The rollout for the COVID-19 vaccine is in full swing across the United States, but access to it has varied widely between states, counties, and even clinics. Figuring out how and where to get the vaccine is still confusing, and the official websites to sign up are often terrible, overloaded, broken, or confusing. Volunteer-run digital resources are filling in the gaps.

Across the country, people are turning to volunteer run and DIY resources in order to find appointments for the COVID-19 vaccine. There are now hundreds of websites, Twitter accounts, Facebook groups, Slack channels, and bots dedicated to helping people sign up to get the vax, most of which are focused on a specific state or geographic area.
