PipeStep – Step-through debugger for GitHub Actions workflows
Hey HN — I kept seeing developers describe the same frustration: the commit-push-wait-read-logs cycle when debugging CI pipelines. So I built PipeStep. PipeStep parses your GitHub Actions YAML, spins up the right Docker container, and gives you a step-through debugger for your run: shell commands. You can: 1. Pause before each step and inspect the container state. 2. Shell into the running container mid-pipeline (press I). 3. Set breakpoints on specific steps (press B). 4. Retry failed steps or skip past others. It deliberately does not try to replicate the full GitHub Actions runtime — no…

In plain words
PipeStep is a step-through debugger for GitHub Actions workflows that eliminates the commit-push-wait cycle. It parses GitHub Actions YAML, spins up the appropriate Docker container, and lets developers pause before each step to inspect container state, shell into running containers, set breakpoints on specific steps, and retry or skip steps as needed. Designed for developers debugging CI pipeline failures locally, it focuses on shell command execution rather than replicating the full GitHub Actions runtime.

Interactive CI pipeline debugger. Step through GitHub Actions workflows locally with Docker. - Photobombastic/pipestep
Step through GitHub Actions workflows locally with Docker. Pause before each step, inspect the environment, drop into a shell, modify variables, re-run failed steps — without pushing and waiting. A single debugging session eats 30-60 minutes. PipeStep lets you step through the pipeline locally, inspect the container at each stage, and fix issues before you push. # Prerequisites: Docker Desktop running, Python 3.11+ pip install pipestep # or from source: python3.11 -m venv .venv source .venv/bin/activate pip install -r requirements.txt # Pre-pull the base image docker pull ubuntu:22.04 Requires Python 3.11+ and Docker Desktop running. # Point it at any GitHub Actions workflow in your project…from github.com

Pipet – CLI tool for scraping and extracting data online, with pipes2024 · github.com · ▲49I often find myself in situations where I need to extract some data from a website, either as one time thing or periodically (and then watch for changes). Maybe I'm tracking stocks, or a delivery, or I want to know when tickets become available to the local sauna; maybe a friend called and asked "can you get me all data from that website into a spreadsheet?" (this happens surprisingly often) I used to write one-off scripts for that, often with Python or JavaScript, but I noticed I spend about one minute getting the right CSS selectors, and then another 10 minutes setting the rest of the…

Hey HN! I'm Jacob, one of the founders of Depot (https://depot.dev), a build service for Docker images, and I'm excited to show what we’ve been working on for the past few months: run GitHub Actions jobs in AWS, orchestrated by Depot! Here's a video demo: https://www.youtube.com/watch?v=VX5Z-k1mGc8, and here’s our blog post: https://depot.dev/blog/depot-github-actions-runners. While GitHub Actions is one of the most prevalent CI providers, Actions is slow, for a few reasons: GitHub uses underpowered CPUs, network throughput for cache and the…

Talanoa▲340Hi 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…
