[DevOps] Show HN: Edka – Kubernetes clusters on your own Hetzner account Hi HN,<p>I’ve been working with Kubernetes for over a decade, since the alpha days, and was involved in kube-aws project before AWS launched EKS. For the past four years, I’ve been helping friends and small businesses cut costs by running Kubernetes on Hetzner Cloud, which I’ve found to be rock solid and by far the best priced provider.<p>Provisioning a cluster on Hetzner is now straightforward, thanks to tools like k3s and hetzner-k3s, but configuring it for your specific needs still takes time and expertise. I built Edka to make that part easy: spin up a production ready cluster in ~2 minutes, then choose how low level or automated you want to go.<p>How it works:<p>Layer 1 – Cluster provisioning - Creates a k3s-based Kubernetes cluster on Hetzner (lightweight, easy to manage, scales well).<p>Layer 2 – Add-ons - One-click deploy for metrics-server, cert-manager, and various operators; preconfigured for Hetzner, no extra setup needed.<p>Layer 3 – Applications - Minimal config UIs for apps built on top of add-ons. - Example: Need PostgreSQL? Fill a few fields → platform installs CloudNativePG → provisions HA PostgreSQL with PITR → gives ready to use endpoints. Backups can be restored to any point in time with a click. Quick demo: <a href="https:&#x2F;&#x2F;edka.io&#x2F;apps&#x2F;" rel="nofollow">https:&#x2F;&#x2F;edka.io&#x2F;apps&#x2F;</a><p>Layer 4 – Deployments - Connect your CI to push container images to a public&#x2F;private registry. - Edka updates deployments automatically (with semantic versioning rules), supports instant rollbacks, autoscaling, persistent volumes, secrets&#x2F;env imports, and quick public exposure. Quick demo: <a href="https:&#x2F;&#x2F;edka.io&#x2F;deployments&#x2F;" rel="nofollow">https:&#x2F;&#x2F;edka.io&#x2F;deployments&#x2F;</a><p>Tech stack: TypeScript, React + Tailwind CSS, PostgreSQL, Redis, BullMQ, Vault + AWS KMS to encrypted sensitive data.<p>The platform is still in beta and I’m building it in my spare time, so there are some rough edges, but I’d love feedback from anyone running Kubernetes on Hetzner, exploring alternatives to EKS&#x2F;GKE&#x2F;AKS or looking to automate their infrastructure with Kubernetes.<p>More details: <a href="https:&#x2F;&#x2F;edka.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;edka.io&#x2F;</a><p>Thank you!

[Other] Show HN: Ldns.com – fast DNS lookups from the URL bar I built LDNS because I&#x27;m constantly curious about domain names - who owns them, which nameservers they use, how they&#x27;re configured, and what their DNS records reveal. I wanted a fast, easy way to investigate domains right from my browser without juggling multiple tools.<p>LDNS runs entirely client-side using Cloudflare&#x27;s DNS over HTTPS. Just type a domain and instantly see:<p>All DNS records with clickable filtering RDAP&#x2F;WHOIS data with registrar info and expiration dates Email security configuration (SPF, DMARC, MTA-STS, BIMI) Export options (JSON, CSV, BIND zones, PDF reports)<p>Try it at ldns.com - just append any domain like ldns.com&#x2F;example.com to start investigating.<p>Built with SvelteKit and deployed on Cloudflare Pages for that instant-load experience we all love.<p>Comments, feedback, and feature requests welcome!

[Other] Show HN: PgHook – Docker image that streams PostgreSQL row changes to webhooks I needed real-time updates in a web UI whenever PostgreSQL table rows change, so I built PgHook. It&#x27;s a 23 MB Docker image (10.1 MB compressed), .NET9 AOT-compiled, that streams logical replication events and sends them to a configurable webhook.<p>In my setup, the webhook converts events to SignalR messages that push updates to the UI.<p>I know about Debezium but I needed something minimal, and I like playing with csharp.

