Rent a Coder has release an industry comparison of virtual work sites for both buyers and workers. It is important to note that Rent a Coder produced the report on its own so let that influence your opinion on the issue after reviewing the rather detailed documentation.

The lists document the seven top marketplaces and compares them on their payment models (including details of pay-for-deliverable and pay-for-time), customer service, company success and stability, industry specific features and other miscellaneous features such as certifications and ratings systems.

"These lists were the result of several weeks of intensive research and compilation," says Ian Ippolito, CEO of Rent a Coder. "After they were finished, even I was surprised to see the vast differences between the marketplaces. These lists are an invaluable tool for consumers looking to be educated on those differences.”
