FamilySearch is a great website for family research in general, with extensive records spanning all over the world. For Irish records it is nearly on par with Ancestry but it is FREE! It has all the same indexed church and civil records as Ancestry but without the need for a subscription.
All the basic Irish records you will need to search your ancestors
Free of charge
Historical and genealogical documents available to view in their catalogues
Search function is easy to use
Family tree feature
Family tree feature is basic and a bit fiddly
User messaging and searching is complicated
Extra features like 'Memories' not well developed
No DNA kits
This site is in real competition with Ancestry and Findmypast. Its records have only increased over the years and it has become a staple for DIY genealogists. It has all the core records you will find on other sites without the price. You can switch your search between countries all over the world unlike Ancestry where you may only have a subscription to the UK and Ireland records, and therefore have to upgrade to view global records. So it almost makes you wonder as to why you would need an Ancestry account?
Well, the user interface is just not on par with Ancestry, it is bland to look at and at times complicated to use. Because of this, collections and services have gone unnoticed and unused where they could have been incredibly useful. I do not want to have to go searching through every link to see what i have missed, and that is where Family search falls short.
Transcribed church records
Indexed civil records
Global records (for those ancestors who migrated)

User's family trees
*Some information on family trees can be incorrect, and I am not sure if it is just me but it seems more so than on Ancestry. The only explanation I can think of is that users are not taking the feature seriously and are just using it to log down possible matches.
*Search the catalogues under the Search tab at the top of the screen. Put in your county of choice and check the online box. There are some records that are able to be viewed that have not been transcribed. Not all are widely relevant but you might find a gem or two in them.
