Free tools

Use a tool right now.

Everything here runs free. Some work fully in your browser; the heavier ones run on my servers — no install.

Services

Automation, built for your shop.

When a free tool isn't enough, I build the custom thing through gravalley, my company. First build is free — you pay once it earns its keep.

No upfront cost. I build it, you try it, you pay only when it works for you.
Pricing

Free where it can be. Fair where it can't.

The tools stay free. For custom work, you only pay once it's proven on your own data.

Selected work

Shipped for real factories.

Label and barcode automation running in production for global apparel brands.

About me

Bridging the gap between apparel and automation.

I'm Md. Jahid Hasan — an Apparel Automation Specialist with a print and label production background. I build the tools factories actually use day to day: ZPL label generation, barcode and RFID workflows, and PDF layout automation.

I don't just talk about automation — I ship it. From print-ready label grids and Excel-driven barcode generators to chatbots and custom dashboards, I turn tedious manual work into one-click tools.

My approach is simple: I build it, prove it on your data, then you pay. The free tools on this page are the front door; gravalley is the studio behind them.

About

A company, one person behind it.

I design and build the tools on this page myself. The studio I run them under is gravalley, my company for apparel and retail automation: ZPL labels, barcode generation, and the custom software factories actually use day to day.

Brands like Renner and Kenneth Cole already run on this work. The free tools are the front door; gravalley is what's behind it.

How it works

A proven process for real results.

01

Discovery

We start with your workflow — labels, data, the manual steps eating your team's time. I learn exactly what needs automating.

→
02

Build

I design the tool around your real files — ZPL, Excel, barcodes — and build a first working version, free.

→
03

Deploy

It runs on your own data, in your shop. We test on real POs until the output is print-ready and reliable.

→
04

Support

Once it earns its keep, I keep it running — fixes, updates, and new tools as you grow.

How free works

Try it once. No account.

Run any tool a first time with nothing to sign up for. Come back, and a free account keeps you going — and saves your files between runs.

01

Pick a tool, run it

Upload your file and get the result. No account, no email — your first run is on me.

02

Come back? Sign in free
