🛡️ Why Support DevArmory?
Every software engineer needs quick utilities daily: formatting an unreadable JSON payload, diffing two code snippets, converting a cURL command into Python or Fetch, or inspecting an expired JWT.
The hidden problem: Most free online formatters quietly transmit whatever you paste back to unknown remote servers. If you are handling customer JSON containing PII, proprietary SQL queries, or internal API bearer tokens, you're unwittingly leaking sensitive data.
I built DevArmory (https://devarmory.org) around a single foundational rule: your data never leaves your computer.
