Huly

Huly is an open-source, all-in-one project management and team collaboration platform (an alternative to Linear, Jira, Slack, and Notion) built around modules like Tracker and Documents. Programmatic access is delivered primarily as a Node.js SDK (@hcengineering/api-client) that connects to the platform transactor over WebSocket or REST, rather than a broad public HTTP API. Huly is available as free, self-hostable open source (github.com/hcengineering) and as managed Huly Cloud.

Huly publishes 4 APIs on the APIs.io network, including Platform SDK, Cloud, Tracker, and 1 more. Tagged areas include Project Management, Collaboration, Open Source, Productivity, and SDK.

Huly’s developer surface includes documentation and 7 more developer resources.

  description: The @hcengineering/api-client Node.js package provides typed programmatic access to the Huly Platform. It exposes
    a WebSocket client (connect) holding a persistent transactor connection and a REST client (connectRest), both authenticated
    by email/password or token, with document operations such as findOne, findAll, createDoc, updateDoc, and removeDoc. There
    is no broadly documented public HTTP REST API with stable URL paths; access is intended through this SDK.
