The FIX message viewer is a set of Ruby scripts that parse FIX (Financial Information eXchange protocol) messages to display them in a more human-readable format. The viewer can only parse FIX messages in a file or from STDIN. It also expects a full FIX message on each line. The FIX message can be prepended with a timestamp, but this will be ignored. The output is colored to make it easier to read, and the MsgType field is highlighted. The log viewer works on the command line only, and requires that Ruby is installed.
QuantLib is a cross-platform, quantitative finance C++ library for modeling, pricing, trading, and risk management in real-life. It is also wrapped as Python/Ruby/Scheme modules.

It features market conventions, yield curve models, solvers, PDEs, Monte Carlo (low-discrepancy included), exotic options, VAR, and so on.
OutGoing is a Perl script that is designed to aid with financial planning.

finic helps users manage their finances. It can be used on a local network (as a client-server system for many users) or on local computer (client only for one user), with separation of accounts, clauses, and customers. It can encrypt information and manage different users with different access rights. Reports can be generated as HTML, PDF, or XLS files or through an internal print preview system. An API is available for creating extensions.
QuoteFilter is a companion to Xinvest and Xquote. You can use it to filter your emails messages and process the contents of some messages to retrieve stock quotes from them. The quote information can be stored in the files that Xinvest uses so that you'll automatically use recent information. Xquote serves a similar purpose, but it retrieves stock quote information from Internet servers.
