I like how easy it is to track changes and comments as well as resolving them. The tree structure of all changed files is pretty neat, as well as line comments. The statistics and badges are a good way to encourage users as well.The news feed is amazing to get a quick glimpse of the latest activity on your review/things you're reviewing. The browser and email notifications work great.
What do you dislike?
The UI is not the most intuitive at first - many of my colleagues have created reviews on commits instead of the whole branch. But with regular use, it becomes better. Not much else to complain about really.
Recommendations to others considering the product
Make sure to check out the settings available as you're able to customize your view somewhat (there's two layouts for reviews currently - I find one easier to use than the other)
What business problems are you solving with the product? What benefits have you realized?
We are solving the problem of not outputting buggy code and having less bug fixes.
* We monitor all Upsource reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. Validated reviews require the user to submit a screenshot of the product containing their user ID, in order to verify a user is an actual user of the product.
