Why Keldin

Reliable collection, built for you

Scraping is only valuable if it lasts and fits your context. That's what we focus on.

Reliability & anti-blocking

Rotating proxies, captcha handling, stealth and controlled pace: robust scrapers that hold up against protections.

Tailor-made

Every solution is designed for your precise need, your sources and your format. Never a generic tool.

Responsive & close

A direct technical contact who knows your project and reacts fast when a site changes.

Reliability

Built to get past protections

Collecting web data is mostly about lasting against protections. Four pillars keep our scrapers reliable over time.

  1. Rotating proxies

    Requests are spread across a continuously rotating pool of addresses to avoid blocks.

  2. Captcha & protections

    Detection and handling of the most common captchas and anti-bot mechanisms.

  3. Controlled pace

    A controlled, stealthy request rate that respects the sites we consult.

  4. Reliable data

    Quality control on the output: complete, clean and structured data.

Our method

A scoped project, from need to data

A simple, transparent approach designed to deliver usable data without friction.

  1. 01

    Scoping

    Together we define the sources, the useful data, the volume, the frequency and the delivery format.

  2. 02

    Design

    We develop the right extractor and infrastructure, with anti-bot handling and quality control.

  3. 03

    Delivery

    You receive your data in the chosen format: file, API, database or dashboard.

  4. 04

    Follow-up

    Maintenance, monitoring and improvements depending on the plan, so collection stays reliable over time.