[Other] Show HN: MCP Security Suite Hi HN!<p>We kept seeing devs get pwned through MCP tools in ways that security scanners completely miss. So we built an open-source analyzer to catch these attacks. Our first OSS by Mighty team.<p>The problem: At Defcon, we saw MCP exploits with 100% success rate against Claude and Llama. Three attack patterns:<p>Hidden Unicode in &quot;error messages&quot; - Paste a colleague&#x27;s error into Claude, your SSH keys get exfiltrated Trusted tool updates - That database tool you&#x27;ve used for months? Last week&#x27;s update added credential theft Tool redefinition - Malicious tool redefines &quot;deploy to prod&quot; to run attacker&#x27;s script<p>Traditional scanners (CodeQL, SonarQube) catch &lt;15% of these. They&#x27;re looking for SQLi, not prompt injections hidden in tool descriptions.<p>What we built: git clone <a href="https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security</a><p>python analyzers&#x2F;comprehensive_mcp_analyzer.py &#x2F;path&#x2F;to&#x2F;your&#x2F;mcp&#x2F;tool<p>Scans for prompt injection, credential exfil, suspicious updates, tool shadowing. Runtime wrapper adds &lt;10ms overhead. Fully local, no telemetry.<p>Why this matters: 43% of MCP tools have command injection vulns. GitHub&#x27;s own MCP server was exploitable. We found Fortune 500s running database-connected MCP tools that hadn&#x27;t been audited since installation. We went from paranoid code review to &quot;AI said it works&quot; in 18 months. The magic is real, but so are the vulnerabilities.<p>Demo: <a href="https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;e830c56d39254a788776358c5b03fdc3" rel="nofollow">https:&#x2F;&#x2F;www.loom.com&#x2F;share&#x2F;e830c56d39254a788776358c5b03fdc3</a><p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;NineSunsInc&#x2F;mighty-security</a><p>Would love feedback - what MCP security issues have you seen?

[Other] Show HN: Modelence – Supabase for MongoDB Hi all, Aram and Eduard here - authors of Modelence (<a href="https:&#x2F;&#x2F;github.com&#x2F;modelence&#x2F;modelence" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;modelence&#x2F;modelence</a>), an all-in-one backend platform for teams that love TypeScript + MongoDB. Think Supabase, but for MongoDB: auth, cron jobs, email, monitoring, without glue code before you can ship.<p>As Karpathy (and many of us) noted, getting from prototype to production is mostly painful integration work. The pieces exist, but stitching them together reliably is the hard part: <a href="https:&#x2F;&#x2F;x.com&#x2F;karpathy&#x2F;status&#x2F;1905051558783418370" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;karpathy&#x2F;status&#x2F;1905051558783418370</a>. YC AI Startup School talk about this - <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?feature=shared&amp;t=1940&amp;v=LCEmiRjPEtQ" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?feature=shared&amp;t=1940&amp;v=LCEmiR...</a><p>We intend to fill those gaps! What you get out of the box:<p>- Authentication &#x2F; user management<p>- Database<p>- Email integration (3rd party, but things like user verification emails work out of the box)<p>- AI integration<p>- Cron jobs<p>- Monitoring &#x2F; Telemetry<p>- Configs &amp; secrets<p>- Analytics (coming soon)<p>- File uploads (coming soon)<p>How it runs: A Node.js backend with MongoDB. It&#x27;s frontend-agnostic, so you can use our minimal Vite + React starter or drop Modelence behind an existing Next.js (or any) frontend.<p>We&#x27;re also building a managed cloud, similar to what Vercel is for Next.js, except Modelence focuses on the backend instead of the frontend (Vercel is great for content sites like landing pages, blogs, etc, but things like persistent connections and complex backend logic outgrow it quickly). You can find a quick demo here: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=S4f22FyPpI8" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=S4f22FyPpI8</a><p>We&#x27;re looking for early users (especially TS teams on MongoDB). Tell us what&#x27;s missing, what&#x27;s confusing, and what you&#x27;d want before trusting this in prod. Happy to answer anything!

[CLI Tool] Show HN: OWhisper – Ollama for realtime speech-to-text Hello everyone. This is Yujong from the Hyprnote team (<a href="https:&#x2F;&#x2F;github.com&#x2F;fastrepl&#x2F;hyprnote" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;fastrepl&#x2F;hyprnote</a>).<p>We built OWhisper for 2 reasons: (Also outlined in <a href="https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;what-is-this" rel="nofollow">https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;what-is-this</a>)<p>(1). While working with on-device, realtime speech-to-text, we found there isn&#x27;t tooling that exists to download &#x2F; run the model in a practical way.<p>(2). Also, we got frequent requests to provide a way to plug in custom STT endpoints to the Hyprnote desktop app, just like doing it with OpenAI-compatible LLM endpoints.<p>The (2) part is still kind of WIP, but we spent some time writing docs so you&#x27;ll get a good idea of what it will look like if you skim through them.<p>For (1) - You can try it now. (<a href="https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;cli&#x2F;get-started" rel="nofollow">https:&#x2F;&#x2F;docs.hyprnote.com&#x2F;owhisper&#x2F;cli&#x2F;get-started</a>)<p><pre><code> bash brew tap fastrepl&#x2F;hyprnote &amp;&amp; brew install owhisper owhisper pull whisper-cpp-base-q8-en owhisper run whisper-cpp-base-q8-en </code></pre> If you&#x27;re tired of Whisper, we also support Moonshine :) Give it a shot (owhisper pull moonshine-onnx-base-q8)<p>We&#x27;re here and looking forward to your comments!
