[IDE/Editor] Full project management inside VS Code, Cursor & Windsurf GitScrum Studio isn't just another task list extension. It's the entire project management platform embedded inside your IDE. Stop alt-tabbing to browser. Manage Kanban boards, sprints, chat with your team, track time, access files, discussions & wiki - all without leaving VS Code, Cursor, or Windsurf. Zero browser tabs. Zero context switching. Maximum focus. Built with Laravel backend, optimized for real-time performance.

[Other] Convert your Github Commits to clever X posts Automatically generate AI-enhanced social media posts from your GitHub commits. Build your developer brand with ready-to-share content that showcases your work.

[Other] CLI control to monitor and work with Claude Code remotely SessionCast lets you remotely access Claude Code running on your local machine from any device. Working with Claude Code on your home PC but need to step out? Traditional remote access requires VPN setup, SSH configuration, tmux, port forwarding... and after all that, non-ASCII characters still break. Run our lightweight agent on your PC, then access your Claude Code session from any web browser — phone, tablet, or another computer. No VPN. No SSH keys. No complex setup. Just works.

[Other] Free, shareable workflow graphs. Visualize your LLM workflows as interactive & shareable graphs. Point Codag at your codebase — it maps every LLM call, branch, and data flow. Click any node to jump to source. Live updates as you code. Self-hosted, open source.

[CLI Tool] Show HN: CLI tool to convert Markdown to rich HTML clipboard content At work I need to use Teams. It supports a few Markdown features, but the editing experience for long message isn&#x27;t smooth. So, I often write in nvim, preview it in the browser and then copy paste to Teams. This tool help me get rid of the review and copy step.<p>Build with Rust + Claude Code. Tested on Windows and Mac, should works on Ubuntu as well.<p>Caveats: it&#x27;s still up to the pasted app to handle the HTML clipboard content.

[Other] Show HN: Buquet – Durable queues and workflows using only S3 buquet (bucket queue) is a queue and workflow orchestration tool using only S3-compatible* object storage. S3 is the control plane making it much simpler than alternatives. This does come with tradeoffs (see docs), but I do believe there is a niche it can serve well.<p><a href="https:&#x2F;&#x2F;horv.co&#x2F;buquet.html" rel="nofollow">https:&#x2F;&#x2F;horv.co&#x2F;buquet.html</a> <a href="https:&#x2F;&#x2F;github.com&#x2F;h0rv&#x2F;buquet" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;h0rv&#x2F;buquet</a><p>* see <a href="https:&#x2F;&#x2F;github.com&#x2F;h0rv&#x2F;buquet&#x2F;blob&#x2F;main&#x2F;docs&#x2F;guides&#x2F;s3-compatibility.md" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;h0rv&#x2F;buquet&#x2F;blob&#x2F;main&#x2F;docs&#x2F;guides&#x2F;s3-comp...</a>

[DevOps] Show HN: Pygantry – Why ship a whole OS when you just need a Python environment? &quot;Hi Hacker News, I’ve always found Docker to be overkill for simple Python deployments. It&#x27;s heavy, complex for non-tech users, and often results in 500MB+ images for a 10KB script. That’s why I built Pygantry. It’s a minimalist &#x27;container&#x27; engine based on Python venv but made portable and relocatable. Key features: Lightweight: A full &#x27;shipped&#x27; app is usually &lt; 20MB. Zero-Config: No daemon, no root, no Dockerfile complexity. Portable: Build once, zip it, and run it anywhere with a Python interpreter. Founder friendly: Built-in licensing and stealth modes for those building a business. I built this to simplify my own VPS deployments. I&#x27;d love to get your feedback on the architecture and how you handle &#x27;Docker-fatigue&#x27; in your workflow.

