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. Extensions for Excel, R, and Mathematica are available. Other such extensions are under consideration. QuantLib offers tools that are useful both for practical implementation and for advanced modeling. It features market conventions, yield curve models, solvers, PDEs, Monte Carlo (low-discrepancy included), exotic options, VAR, and so on.
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.
