Welcome to the Stacksync Developer Platform
Build workflow connectors with the Stacksync CLI and CDK, and manage workspaces with the Stacksync API.
The Stacksync Developer Platform lets you extend Stacksync with your own code. With workflow connectors, you add actions for internal systems, proprietary applications or any API to Stacksync workflows. You build and test a connector on your machine, and Stacksync reviews, hosts and runs it once you deploy it.
👉 New here? Install the CLI, then build your first workflow connector.
Stacksync CLI
The command-line tool that creates a connector project, runs it in your workspace while you develop, and deploys it.
Stacksync CDK
The Python library you write a connector's modules with: their forms, dropdowns, actions, credentials, errors and context.
Stacksync API
The Stacksync API lets your own code manage the syncs, workflows, Genies and other resources of a workspace over HTTPS. The API Reference documents every operation, and is also published as an OpenAPI document.
For AI agents
Every page is also available as Markdown: add .md to its URL, for example /developers/stacksync-cdk/modules.md. /llms.txt lists every page. A connector project generated by the CLI includes AGENTS.md and a guide/ folder, so a coding assistant follows the same rules that Stacksync checks at deployment.