[Other] Show HN: Mmdr – 1000x faster Mermaid rendering in pure Rust (no browser) I was building a Rust-based agentic coding TUI and needed to render Mermaid diagrams. Noticed the official mermaid-cli spawns a full browser instance (Puppeteer&#x2F;Chrome) just to render diagrams. Decided to fix this.<p>mmdr is a native Rust renderer. No browser, no Node.js.<p><pre><code> mermaid-cli: ~3000ms per diagram mmdr: ~3ms per diagram </code></pre> Supports 13 diagram types: flowchart, sequence, class, state, ER, pie, gantt, timeline, journey, mindmap, git graph, XY chart, and quadrant.

[API/SDK] Show HN: Teaching AI agents to write better GraphQL We’ve been seeing more and more developers use AI coding agents directly in their GraphQL workflows. The problem is the agents tend to fall back to generic or outdated GraphQL patterns.<p>After correcting the same issues over and over, we ended up packaging the GraphQL best practices and conventions we actually want agents to follow as reusable “Skills,” and open-sourced them here: <a href="https:&#x2F;&#x2F;github.com&#x2F;apollographql&#x2F;skills" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;apollographql&#x2F;skills</a><p>Install with `npx skills add apollographql&#x2F;skills` and the agent starts producing named operations with variables, `[Post!]!` list patterns, and more consistent client-side behavior without having to restate those rules in every prompt.<p>We’re hopeful agents can now write GraphQL the way we&#x27;d write it ourselves. Try out the repo and let us know what you think.

[API/SDK] Show HN: Webhook Skills – Agent skills for webhook providers and best practices I built a collection of webhook skills because AI coding agents are surprisingly bad at webhook integrations. The generated code looks reasonable until you run it, then signature verification fails, raw body handling is wrong, or the middleware order breaks everything.<p>PostHog&#x27;s research on LLM code generation (<a href="https:&#x2F;&#x2F;posthog.com&#x2F;blog&#x2F;correct-llm-code-generation" rel="nofollow">https:&#x2F;&#x2F;posthog.com&#x2F;blog&#x2F;correct-llm-code-generation</a>) found that agents produce more reliable code when referencing known-working examples rather than reconstructing from training data. That&#x27;s the approach here.<p>`webhook-skills` is a collection of provider-specific webhook implementations and best practices guides built on the Agent Skills spec (agentskills.io):<p><pre><code> - Runnable examples (currently Express, Next.js, FastAPI, with more frameworks coming) - Signature verification with provider-specific gotchas documented - Best-practice patterns: idempotency, error handling, retry logic - 11 providers at launch (Stripe, Shopify, GitHub, OpenAI, Clerk, Paddle, others), expanding based on my needs or requests. </code></pre> Example:<p><pre><code> # list skills npx skills add hookdeck&#x2F;webhook-skills --list # install skills npx skills add hookdeck&#x2F;webhook-skills --skill stripe-webhooks --skill webhook-handler-patterns </code></pre> Works with Claude Code, Cursor, Copilot. The examples are useful even without an agent: minimal, tested handlers you can copy directly.<p>PRs welcome for new providers and frameworks. I also built an AI-powered generator that automatically creates new provider skills. Point it at webhook docs, and it researches the signature scheme, generates verification code for each framework, writes tests, and opens a PR.

[Monitoring/Observability] API turnstile Sentinel is a developer-first security monitoring platform for SaaS and APIs. It detects bots, fraud, and abnormal behavior in real time, giving actionable alerts before damage happens. Lightweight, easy to integrate, and affordable — unlike bloated enterprise SIEMs, Sentinel keeps your apps safe without the complexity.

[IDE/Editor] Leverage coding agents to tackle complex tasks autonomously Xcode 26.3 introduces support for agentic coding, a new way in Xcode for developers to build apps using coding agents such as Anthropic’s Claude Agent and OpenAI’s Codex. With agentic coding, Xcode can work with greater autonomy toward a developer’s goals — from breaking down tasks to making decisions based on the project architecture and using built-in tools.

[Other] Sandbox claude code, codex, or any TUI on macOS Multitui is a macOS app factory that generates individual terminal apps for TUI programs, with optional sandbox. Create dedicated native apps for claude code, codex, gemini, lazygit, harlequin, or any TUI.
