There are some almanacs available online. Without the need for completeness:
The "official" online almanac on the USNO website is currently shut down for maintenance.
ReedNavigation.com operated by Frank Reed is also a source of many tools, workshops and classes. He has an excellent mobile app, GPS Anti Spoof for learning and practicing sextant handling. His online almanac can be found here and also has an USNO web app clone .
Henning Umland's page is known for his start book A Short Guide to Celestial Navigation enlightening the theory, and also has some Javascript programs: Freeware.
A more complex application called Astron is for complete sight reduction solution but still has almanac data. Their Bygrave slide rule emulator is worth a try too.
Below is a modified version of Henning Umland's online almanac (ZIP 0.3 MB). The modifications are:
GHA of Aries is added to the display (it was calculated in the original but for some reason was not displayed.)
GHA and declination values are displayed in decimal moas instead of seconds of arc. This is more convenient for a navigator.
Initial values are put into the input fields for convenience. The applied ΔT=69.5s is a good estimate for the end of 2020 and probably for the whole 2021.
