What does the Compose builder generate?

It creates a Docker Compose YAML definition for configured services, images, ports, environment variables, volumes, and networks.

Can I define multiple services?

Yes. Add services such as an application, database, or cache and configure each service independently in the builder.

Is the generated YAML production-ready?

It is a useful starting point, but review image versions, secrets, health checks, resource limits, and persistence before production deployment.

About this tool

Build a valid docker-compose.yml visually — services, ports, volumes and env vars. Free online Docker Compose builder, no signup required. Docker Compose Builder runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

Docker Compose Builder is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.

From docker run to docker-compose.yml: Converting One-Off Commands into Versioned Files

Why a checked-in Compose file beats a one-liner in your shell history, the exact flag-to-key mapping the converter uses, and the gotchas worth knowing when you migrate.

A Sane Starting Point for docker-compose.yml

The Compose fields you actually need — services, ports, volumes, environment, depends_on and restart policies — without the YAML foot-guns.

.env Secret Safety Linter

Validate .env syntax and spot likely leaked credentials or placeholder secrets.

2D Fluid Dynamics & Particle Physics Sandbox

A physics playground with two engines sharing one canvas. The fluid mode runs a real Eulerian Navier-Stokes solver — semi-Lagrangian advection, explicit diffusion, Jacobi pressure projection and vorticity confinement — that you paint with dye and velocity using mouse or touch. The particle mode is a damped Verlet N-body engine with gravity wells, Coulomb attractors and repulsors, spring links, wall restitution and elastic circle collisions. Particle counts adapt to the device (100k target on WebGL2 desktop, 2k-5k on CPU fallback), and every configuration exports as runnable code: a Matter.js world, a PixiJS ticker setup, or a standalone vanilla Canvas engine.

Algorithm Arena & Data Structure Visualizer

Interactive arena for algorithms and data structures: eight sorting algorithms racing on one seeded input, six pathfinding algorithms walking generated mazes, and BST, AVL, Red-Black, B-tree, heap and trie operations replayed step by step with rotations highlighted. Every run shows the Big-O table and the phase-highlighted reference implementation in four languages, and compared values can be played as pitch (sonification) through the shared audio engine. Everything runs client-side; inputs never leave the browser.
