Best Work & Workspace Management (2026)

AppFlowy is a privacy-first, open-source workspace that brings projects, wikis, and team collaboration together, widely regarded as the leading open-source alternative to Notion. It offers documents, databases with grid/board/calendar views, project tracking, and AI features, and can be self-hosted (AppFlowy Cloud) so teams keep full control of their data. Built largely in Rust and Dart (Flutter) for cross-platform native apps, it is AGPL-3.0 licensed and was founded in 2021.

Licensed under EPL-2.0 with a Docker-first self-host repo (huly-selfhost), it is built by Hardcore Engineering Inc. and is one of the fastest-growing open-source PM platforms.

Leantime is an open-source, goals-focused project management system designed for non-project managers and built with ADHD, autism, and dyslexia in mind.

The core is AGPL-3.0 and self-hostable via Docker or direct install; paid Cloud and Enterprise tiers add advanced features and support.
