Build, optimize, and security-harden Dockerfiles, .dockerignore files, and docker-compose.yml configurations for Next.js, Node, Python, Go, and Model Context Protocol (MCP) AI servers with 100% browser-local privacy.
All Dockerfiles and compose configs compile locally in browser memory. Zero server uploads.

Choose your target framework (Next.js App Router, Python FastAPI, Go Alpine, Express, or MCP AI Server) and select runtime version and base image OS flavor.
Toggle Multi-Stage builds to reduce image size, enable non-root `USER` hardening to prevent container breakouts, and append native `HEALTHCHECK` directives.
Inspect generated `Dockerfile`, `.dockerignore`, and `docker-compose.yml` tabs, copy formatted markup, or download configuration files directly.
Zero network transmission. Your application settings, port numbers, environment keys, and build scripts stay 100% in local browser memory.
Separates dependency installation, build compilation, and lightweight runtime stages to produce minimal container image sizes.
Automatically injects non-root `USER node` / `USER appuser` directives and directory permissions (`chown`) to prevent container breakout exploits.
One-click starter configurations for Next.js App Router (Standalone output), Python FastAPI (Uvicorn), Node.js Express, Go Alpine, and MCP Agent Servers.
Exports tailored `.dockerignore` files and multi-service `docker-compose.yml` configurations with environment file mapping and health checks.
Includes native Docker `HEALTHCHECK` instructions and orders `COPY package.json` layers first to leverage Docker layer caching efficiently.
Containerizing production web applications and AI agent microservices requires strict separation of build dependencies from runtime environments. Single-stage Dockerfiles frequently embed build toolchains, unneeded compiler utilities, and devDependencies, swelling final image sizes beyond 1.5 GB and expanding the container attack surface.
Furthermore, running Docker containers as `root` inside cloud Kubernetes clusters or AWS ECS tasks violates the principle of least privilege. Injected non-root users (`USER node` / `USER appuser`) safeguard application workloads by restricting container file system access if an arbitrary code execution or dependency vulnerability occurs.
HiMat's Dockerfile & Docker Compose Generator compiles container blueprints completely inside your local browser instance. Neither your domain names, port bindings, environment keys, nor code directory structures are transmitted to remote servers.
It is a browser-local developer utility that generates optimized multi-stage Dockerfiles, `.dockerignore` files, and `docker-compose.yml` configs tailored for web frameworks and AI MCP servers.
No. The HiMat Dockerfile Generator operates 100% locally in your web browser. Neither your container parameters, environment variables, nor generated Dockerfiles leave your local machine.
Multi-stage builds discard build tools and devDependencies, reducing image size from gigabytes to megabytes. Non-root users (`USER node` / `USER appuser`) prevent privilege escalation attacks if a container dependency is compromised.
For Next.js App Router, enable `output: 'standalone'` in your `next.config.ts`. The generated multi-stage Dockerfile copies only the minimal standalone server bundle for ultra-fast production deployment.
