What it does
Crashguard is a self-hosted (LGPL3) canary-oriented monitoring system for asynchronous workflows — background jobs, cross-service pipelines, anything where "it should finish by X" matters more than any single log line. The model is simple: start a canary when a workflow kicks off, resolve it when the workflow finishes. If the canary doesn't resolve before its deadline, Crashguard fires an alert immediately — no log scraping, no complex alerting rules. Also comes with a stream deck XL+ plugin.
Start a canary the moment a workflow kicks off. Resolve it the moment it finishes. If your workflow times out, CrashGuard alerts you the moment it happens. Traditional monitoring watches what already happened, after the fact, and asks you to guess what a failure looks like in a sea of log lines and metrics. CrashGuard is different. Start a canary from anywhere with the C#, Go, or Rust SDK when an asynchronous workflow kicks off. Mark the canary resolved from anywhere else once the workflow has completed successfully. If a canary doesn't resolve in time, CrashGuard flags it immediately so you can investigate. Resolving a canary doesn't have to mean "trust the caller." Attach a custom…from crashguard.io

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…

The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
