Replit Core is the membership to unlock the full Replit experience.
If you want to make your Repls more powerful, you can use the Boost Power Up to increase the number of vCPUs and how much RAM your Repl has.
With a free Replit account, personal Repls are public by default.
With SSH, you can access your Repl's shell remotely. SSH enables workflows like easy file transfer or using your favorite local IDE to edit your code on Replit.
