Developer docs

Developer preview. The packages aren't on npm yet, and access is by invitation while the platform is in preview. Everything here is taken from the packages' own READMEs and the example app's source, so it describes what the code does today.

There are two packages:

• @jwtson/sdk runs on your server. It defines agents and workflows, starts runs, follows them as they stream, answers what they ask and hears about them through webhooks. It has no dependencies and is tested on Node 24.
• @jwtson/react runs in your users' pages. Your server signs each person in and hands the page a client session, so the API key never reaches the browser. It gives hooks for runs and chats, and unstyled components for questions, approvals, progress and files.

Where to start

• Product guide: learn the concepts, configure your first agent in the console, and build a workflow.
• Quickstart: an agent and its answer, streamed, in a few lines.
• Embedding in your product: client sessions, groups and roles for a signed-in user's page.
• Full example app: a complete React app and its server, line for line.
• When Jwtson calls you: webhooks, being called as a tool and signed events.
