About Us

A Brief History

datdota was created in 2013 by Martin Decoud. He was the sole developer until mid-2016, when Noxville took over the running of the site and relaunched it towards the middle of 2017.

The site was a PHP frontend with MySQL backend initially, using smoke and clarity (and some R scripts) to keep the parsing going, but in it's latest rewrite it was done in Grails with Postgres, using clarity2 for parsing.


We are probably the only Dota 2 stats site that's not in contravention of the Steam & Steam WebAPIs Terms of Service. Yay! Go us!

Our Thanks!

datdota wouldn't be possible without the following people and/or technologies.

Accordingly, we have developed this privacy policy in order for you to understand how we collect, use, communicate, disclose and otherwise make use of personal information. We have outlined our privacy policy below.

  • We will collect personal information by lawful and fair means and, where appropriate, with the knowledge or consent of the individual concerned.
  • Before or at the time of collecting personal information, we will identify the purposes for which information is being collected.
  • We will collect and use personal information solely for fulfilling those purposes specified by us and for other ancillary purposes, unless we obtain the consent of the individual concerned or as required by law.
  • Personal data should be relevant to the purposes for which it is to be used, and, to the extent necessary for those purposes, should be accurate, complete, and up-to-date.
  • We will protect personal information by using reasonable security safeguards against loss or theft, as well as unauthorized access, disclosure, copying, use or modification.
  • We will make readily available to customers information about our policies and practices relating to the management of personal information.

API Usage

There are various APIs available on datdota for both private (internal) and public (not-internal) use. These APIs have the same overall site Terms of Service as listed above ('datdota Terms of Service and Privacy Policy'), as well as additional API-specific terms of service (as below).

API Specific Terms of Service

  • 1 request (overall) per second.
  • Should you receive any HTTP 429 responses, your usage has exceeded the rate limit and you should reduce your usage rate, else you may be blocked.
  • Should your IP be blocked, rather contact us to fix the issue - instead of just trying to dodge the ban.
  • If you have some frontend code, for example in Javascript, that needs to pull some data off a datdota API - where possible you should proxy & short-term (~5 minutes) cache the specific data for your users. This is to reduce overall load on the API.
