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