salabim - discrete event simulation in Python
Decision gist · record as of 2026-08-14
Yes. Salabim is a mature, actively maintained library with zero known vulnerabilities, low install friction, and permissive licensing. It is well-suited for anyone building discrete event simulations in Python, particularly those who prefer intuitive process description over yield-based coroutines. The built-in animation and data collection features add significant value for modeling and analysis workflows.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.7 or later; animation features may require additional system libraries depending on your platform.
- Low install friction with no runtime dependencies; wheel-only distribution.
- Package is actively maintained with recent releases and a stable production status.

What it is and what it does
Salabim is a discrete event simulation framework designed for modeling systems found in logistics, manufacturing, healthcare, and network analysis. It provides an object-oriented API with components, queues, resources, stores, and state tracking, allowing you to describe processes intuitively without yield statements. The library includes built-in data collection via monitors, 2D and 3D animation capabilities, tracing for debugging, and statistical sampling tools.
The package is cross-platform (Windows, macOS, Linux, iOS/iPadOS) and has minimal dependencies when animation is disabled. It follows a well-established process description method and is actively maintained with comprehensive documentation. The core developer provides direct support and consulting services.
Use it for
- Model production facility workflows, material handling, and resource allocation to optimize throughput and identify bottlenecks.
- Simulate airport operations, hospital patient flows, or warehouse logistics to evaluate system designs before implementation.
- Analyze computer network behavior and packet routing under various load conditions.
- Create animated visualizations of simulations for stakeholder presentations or educational demonstrations.
- Collect and analyze statistical data from repeated simulation runs to support decision-making.
