Pluralsight Flow vs. Upsource

Upsource is the best review tool we've found but it still has some flaws. Notably, it makes reviewing small and quick changes less convenient than they need to be, and diff viewing (especially collaboratively) can be tedious.

It does handle larger, iterative reviews well. Especially when using a feature branch, Upsource will track that branch and automatically add all commits to the review. You can then review the branch as a whole, or look at a subset of diffs.

Incentivized

• Automatically watch git repositories
• Track all commits in a branch in a single commit
• Integrates with build server to report build status of specific commits when looking at reviews/commits
• Integrates with JetBrains IDEs
• Ability for reviewers to add comments inline and require comments to be resolved before approval
• Built in diff viewer, both stacked and side-by-side

Incentivized

• Creating and closing reviews isn't as quick as it could be. You must create a review, assign reviewers, approve and close. I wish there would be a quick review-approve-close for a commit where the change is simple and doesn't require multiple review iterations.
• Web based interface can be clunky, especially when looking at big diffs side-by-side
• JetBrains IDE integration is somehow less convenient than going using it in browser.

Incentivized

Compared to the other tools we evaluated, Upsource was the only tool that allowed distinct reviews without needing explicit pull requests while still being able to go in-depth when required. The diff viewer is serviceable and better than the alternatives, as well, especially the side-by-side viewer.

Incentivized

• Increased our code base quality
• Reduced the number of bugs found after deployment (bugs are found in review and fixed before deploy)
• Improved knowledge sharing
