Web Config Generator is part of DevStudio — a free, in-browser collection of developer utilities that work without sign-up, installation, or any backend service. Emit robots.txt, sitemap.xml, .htaccess, NGINX, Apache vhost, PWA manifest, OG/Twitter meta, Schema.org JSON-LD, favicons, all running entirely on your device. Because the page never uploads what you paste, you can run sensitive payloads, configuration files, secrets, or production data through it with confidence: nothing leaves your browser tab. Use Web Config Generator for ad-hoc debugging, code review, log triage, release prep, learning a new format, or as a quick scratchpad while you build. If you use this tool a lot, pair it with UUID / ULID, Identifier Toolkit, Password Generator, and the rest of the DevStudio toolkit for related developer workflows.
