Crocodile - Better code review for GitHub

Hi HN! I've been working on a code review app for GitHub called Crocodile for about a year. I used to work at Microsoft where we used a tool called CodeFlow for reviewing code and I missed it after I left. I know many other ex-Microsoft engineers feel the same. Here are some of the distinguishing features of Crocodile that are inspired by CodeFlow: * Comments float above the code instead of being inline. Long discussions that are displayed inline make it really hard to review the code. * Comment on any text selection in the file, even a single character. * Comments don't get lost when code…

In plain words

Crocodile is a code review tool for GitHub that displays comments in floating panels above code rather than inline, making it easier to review without long discussion threads obscuring the code. Reviewers can comment on any text selection, including individual characters, and comments persist even when code changes or is rebased. The tool was inspired by Microsoft's CodeFlow and built for developers who want a streamlined review experience.

    Hey everyone, Just wanted to share a quick update we just launched at Kodus. For those who don’t know it yet, Kodus is a code review agent that runs directly in your team’s Git workflow (GitHub, GitLab, Bitbucket… and now Azure DevOps as well). It helps maintain code quality and consistency by analyzing each PR based on your team’s own rules and repository standards. Support for Azure had been a common request — so if your team uses it, you can now plug Kodus right into your workflow and give it a try. Docs: https://docs.kodus.io/how_to_use/en/overview Repo:…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…
