Many people just run it paper and pencil on Zoom or Discord, TotM. Some have a cam on their dice tray.
I know for me, Foundry has modules that help organize my stuff. I have yet to buy anything beyond the initial purchase of the program. All updates are free. A bit of tech savvy helps, but there is a big community for support. The systems and sheets for many games are available for free. Content can be uploaded as scenes and even compendium packs. It helps if you have PDFs.
