A Mac app for filing Radar bug reports and optionally crossposting them to Open Radar. Brisk is written in Swift and uses Sonar to communicate with Apple's Radar web APIs. Once logged in with your Apple ID, you are given a form to complete your bug report including attachments. You can save your report to a file as a draft or submit it straight to Radar. If you have an Open Radar account and API key, you can also choose to crosspost the bug report there.
