Built NetDrill: free CCNA and CCNP network labs in your browser. No install, no account. Configure routers and switches from the CLI, and each lab is graded on what the network does, not on the keys you typed

Your Dev Tools Are Leaking Data. Here’s Why I Built Mine to Run Entirely in the Browser.

Most online “developer tools” aren’t tools.

They’re upload portals.
**
Paste your JWT.**
Drop your logs.
Submit your JSON.

Now your sensitive data just passed through someone else’s server.

That’s unnecessary.

The Constraint

I built SureWhyNot with one hard rule:

No backend.
No accounts.
No uploads.
No server-side processing.

Everything runs fully in the browser.

JSON formatting.
JWT decoding.
Hash generation (Web Crypto).
CSP analysis.

If your browser can compute it, it should compute it.

Why It Matters

Removing the server removes:

Data transmission risk

Storage liability

Logging ambiguity

Extra attack surface

The architecture is intentionally boring:

Static deployment.
Zero API endpoints.
Stateless model.

Project:
https://surewhynot.app

Not everything needs a backend. Sometimes the right architecture is subtraction.
