Portainer is a lightweight, open-source web-based UI that simplifies management of Docker, Kubernetes, Swarm, Podman, and ACI container environments for developers and operations teams.

---

🚀 Overview

Portainer is a universal container management platform offering a simple GUI and API to deploy, manage, and scale containerized applications across Docker, Kubernetes, Swarm, Podman, and edge environments. It eliminates the need for command-line expertise or complex tools, providing centralized visibility and control.

What problem does this project solve? It addresses the complexity and specialist overhead in managing containers at scale, especially in multi-cluster, hybrid, or air-gapped setups, making operations accessible to non-experts.

• Who is it built for? Developers, DevOps/IT teams, enterprises, and OT teams in industrial/IoT settings.
• Why did you build it? To democratize container management with an intuitive interface, starting as an open-source solution to fill the gap in easy Docker UIs and evolving for enterprise needs.

Keep it human and honest: No more wrestling with CLI—Portainer brings sanity to container chaos.
