Only if you are willing to fuck with it every week or two to keep it alive. They changed their free tier recently and they now turn off your project if it’s not “active”. (They don’t delete it, but your have to log in and turn it back on.)
I'm not an expert but I believe it boils down to something connecting to the DB within a week, which seems do-able once things are running and maybe a tiny hassle during initial dev if it's a weekend hobby project.
