When should I use a headless agent vs. one with a UI?

Use headless agents for batch processing, scheduled tasks, and workflows where human interaction during execution adds no value. Use agents with a UI when users need to ask ad-hoc questions, review and approve agent actions in real time, or interact conversationally. Many deployments combine both: a headless agent handles routine processing and a UI-based agent handles exceptions and questions.

Headless Agent

An AI agent that operates without a user-facing interface—running entirely in the background via APIs, webhooks, or scheduled triggers. Headless agents process data, execute workflows, and take actions without any chat window, dashboard, or UI. They're ideal for automation tasks where no human interaction is needed during execution: overnight data processing, background lead enrichment, automated report generation, or continuous monitoring.

Example

A headless finance agent runs every night at midnight: it pulls the day's transactions from the bank feed, categorizes each one against the chart of accounts, matches invoices to payments, flags discrepancies, and emails a summary report to the controller. No UI, no chat—pure background automation.
