Crawlee Framework: Build Production-Grade Custom Scrapers
Your homegrown scrapers keep breaking, losing pricing and competitor intel, and pulling juniors into endless firefights. The cost never shows as a line item, only as late feeds, angry stakeholders, and engineering time that should have shipped product.
We build Crawlee-based production scrapers with retries, proxy rotation, and queues so fragile scripts become reliable data pipelines your team can operate.
Sound Familiar?
These are the exact issues CTOs and ops leads bring us before a Crawlee rebuild:
- Homegrown scrapers break after every target-site redesign, and nobody owns the fix queue
- Junior developers spend evenings restarting failed runs and patching brittle selectors
- Price and competitor feeds go silent for days before anyone notices the gap
- Retries are naive: failed requests burn proxies and still leave half-empty datasets
- Ops cannot hand scrapers to anyone else; the original author is the only person who understands them
Site redesigns and anti-bot escalation are accelerating. Industry analyses put yearly maintenance at 20–40% of the original build effort, while datacentre block rates on top e-commerce targets now sit around 71–78%. Fragile scripts fall behind faster than your team can patch them.
What Production Crawlee Scrapers Actually Deliver
Target changes → scraper recovers → dataset completes → ops sees the alert only when humans are needed.
Sources Defined
Pricing pages, directories, or competitor catalogues scoped with field contracts and success criteria
Crawlee Scraper Built
Queues, retries, proxy hooks, and extraction layers on the Crawlee framework, not a brittle script
Runs Recover Themselves
Failed pages retry; queues resume after crashes; proxies rotate without burning the whole job
Data Pipelines Ops Can Run
Complete datasets land on schedule, with alerts and runbooks your team can operate
Everything You Need for Maintainable Custom Web Scrapers
Crawlee Framework Scrapers
Production scrapers on the Crawlee open-source framework (Apify Crawlee), not one-off scripts. Request queues, storage, and crawler lifecycles are built in.
Automatic Retries & Backoff
Failed pages retry with controlled backoff instead of flaming out or retry-storming your proxy pool into expensive waste.
Proxy Rotation Ready
Session-aware proxy rotation hooks so protected targets stay reachable without rewriting the whole scraper when IPs burn.
Persistent Request Queuing
Queues survive crashes and restarts. Overnight jobs resume where they left off instead of starting from scratch at 03:00.
Maintainable Extraction Layers
Selectors and field contracts structured so a site tweak is a small change, not a rewrite. Your team can own the scraper after handoff.
Monitoring & Dataset Checks
Run status, fill-rate checks, and alerts so silent selector drift surfaces in minutes, not when sales discovers stale pricing on Monday.
What We Specialise In for Crawlee Engagements
From 12 Hours/Week Firefighting to 2 Hours/Week Review
How a retail pricing team replaced brittle scripts with Crawlee production scrapers and recovered engineering capacity.
The Fragile Scripts
- Two engineers spent mornings restarting failed overnight price crawls
- Every competitor redesign meant 1–3 days of selector patching
- Naive retries burned proxy budget while datasets stayed incomplete
- Pricing acted on stale competitor sheets several times a month
- Only the original author could safely change the scrapers
The Crawlee Pipelines
- Crawlee scrapers with persistent queues resume after crashes
- Controlled retries and proxy sessions cut wasted bandwidth sharply
- Fill-rate alerts catch silent selector drift before pricing notices
- Competitor sheets arrive complete on the morning schedule
- Ops owns runbooks; engineers only touch extraction when sites change

Frequently Asked Questions
What is the Crawlee framework and why use it for custom scrapers?
Crawlee is Apify's open-source scraping framework for Node.js and Python. It ships request queues, automatic retries, proxy session management, storage, and browser or HTTP crawlers under one API. We use it so production scrapers are maintainable systems rather than brittle one-off scripts that only the original developer can fix.
How is this different from fixing our existing scrapers or adding proxies?
Proxy rotation helps when IPs get blocked. It does not fix brittle selectors, missing queues, silent data gaps, or scrapers nobody else can operate. This engagement rebuilds (or newly builds) scrapers on Crawlee so retries, queuing, and maintainability are first-class, not bolted on after another outage.
Will our team be able to run these scrapers after delivery?
Yes. We design for handoff: clear structure, runbooks, monitoring, and extraction layers that a mid-level engineer can update when a target site changes. The goal is a data pipeline ops can own, not a black box that only WebFootprint understands.
Can Crawlee scrapers deploy on Apify or our own infrastructure?
Both. Crawlee runs anywhere Node or Python runs, and it deploys cleanly as Apify Actors when you want cloud scheduling, Apify Proxy, and dataset storage. We match hosting to your ops model, compliance needs, and scale.
How long does custom Crawlee scraper development take?
A focused production scraper for one to three well-understood targets typically takes 2–4 weeks from scoping to stable runs. Multi-source estates with CRM or warehouse delivery, monitoring, and documentation take closer to 4–8 weeks. We measure success rates on your targets before calling it done.
How much does production scraper development cost?
Focused Crawlee scrapers for a small target set start from around R25,000. Multi-source production estates with retries, queues, proxy strategy, monitoring, and CRM or warehouse delivery typically range from R45,000 to R90,000. Teams spending 8+ hours a week on scraper firefighting usually recover the project cost within 2–4 months from engineering time alone.
Turn Fragile Scrapers into Pipelines Your Team Can Run
If engineering still patches broken scrapers every week, you are paying a maintenance tax that production-grade Crawlee development is designed to remove.
Tell us which targets matter, how often scrapers fail, and what pricing, product, or ops depends on the data. We will show you what a maintainable Crawlee estate looks like for your stack.
