Our Cromwell scraper extracts complex technical tables, tiered pricing structures, and stock availability across the entire MRO catalogue. Built with proxy rotation and JavaScript rendering to handle dynamic page elements.
Extract complex HTML tables into structured key-value pairs. Normalise attributes like length, diameter, and material across different brands.
Capture base prices, VAT calculations, and bulk discount tiers for large volume procurement analysis.
Monitor inventory availability, specific stock counts, and estimated lead times for out-of-stock items.
Extract direct URLs for Material Safety Data Sheets (MSDS) and technical PDF documents associated with PPE and chemicals.
Map private label brands like Kennedy and Sherwood alongside premium manufacturers like Facom and 3M.
Track product visibility and organic positioning for high-volume MRO keywords.
Crawl entire category trees to build a complete map of the industrial supply taxonomy.
Run daily or weekly diffs. Only receive records where prices, stock levels, or specifications have changed.
Push structured data directly into your analytical environment via S3, BigQuery, or Snowflake.
Brief in. Clean data out.
Provide category URLs, brand lists, or specific SKU sets. We design the extraction schema together.
We configure Scrapy / Playwright crawlers, proxy rotation, and session management for cromwell.co.uk.
Schema validation, null-rate checks, and technical attribute normalisation before full launch.
JSON / CSV / Parquet pushed to your S3 bucket, BigQuery dataset, or Snowflake stage on agreed cadence.
Industrial catalogues feature deep category trees and complex specification tables. Here is how we ensure data quality.
B2B distributors use edge protection to block automated traffic. Our crawlers route requests through UK-based residential IPs with realistic browser fingerprints to maintain high success rates without triggering rate limits.
MRO products have dozens of technical attributes presented in variable HTML tables. Our pipeline parses these tables into clean JSON objects, standardising field names so 'Overall Length' and 'O/A Length' map to the same column.
Bulk discount tiers and real-time stock levels often load via asynchronous JavaScript requests. We use Playwright to execute page scripts and capture the exact data presented to a human buyer.
For catalogues exceeding 400,000 SKUs, full daily exports create unnecessary storage costs. We hash field values and only deliver records where price, stock, or specifications have changed since the previous run.
Every run emits structured logs. We alert on null-rate spikes, missing price fields, and layout changes. Our engineers update selectors before your downstream processes fail.
Industrial distributors track Cromwell pricing on exact-match SKUs to adjust their own margins and promotional strategies.
Large manufacturing firms ingest catalogue data to build internal procurement systems and identify the cheapest suppliers for bulk orders.
B2B marketplaces scrape technical specifications and datasheet links to populate their own product detail pages with accurate attributes.
Analysts track stock availability and lead times across critical PPE and tooling categories to predict supply chain bottlenecks.
Tool manufacturers monitor category search rankings and shelf-space allocation to evaluate brand visibility against private labels.
Brands audit retail prices against their wholesale costs to estimate distributor margins and enforce pricing policies.
"Cromwell houses one of the most comprehensive MRO catalogues in the UK, but extracting technical specifications requires structured pipeline engineering."
Industrial distributors often rely on outdated manual scraping methods. DataFlirt automates the extraction of complex specification tables, stock levels, and tiered pricing structures using residential proxies and full JavaScript rendering. Your engineers get clean data, not maintenance tickets.
Everything supported by our cromwell.co.uk scraper — rendered SPA elements, auth walls, rate-limit evasion and beyond.
Open-source tooling on proven cloud infra — no vendor lock-in, full observability.
Scrapy handles crawl orchestration, deduplication, and retry logic. Playwright handles JavaScript rendering, cookie sessions, and interaction flows. Combined via scrapy-playwright middleware.
We maintain pools of residential ISP proxies across UK regions. Rotation happens per-request with sticky sessions where required. IP score monitoring prevents blacklisted pool contamination.
Pipelines run on AWS Lambda (burst) and ECS (sustained). Airflow handles scheduling, dependency management, and SLA alerting. All state stored in managed Postgres.
Data delivered to where your team already works — no new tooling required.
About cromwell.co.uk scraping, legality, and pipeline operations.
Ask us directly →Scraping publicly available information from Cromwell is generally permissible under UK law. DataFlirt targets only public, non-authenticated product, pricing, and specification data. We do not extract personal data or circumvent authentication walls. Clients should review Cromwell ToS and consult legal counsel for specific use cases.
MRO products have highly variable attributes. We parse the specification tables dynamically into JSON objects. We can also apply custom mapping logic to normalise field names so your database receives consistent schema regardless of the manufacturer.
We can configure pipelines to run at your required cadence. Full catalogue refreshes typically run weekly, while targeted SKU lists can be monitored daily or hourly for critical stock level changes.
Yes. We can scope the pipeline to target specific brand pages (e.g., Kennedy, 3M, DeWalt) or specific category URLs rather than crawling the entire site.
Our smallest packages start at a defined SKU list (typically 5,000 to 20,000 SKUs) with weekly delivery. For full catalogue extraction, we price based on volume and delivery frequency.
Absolutely. We provide a sample run of up to 500 SKUs or specific category pages as part of the pre-engagement scoping process. You can validate schema fit and data quality before signing any contract.
20-minute scoping call. Pilot dataset within the week. Production within two. Whether you need a one-off catalogue dump or a continuous price-monitoring feed across 400K SKUs. We scope, build, and operate the pipeline. Tell us what you need.
