Flee is an agent-based modelling toolkit which is purpose-built for simulating the movement of individuals across geographical locations, released under a BSD 3-clause license.
Flee is currently used for modelling the movements of refugees and internally displaced persons (IDPs), and is being extended to also support the transport of goods, and the spread of infections in that context. It provides users with the ability to define and use their models through a relatively straightforward application programming interface (API). There are a range of functional tests to allow users to verify the consistency of the code results. FLEE also features a range of scripts to handle and convert data, as well as an automated plotting tool for output generated by the simulation.
Detailed documentation of the current version of Flee is available at: https://flee.readthedocs.io.
