[DevOps] Show HN: KubeForge – A GUI for Kubernetes YAMLs Hey HN,<p>I&#x27;m Brandon, a solo dev, and I built KubeForge - a visual editor for Kubernetes deployments that helps you build and validate YAML configs.<p>Origin Story: Over the past couple weeks, I got fed up manually writing Kubernetes YAMLs, especially when working with nested structures like containers, env, and volumeMounts. Even small typos or misaligned fields added lost time to broken deploys.<p>So I started hacking together a tool to visualize the structure of Kubernetes objects based on the OpenAPI schema. That prototype quickly turned into a full manifest builder.<p>What KubeForge does:<p>- Pulls the latest Kubernetes OpenAPI schema (auto-updated daily)<p>- Generates field-level forms with type safety, required fields, and smart defaults<p>- Lets you visually build manifests like a flow editor<p>- Outputs clean, deploy-ready YAML, with multi-object exports<p>Personally, I wanted a tool that:<p>- Validates fields as I build, not after deployment<p>- Surfaces nested fields, tooltips, and types without switching tabs<p>- Lets me export or share real YAMLs easily<p>Try it out:<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;kubenote&#x2F;KubeForge">https:&#x2F;&#x2F;github.com&#x2F;kubenote&#x2F;KubeForge</a><p>Live demo: <a href="https:&#x2F;&#x2F;demo.kubefor.ge" rel="nofollow">https:&#x2F;&#x2F;demo.kubefor.ge</a><p>Website: <a href="https:&#x2F;&#x2F;kubefor.ge" rel="nofollow">https:&#x2F;&#x2F;kubefor.ge</a><p>It’s free and open source.

[Other] Show HN: Zero Waste Cloud – Finds 20-40% savings in AWS/GCP bills and CO2 impact Hey HN! I&#x27;m Mike, based in Stockholm&#x2F;Sweden and I&#x27;m the founder of Zero Waste Cloud (<a href="https:&#x2F;&#x2F;zerowastecloud.io" rel="nofollow">https:&#x2F;&#x2F;zerowastecloud.io</a>) - a tool that scans AWS and GCP infrastructure to find cost optimization opportunities while calculating the environmental impact. Almost all businesses can save 20-40% of their cloud costs using this tool (sources at bottom)<p>TLDR: Sign up -&gt; Connect your AWS&#x2F;GCP -&gt; Scan -&gt; Save 20-40% of your cloud spend.<p>My backstory: I&#x27;ve been a CISO and in IT management for a long time and always been frustrated by how much waste I&#x27;d find in every environment - idle EC2 instances running 24&#x2F;7, oversized RDS databases, forgotten storage volumes, test resources that never gets removed. What also bothered me was that nobody was tracking the environmental cost of this waste. Every unused resource burns electricity and contributes to carbon emissions unnecessarily.<p>What it does:<p>- Scans AWS accounts using IAM roles or access keys, GCP projects using service account keys<p>- Identifies specific optimization opportunities: unused EC2&#x2F;Compute Engine instances, oversized databases, unattached storage, missed reservation opportunities and much more<p>- Calculates financial savings AND CO₂ reduction for each recommendation using region-specific grid emission factors<p>- Multi-account&#x2F;project support<p>- Generates detailed reports with prioritized recommendations<p>Technical details: Built with React&#x2F;TypeScript frontend, Supabase backend. Uses AWS SDK for EC2, RDS, Cost Explorer APIs and GCP&#x27;s Compute Engine, Cloud SQL, and Cloud Billing APIs. Carbon calculations combine cloud provider PUE data with regional electricity grid emission factors from government sources.<p>Try it out: The onboarding from creation to your first scan being run is only ~30 seconds. The scanning process is fully automated and typically completes in 5-30 minutes depending on account size of course.<p>I would genuinely love to get your feedback on it, just came out of beta a few days ago so if there&#x27;s any bugs around please do let me know =)<p>If you&#x27;re on Linkedin let&#x27;s connect: <a href="https:&#x2F;&#x2F;www.linkedin.com&#x2F;in&#x2F;almstedt&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.linkedin.com&#x2F;in&#x2F;almstedt&#x2F;</a><p>Sources:<p>&quot;companies estimate that 21-50% of their cloud expenditure is wasted&quot; (<a href="https:&#x2F;&#x2F;www.techmonitor.ai&#x2F;hardware&#x2F;cloud&#x2F;cloud-waste-hits-billions-as-78-of-firms-report-significant-expenditure-losses" rel="nofollow">https:&#x2F;&#x2F;www.techmonitor.ai&#x2F;hardware&#x2F;cloud&#x2F;cloud-waste-hits-b...</a>)<p>&quot;45% of cloud customer’s expenditures are spent on resources they will never use&quot; (<a href="https:&#x2F;&#x2F;www.sciencedirect.com&#x2F;science&#x2F;article&#x2F;abs&#x2F;pii&#x2F;S2210537922000476" rel="nofollow">https:&#x2F;&#x2F;www.sciencedirect.com&#x2F;science&#x2F;article&#x2F;abs&#x2F;pii&#x2F;S22105...</a>)<p>&quot;21% of enterprise cloud infrastructure spend &#x2F;.. &#x2F; in 2025*—is wasted on underutilized resources (<a href="https:&#x2F;&#x2F;www.prnewswire.com&#x2F;news-releases&#x2F;44-5-billion-in-infrastructure-cloud-waste-projected-for-2025-due-to-finops-and-developer-disconnect-finds-finops-in-focus-report-from-harness-302385580.html" rel="nofollow">https:&#x2F;&#x2F;www.prnewswire.com&#x2F;news-releases&#x2F;44-5-billion-in-inf...</a>)

