Micro-SaaS built and deployed
The author used Replit Agent to build and deploy Calendar Autobot, an app that turns forwarded emails and images into Google Calendar events.
A production micro-SaaS went live in about 3 hours, versus an estimated 3 to 4 weeks solo.
Overview
How it was set up
Replit paid plan with Agent. Stack: Python, Flask, PostgreSQL, OpenAI, Google OAuth, Mailgun. Starter prompt generated in Google AI Studio. Early logging helped the agent debug.
Worth knowing
The agent bloated code and looped on Google OAuth and Mailgun. The author reviewed code and wrote specific prompts with docs links to steer it.
A prompt to start from
Using Python Flask, create a backend API that takes [email or document text], extracts every event (name, description, start and end date and time, location) as a JSON list, resolves relative dates from [CURRENT DATE], and creates matching Google Calendar events.
