At a glance

Who should choose which

Start with the question your team needs to answer. Write down the input you have, the output you need and the person who will use it. A useful evaluation task should be specific enough for two colleagues to repeat independently and compare their findings. Use the same task during each demonstration.

• Research requirements: Define whether you need website technology information, account attributes, matching products, selling domains or competitive analysis. Prepare a small set of familiar examples and check the returned information against what your team already knows. Keep a separate list of essential fields and optional fields.
• Team size and responsibilities: Count the people who will search, export, review and maintain the data. Ask which permissions each person needs and who will manage access. Include the time required to train users and review their work in your purchasing discussion.
• Channels and handover: Decide where research will go after selection, who will qualify a potential lead and which team receives it. Define the fields and context needed for that handover. For targeting preparation, see the ICP targeting guide.
• Contract and usage terms: Request the billing schedule, cancellation terms, usage limits and rules for unused credits in writing. Estimate a normal month and a busy month before choosing a package. Separate the subscription amount from implementation effort and any additional purchases your workflow requires.
• Reporting and practical evaluation: Ask for a demonstration using your own research question. Review the resulting records, their usefulness and the steps needed to repeat the work. Define your acceptance criteria before the demonstration. The ICP definition framework offers another starting point for documenting your target accounts.

Keep the evaluation connected to your wider B2B lead generation plan. Agree on the decision criteria with sales, marketing and operations before collecting proposals. Record unanswered questions separately so an attractive demonstration does not replace the checks your team needs to complete.

BuiltWith in detail

BuiltWith is the reference tool for this comparison: its product suite covers sales intelligence, lead generation and market analysis for web technologies, alongside an API for automated technology lookups. It also offers live feeds using WSS endpoints to bring live data into a customer's own product or platform.

Its documented capabilities align with buyers evaluating web technology research and automated technology lookups. For an evaluation, prepare a website list and specify the exact information you expect to receive. If your project involves a live feed, ask your technical team to document its receiving system and refresh requirements before the demonstration.

Wappalyzer in detail

Wappalyzer's Pro plan focuses on filtering one technology into multiple lists, while Business supports building lists across combinations of technologies. Its Acquia Cloud Platform CDN page lists 1,100 tracked websites and offers company and contact details within that group.

The free account provides a way to try website research with 50 monthly technology lookups and sample lead lists. The free account description also includes email verifications and 5 website alerts. Buyers whose research starts with a particular technology can compare that requirement with Pro's single-technology list scope. Before purchasing, choose a target technology and decide what would make a resulting company record useful to your team.

HG Insights in detail

HG Insights brings technographics, firmographics and behavioral signals together through an account intelligence data fabric. It describes its Revenue Growth Intelligence platform as purpose-built to support GTM strategies. That combination aligns with buyers looking for those account data categories in one platform.

For your evaluation, list the account attributes your team uses today and the questions each attribute helps answer. Ask for a demonstration of those specific questions. Have sales and operations review the same examples so both teams can assess whether the information fits their daily work.

TheirStack in detail

TheirStack describes an MCP server that lets AI assistants query its data, together with Agent Skills that turn a product URL into searches grounded in live counts. This makes it relevant to a buyer specifically evaluating AI assistant access to data and product URL driven searches.

The monthly API packages shown above range from 1,500 credits at $49 to 500,000 credits at $1,200. Build a written estimate of your intended requests before choosing a package. Ask how your actual requests consume credits, then compare the estimate with a representative trial task. Include the person responsible for maintaining the connection in that evaluation.

Store Leads in detail

Store Leads supports exporting data directly from a global product search. When exporting, users can choose the products matching the search or the domains selling those matching products. Its documented export choice fits a workflow that starts with product search results and needs either product records or the associated selling domains.

Define the required output before the demonstration. Bring an example product query and specify whether the next task needs individual products or domains. Ask the person receiving the export to review the result and confirm that it contains the information needed for the next step.

Similarweb in detail

Similarweb Web Intelligence is an AI-powered competitive intelligence platform tailored to business goals. Similarweb also allows its API to be purchased as a standalone product without a full platform subscription. Those documented options fit buyers considering competitive intelligence through a platform or separate API access.

The reviewed pricing page directs buyers to talk to sales. Prepare a concise description of your research goals and preferred delivery format before requesting a proposal. Ask for the proposed scope and commercial terms together, so your team can assess the purchase against the same requirements used during the demonstration.

How we compared
