FCA Software

5 examples of contexts/lattices (with downloadable cxt files)
FcaStone online demo (editing a small, 4x4 context on-line and generating lattices from it)
Credo (Yahoo front-end which uses FCA in the background) or as a mobile version
Concept Neighbourhoods in Roget's Thesaurus (shows concept lattices)
Lattice Drawing Software (lattices in general, not FCA-specific, Java applet/download)
Virtual Museum of the Pacific (uses FCA in the background as explained in this youtube video)
KFCA demo (data mining).
Confexplore demo (requires Adobe Air)

Tockit, Score, ToscanaJ, Tupleware at sourceforge, ( Manual, etc, about Siena)
ConExp Concept Explorer (Java) at sourceforge
Galicia
FcaStone format conversion software and command-line lattice generation
Camelis (Logical Information System based on FCA)
Christian Lindig's Colibri (Java or ML), Concepts (in C), TkConcept (Tcl/Tk, graphplace) also in Python
Conexp-clj (alpha version)
Contextual Role Editor (works with Eclipse)
Coron System (data mining software)
Eclipse's Relational Concept Analysis
FCA algorithms
FcaBedrock (tool for creating contexts from csv files)
Formal Concept Calculator (in PHP)
Griff by R. J. Cole
In-Close (fast Formal Concept miner)
Latex style file for FCA
Lattice Miner
Lattice Navigator (lattice visualisation and context editing, written in C#)

FCA Extension for Excel (with screenshots and video)
FcaView Tab Plugin ( old website). A Conexp plugin for Protege.
OntoComP Another Protege Plugin; implements attribute exploration. Also by the same author: FcaLib (Java Library) FCA API.
FcaJava (eclipse plugin for exploring java)
Notes on how to use FCA with Sage and NetworkX
seem to be no longer available: Mail-Sleuth (a commercial FCA Outlook Plug-in), Hiermail (similar to Mail-Sleuth but free for academic use)

Other Software:

Cernato (commercial software) by former company NaviCon.
ConImp, Toscana, Anaconda, FCA Library, Diagram, MBA (former FCA group of the TU Darmstadt), only ConImp is still available.
epi-ACE (for "examining the hierarchical data structure of small epidemiological data sets").
Galoisexplorer by Sebastian Breuers ?, looks interesting, but no documentation as far as I can see.
GLAD (General Lattice Analysis and Design), a DOS program, available from Vincent Duquenne.
JaLaBA (On-line Java lattice drawing tool).
Jupp's FCA (not yet released, but looks interesting, developed in Python)
QuDa (for data mining by P. Grigoriev, S. Yevtushenko).
RubyFCA
Scola (Shell for Contextual Logic Applications).
Semana (software for semantic analysis which includes an FCA tool).
Yacaree (association miner, not a typical FCA tool, but uses an iceberg lattice of frequent closures internally, written in Python).