Inspired by the aesthetics of raw markdown, I wanted to create a beautiful blog like <a href="https:&#x2F;&#x2F;github.com&#x2F;panr&#x2F;hugo-theme-terminal">https:&#x2F;&#x2F;github.com&#x2F;panr&#x2F;hugo-theme-terminal</a> but supercharged with a modern redesign and the incredible features of Astro.<p>Features:<p><pre><code> - Simple configuration file - Multiple theme modes (single, light&#x2F;dark&#x2F;auto, select) - Giscus comments - RSS feed - SEO best practices + social card generation - Markdown extensions (TOC, admonitions, reading time, etc)</code></pre>

[API/SDK] Show HN: Mcp-use – Connect any LLM to any MCP Hey Pietro and Luigi here, we are the authors of mcp-use (<a href="https:&#x2F;&#x2F;github.com&#x2F;mcp-use&#x2F;mcp-use">https:&#x2F;&#x2F;github.com&#x2F;mcp-use&#x2F;mcp-use</a>).<p>When the first MCP servers came out we were very excited about the technology, but as soon as we wanted to get our hands dirty, we found out that MCP could be used only through Claude Desktop or Cursor. As engineers, we did not like that. MCP seemed like something you wanted to use to build products and applications yourself, not something to hide behind a closed source application.<p>So we approached the SDK but were pretty dissatisfied with the developer experience (double async loops, lots of boilerplate). We decided to write mcp-use to make our lives easier.<p>mcp-use lets you connect any LLM to any MCP server in just 6 lines of code. We provide a high level abstraction over the official MCP SDK that makes your life easier and supports all the functionalities of the protocol.<p>Demo video here: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=nL_B6LZAsp4" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=nL_B6LZAsp4</a>.<p>The key abstractions we provide are called MCPClient and MCPAgent.<p>MCPClient takes in a set of server configurations, automatically detects the transport type and creates a background task which handles the stream from&#x2F;to the server.<p>MCPAgent is a combination of the MCPClient, an LLM, and a custom system prompt. It consumes the MCP client by transforming the tools, resources and prompts into model agnostic tools that can be called by the LLM.<p>The library also contains some cool utilities:<p>- secure sandboxed execution of MCP servers (we know the protocol doesn&#x27;t shine for security)<p>- meta-tools that allow the agent to search over available servers and tools (to avoid context flooding) and connect dynamically to the server it needs (you could create the omnipotent agent with this).<p>Some cool things we did with this: - write an agent that can use a browser and create&#x2F;read linear tickets updated with latest information on the internet<p>- write an agent that has access to the metrics of our company to automatically create weekly reports.<p>- I connected an agent to an IKEA curtain I hacked an MCP on to adapt the lighting of my room from images of the lighting situation.<p>- recreated am open source claude code like CLI, with full MCP capability but with custom models and BYOK (<a href="https:&#x2F;&#x2F;github.com&#x2F;mcp-use&#x2F;mcp-use-cli">https:&#x2F;&#x2F;github.com&#x2F;mcp-use&#x2F;mcp-use-cli</a>).<p>We recently crossed 100,000 download and we are used by many organizations, including NASA!<p>We’d love to hear what you think of it, most importantly how we can improve it! We are happy to answer any questions and look forward to your comments.

