Config File Generator
3 config generators in one tool: Dockerfile builder with presets for Node/Python/Go/Static/Generic, a .gitignore composer for common stacks, and an .htaccess/Nginx rules builder — all generated instantly and copyable.
- Pick a mode: Dockerfile, .gitignore, or .htaccess / Nginx.
- For Dockerfile, choose a stack preset (Node, Python, Go, Static/Nginx, Generic) and fill in a few relevant fields like entry file and port.
- For .gitignore, check off the stacks and tools you use (Node, Python, macOS, VS Code, etc.) — selected presets are merged and deduplicated automatically.
- For .htaccess / Nginx, toggle the format, check the recipes you need (force HTTPS, gzip, cache headers, etc.), then copy the generated config into your project.
All processing happens entirely in your browser. Your data never leaves your device.
Key Features
- Dockerfile generator with 5 stack presets: Node, Python, Go, Static/Nginx, and Generic Linux
- Node preset supports npm, yarn, or pnpm with the correct install command for each
- Multi-stage Dockerfile output for the Go and Static/Nginx presets
- .gitignore composer covering Node, Python, Java, macOS, Windows, VS Code, IntelliJ, env files, and build output
- Automatic deduplication when multiple selected .gitignore presets share the same ignore pattern
- Apache (.htaccess) and Nginx server-block output from the same set of recipe checkboxes
- Recipes for forcing HTTPS, www/non-www redirects, custom 404 pages, gzip, and static asset caching
- One-click copy for every generated file, ready to drop straight into your project
About Config File Generator
Config File Generator bundles three everyday DevOps chores into one tool: writing a Dockerfile, assembling a .gitignore, and composing server rewrite/cache rules for Apache or Nginx. These are files nearly every project needs, but their syntax is easy to get subtly wrong — a missing EXPOSE line, an outdated .gitignore pattern, or an Apache RewriteRule that doesn't quite match the intended behavior.
The Dockerfile mode uses a preset-driven template system: pick your stack (Node, Python, Go, a static site served by Nginx, or a generic Linux base image) and the tool fills in a sensible base image, WORKDIR, dependency install step, EXPOSE, and CMD — you only need to tweak a handful of stack-specific fields like your entry file or port. The .gitignore mode maps each common stack or tool (Node, Python, Java, macOS, Windows, VS Code, IntelliJ, env files, build output) to its well-known canonical ignore patterns, merging your selections and removing duplicate lines. The .htaccess / Nginx mode composes common production recipes — forcing HTTPS, redirecting to/from www, custom 404 pages, disabling directory listing, gzip compression, and cache headers for static assets — into the correct directive syntax for whichever server you toggle to.
Everything is generated instantly in your browser from simple template logic; there's no server round-trip and no config is ever transmitted anywhere.
Frequently Asked Questions
The presets produce a working starting point for a typical project layout, but you should double-check paths (like your entry file name) and add any extra build steps your specific app needs — it's a solid template, not a guarantee for every edge case.
It covers the most common, well-known patterns for each stack (the ones you'd find in GitHub's official gitignore templates), not an exhaustive list. You can always append project-specific lines after copying the output.
Apache uses .htaccess directives (RewriteEngine, RewriteRule, mod_deflate, mod_expires) that live in a file inside your web root. Nginx uses a server block snippet that goes inside your nginx.conf or a site config file — the same recipes are expressed in each server's own syntax.
No. All templates are generated with local JavaScript string building — nothing about your project is uploaded or logged.
Yes — every checkbox (force HTTPS, www redirect, gzip, caching, etc.) is independent, so you can enable as many as you need and they'll all be composed into a single output file.
