Polar is a developer-focused tool for creating and managing local Bitcoin and Lightning Network test environments on a desktop computer. With a drag-and-drop interface, developers can spin up multi-node Lightning networks locally using Docker containers — connecting LND, Core Lightning, and Eclair nodes. Polar is widely used in Lightning application development for testing payment flows, channel management, and BOLT compliance before deploying to mainnet.
