Set a spending cap before building with Replit Agent

A student built a first MVP with Replit Agent but was surprised by how much repeated debugging and rework added to the bill.

What they did
They used Replit Agent to make a simple first version of an app, with a basic interface connected to Supabase. The agent handled open-ended building and bug-fixing over several rounds, while support later suggested restarting sessions when it began repeating itself.
How it went
After about two days, the account had reached $20 for Replit Core and roughly $65 for agent usage. The app was still less than halfway done, and the biggest issue was unexpected spend from looping and redo work rather than visible progress.
Tips
Set a firm budget before the first prompt. If the agent starts cycling, switch to a cheaper mode and begin a fresh chat before it keeps burning credits.

Try it yourself with Replit Agent

Help me build a first version of [project]. Start with the simplest useful approach and estimate the likely agent cost before you begin. Break the work into small steps and show me the plan first. After each step, stop and ask for my approval before moving on. If you run into repeated failures or start going in circles, pause and tell me so I can decide whether to restart. Keep going only while I stay under [budget] and stop once the main feature works.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
