Mo

What it does

Your team agrees on something in Slack. Two weeks later a PR quietly breaks it. Nobody catches it until QA — or after deploy. Mo watches a Slack channel for decisions. When someone tags @mo to approve something, it stores it. When a PR opens, Mo checks the diff against every approved decision and flags conflicts before merge. It doesn't review code quality. It only cares if the code matches what the team actually decided.

Mo is the enforcement layer that turns team decisions into merge checks. Captured in Slack, Teams, Jira, Linear, Azure DevOps, Asana, Monday and Basecamp. Checked in GitHub, GitLab, and Bitbucket pull requests before merge.

Only messages explicitly approved with @mo approve become enforced rules. Regular conversation is ignored. Sources: Slack, Microsoft Teams, Jira, Linear, Azure DevOps, Asana, Monday and Basecamp. Code hosts: GitHub pull requests, GitLab merge requests, and Bitbucket pull requests. The newer approved rule replaces the older one. Mo keeps the latest approved version with versioned history, and checks every new change againstfrom hey-mo.io

  Mo – checks GitHub PRs against decisions approved in SlackApr 2026 · motionode.com · ▲10

  Built this after a recurring frustration at our agency: the team would agree on something in Slack ("only admins can export users"), someone would open a PR two weeks later that quietly broke it, and nobody caught it until QA or after deploy. Mo watches a Slack channel for decisions. When someone tags @mo to approve something, it stores it. When a PR opens, Mo checks the diff against the approved decisions and flags conflicts before merge. It doesn't review code quality. It only cares whether the code matches what the team actually agreed to. Would love feedback, especially from anyone who's…

  Talanoa▲341

  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 built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
