Tools Generators

Files you would otherwise write from memory.

Produce the config files, templates, and values you would otherwise write from memory, deterministically and in your browser.

Generators tools

generators Local UUID Generator Generate random UUID v4 values locally without sending them anywhere. generators Local Random Token Generator Generate cryptographically secure random tokens locally in your browser. site.conf Local Nginx Config Generator Generate an nginx server block for a reverse proxy or a static site, including the directives that belong in the http block. name.service Local systemd Service Generator Write a complete systemd .service file from a few fields, including the directives that only work in pairs. .env Local .env Template Generator Generate a starter .env for the services you use, with conventional names and working local defaults. .gitignore Local .gitignore Generator Build a .gitignore from maintained fragments for your languages, frameworks, editors, and tooling. .env.example Local .env.example Sanitizer Turn a real .env into the .env.example you can commit, with every value emptied unless a stated rule keeps it. compose.yaml Local Docker Run to Compose Converter Turn a docker run command into a Compose service, with every flag it cannot translate reported. robots.txt Local robots.txt Generator Generate a deterministic robots.txt starter file from readable local rules. generators Local QR Code Generator Generate QR codes for text, links, contact details, Wi-Fi, and messages in your browser. code-snippet Local Code Snippet Image Generator Turn source code into a polished JPG or standalone HTML card locally. generators Local Color Harmony Generator Pick a base color and generate complementary, analogous, triadic, split-complementary, tetradic, square, and monochromatic palettes locally. generators Local ULID Generator & Inspector Generate cryptographically random ULIDs and inspect their timestamp and random components locally.

HOW THESE DIFFER

A generator takes choices, not a document.

The rest of the toolbox transforms something you already have: paste a URL, a token, or a JSON document and get it back explained, converted, or compared. A generator starts from nothing. You pick what applies, and the output is a file to save or a value to paste.

That difference is why these are held to a stricter rule. A generator that produced slightly different output each time, or that invented a plausible-looking directive, would be worse than no generator at all, because its output goes straight into a repository or onto a server. So the fragments are fixed and dated, the same selection always produces the same file, and anything a generator cannot express is reported rather than guessed at. The one deliberate exception is a value that has to be unpredictable to be worth anything: a UUID, a token, a secret.
