Every developer has done it — copy-pasted a JWT, a private key, or a JSON blob with sensitive data into some random website and held their breath. Wondering if it was being logged, tracked, or worse.
I built KRUMB.DEV because I wanted tools that didn't make me feel dirty after using them.
What Is It?
46 developer tools, all in one place. No signup. No uploads. No tracking. Open source.
The terminal-inspired interface isn't just aesthetic — it's a constraint. Every tool fits in a single column, zero sidebar, zero popups. Just you and the tool.
