Web & DevOps Tools

Web & DevOps tools bundle the small, repeatable utilities you reach for while building, configuring and deploying sites and services. Generate a full nginx server block or an Apache .htaccess with the Nginx Config Generator and .htaccess Generator, spin up SEO files with the robots.txt Generator and XML Sitemap Generator, and scaffold repos with the .gitignore Generator. The Chmod Calculator converts Unix permissions between octal and symbolic rwx, the HTTP Status & MIME Types reference makes status codes and content types searchable, the Semver Calculator parses, compares and range-checks semantic versions, and the Open Graph Generator builds social meta tags with a live card preview. Built for developers and DevOps engineers, every tool runs in your browser, so the domains, paths and values you enter are processed on your device and nothing is uploaded.

Frequently asked questions

What can I do with these Web & DevOps tools?

You can generate an nginx server block or an Apache .htaccess, build a robots.txt and an XML sitemap, assemble a .gitignore, convert chmod permissions between octal and symbolic rwx, look up HTTP status codes and MIME types, work through semver ranges, and create Open Graph and Twitter meta tags — the everyday tasks that come up while building, configuring and deploying web projects.

Which server config formats do these tools generate?

The Nginx Config Generator builds a complete server block for static sites or reverse proxies with optional SSL, gzip and caching, while the .htaccess Generator produces Apache rules for HTTPS and www redirects, 301s, compression, caching and security headers. Both update live and let you copy or download the file.

Can I create robots.txt and sitemap.xml files here?

Yes. The robots.txt Generator lets you build user-agent groups with allow/disallow paths, crawl-delay and sitemap lines, and the XML Sitemap Generator turns a list of URLs into a standards-compliant sitemap.xml with optional lastmod, changefreq and priority — both ready to copy or download.

Are these Web & DevOps tools safe to use?

Yes. Each tool runs in your browser, so configs, permissions, ignore templates, URLs and meta values are processed on your device. Nothing is uploaded, which means internal domains, paths and IP addresses stay with you.

Do the Web & DevOps tools work offline?

Once the page has loaded, the tools run on the client, so the config generators, chmod calculator, HTTP reference, semver calculator and Open Graph Generator keep working without a live connection. Your inputs are computed locally rather than sent to a backend.

Who are these Web & DevOps tools built for?

They are built for developers, DevOps and platform engineers, and site owners wiring up web infrastructure — anyone who needs to generate a server config, produce SEO files, set file permissions, reason about versions or prepare pages for sharing without switching to a terminal or a half-remembered reference.
