GTKWave is a fully featured GTK+ based wave viewer for Unix and Win32 which reads LXT, LXT2, VZT, FST, and GHW files as well as standard Verilog VCD/EVCD files and allows their viewing.

Keyvi - the key value index. It is an in-memory FST-based data structure highly optimized for size and lookup performance.

Rust re-implementation of OpenFST - library for constructing, combining, optimizing, and searching weighted finite-state transducers (FSTs). A Python binding is also available.

Keyvi - a key value index that powers Cliqz search engine. It is an in-memory FST-based data structure highly optimized for size and lookup performance.

An efficient OpenFST-based tool for calculating WER and aligning two transcript sequences.

A local reactive cache for Java and Android. Now, it supports heap memory、off-heap memory and disk cache.
