Plane

What is Plane?

Plane is an open-source project management platform designed as a unified workspace for planning and execution. The tool combines three core features: Projects for tracking work and progress, Wiki for centralizing knowledge and documentation, and Plane AI for converting ideas into structured tasks and actionable items. The platform serves teams and AI agents who need to coordinate project work, maintain shared knowledge bases, and streamline workflow processes. Plane is particularly suited for organizations seeking alternatives to proprietary project management tools, with flexibility in deployment options including cloud hosting, self-hosted instances, and air-gapped environments for security-sensitive deployments. Key differentiators include its open-source nature, which allows teams to inspect, modify, and self-host the codebase, and its integrated AI capabilities that assist in transforming unstructured ideas into organized work. The combination of project tracking and wiki functionality in a single workspace reduces tool fragmentation, while the multi-deployment model provides options for teams with varying infrastructure and privacy requirements. Plane is free to use as open-source software, making it accessible to teams of any size without subscription costs.
