Signadot
Hi again HN, we’re Arjun and Anirudh, founders of Signadot (YC W20). Signadot helps teams developing microservices test their changes using lightweight environments called “Sandboxes”. We use a relatively new approach, using traffic labeling (using OpenTelemetry) and request routing (using a Service Mesh) to isolate environments in a shared Kubernetes cluster. Today, we’re launching a new feature to help developers with local testing of microservices during the iterative development process. When we initially launched in September last year…
Signadot launched on September 8, 2022 with 187 votes, #157 of 3,464 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 4 years on.
What it does
Signadot is changing the way DevOps teams think about test environments for microservices. Signadot allows you to create thousands of lightweight environments in Kubernetes to enable shift left testing for microservices.
Lightweight Kubernetes sandboxes for every code change from developers or coding agents. Validate against real dependencies without duplicating infrastructure.
Agents and developers collaborate on features. Rapid iteration on every change. Local agent connects to your live cluster via MCP or CLI. Sandbox ready in seconds. Agents run E2E and integration tests against the live cluster, debug failures, and iterate autonomously. Every PR auto-provisions its own sandbox in the cluster. Same Signadot platform. Plans and Jobs run integration, E2E, regression, and non-functional suites in Kubernetes. Validated in both loops. Ship code with high confidence in quality and behavior. Spin up your first sandbox on our playground cluster. No credit card, and no Kubernetes of your ownfrom signadot.com

SigNoz – open-source alternative to DataDog, NewRelic2022 · github.com · ▲510We just released a major upgrade to SigNoz with support for Logs management based on ClickHouse. Would love to get any feedback from the community here on what you think and any questions you may have for us Many big companies like Uber and Cloudflare have been shifting to ClickHouse as their main workhorse for Logs management seeing much better performance. for e.g Cloudflare recently shifted from Elastic to ClickHouse and are seeing 8x improvement in memory/cpu resource requirement in ingestion. This is our first release with Logs support and we have added support for: - Filtering…

KernoDec 2025 · kerno.io · ▲132Hey 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… none of that! Just a minimum effort, out-of-the box, highly contextualized and interactive experience so you and your team can focus on shipping! We basically scan your cluster resources, build usable abstractions on top of all the kubernetes craziness, identify monitor your…

Talanoa▲340Hi 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…

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
