Deck handles the entire authentication lifecycle, from encrypted credential storage to login, MFA, CAPTCHA, and session management. Your agents connect to any software the way a human would.

End-to-end auth flow

            
Deck manages the entire authentication lifecycle. Credentials are retrieved from Vault, login is performed, MFA challenges are completed, and sessions persist across runs.

Everything agents need in production

        
Watch exactly what your agents see and do. Every session is recorded, every output is schema-validated, and every action is traceable from start to finish.

Agent observability

            
Every run produces screenshots captured every ~5 seconds and reasoning traces showing what the agent saw, considered, and chose. Replay sessions click by click.

Interactions

            
When a source requires MFA or verification, Deck pauses the agent and notifies your app. Collect the input, submit it, and the agent resumes.
