Sciagraph vs. Fil
Fil is a free, open-source memory profiler for Python. It shares some design goals with Sciagraph, but is also different in many ways.
|Use case||Data processing, but can also be used for any Python application||Data processing only|
|Memory profiling||✅||✅ with some limitations: uses sampling, so not useful for applications allocating <100MB RAM|
|Runtime overhead||Up to 40-50%||Negligible to ~5%|
|Supported platforms||Linux, macOS||Linux, macOS|
|Pricing||Open source, unlimited free use||Commercial software. Limited free plan, paid plans|
In more detail:
- Fil is open source, unlike Sciagraph.
- Sciagraph has performance profiling; Fil does not, it only does memory profiling.
- If you purchase the appropriate plan, Sciagraph can be used in production, unlike Fil.
- Fil can track much smaller memory allocations because it tracks all allocations; Sciagraph uses sampling so will only work well on applications that use more memory (100MB and up).
