Back the team
Built by a small team.Shaped by you.
Arsenal is made by a small team at Speedloop Technologies. Every role keeps a free tool. Premium tools are how we pay for the next ones, and you decide what we build next.

Why we charge
Free where it counts. Paid where it builds.
Free tools that stay free
Every role keeps one free tool (24 today), and it opens without an account. That doesn't change when we add premium tools.
Premium tools pay for the next ones
We're a small team. What you pay for a role plan goes into new tools, fixes and more free picks.
Fixed and added often
We fix and add tools often. A tool fixed for one person is fixed for everyone, because every tool comes from one shared catalogue.
How you can help
Four ways to back us.
Use a free tool
Run your role's free tool on a real job. If a number looks wrong, tell us and we'll check the maths.
Ask for a tool
Tell us the calculation you still do on paper. The good ones go on our build list.
Share it with your crew
Send a tool to the person who always does the maths on site. That's how a small team gets found.
Unlock a tool when it earns its keep
If a premium tool earns its place on your job, unlocking it keeps the next one coming.
Ask for a tool or a feature.
Tell us your role, the job, and the numbers you work with. We read every request. Please don't send passwords, card numbers or other people's personal details.
