Frequently asked questions
Is Dockerfile really free?
Yes — Dockerfile is 100% free with no limits, no watermarks and no registration. You can use it as often as you like, on as many files or inputs as you need.
Is my data safe when I use Dockerfile?
Absolutely. Dockerfile runs entirely in your browser using JavaScript — your input is processed on your own device and is never uploaded to any server.
Does Dockerfile work on mobile devices?
Yes. Dockerfile works in any modern browser on desktop, tablet and mobile (Chrome, Firefox, Safari, Edge) — there is no app to install.
Do these tools touch my servers?
No. OpsForge tools are pure calculators and generators that run in your browser — they never connect to your infrastructure. You copy the result and apply it yourself.
Is the chmod calculator accurate for all systems?
Yes — octal permission notation is a POSIX standard, so the results apply identically on Linux, macOS and BSD.
Will more DevOps tools be added?
Yes — Dockerfile, docker-compose, nginx and CI config generators are on the roadmap. Everything will stay free and client-side.
