[Other] Show HN: Craftplan – I built my wife a production management tool for her bakery My wife was planning to open a micro-bakery. We looked at production management software and it was all either expensive or way too generic. The actual workflows for a small-batch manufacturer aren&#x27;t that complex, so I built one and open-sourced it.<p>Craftplan handles recipes (versioned BOMs with cost rollups), inventory (lot traceability, demand forecasting, allergen tracking), orders, production batch planning, and purchasing. Built with Elixir, Ash Framework, Phoenix LiveView, and PostgreSQL.<p>Live demo: <a href="https:&#x2F;&#x2F;craftplan.fly.dev" rel="nofollow">https:&#x2F;&#x2F;craftplan.fly.dev</a> (test@test.com &#x2F; Aa123123123123)<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;puemos&#x2F;craftplan" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;puemos&#x2F;craftplan</a>

[API/SDK] Show HN: Voiden – an offline, Git-native API tool built around Markdown Hi HN,<p>We have open-sourced Voiden.<p>Most API tools are built like platforms. They are heavy because they optimize for accounts, sync, and abstraction - not for simple, local API work.<p>Voiden treats API tooling as files.<p>It’s an offline-first, Git-native API tool built on Markdown, where specs, tests, and docs live together as executable Markdown in your repo. Git is the source of truth.<p>No cloud. No syncing. No accounts. No telemetry.Just Markdown, Git, hotkeys, and your damn specs.<p>Voiden is extensible via plugins (including gRPC and WSS).<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;VoidenHQ&#x2F;voiden" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;VoidenHQ&#x2F;voiden</a><p>Download Voiden here : <a href="https:&#x2F;&#x2F;voiden.md&#x2F;download" rel="nofollow">https:&#x2F;&#x2F;voiden.md&#x2F;download</a><p>We&#x27;d love feedback from folks tired of overcomplicated and bloated API tooling !

[Other] Show HN: Zuckerman – minimalist personal AI agent that self-edits its own code Hi HN,<p>I&#x27;m building Zuckerman: a personal AI agent that starts ultra-minimal and can improve itself in real time by editing its own files (code + configuration). Agents can also share useful discoveries and improvements with each other.<p>Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;zuckermanai&#x2F;zuckerman" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;zuckermanai&#x2F;zuckerman</a><p>The motivation is to build something dead-simple and approachable, in contrast to projects like OpenClaw, which is extremely powerful but has grown complex: heavier setup, a large codebase, skill ecosystems, and ongoing security discussions.<p>Zuckerman flips that:<p>1. Starts with almost nothing (core essentials only).<p>2. Behavior&#x2F;tools&#x2F;prompts live in plain text files.<p>3. The agent can rewrite its own configuration and code.<p>4. Changes hot-reload instantly (save -&gt; reload).<p>5. Agents can share improvements with others.<p>6. Multi-channel support (Discord&#x2F;Slack&#x2F;Telegram&#x2F;web&#x2F;voice, etc).<p>Security note: self-edit access is obviously high-risk by design, but basic controls are built in (policy sandboxing, auth, secret management).<p>Tech stack: TypeScript, Electron desktop app + WebSocket gateway, pnpm + Vite&#x2F;Turbo.<p>Quickstart is literally:<p><pre><code> pnpm install &amp;&amp; pnpm run dev </code></pre> It&#x27;s very early&#x2F;WIP, but the self-editing loop already works in basic scenarios and is surprisingly addictive to play with.<p>Would love feedback from folks who have built agent systems or thought about safe self-modification.

[API/SDK] Describe your API. Get a live URL. Instantly. Describe your API in plain English. Get a live URL instantly. Build your frontend without waiting for the backend.Stop waiting for backend teams. VaporMock uses AI to generate realistic mock APIs from plain English descriptions. Just type "I need a list of 50 users with Indian names" and get a deployed, ready-to-use API endpoint in seconds. Perfect for frontend devs and prototyping.

[DevOps] AI Orchestration Layer for Coding Agents 🖥️ Turn your terminal into an AI command center. Kagan is a keyboard-first Kanban TUI that orchestrates AI agents (Claude Code, OpenCode) to complete tickets autonomously or collaboratively. Two modes: ⚡ PAIR — Real-time tmux sessions with AI 🤖 AUTO — Background agents working in parallel Describe features in natural language → Kagan breaks them into actionable tickets. Each task runs in isolated git worktrees, keeping your main branch safe. Code review ensures human oversight before merge.

[Other] Sync your design tokens between Figma and code Bridge the gap between code and design. Designed to work with the Styleframe - the engine for writing type-safe, composable, and future-proof CSS in TypeScript. Styleframe lets you import and export design tokens using the industry-standard W3C DTCG format, keeping your Figma variables perfectly synchronized with your codebase. Compatible with Style Dictionary, Tokens Studio, and other DTCG-compatible tools. No subscriptions. No seat limits. Your design system, your rules.

[CLI Tool] Allows Agentic IDEs like Antigravity to build n8n workflows MCP tool to make building possible for Antigravity, Cursor, Windsurf, Claude. We solve all the pain points everyone faced, node corruptions, configurations, LLM hallucinations, proper main level node connections and sub node connections. There are 45+ MCP commands and around 64 CLI commands enabling both ways to build n8n workflows via guardrail toolsets developed. Also agents in any IDE will be able to use the latest version nodes taking into account your current n8n version.

[DevOps] Show HN: Minimal – Open-Source Community driven Hardened Container Images I would like to share Minimal - Its a open source collection of hardened container images build using Apko, Melange and Wolfi packages. The images are build daily, checked for updates and resolved as soon as fix is available in upstream source and Wolfi package. It utilizes the power of available open source solutions and contains commercially available images for free. Minimal demonstrates that it is possible to build and maintain hardened container images by ourselves. Minimal will add more images support, and goal is to be community driven to add images as required and fully customizable.

[Other] Show HN: Quorum-free replicated state machine built atop S3 Hi HN,<p>I’m sharing the alpha release of S2C, a state machine replication system built atop S3.<p>The goal is to enable a distributed application to maintain consistent state without needing a quorum of nodes for availability or consistency.<p>The idea came from a side project that was using S3 and where I needed strongly consistent distributed state but wanted to avoid adding a separate consensus dependency. I initially tried to use S3 directly for coordination, but it became messy. Eventually, I realized I need a replicated state machine with a deterministic log, and then it ended up as a standalone project.<p>To mitigate S3&#x27;s latency and API costs, it uses time- and size-based batching by default.<p>S2C supports: - Linearizable reads and writes (with single node) - Exactly-once command semantics (for nodes with stable identities) - Dynamic node joins and cold-start recovery from zero nodes - Split-brain safety without clocks or leases - Snapshotting, log truncation, etc.<p>Of course, it trades latency and S3 operation costs for operational simplicity - not meant to replace high-throughput Raft rings. And clearly, only usable in architectures that already use S3 (or compatible with similar guarantees).<p>It has passed chaos&#x2F;fault-injection tests so far (crashes, partitions, leader kills); formal verification planned.<p>It’s still alpha, but I’d love for people to try it, experiment, and provide feedback.<p>If you’re curious, the code, and an extensive deep dive guide are here: [<a href="https:&#x2F;&#x2F;github.com&#x2F;io-s2c&#x2F;s2c" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;io-s2c&#x2F;s2c</a>]
