[Other] Show HN: Sourcerer – MCP for semantic code search that reduces token waste I built this because I got tired of watching Claude Code read through massive files just to find a few functions. Sourcerer lets AI agents search code semantically and grab exactly the code chunks they need instead of burning tokens on whole files.<p>It uses tree-sitter to parse your codebase and creates a searchable index. So instead of &quot;read auth.py (538 lines)&quot;, an agent can search for &quot;user authentication logic&quot; and get back just the relevant functions.<p>Demo: <a href="https:&#x2F;&#x2F;asciinema.org&#x2F;a&#x2F;736638" rel="nofollow">https:&#x2F;&#x2F;asciinema.org&#x2F;a&#x2F;736638</a><p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;st3v3nmw&#x2F;sourcerer-mcp" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;st3v3nmw&#x2F;sourcerer-mcp</a>

[CLI Tool] Show HN: Datacmd – Terminal-native dashboards from CSV/API in one command Hi HN,<p>I built Datacmd to eliminate bloated dashboards and browser UIs. It turns any CSV, JSON, API feed into live, terminal-native dashboards with one command. Fast. Minimal. Developer-centric. AND IT&#x27;S OPEN SOURCE <a href="https:&#x2F;&#x2F;github.com&#x2F;VincenzoManto&#x2F;datacmd" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;VincenzoManto&#x2F;datacmd</a><p>What it does:<p>* Generates dynamic dashboards in the terminal: tables, gauges, pie charts, line charts, radars, text boxes * Layout auto-generated or configurable via YAML * Supports CSV, JSON, REST APIs, live system metrics (CPU, memory, disk)<p>Why this matters:<p>* No GUI. Instant visuals where developers live * Zero setup. Download binary or use &quot;go run&quot;, and dashboards appear * Great for sysadmins, devs, ops, data hackers working in terminal-first workflows<p>What I learned building it: Automating a clean layout via algorithm beats manual dashboard design for fast insights. Generating widgets in terminal forces clarity - no fluff, just signal.<p>Looking for feedback on:<p>* Performance with massive datasets (&gt;100k rows) * UX: readability, layout transitions, color themes * Widget ideas: real-time alerts, sparkline ring charts, CLI-friendly drill-downs<p>Live on GitHub. Let me know if you want a downloadable binary or CI build link. Open to contributions, bug reports, wild dashboard ideas.

[DevOps] Show HN: Kanto.ai – The soc2 ready infra agent Hey HN,<p>I am launching kanto.ai and looking for early beta users.<p>This came out of my own experience. I was responsible for building and maintaining SOC-2 compliance for a Kubernetes application in GCP. The GCP Cloud Foundation Blueprints are a solid starting point, but they are difficult to set up and even harder to keep updated as requirements, policies, and cloud services evolve. Many aspects required for Soc2 are also not provided out of the box.<p>kanto.ai is a GitHub bot that bootstraps an enterprise-grade, multi-repo, git-ops first GCP deployment and automates ongoing maintenance. It watches GitHub issues and generates Terraform pull requests with best practices built in. Under the hood it uses GCP’s Cloud Foundation Toolkit modules for projects, networking, org policies, IAM, and more. The goal is to keep infrastructure SOC-2 ready out of the box.<p>Right now it is early with a landing page and working prototype. I would love feedback from anyone who has dealt with SOC-2, Kubernetes, or the Foundation Blueprints in GCP.<p>Does this solve a real pain you have felt? What blockers did you run into with SOC-2 in GCP? If you used the GCP Cloud Foundation Toolkit, what worked and what did not?<p>Thanks.

[Other] Show HN: FFmpeg Pages – because I was tired of fighting FFmpeg You ever just want to shrink a video… and suddenly you’re buried in flags, half-broken StackOverflow answers, and 10 tabs open just to figure out one command?<p>That’s been me. Every. Single. Time.<p>So I built FFmpeg Pages — a dead-simple collection of the commands I kept searching for. No fluff, no digging, just the stuff that actually works.

[Other] Show HN: VR.dev – a developer network for VR/XR/AR devs I built vr.dev as a lightweight network for people in the VR, XR, and AR development community to showcase demos, promote themselves, and find collaborators. It’s early, but usable for portfolios and discovery.<p>Example profile: <a href="https:&#x2F;&#x2F;vr.dev&#x2F;erik" rel="nofollow">https:&#x2F;&#x2F;vr.dev&#x2F;erik</a><p>What’s live now:<p>- Profiles with vr.dev&#x2F;[username] URLs<p>- Showcase a .glTF file<p>- Resume&#x2F;experience with industry-specific signals<p>What’s coming:<p>- Options for more showcases and supported asset types<p>- Advanced searching on experience and skills<p>- Closer integration with GitHub<p>- Better discovery<p>I’d love feedback on what I can add to make this more useful for you!<p>I’ll be hanging out here all day but feel free to reach out — hn@vr.dev

[Other] Show HN: Sosumi.ai – Convert Apple Developer docs to AI-readable Markdown I got tired of Claude hallucinating Swift APIs. It does a good job at Python and TypeScript, but ask it about SwiftUI and it&#x27;s basically guessing.<p>The problem? Apple&#x27;s docs are JavaScript-rendered, so when you paste URLs into AI tools, they just see a blank page. Copy-pasting works but... c&#x27;mon.<p>So I built something that converts Apple Developer docs to clean markdown. Just swap developer.apple.com with sosumi.ai in any Apple docs URL and you get AI-readable content.<p>For example:<p>- Before: <a href="https:&#x2F;&#x2F;developer.apple.com&#x2F;documentation&#x2F;swift&#x2F;double" rel="nofollow">https:&#x2F;&#x2F;developer.apple.com&#x2F;documentation&#x2F;swift&#x2F;double</a><p>- After: <a href="https:&#x2F;&#x2F;sosumi.ai&#x2F;documentation&#x2F;swift&#x2F;double" rel="nofollow">https:&#x2F;&#x2F;sosumi.ai&#x2F;documentation&#x2F;swift&#x2F;double</a><p>The site itself is a small Hono app running on Cloudflare Workers. Apple&#x27;s docs are actually available as structured data, but Apple doesn&#x27;t make it obvious how to get it. So what this does is map the URLs, fetch the original JSON, and render as Markdown.<p>It also provides an MCP interface that includes a tool to search the Apple developer website, which is helpful.<p>Anyway, please give this a try and let me know what you think!

[Other] Show HN: Docustore – Vectorized Technical Documentations docustore&#x27;s aim is to provide up-to-date, off-the shelf and plug-and-play context for LLMs from a curated list of frameworks&#x2F;sdks. It has a 4 step pipeline: scrape the documentation - clean it - vectorize it - package it. My vision is to host it somewhere and develop an API&#x2F;MCP around it so it will be development-environment agnostic.
