uGoLive was incorporated with Umbraco in v4.7.1. Which was superseded by the Health Checks feature in Umbraco v7.5.0. The standalone package version of uGoLive is no longer being maintained.
uGoLive is an Umbraco dashboard control which allows you to run a series of checks on your website in order to prepair it for launch. uGoLive comes complete with the most fundamental checks to ensure your site is as secure as possible, however uGoLive is completely pluggable so can be easily be extended to include your own checks. In this way, you will be able to build up your own set of checks that you can test your website against each and every launch. No more forgetting whether you remembered to update a setting, run the check and uGoLive will tell you.
How to use:
To use, simply click the "run all checks" button, or the "run check" button next to a specific check to peform the check(s). Once run, any checks that are auto-rectifyable can be rectified by simply clicking the "rectify check" button for that check.
How to create your own checks:
For a guide on how to perform your own checks, checkout the "check developers guide" under the documentation tab below.
If you do create your own checks, why not concider contributing them to the community. Contributions can be made by forking the uGoLiveContrib repo here:
Simply create your own checks in your forked copy of the repository, and submit a "pull-request" to have it included in the main uGoLiveContrib repo for everyone else.
