ChaCha recently launched with a service and Sketch plugin that offers users another option for sharing files, specs and group feedback – all targeted at bridging the gap between designers and developers. As ChaCha puts it, they are: “The powerful collaboration platform for designers and developers. You can download ChaCha plugin for Sketch, export your designs to ChaCha, and share them with your teammates easily and accurately.”
At the moment the service appears to be free. It will be interesting to see if their pricing strategy and feature set can compete with other similar services that have gained notable market traction, such as: Zeplin, Avocode, Simpli and Markly.
