GRwiki - A repository of basic definitions and formulas for gravitational physics. It is meant to serve as a high-level tool for active GR researchers, not a place to learn the theory.

Codes - Freely available codes

VIPER - "Visual Interactive Physics Education Resource" is a tool for simulating and modeling mechanics problems.
