One job, done well.
Each app solves one problem for Atlassian Cloud teams. No suite. No bloat. A short list of features that work.
Transom · Studio
Focused apps for Atlassian Cloud. Private by design.
Transom is a small studio. We build one app for one job, and we run it entirely inside Atlassian. Your data stays on your site.
How we work
Three rules for every app.
01
02
Private by design.
We build on Atlassian Forge. Our apps run on Atlassian's infrastructure. We run no servers that touch your data.
03
Plain and reachable.
Clear prices. Docs that state the limits. Every support email gets a real answer: critical issues within 24 hours, all others within 5 business days.
The first app

Where your data lives
Inside your Atlassian site. Nowhere else.
Transom Diagrams has no backend of ours. The diagram is drawn in your browser, from source that sits on your own Confluence page.
