but its limited history and one-result export make it a poor fit for regular bulk research.

Pro costs $89 a month, billed $890 a year. It raises the allowance to 10,000 lookups per month and five years of history, and adds verified contacts, bulk lookups, CRM integrations, API access, and priority email support. This is the practical starting point for teams running ongoing prospecting or integrating lookups into a sales workflow. The annual billing amount matters: the stated monthly price is not the annual total.

Scale costs $249 a month, billed $2,490 a year. It includes 50,000+ lookups per month, 20 years of history, SSO and SCIM, and a dedicated success manager. It fits larger teams that need the deepest timeline and higher volume, along with identity-management features and dedicated support. Enterprise has custom pricing and includes 500,000 credits, custom volume, higher throughput, and dedicated support; it is aimed at organizations whose needs exceed the standard tiers.

Lookups pause when a monthly plan limit is reached, until the next billing cycle or an upgrade. That hard stop can disrupt a time-sensitive campaign, so teams should allow for their peak monthly usage rather than budgeting only for routine volume. A free trial is also offered.

Platforms

TechnologyChecker is available on the web, through an API, and as an extension. The product site links to a Chrome extension in the Chrome Web Store. This mix gives teams a browser-based option, programmatic access, and an extension workflow.

Who it's for

TechnologyChecker is a strong fit for B2B sales and GTM teams that want to pair technology-based targeting with contacts, bulk research, and CRM or API workflows. Market analysts can make use of the long historical timelines and category-share and change-signal endpoints. It is less suited to occasional users who need only a few lookups, or to teams likely to hit a monthly cap without room to upgrade.

Pros and cons

Pros: Broad detection coverage and multiple detection signals reach beyond standard website technology checks.

Pros: Historical data, real-time change signals, and technology-matched contacts connect market research with prospecting.

Pros: Pro and Scale offer progressively higher lookup limits, deeper history, integrations, and support options.

Cons: The Free tier’s 100 monthly lookups and six-month history are restrictive for ongoing research.

Cons: Lookups stop at the monthly cap, which can interrupt work until renewal or upgrade.

Cons: Pro and Scale are priced with annual billing amounts, while Enterprise uses custom pricing.

Alternatives

Compare technographic data software if you want to weigh this product against the wider category. Choose Wappalyzer if a free tier with 50 technology lookups and 50 email verifications per month, plus website alerts and sample lead lists, better matches a smaller workflow. Datanyze is an alternative with a 90-day trial and extension and web access, though its listed plans use credits and do not show prices.

Consider B2BEnrich if person and company enrichment are the priority: its free tier includes 50 credits per month and is positioned for testing and small projects. PredictLeads is another option for API or self-hosted workflows, with usage-based API-call plans. Pursued.io may suit a small web-based team starting with 50 free credits and one team member.

StackDetect is an alternative with API, extension, and web access and a free allowance of 50 technology lookups per month. TheirStack offers an API plan and a free tier with monthly company and API credits, search-result pages, and workspace invitations. BuiltWith is worth considering if its free allowance of 10 detailed lookups per day or its Advanced plan’s unlimited detailed lookups better suits your lookup pattern.

Verdict

Choose TechnologyChecker if your B2B team needs broad technographic coverage tied to historical and real-time change signals, matched contacts, and workable API or CRM connections. Its strongest case is the combination of research depth and prospecting utility. Look elsewhere if your usage is occasional, your budget depends on a small free quota, or a hard monthly lookup stop would put campaigns at risk.
