What it is and what it does
djdt-flamegraph is a Django Debug Toolbar panel that generates flame graphs of request execution in real time during development. It hooks into the debug toolbar UI and visualizes CPU time spent across the call stack, helping developers spot performance bottlenecks in their Django applications.
The package wraps the FlameGraph tool and requires a single-threaded development server to function—it cannot generate graphs in multithreaded environments due to signal handling constraints. Flame graphs are disabled by default and must be explicitly enabled via a checkbox in the toolbar. The project has been archived and receives no active maintenance.
Use it for
- Identify which functions consume the most CPU time during a specific Django request
- Visualize call stack depth and branching to spot unexpected recursion or inefficient code paths
- Compare flame graphs across different request types to understand relative performance characteristics
- Debug performance regressions by comparing flame graphs before and after code changes
