Build and ship a small SaaS with Replit fast

A developer used Replit Agent to take a calendar tool from idea to production in about three hours.

What they did
Will Cheung, a technical hobbyist, put together Calendar Autobot on paid Replit. It accepts emails and images, then creates Google Calendar events, with Python, Flask, PostgreSQL, OpenAI, Google OAuth, and Mailgun in the stack. He started from a prompt he drafted in Google AI Studio, and that first pass got the app most of the way there. Replit Agent then helped chase bugs from logs, clean up the code, manage migrations, and deploy the app, while he reviewed the work and took over when it stalled.
How it went
He says he got it live in around three hours. He also estimates the same build would have taken him 3–4 weeks on his own. The email feature kept going after that, but the agent got stuck repeatedly on Google OAuth and Mailgun until he supplied official documentation.
Tips
Give the agent logs early, since they make debugging much easier. Turn off auto-publish when you want to inspect bigger changes before they go live, and use a separate production database because Replit’s production logging is limited.

Work in small steps, show your progress after each major stage, and use logs to find and fix issues. Set up the database and any migrations, then prepare a deployment plan. Before you do anything irreversible, such as sending something, deleting something, submitting a form, connecting an account, or charging money, stop and ask for my approval. If you run into an integration problem, tell me exactly what documentation, credentials, or settings you need from me.
