AppView 1.0.0 is released Instrument, Observe, Secure your deployments

In plain words

AppView is an open source instrumentation utility for Linux applications that provides visibility into performance, security, and behavior without requiring code changes. It works across all runtimes with a single approach and can monitor unmodified executables to detect suspicious activity like unauthorized file access, unexpected connections, and data exfiltration. The tool generates metrics, events, and traces related to network activity, file operations, and HTTP communications, and can capture payload data for analysis. It is designed for developers and operations teams who need deep observability of their deployments.

From the sources

AppView is an open source instrumentation utility for any application, regardless of its runtime, with no code modification required. Collect only the data you need for full observability of your applications, systems and infrastructure.

AppView provides application-centric instrumentation and data collection. With one instrumentation approach for all runtimes, AppView offers ubiquitous, unified instrumentation of any unmodified Linux executable for single-user troubleshooting or distributed deployments. Use the simple command line to easily instrument and inspect any application or Linux command, regardless of runtime, including Go binaries. There’s no need for any code modification, or a man in the middle proxy. It’s like strace meets tcpdump, but with readily consumable output. You can even attach to already-running applications. Send application information, wire and log data, and performance metrics to existing log…from appview.org

AppView is an open source, runtime-agnostic instrumentation utility for any Linux command or application. It helps users to explore, understand, and gain visibility with no code modification. With one instrumentation approach for all runtimes, AppView offers ubiquitous, unified instrumentation of any unmodified Linux…

  Alaz: Open-Source, Self-Hosted, eBPF-Based K8s Monitoring2023 · github.com · ▲101

  Hello Everyone, I'm excited to introduce a new open-source observability platform and would love to hear your feedback. We are aware that there are lots of open-source/commercial tools out there. However, we believe that monitoring the clusters and extracting actionable insights requires deep know-how about the tools/domain. We mainly focused on this problem. - Alaz is an eBPF agent installed on your K8s cluster as DaemonSet. Thanks to eBPF, Alaz collects traces directly from Linux kernels. This means there's no need for sidecars, instrumentations, or service restarts. - The UI not…

  Osint tool that finds exposed files on domainsJul 2026 · search.cerast-intelligence.com · ▲58

  hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

  Talanoa▲346

  Hi 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…
