Custom web crawlers

What's a crawler?

A Web crawler is a computer program that browses the World Wide Web in a methodical, automated manner or in an orderly fashion. Other terms for Web crawlers are ants, automatic indexers, bots, Web spiders, Web robots, or—especially in the FOAF community—Web scutters. [Wiki Reference]

Crawlers range in scale, from small ones that only fetch a couple hundred URLs, to web-scale beasts like the GoogleBot that indexes a sizable portion of the entire Internet.
 
Our crawler experience
Building crawlers is our passion and expertise. We have crawled and extracted data from websites ranging from the mundane to the insanely difficult - even through site with javascript navigation. Crawler can be python-based and work autonomously or php-based and work by user/manual trigger. We can also implement drupal-based crawlers that can work as a module that are triggered from cron. Other programming languages can also be used - in case there is an explicit requirement.
 
How can we be of service
If you need some data extracted or some websites crawled but don't have the expertise or experience, then we can definitely be of assistance.
 
We could work it one of 2 ways:
  • Outsourced model

In the outsourced model, we develop and run the crawls, then extract the data and present it to you as a deliverable in a predescussed format.

Pros: No infrastructure costs required on your end, and no crawl or programming expertise required. You need only MS Excel to read csv/tsv files or a MySQL database to read the data - local or remote. Lower costs as you only for the deliverable.
Cons: No access to source-code.

 

  •  Consulting model

In the consulting model, we function as a consultant to your company and you own the intellectual property we create in the form of the crawler. We develop the crawler and install it on your own servers.
 
Pros: You own the source code and have total control over the crawls.
Cons: More costly. Some technical and/or programming expertise may be required to run crawls.

Don't hesitate to send us a message and discuss your needs.
