Yes, in recent times, especially for those unable to travel (like NRIs, elderly, or due to health/work constraints), some Pandits and organizations in Varanasi]i offer online Shradh services.
How it works: You provide the necessary details (ancestor names, Gotra, etc.). The Pandit performs the rituals (Pind Daan, Tarpan) on your behalf at the designated Ghat in Varanasi at an agreed time. Often, this is done via live video call (like Zoom, WhatsApp video) so you can witness and participate remotely. They may also send you a recording afterwards.
Reliability: While convenient, ensure you choose a reputable and trustworthy service. Check reviews, ask for references if possible, and confirm exactly what will be performed and how you can participate/verify it. While physical presence holds immense significance, performing the rites remotely with faith is certainly better than not performing them at all, as per interpretations of scriptures like the Garuda Purana allowing rites by proxy
