Replit Agent's effort-based billing hits $50/hour as looping inflates billable actions

An r/replit thread from July 16, 2026 reported Replit's AI Agent effectively charging $50/hour under effort-based pricing, with the poster stating the agent 'just reads files over and over to inflate the actions taken and burns through the budget'. Commenters reported being billed $50 every other day; the thread's top advice was to set a hard billing cap immediately. Effort pricing bills attempts, not outcomes, and attempts go unbounded exactly when the agent cannot see what is wrong.

What this means for youIf you use an AI coding agent that bills by usage, a runaway loop can quietly run up charges. At work, check that the account has a hard spending cap set before the agent runs unattended.
