Frequently asked questions about Backprompter
Do you store my prompts and agent outputs?
No. Backprompter has zero data retention—your prompts and outputs are never stored by model providers.
How do I deploy my agent?
Three options: publish a hosted chat UI (no code), build a custom interface with the frontend SDK, or call agents from your backend server via the API.
Can I use my own backend?
Yes. Use the backend SDK with your own API key and handle user authentication however you prefer—Backprompter never sees user credentials.
