About 85 dollars in roughly 2 days, the app under 50%
The author had Replit Agent build a first MVP. It is under 50% done. The bill was 20 dollars a month plus about 65 dollars of usage, about 85 dollars in roughly 2 days. He received a 20 dollar credit and is waiting on the usage amount of about 66 dollars.

What was done
On 23 June 2026 the author writes that Replit Agent built his first real project, a simple MVP with a UI, Supabase and a few rounds of iteration. The app is still under 50% done. Core costs 20 dollars a month. Agent usage on top was about 65 dollars. Together about 85 dollars, in roughly 2 days. Spending caps are off by default. He had to set a limit himself in the billing dashboard, and he did not know it existed until the bill arrived. The price also includes the agent's own retries when it loses the thread and redoes work. Support said completed usage is final under the terms. They told him to reset the session if the logic starts to drift. The first reply was a denial. After he pushed on the drift, he received a goodwill credit of 20 dollars. He has asked them to look at the full usage amount of about 66 dollars, and he is waiting.
How it went
A credit of 20 dollars has been given. About 66 dollars of usage is not decided. The app is under 50% done.
Worth knowing
The app is not named. About 65, about 85, roughly 2 days, under 50% and about 66 are his wording. The rest of the amount is not refunded in the post.
How to do it
- Set a spending cap before the first prompt, and set an alert under the cap as well.
- Split the build into one bounded step. If the agent repeats itself, reset the session.
- Read the bill. Do not let it continue while a dispute is waiting.
Try it with Replit
Build [feature] in [project] in one step. Stop if you repeat the same attempt. Do not spend more credit, and do not continue the session, until I say yes.
Replace text in brackets with your own.
Done when. The step has been read, and the session is stopped if it repeats itself.
Safety rule. No further credit use until you have said yes.
