Extraction
Custom spiders built with Scrapy and, for dynamic or JS-rendered sites, Playwright and Selenium. Built to keep working against active anti-bot protection and catalogs that change constantly. You own the spider's source code from day one.
Professional Services designs, builds, and maintains the extraction logic behind your data — even against active anti-bot protection, JS-rendered sites, and catalogs that change every day.
Hire the full lifecycle or just the stretch you need — every pillar is built and maintained by the same engineers, so nothing gets lost between handoffs.
Custom spiders built with Scrapy and, for dynamic or JS-rendered sites, Playwright and Selenium. Built to keep working against active anti-bot protection and catalogs that change constantly. You own the spider's source code from day one.
Scheduled or on-demand pipelines that orchestrate every spider as one coordinated flow, plus the cleaning, normalization, and transformation that gets raw output into the format you agreed on.
Homogenizing data across sources — unifying categories or SKUs from different sites — enriching it against your business rules, and validating every delivery against the acceptance criteria we agree upfront.
Automatic checks on every run, alerts before you notice a problem, and a maintenance retainer sized to how much your target sites actually change — not a flat rate across every client.
The same five-step process for every engagement, so the estimate you get upfront is the one that holds once the spider is live.
You share the target URLs, the fields you need, how often, and what counts as a successful delivery. Our engineers review it before anything gets estimated.
Every engagement is sized with the same technical method — real site risk and spider complexity, not a guess — and you sign a Statement of Work before development starts.
Engineers build and test the spider against the acceptance criteria agreed in scoping, before it ever reaches production.
Every delivery is validated against your acceptance criteria, then handed to the maintenance team with a full technical brief — known risks, baseline metrics, and everything they need to keep it running.
A monthly retainer keeps monitoring, fixes, and reporting running for as long as you need the data — sized to your site, reviewed every quarter as things change.
No data from a scheduled run, with no workaround.
Below 95% of baseline, or stale by 2× the agreed frequency.
Non-critical fields degraded, or a workaround already in place.
Questions, documentation, or cosmetic requests.
Proactive monitoring checks every run automatically and alerts our team before you have to file a ticket.
Infrastructure-agnostic: the same SLA applies whether your spiders run on Bitmaker Cloud, your own infrastructure via Estela Commercial Support, or anywhere else you host them.
Professional Services is for building and maintaining spiders — not for running ones that already work, or for receiving a finished dataset.

Every quote is scoped to your target sites — there's no published flat rate because the real cost depends on how hard those sites are to keep up with.
Tell us the target sites and we'll scope the spiders, the pipeline, and the maintenance retainer together.
