Kerno

In plain words

Kerno.io is a monitoring and troubleshooting tool designed for developers working with Kubernetes clusters. It automatically scans cluster resources and creates simplified abstractions to identify service interactions and trace errors without requiring complex setup, custom infrastructure, or extensive instrumentation. The platform integrates with code versioning and CI systems to provide contextualized insights, helping developers understand end-user impact and prioritize issues efficiently.

From the sources

Never manually write, or and maintain backend tests again! Kerno automates integration testing end-to-end inside your IDE. It understands your codebase, generates meaningful tests, spins up test environments, executes tests, and delivers instant audit reports to catch issues early, validate changes before committing your code. Use Kerno to: → Catch breaking changes at source → Augment current Code-Gen loops with test data → Audit AI generated code in real-time → Increase test coverage

Kerno writes and runs backend tests against your running app and real dependencies, catching the regressions and security issues code review and AI-written tests miss.

Runs in every coding session against your running app and dependencies to catch real regressions and security issues your agent and code review tools miss. Your coding agent's tests carry the same blind spots as its code. Static review only catches the obvious, and manual checking doesn't scale. Slop piles up, draining engineering time and slowing releases. Give every developer and agent staff-level testing knowledge to catch the expensive runtime issues DIY testing and code review miss, right at the source. Kerno catches the functional and security bugs that only surface at runtime, before they ship. Kerno maps the blast radius of a change and tests every path it touches. Kerno gives…from kerno.io

In the maker’s words, at launch

Hey HN! Anibal, Sean, Vlad, Maxi and Karim here we're the co-founders of Kerno (https://www.kerno.io/). We're building a zero-hassle tool to help developers monitor and troubleshoot their services in a way that makes sense. No complex rollouts, no custom infra, no tons of instrumentation, no sidecars……

  Koreo – A platform engineering toolkit for Kubernetes2025 · koreo.dev · ▲120

  A large part of our (Real Kinetic's) business is helping organizations implement platform engineering, but we've found the existing tooling to be lacking. For IaC, Terraform state becomes a pain because TF treats infrastructure as "one-shot" commands. The Kubernetes controller model provides a nicer approach to managing infrastructure, but the tooling here is also lacking. For configuration management, Helm just doesn't really scale with complexity, nor does Kustomize. For resource orchestration, Crossplane is a step in the right direction but still has challenges and limitations. As a…

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser.
