Description
Flame is an interactive coding platform for students and teachers. Write code, run tests, and watch it come alive with NeonFlow - the premium runtime visualization that turns variables and functions into a playable graph.
About Flame
What is Flame?
Flame is an interactive coding and teaching platform that provides step-by-step runtime execution animations through NeonFlow.
What Flame does
The platform turns programs into step-by-step animations showing every call, branch, and array swap with memory views. Teachers author problems with hidden tests, create classrooms with join links, and replay student runs in NeonFlow to see where logic went wrong.
Who Flame is for
Students writing code and teachers creating classrooms or grading programming problems.
How Flame works
Teachers post problems with hidden tests and share a classroom join link, students write code in the browser and trace execution in NeonFlow, and automated tests evaluate submissions in seconds.
Key features
- NeonFlow runtime visualizer animates call frames, conditional branches, and memory swaps.
- Supports seven programming languages: JavaScript, Python, C, C++, Java, Go, and Rust.
- Real sandboxed code execution evaluates solutions against hidden tests in seconds.
- Teacher dashboard manages student batches, pass-rate trends, and execution replays.
- Replays any student submission in NeonFlow to identify where logic went wrong.
- Run packs never expire, with 5 runs to try on new accounts with no card needed.
