With respect, Pokorny's dictionary is notoriously out of date and should be used nowadays with only with extreme caution. The current standard references are unfortunately not online in digital form, although .pdfs of them exist online if you know – not wanting to openly advocate mass book piracy – what I will here euphemistically call the right places to look.
For verbs and verbal stems:
A selection of roots that form nominal stems (not fully complete, but very comprehensive of the roots that it does cover):
For pronouns and particles:
Of course, as this is the Indology list, you may already know of Mayrhofer's dictionaries specifically for Vedic and Sanskrit (there are scans of these currently on archive.org, cf.https://archive.org/search.php?query=mayrhofer).
Mayrhofer, Manfred. 1956-1980. Kurzgefaßtes etymologisches Wörterbuch des Altindischen. Heidelberg: Carl Winter Universitätsverlag.
Finally, if you have institutional access, the dictionaries in Brill's Indo-European Etymological Dictionaries Series have online versions, although currently the series is currently limited to individual languages and branches and does not allow searching entries by root etymon. https://dictionaries.brillonline.com/iedo
For Middle and Modern Indo-Aryan to Sanskrit, I would echo Eric's previous suggestion of the digital version of Turner's Comparative Dictionary of the Indo-Aryan Languages on UChicago's digital dictionaries of South Asia website. https://dsalsrv04.uchicago.edu/dictionaries/soas/
I hesitate to add to all of this that over the last year or two I've been writing a series of blog posts on my own website aimed at general audiences outlining the main Indo-European etymological resources currently available, although I haven't gotten to the Indo-Aryan and Iranic language sub-families yet. https://consultingphilologist.wordpress.com/indo-european-etymological-dictionaries/. The TL;DR version of the Indo-Aryan one would be, use the aforementioned dictionaries of Mayrhofer and Turner in conjunction with the most up-to-date root dictionaries of the LIV, NIL, and LIPP.
Apologies for the length of this email and only being tangentially helpful with the requested 'online' Indo-European etymological dictionaries, but I felt I would be remiss to not point these resources out since while Pokorny's dictionary is readily available in many different online versions, it is no longer a reliable reference work. If you need help accessing the other more recent IE root dictionaries I've mentioned here, please do not hesitate to contact me off list.
All very best wishes,

There is, e.g., an online version of Pokorny's dictionary:
Title of the print version: Indogermanisches etymologisches Wörterbuch / by Julius Pokorny (Bern et al., 1959-1969, in two volumes, the last edition known to me is the 4th edition, 2002).
Hope it helps
