Launching ToolGrid (Early Access)

A local-first Rust + Freya toolbox for JSON, JWT, Base64, and more—built to keep sensitive data off the internet.

Tooling should speed you up—not ask you to paste production payloads into a dozen random websites.

ToolGrid is my answer: a native, offline-by-default developer toolbox built with Rust + Freya, designed to be fast, private, and frictionless.

One toolbox. Zero tab-hopping. Totally local.


Why I built it

Modern desktop apps are often built with Electron and web technologies. That’s not inherently bad—Electron is productive, cross-platform, and it ships.

But for developer utilities, the trade-off can feel brutal: you open a tiny tool and end up paying for a whole browser stack. Fans spin up, RAM usage creeps, and “quick” becomes heavy.

I was fed up with that.

So I built ToolGrid to be native-first with Rust + Freya—optimized for:

Every engineer has the same loop:

Most of the time, the quickest option is a browser tab. And that’s exactly the problem: browser utilities are convenient, but they’re also noisy, slow, and often unsafe for sensitive data.

ToolGrid keeps your payloads where they belong: on your machine.

What’s inside (today)

ToolGrid focuses on the “daily drivers”:

I’m keeping the core promise simple: open → search → run the tool → copy the result.

ToolGrid JSON Formatter
JSON Formatter
Readable payloads, instantly.
ToolGrid JWT Decoder
JWT Decoder
Inspect claims locally.
ToolGrid JSON to Data Structures
JSON → Data
Generate types/structs fast.

What “Early Access” means

ToolGrid is shipping in Early Access while I harden the experience:

If you try it and something feels off, that feedback is gold.

Technical Deep Dive: Packaging Rust GUI Apps

Ever wonder how I actually bundle a sophisticated Rust GUI like ToolGrid for Windows and Linux? It isn’t as simple as cargo build.

If you want to know the “under the hood” details of my packaging journey—from WiX installer nightmares to Flatpak manifests—head over here.


What’s next

I’m building toward a toolbox that’s:

If your team needs custom internal utilities or a privacy-first workflow, I also do services.
