VoTT
Visual Object Tagging Tool, an electron app for building models
...VoTT can be installed as a native application or run from source. VoTT is also available as a stand-alone Web application and can be used in any modern Web browser. VoTT is available for Windows, Linux and OSX. Download the appropriate platform package/installer from GitHub Releases. As noted above, the Web version of VoTT cannot access the local file system; all assets must be imported/exported through a Cloud project. VoTT V2 is a refactor and refresh of the original Electron-based application. As the usage and demand for VoTT grew, V2 was started as an initiative to improve and make VoTT more extensible and maintainable.
