Hey everyone, maker here. I built ConfigDev because I kept needing to convert env files, check CIDR ranges, or scrub PII from logs, and most free tools online run that processing through a server. For one-off harmless data that's fine, but I didn't want to keep pasting real secrets and config into something I had no visibility into. So everything here runs entirely client-side, you can verify it yourself by checking the network tab or just going offline. Happy to answer questions about the tools or the "no backend at all" approach, and genuinely interested in feedback on where it could be better.
