I love Gridsome, and it had tons of potential, but it's effectively a dead project. The maintainers haven't cut a new release since November 2020.[0] There's barely been any feature work since 2019.[1] Their Github repos have tons of PRs that have not been reviewed. There are serious site-killing bugs that have not been fixed for over a year.[2]
I really wanted this project to succeed. I asked to sponsor the project and volunteered working on their documentation for a few months, but it didn't seem to yield any new dev work.
The maintainers are extremely talented, and this is not a knock against them, but I just caution anyone against marrying themselves to a framework that's unlikely to have any ongoing maintenance.
