Sold by Zinn Digital
Custom Python or Node.js web scrapers built for real-world sites, handling JS rendering, anti-bot defences and multi-page crawls, with clean CSV, JSON or database output delivered within 2 to 10 days.
Scrapers built for real sites, not demos
Production-ready data extraction tools are built in Python or Node.js for product catalogues, directories, marketplaces and dynamic single-page applications. Output arrives as CSV, JSON, or written straight into your database.
What is covered
Why it holds up
Many scrapers work once in testing and fail the moment a site changes its markup, blocks a user agent, or adds new protection layers. Builds rely on resilient selectors, retry logic, proxy fallback and clear logging, so when a selector breaks or a page returns an error instead of data, you see exactly which records failed and why, rather than getting silent empty rows.
Tools used
Python (BeautifulSoup, Scrapy, Playwright, Selenium, Requests) and Node.js (Puppeteer, Cheerio, Playwright, Axios) for scraping; rotating proxies and user-agent rotation plus headless browser fingerprinting for anti-bot work; storage across CSV, JSON, Excel, Google Sheets, PostgreSQL, MySQL, MongoDB, SQLite and Airtable; scheduling through cron, GitHub Actions, AWS Lambda, Vercel Cron or Railway; infrastructure on Docker, VPS providers, AWS or Render.
Testing before handoff
Each build runs a dry pass on a small sample first, then a full run with a success and failure summary. Output is checked against the expected schema, with missing fields, duplicate rows and parse errors flagged before delivery.
Ownership
Source code and scraper credentials pass fully to you on final delivery. A non-disclosure agreement is available on request for sensitive or competitive data projects.
Timelines
Basic ships in 2 to 3 days, Standard in 5 to 7 days, and Premium in 10 days.
What is needed from you
Send over the target site and field list, and a working preview scraper can be ready within 48 hours, before any payment is required, so you can see real extracted data from your own target first.

No account needed first — yours is created at checkout. We hold the money until you accept the work.
In many cases, yes. We combine proxy rotation, user-agent variation, throttling and headless browser rendering to get past common blocks. Sites running heavier protection services can push up the cost, so we review the target first and tell you whether it fits standard pricing or needs a custom quote.
Scraping publicly available pages is generally permitted in most places, though it depends on site terms, the data involved and your intended use. We only work with public pages, do not get around paywalls, avoid collecting personal data, and will not breach explicit anti-scraping terms without your written approval and legal clearance.
Page structures do change, and selectors can stop working as a result. Every scraper includes structured error logging so you are notified as soon as a field stops returning data. Standard and Premium add resilience features such as fallback selectors and alerts to limit breakage, and we cover any layout-related fixes for free during the 14 days after delivery.
Yes, using Puppeteer, Playwright or Selenium to handle single-page applications, lazy loading and infinite scroll. This is part of the Standard and Premium packages; Basic is limited to static HTML.
Yes, for accounts you own or are authorised to use. Session handling, cookie management and form submission are included with Premium. Share any credentials through a secure channel; we do not retain them beyond the project.
We offer two approaches: a manual-solve pause where you step in, or a third-party CAPTCHA-solving service at your own cost. This is built into Premium and can be added to Standard.
Yes, Premium supports scheduled runs through cron, GitHub Actions, AWS Lambda or Vercel Cron. You choose the frequency, whether daily, weekly, monthly or another cadence, and each run logs its results with optional failure alerts.
Rate-limit handling is standard: request throttling, exponential backoff on 429 and 503 responses, and concurrency tuning to stay within limits. Both Standard and Premium include this logic in full.
Yes, direct inserts into PostgreSQL, MySQL, MongoDB, SQLite or Airtable are supported. Database output is part of Premium, while Standard covers CSV, JSON and Google Sheets.
There is no fixed ceiling; it comes down to site rate limits and the size of the proxy pool available. We have run jobs pulling well over 100,000 records across several days. For very large crawls we suggest proxy rotation and scheduled runs to avoid detection thresholds.
You receive full ownership at final delivery, including source code, credentials, deployment configuration and all scraped data, with no licensing restrictions, ongoing fees, or lock-in.
Each scraper is first run against a small sample, then a complete run. The output is checked against the expected schema, and missing fields, duplicate rows and parsing errors are flagged before handover, together with the error log and a summary of successes and failures.
