Small tools, machined one at a time

A mill takes a rough billet and cuts it down until only the part is left. That is the whole idea here. One small program. One job. No dashboard, no account, no subscription — you buy the thing, you download the thing, it is yours.

01What we make

Software the size of a hand tool

Most developer software wants to be a platform. OpusMill does not. Every tool sold here is a single executable or a single script that solves one irritating problem and then gets out of the way.

They are built for people who already know what they are doing and just want the annoying part to stop. No telemetry. No login. No call home. The tool runs on your machine and answers to you.

02On the bench

Nothing is finished yet

Honest status

OpusMill opened on 6 September 2026 and has not sold anything yet. The first tool is still being cut. This page exists so you can see what is coming and decide whether it is worth watching. When something ships, it will appear here with a price and a download.

These are the kinds of jobs on the list. Nothing here is for sale today, and none of it is promised on a date.

Windows path repair Finds the tools that break on folder names containing a space, and reports exactly which call fails. Written because it cost a whole afternoon. Being cut

Bundle inspector Opens a minified JavaScript bundle and pulls out the parts that matter — hardcoded paths, platform checks, shell calls — without a debugger. In the queue

Domain sweep Checks a list of names against the registries themselves rather than a reseller, so the answer is the record and not an upsell. In the queue

03How buying works

Pay once, download, done

You pick a tool and pay for it. Card payments are handled by Stripe — OpusMill never sees or stores your card details.
You get a download link, immediately, plus a copy by email.
The tool is yours. It keeps working whether or not this shop does. There is no licence server to phone home to.

Prices are shown in full before you pay, in US dollars, tax included where it applies. There is no subscription and nothing renews. If a tool is not right, see the refund policy — it is short.
