Sails are tested with node versions 0.10.x and up, though we recommend using at least Node v4.0.@The framework is built on the rock-solid foundations of Express and Socket.io. Out of the box, it also depends on other great modules, like grunt, waterline, and fs-extra. Click the badge above for the full list of dependencies in the latest stable release of Sails core.

Sails Flagship users: We manually verify every dependency of Sails and other officially-maintained modules by hand, every single week. This includes core hooks, adapters, generators, client SDKs, and Flagship packages.
