Frequently asked
Is it really free?
Yes. The browser app and the desktop apps are free with no sign-up and no diagram limits.
How do you make money?
Today, we don't. Bowtie Risk Engine started as a tool for engineers who needed something faster than the enterprise options. If a paid tier ships in the future — for example, team sharing, version history, or SSO — the current free experience will stay free.
Will the free tier change?
The current free experience — unlimited diagrams, browser app, desktop apps, all export formats — will not get worse.
Do you offer enterprise licensing or support?
