Why Self-Host?
The official demo at it-tools.tech is publicly available — but self-hosting makes sense for a few reasons:
Privacy — Even though everything runs client-side, keeping it internal is the right call when handling sensitive values like API tokens, private keys, or JWTs.
Always available — No dependency on external uptime or internet access.
It’s 20 MB. There’s genuinely no reason not to.
