OSS sustain guard – Sustainability signals for OSS dependencies
Hi HN, I made OSS Sustain Guard. After every high-profile OSS incident, I wonder about the packages I rely on right now. I can skim issues/PRs and activity on GitHub, but that doesn’t scale when you have tens or hundreds of dependencies. I built this to surface sustainability signals (maintainer redundancy, activity trends, funding links, etc.) and create awareness. It’s meant to start a respectful conversation, not to judge projects. These are signals, not truth; everything is inferred from public data (internal mirrors/private work won’t show up). Quick start: pip install…

In plain words
OSS Sustain Guard analyzes open-source software dependencies to surface sustainability signals like maintainer redundancy, activity trends, and funding information. Built for developers managing tens or hundreds of dependencies, it scans GitHub data locally to identify potential risks without uploading sensitive information. The tool supports multiple ecosystems including Python, JavaScript, Rust, Go, and Java, and is designed to start conversations about project health rather than render judgments, using only publicly available data inferred from GitHub activity.

Multi-language package sustainability guide and CLI documentation
OSS Sustain Guard is a multi-language package sustainability analyzer that helps you understand the health of your dependencies across ecosystems. The tool provides constructive insights about maintainer activity, community engagement, security posture, and funding signals so teams can make informed decisions about the projects they rely on. Note: Demo shows a warm cache; first run may take longer depending on API response time. Every time a high-profile OSS incident makes the news, I find myself wondering about the packages I rely on right now. I could visit GitHub and skim issues, pull requests, and activity to get a rough sense, but it is not easy. When you depend on tens or hundreds of…from onukura.github.io

Keep – GitHub Actions for your monitoring tools2023 · github.com · ▲181Hi Hacker News! Shahar and Tal from Keep here. A few months ago, we introduced here at HN (https://news.ycombinator.com/item?id=34806482) Keep as an “open source alerting CLI” and got some interesting feedback - mainly around UI, automation, and supporting more tools. We were VERY early back then, and we understood that although the current DX around creating alerts is not great, it's not that critical and developers don’t need another tool just for that. But we did find something else. While talking to developers and devops, we found that a lot of companies use many tools…
I built a tool for policy driven vetting of open source packages2023 · github.com · ▲7Linux Foundation survey says 70-90% of modern software constitute OSS code. Yet we are stuck with tools that scan only for vulnerabilities in 3rd party libraries and that too with high degree of false positives. I built `vet` for policy and data driven analysis of 3rd party packages that goes beyond only vulnerability and allows codifying organisational policies related to OSS consumption. https://github.com/safedep/vet Looking forward to feedback and suggestions from HN :)
Keep – Open-source alerting CLI2023 · github.com · ▲65Hi Hacker News! Shahar and Tal from Keep here. We're thrilled to announce that we're open-sourcing our alerting CLI tool, Keep (https://github.com/keephq/keep). Designed by developers for developers, Keep streamlines and simplifies alerting, making it a first-class citizen within the development process. Think of Keep as Prometheus Alertmanager but for all observability tools, with a simple and intuitive (GitHub actions-like) syntax. We believe that alerting has historically been neglected in existing monitoring platforms, leading to subpar alerting practices. With Keep,…

Talanoa▲346Hi 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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
