SPMF is fast, stable and lightweight (no dependencies on external libraries), and actively developed.

SPMF can be used in five different ways:

• From languages such as Python, R, and C# via wrappers or SPMF's command line interface.
• Through REST queries from Web or Python clients using the SPMF-Server project
