Fuel your AdTech, Cybersecurity, and Market Intelligence platforms with the world's most comprehensive URL categorization database. IAB & Web Filtering taxonomies, company data, tech stacks, and more.
Pick the line that sounds like your problem — each one goes straight to the product that solves it. Our offline databases live here; our real-time API and specialized classifiers live on our sister platform, websitecategorizationapi.com.
Download pre-classified domain datasets — from 1 million up to 120 million domains — with IAB categories, web filtering tags, personas and popularity data. Everything runs on-premise inside your infrastructure, so no lookup ever leaves your network, with regular update deliveries. Redistribution licensing is available if the data powers a product you sell to your own clients.
Our API returns IAB Content Taxonomy categories — the industry standard for AdTech — in real time, making it a drop-in fit for contextual targeting, brand safety and pre-bid filtering pipelines. The ad-tech intelligence layers (MFA detection, COPPA scoring, audience segmentation) run on the same call path.
Browse a live sample of the database with every field visible, filter and search it in your browser, or download a free 1,000-row CSV. You can also categorize any single domain on the spot to sanity-check our accuracy against sites you know well.
Our web filtering taxonomy covers adult content, gambling, drugs, weapons, violence, malware and the other categories acceptable-use policies are built on. Take it as an offline database for zero-latency local lookups, or call it in real time for the long tail of unknown domains.
A low-latency REST endpoint returns IAB v2/v3 categories, web filtering labels and persona signals for any URL on demand — the right fit for pre-bid filtering, inline gateways and enrichment pipelines. Monthly plans or pay-as-you-go credits, no subscription required.
We run bulk categorization jobs of any size — one-time or recurring — in your taxonomy of choice. For smaller or one-off batches, pay-as-you-go credits work with no subscription. Tell us your list size and requirements and we'll come back with a quote and turnaround time.
Score any URL 0–100 for MFA risk — ad-stack forensics, page-structure analysis, AI content-authenticity judgment and domain intelligence from published MFA research, with every underlying signal returned so exclusions survive a challenge from a seller or an auditor.
One call returns a children's-privacy risk score built from five dimensions: child-directed content detection, personal data collection, tracking and persistent identifiers, missing privacy controls, and content appropriateness — for one URL or a continuous sweep of your whole inventory.
Infer who would read a page from the content itself — demographics, purchase intent, life stage, B2B firmographics and 1,667+ interest personas. Page-level, cookieless, and privacy-safe by construction, available per URL or precomputed across the corpus.
Describe your ICP in plain language — for example, "all AI companies run by a solo founder, operating as a SaaS business, less than two years old, and hiring based on their careers page" — and we'll extract exactly those domains from the 102 million domain database.
Block AI tools selectively or wholesale with a maintained AI-domain blocklist, and detect the technology stack of any site — ad-tech, CMS, analytics, consent platforms — or pull the full list of domains running a given technology.
Custom taxonomies, unusual volumes, on-premise deployments, redistribution licensing — describe what you're working on and we'll come back within one business day.
