Cova

What it does

Most monitoring tools tell you what's happening. None audit your full stack across multiple tools. Cova connects to your existing stack (Datadog, PagerDuty, Grafana, Sentry, New Relic, Sumo Logic, Splunk), scans everything in seconds, and gives you a health score with every coverage gap. AI generates production-ready fixes you can deploy with one click. Scan repos for unmonitored endpoints, flag missing monitors in PRs and MRs before code ships, and investigate incidents with AI Autopilot.

The agent that finds your monitoring blind spots, generates production-ready monitors, and deploys them. Connects to PagerDuty, Datadog, Grafana, Sentry, New Relic, and more.

  Hi HN! We’re the team behind Fiddler, and we recently built an Agent Cache feature. It works by capturing an LLM request/response pair and, once caching is enabled, serving subsequent matching calls locally so duplicate requests never hit the provider. It’s meant to reduce three pains that show up together in agent development: token cost, feedback-loop latency, and output non-determinism. We’d love to hear your thoughts.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
