About this tool

IconVault's Compose Generator builds a valid docker-compose.yml without you writing a line of YAML. Add services with a visual form: image, ports, volumes, environment variables, depends_on, restart policy and networks. One-click presets for Nginx, Node.js, Postgres, Redis, MySQL and MongoDB fill in sensible defaults you can tweak.

The YAML output updates live as you type, so you always see exactly what your stack will look like, then copy it or download the file with one click. Everything runs 100% client side in your browser: no server, no account, no uploads. Visitors get 5 free generations with no signup; IconVault Pro ($12/year) unlocks unlimited use of every developer tool.
