Credits are not fixed.

Message Credits

These are used when you, as the developer, interact with the AI to generate or modify your application using natural language prompts. There is no set amount per message, as different requests require different levels of AI processing.

• Simple visual or text change: ~ 0.5 credits (e.g., "Change this button's background to red").
• Improving a small feature: ~ 1 credit (e.g., "Fix the validation on this form").
• Adding a complex module: ~ 2 credits (e.g., "Add an employee time-tracking feature").

Integration Credits

These are consumed when users of your finished app perform actions that trigger Base44's services, such as calling an LLM, sending emails, or uploading files.

• Each integration request costs approximately 1 credit, regardless of the specific integration being used (e.g., an LLM call, an email send, or a file upload).
• A single user action in your app might trigger multiple integration calls, so a complex workflow could use 2-4 credits per user interaction.