[API/SDK] Show HN: AgentMail – Email infra for AI agents Hey HN, we&#x27;re Haakam, Michael, and Adi. We&#x27;re building AgentMail (<a href="https:&#x2F;&#x2F;agentmail.to&#x2F;">https:&#x2F;&#x2F;agentmail.to&#x2F;</a>), an API to give AI agents their own email inboxes. We’re not talking about AI for your email, this is email for your AI.<p>We started building email agents because they can converse with users in their inboxes, automate email-based workflows, and authenticate with third-party applications. Given these unique capabilities, we think email will be a core interface for agents.<p>But we were building on top of Gmail, which was a struggle: poor API support, expensive subscriptions, rate limits, sending limits, GCP Pub&#x2F;Sub, OAuth, crappy keyword search, and an overall terrible developer experience.<p>Gmail and other providers didn’t work for us. So we decided to bite the bullet and build our own.<p>AgentMail is like Gmail, but API-first, with programmatic inbox creation, events over webhooks and websockets, simple API key auth, organization-wide semantic search, structured data extraction, and usage-based pricing that scales with emails sent&#x2F;received.<p>Here’s a demo of building an email agent: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;1V7BISeFUTM" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;1V7BISeFUTM</a>, and here’s a demo of a voice agent with its own email inbox: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;eG2fCsRK4RY" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;eG2fCsRK4RY</a><p>So far AgentMail has been deployed to use cases such as apps with dedicated inboxes for each user, voice agents that receive documents in real time, automated account provisioning and QA testing, cold outbound platforms with thousands of inboxes, automations for processing invoices, and agents that coordinate work with humans and other agents.<p>We would love to hear your thoughts and feedback. You can try our playground at <a href="https:&#x2F;&#x2F;chat.agentmail.to">https:&#x2F;&#x2F;chat.agentmail.to</a>

[Other] Show HN: Clauditate – Breathing exercises while Claude Code is thinking Hello HN!<p>I realized how often my mind wanders while waiting for Claude to finish &quot;thinking&quot;. So I built Clauditate, a lightweight meditation menubar app that helps you with some breathing exercises.<p>It uses Claude Code hooks and pops up with a breathing guide. I added some heuristics to make it less &quot;annoying&quot;, for example if you dismiss it twice within 30 mins, it won&#x27;t show up for another 2 hours. You can also tweak this behavior (and more) in the settings.<p>It&#x27;s early, but I&#x27;d love to hear your feedback!<p>Github: <a href="https:&#x2F;&#x2F;github.com&#x2F;ykumards&#x2F;clauditate">https:&#x2F;&#x2F;github.com&#x2F;ykumards&#x2F;clauditate</a>
