24 alternatives to Automate Expo QR Code Previews in GitHub PRs

Hey HN, Inspired by Vercel’s automated preview deployments, I built a GitHub Actions workflow that generates an Expo QR code per PR—so mobile previews are as easy as scanning a QR code. How it works: • Every PR triggers a GitHub Action • The action starts an Expo server • It posts a QR code in the PR comments for instant testing on mobile No more manually starting Expo. No more copying links. Just open a PR and scan the code. Full guide here: https://torii.studio/guides/expo-qr-previews Would love to get feedback—how would you improve this workflow?

   A GitHub Action that quizzes you on a pull request▲94

   A little idea I got from playing with AI SWE Agents. Can AI help make sure we understand the code that our AIs write? PR Quiz uses AI to generate a quiz from a pull request and blocks you from merging until the quiz is passed. You can configure various options like the LLM model to use, max number of attempts to pass the quiz or min diff size to generate a quiz for. I found that the reasoning models, while more expensive, generated better questions from my limited testing. Privacy: This GitHub Action runs a local webserver and uses ngrok to serve the quiz through a temporary url. Your code…

    Pullpo – Code review conversations on Slack▲23

    Code review conversations on GitHub can be frustratingly slow, now you can have them on Slack. Features: - Each pull request (PR) on GitHub creates a Slack channel (public or private) with all involved parties (creator, assignees, and reviewers). - An auto-generated summary in English of what the PR does, making it easier for reviewers to enter the context. - Notifications of workflow results, new commits, new approvals... are sent in the channel. - Code comments with context are available. The initial review still takes place on GitHub, but messages are then transferred to Slack for…

    Get paid to get ephemeral environments for every PR (Livecycle.io)▲8

    We've build a front-end dev tools platform called Livecycle - https://livecycle.io/. Livecycle lets dev teams review code faster by enabling them to collaborating on top of ephemeral environments. Livecycle creates a live preview environment "playground" for every PR. Collaborators (both technical and non-technical) can join the playground, review and leave comments on top of the preview environment itself. Comments are also synced to Git, making the code reviews faster and feedback clearer. And since all reviews (even the less-technical ones) are done instantly and…

    Free QR Code Generator▲18

    Hi HN, I built a small QR code editor after repeatedly running into the same problem: once a QR code is printed, the destination is frozen. This tool supports both: Static QR codes (generated entirely client-side) Dynamic QR codes (editable destination after creation) Dynamic QR codes come with a minimal dashboard where you can: Update the QR destination without reprinting See basic scan stats (count, device, time, approximate origin) I intentionally kept the feature set small and avoided heavy analytics or tracking. The goal is something simple that works well for menus, flyers, events, and…

    GitHub Plugin that generates launch tweets when you ship new code▲15

    Hey HN! I just shipped a project I’ve been working on called Buildshare. Demo: https://www.youtube.com/watch?v=CsacqlCHlzE How does it work? 1. Enter some info about a product that you’re building 2. Connect your Github + install a plugin on the repository of the product 3. Every time you ship new code (by either merging a pull request or making a commit), you get a tweet generated automatically with GPT to announce the new feature. Generated tweets follow best practices that are optimised for grabbing people’s attention and making them want to check out what you’ve built.…
