The two differences that change the math
Build with the AI you already pay for
If you already pay for ChatGPT (Codex) or Claude Max, you connect it to Infusion and build without counting credits. In Replit, you buy credits.
A fixed price to keep the app live
In Infusion, the app's machine has a fixed price. In Replit, hosting and database are paid from the same credits used for building, then billed by usage.
Questions about Infusion and Replit
What people comparing the two ask most.
Yes. Both build full apps from a text description. The differences are in how you pay: with your AI subscription or with credits, and with a fixed or usage-based price to keep the app live.
By effort, according to Replit: the longer the agent works, the more credits it uses. More complex requests cost more.
According to Replit's pricing page, you buy a credit pack or start paying for extra usage, up to the spending limit you set. When the limit is reached, Replit suspends the usage-billed services.
No. Credits already come with the plan. If you already pay for ChatGPT (Codex) or Claude Max, you can connect it and build without depending on credits.
Your app stays live, because credits and infrastructure are billed separately. Credits are for building, and the app's machine has its own fixed price. When credits run out, you can connect your AI subscription and keep building the app the same way.
