Independent software studio · Howrah, India

Tools forged
for the plant floor.

We build precision instruments for the people who build real things.

Devil's Workshop is an independent studio crafting professional engineering software — computed to code, shaped by real industrial work, and made by the engineers who actually use it.

The workshop

Most engineering software is written by people who have never stood at a pipe rack. Ours isn't.

01

Computed to code

Engines built faithfully from the source standards — ASME, ISA, TEMA, B36.10 — not curve-fit approximations. The maths is the product.

02

Output that ships

A number on a screen isn't the job. Our tools produce the datasheet — the deliverable you can hand to a checker and file.

03

Made by a user

Built by a practicing plant engineer, refined against actual project work. If it doesn't earn its place on the job, it doesn't ship.

Mr. Giga PLANTiEKalC uV

Seven calculators · ASME VIII · ISA 75.01 · TEMA · B36.10

A pocket suite of seven code-faithful calculators for piping & mechanical engineers — pipe sizing, friction loss, supports, ASME VIII vessels, pump sizing, control valves and shell-&-tube exchangers. Each tool computes to standard and exports a signed-style PDF & CSV datasheet, generated on the device.

The maker

Devil's Workshop is a one-person studio run by Upamanyu Chatterjee, a practicing piping & plant engineer. The software comes out of the same work it serves — pressure-vessel design, line sizing, the daily reality of running a plant department.

That's the whole idea: tools built by someone on the inside, who knows exactly what a result has to look like before it's any use to anyone.
