# Tools & Utilities

Source: https://www.potatoannotator.com/docs/tools/overview

Potato ships several command-line tools alongside the server. [Preview CLI](/docs/tools/preview-cli) renders a config to static HTML without starting a server, which is the fastest way to check that a scheme looks the way you intended. [Migration CLI](/docs/tools/migration-cli) upgrades configs between Potato versions.

[User Simulator](/docs/tools/simulator) generates synthetic annotators. It is useful for load testing, and for checking that an assignment strategy distributes work the way you expect before real people are waiting on it.

[Debugging Guide](/docs/tools/debugging-guide) covers what to do when a config loads but the task does not behave.
