JigSpec™Open-source AI pipelines as simple YAML

Build, record, and assemble fleets of AI workflows to automate the work you hate (or love) doing.

Get Started

Read the Spec

Simple things are simple

A one-step pipeline is 5 lines of YAML. No boilerplate, no classes, no setup code.

Composable fleets

Pipelines are steps inside other pipelines. Build small automations, assemble them into large systems.

Provider-agnostic

Swap Claude for GPT for Llama without changing your pipeline. One spec, any model.

Built for frontier models

Designed and tested with Anthropic Claude 4.x and OpenAI GPT-5 Codex models. These handle multi-step agent workflows reliably — results with smaller or older models are unpredictable.

Runs locally

Your pipelines execute on your own machine or infrastructure. No data leaves your network unless you choose a hosted model provider.
