Compose Craft is an open-source visual diagramming and management platform that transforms raw Docker Compose configuration files into an interactive canvas of interconnected service nodes. Developers can drag and drop container services to map complex microservice architectures, automatically wiring port mappings, internal bridge networks, volume mounts, and dependency relationships. The real-time synchronization engine reflects every node repositioning, environment variable adjustment, and resource constraint directly into standard docker-compose syntax alongside a live editable code preview pane. Teams can import existing configuration files to diagnose routing conflicts, auto-format tangled service trees, and generate clean architectural documentation for operational handoffs. Engineers can generate shareable read-only public links to demonstrate infrastructure topologies to teammates and external reviewers without forcing them to register accounts. The built-in playground lets administrators experiment with container restart policies, healthcheck definitions, build contexts, and secret keys before deploying to production hosts. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
