Plane

About Plane

Plane is the work infrastructure for humans and AI agent era: one work graph that humans and AI agents operate as peers, structured enough for machines to read and reason over, humane enough for people to live in, and running wherever the work must live. It unifies projects, knowledge, and service so context no longer scatters across tools that split humans and constrain agents. Agents operate the same graph through a REST API and an official MCP server, with their own identity, permissions, and audit trail, so every action is attributable and on the record. Intelligence runs where the work lives: bring your own models and keep AI inside your perimeter. And it never coerces deployment: cloud, self-hosted, or fully air-gapped. Plane's Commercial editions run at full parity, and when you self-host, your data stays in your own infrastructure. Project management, run as infrastructure you control. Plane is trusted by 50,000+ teams in 63 countries, including teams in defense, aerospace, and finance. More than 10,000 companies have switched from tools like Jira, Linear, and ClickUp. It is certified to ISO 27001:2022 and SOC 2, and compliant with HIPAA and GDPR. Get started: plane.so
