**APIs profiled:** 4

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.
