Show HN: Kuack – Run Kubernetes jobs in visitor browsers
Show HN (score: 5)Description
Kuack is a Virtual Kubelet provider that schedules Kubernetes workloads to browser tabs. Visitors' browsers connect, report capacity, and become ephemeral workers. It looks like a regular Kubernetes node - same kubectl commands, same OCI images, same workflows. The difference is that pods execute in browsers instead of servers. With multi-platform OCI images, Kubernetes can fall back to regular nodes if no agents are available.
It's designed for short-lived, stateless, CPU-heavy jobs: load testing from real networks, local data preprocessing, edge computing scenarios, machine learning tasks, etc.
Not a replacement for your cluster - just an extra option for workloads that benefit from browser execution.

Show HN: AI video generator that outputs React instead of video files
Show HN: AI video generator that outputs React instead of video files Hey HN! This is Mayank from Outscal with a new update. Our website is now live. Quick context: we built a tool that generates animated videos from text scripts. The twist: instead of rendering pixels, it outputs React/TSX components that render as the video.<p>Try it: <a href="https://ai.outscal.com/" rel="nofollow">https://ai.outscal.com/</a> Sample video: <a href="https://outscal.com/v2/video/ai-constraints-m7p3_v1/12-01-26-18-47-41" rel="nofollow">https://outscal.com/v2/video/ai-constraints-m7p3_v1/12-01-26...</a><p>You pick a style (pencil sketch or neon), enter a script (up to 2000 chars), and it runs: scene direction → ElevenLabs audio → SVG assets → Scene Design → React components → deployed video.<p>What we learned building this:<p>We built the first version on Claude Code. Even with a human triggering commands, agents kept going off-script — they had file tools and would wander off reading random files, exploring tangents, producing inconsistent output.<p>The fix was counterintuitive: fewer tools, not more guardrails. We stripped each agent to only what it needed and pre-fed context instead of letting agents fetch it themselves.<p>Quality improved immediately.<p>We wouldn't launch the web version until this was solid. Moved to Claude Agent SDK, kept the same constraints, now fully automated.<p>Happy to discuss the agent architecture, why React-as-video, or anything else.
Show HN: SubTrack – A SaaS tracker for devs that finds unused tools
Show HN: SubTrack – A SaaS tracker for devs that finds unused tools Hi HN,<p>I built SubTrack to help teams find unused SaaS tools and cloud resources before they silently eat into budgets.<p>The motivation came from seeing how hard it is to answer simple questions: – Which SaaS tools are actually used? – Which cloud resources are idle? – What will our end-of-month spend look like?<p>SubTrack connects to tools like AWS, GitHub, Vercel, and others to surface unused resources and cost signals from one place. Recently I added multi-account support, currency localization, and optional AI-based insights to help interpret usage patterns.<p>This is an early-stage project and I’m actively iterating. I’d really appreciate feedback—especially from people managing cloud or SaaS sprawl.
