Choose heron if…
- heron is primarily Rust; scalene is Python.
- Tags unique to heron: agentic-ai, ai-agent-development, libpcap, llm-monitoring.
- When you need a provider-side solution that does not require altering existing codebases or SDKs to monitor performance metrics.
When NOT to use heron
- When the need is for an in-agent monitoring tool rather than a network packet-based solution, as Heron operates on traffic.
- In environments where live capture requires administrative privileges that are not available to the user performing the installation.
- For real-time performance insights without prior deployment because Heron involves a setup phase and typically uses pre-collected `.pcap` files.
Choose scalene if…
- scalene is primarily Python; heron is Rust.
- Tags unique to scalene: cpu-profiling, gpu-programming, memory-allocation, profiler.
- When you need precise profiling of both CPU and GPU performance in Python applications
When NOT to use scalene
- If your project does not involve Python, as Scalene is specific to this language
- Avoid if your system lacks necessary dependencies like Visual C++ Redistributable on Windows
