What are some Replit project examples?

Replit suits small apps you want public fast: a Flask landing page that stores emails in Replit's built-in database, an Express API that reshapes third-party data, or a Discord bot. From the idea library, try a daily standup bot, an invoice reminder bot, or an AI code reviewer. Agent helps write it, and Deploy puts it online.
