The Worldometer pages have real time data on confirmed cases and mortality by country here. You can click through to country level data and charts. There are also pages with data on additional data on age, sex, pre-existing conditions etc.
The John Hopkins tracker isn't quite as real time but has a good visualization of cases around the world.
WHO daily situation reports - which give complete day by day tables - including whether there are cases of local transmission in any country - can be found here.
