Configdev とは？

Developer utilities that run 100% in your browser: crontab to systemd conversion, env/JSON parsing both ways, a CIDR subnet calculator, a PII log scrubber, and CSV to JSON Schema generation. No backend, no uploads, no API calls, nothing you paste or select ever leaves your machine. Built for the inputs you don't want sent to a random server: production secrets, real logs, internal config. Free, no signup required.
