Frequently asked questions

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.
