Why Contao?


Re­gard­less of whether you want to run mul­ti­ple web­sites in one Con­tao in­stal­la­tion, main­tain a web­site in mul­ti­ple lan­guages or need de­tailed us­er per­mis­sions to work on a web­site col­lab­o­ra­tive­ly – Con­tao has ev­ery­thing on board by de­fault. Fur­ther­more, you can en­hance its func­tion­al­i­ty with ex­ten­sions to fit your needs.

GDPR compliant

Con­tao is com­pat­i­ble with cur­rent laws and es­pe­cial­ly the GDPR. All da­ta pro­tec­tion mea­sures are im­ple­ment­ed by de­fault, for in­stance, Con­tao us­es the dou­ble opt-in method for all sub­scrip­tions and reg­is­tra­tions and it keeps a log for the legal­ly re­quired stor­age pe­ri­od.

SEO ready

You can ad­just the ti­tle, the de­scrip­tion and the ro­bots me­ta tag of each page. Redi­rects and er­ror pa­ges al­ways send the cor­rect HTTP sta­tus code. In ad­di­tion, Con­tao us­es schema.org to tag con­tent for search en­gines and it au­to­ma­ti­cal­ly ge­ne­rates an XML site­map that can be sub­mit­ted to Google, Bing and other search en­gines.


In Con­tao, you can sort el­e­ments via drag and drop, copy and paste them via clip­board and even ed­it mul­ti­ple records at once. Ev­ery change is au­to­mat­i­cal­ly stored as a new ver­sion, so you can go back in his­to­ry at any time.


Con­tao is com­pat­i­ble with Var­nish and oth­er HTTP caches and it sup­ports mod­ern tech­nolo­gies such as HTTP2, de­ferred im­age re­siz­ing and ESI. Even with big in­stal­la­tions with hun­dreds of thou­sands of pages, Con­tao re­main per­for­mant and de­liv­ers your web­site in a flash.


Con­tao us­es mod­ern pass­word hash­ing al­go­rithms and sup­ports se­cur­ing us­er ac­counts with 2-fac­tor au­then­ti­ca­tion. More­over, us­er ac­counts are locked au­to­mat­i­cal­ly if there are too many failed lo­gin at­tempts.
