Something I do not see discussed enough in privacy circles: the tools developers use daily often send sensitive data to third parties.

Think about it:

• JSON formatters — you paste your API responses (which may contain user data) into random websites
• JWT decoders — you paste authentication tokens into online tools
• QR generators — whatever URLs or data you encode
• SSL checkers — reveals your infrastructure

All of these are trivially self-hostable. I run a full dev toolkit on a $5/mo VPS that handles all of this locally. Zero data ever leaves my server.

The privacy benefits:

• No analytics tracking what you paste
• No third-party logging of your API responses
• No risk of token/credential leaks through browser extensions or third-party JS
• Full control of logs and data retention

For developers who care about privacy (even just for professional/compliance reasons), self-hosting your dev tools is low-hanging fruit.

I wrote a free guide covering the full setup: Self-Hosting Guide for Developers

Anyone else self-hosting their dev tools for privacy reasons?
