We're also implementing a replay mode in Fray Debugger for developers tackling real-world concurrency bugs. Soon you'll be able to import execution recordings, eliminating the need to manually trigger bugs by clicking the 'Schedule' button thousands of times!

Even better, you can create your concurrency challenges by writing standard Java programs! We believe Fray Debugger is a powerful educational tool. It allows instructors to clearly demonstrate various thread interleavings while giving students hands-on experience with concurrent execution scenarios.
