About

Julep defines agents as durable dataflows with a Python @flow decorator, and the README says flows can crash and resume, retry safely and explain each step. Tools must be registered, and the model is limited to the tools it was explicitly allowed to call. A developer CLI lists, runs, tests and deploys agents, and its trace view links to Langfuse. The self-hosted control plane includes an encrypted secrets vault, and the Temporal layer is optional.

Done for you

Rather not set it up yourself?

Chalk Labs scopes, builds and runs agents for your team: the task audit, the eval harness, the integrations and the weekly ops report. Fixed scope, priced before we start.
