   Safe-NPM – only install packages that are +90 days old▲90

   This past quarter has been awash with sophisticated npm supply chain attacks like [Shai-Hulud](https://www.cisa.gov/news-events/alerts/2025/09/23/widesprea...() and the [Chalk/debug Compromise](https://www.wiz.io/blog/widespread-npm-supply-chain-attack-b...). This CLI helps protect users from recently compromised packages by only downloading packages that have been public for a while (default is 90 days or older). Install: npm install -g @dendronhq/safe-npm Usage: safe-npm install react@^18 lodash How it works: - Queries…

    Ciara – Securely deploy any application on any server▲5

    Hey HN! Coolify and Kamal were "nice" (Kamal docs are pretty bad, actually), but I still had to configure firewalls, unattended-upgrades, and Fail2ban every single time. Ciara does all of this from a single configuration file. Features: Integrated Firewall Automatic System Updates Zero-Config OS Ready Zero-Downtime Deployments Automatic HTTPS support Multiple Servers Deployments Would love your feedback and happy to answer any questions!

    OSS sustain guard – Sustainability signals for OSS dependencies▲21

    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…

    Quorum-free replicated state machine built atop S3▲6

    Hi HN, I’m sharing the alpha release of S2C, a state machine replication system built atop S3. The goal is to enable a distributed application to maintain consistent state without needing a quorum of nodes for availability or consistency. The idea came from a side project that was using S3 and where I needed strongly consistent distributed state but wanted to avoid adding a separate consensus dependency. I initially tried to use S3 directly for coordination, but it became messy. Eventually, I realized I need a replicated state machine with a deterministic log, and then it ended up as a…
