We got tired of paying a monthly fee for everything.

Software we already own gets a feature pulled behind a higher tier. A tool we used for years turns into a subscription. A simple thing we need every day on a job is sold back to us at a price that makes no sense for the size of the problem.

So we started building the small things ourselves. This is where we put them.

A growing library of free tools for people who work in engineering and construction. Design, drafting, drawings, markups, takeoffs, submittals, field documentation, the file formats and the software that sit in the middle of all of it. Small tools that do one job. Connectors that let AI assistants work with the software you actually have installed. Scripts that replace a paid add-on with a few hundred lines of code.

Everything here came out of real work. Someone needed it, built it, used it on a project, and cleaned it up enough to share. None of it is polished product. All of it works, because we use it.

The first one is revu-mcp, an MCP server for working with PDF drawings and markups when Bluebeam Revu is on the machine. More are on the bench and will land here as they are ready.

Free for personal and non-commercial use under the PolyForm Noncommercial License. If you want to use something here inside a business, open an issue and ask. We're not against it, we just want to know.

Nothing here cracks, patches or works around a vendor's licence. When a feature isn't licensed, our tools do the job another way or tell you they can't. No vendor software, documentation or files are redistributed. Product names are only used to say what a tool works with. We're not affiliated with any of those companies and they haven't endorsed any of this.

This is a few people doing this around their day jobs, and the list of things worth building is a lot longer than the list of people building them. We want to grow this into a real library, maintained by the people who use it.

If you work in engineering or construction and can write code, you'll find plenty to do. If you can't write code but can test a tool against software we don't have, write a clear bug report, or tell us which paid feature you'd most like to stop paying for, that's just as useful.

• Pick an open issue and comment on it.
• Pull requests are reviewed. Keep them small and say what problem they solve.
• Built something of your own that fits? Open an issue and tell us about it.
• Want to own a tool or a whole area? Say so. We'd rather hand things over than hoard them.

No roadmap, no deadlines, no support contract. Just people in the trade fixing the things that annoy them, in the open, for anyone with the same problem.
