Show HN: I put HN discussions next to the article where it belongs It it always bugged me when I read or share an article, the discussion lives separately from the article. I imagined being able to add Google-Docs or Notion style comments on any website. We save a snapshot of the website and allow adding discussions that live side-by-side and directly reference parts of the article. HN articles are automatically indexed in https://cooo.link/hackernews and you can add any website, PDFs on https://cooo.link/ Built with SvelteKit, SingleFile(for …
Show HN: Agent Action Protocol (AAP) – MCP got us started, but is insufficient https://ift.tt/JtuWnxA
Show HN: Agent Action Protocol (AAP) – MCP got us started, but is insufficient Background: I've been working on agentic guardrails because agents act in expensive/terrible ways and something needs to be able to say "Maybe don't do that" to the agents, but guardrails are almost impossible to enforce with the current way things are built. Context: We keep running into so many problems/limitations today with MCP. It was created so that agents have context on how to act in the world, it wasn't designed to become THE standard …
Show HN: Demucs music stem separator rewritten in Rust – runs in the browser https://ift.tt/jVnxb96
Show HN: Demucs music stem separator rewritten in Rust – runs in the browser Hi HN! I reimplemented HTDemucs v4 (Meta's music source separation model) in Rust, using Burn. It splits any song into individual stems — drums, bass, vocals, guitar, piano — with no Python runtime or server involved. Try it now: https://nikhilunni.github.io/demucs-rs/ (needs a WebGPU-capable browser — Chrome/Edge work best) GitHub: https://ift.tt/0qVo8Xj It runs three ways: - In the browser — the full ML inference pipeline compiles to WASM and runs on your GPU vi…

Show HN: CrowPay – add x402 in a few lines, let AI agents pay per request Hey HN – I've been building in the agent payments space for a while and the biggest bottleneck I see isn't the protocol (x402 is great) — it's that most API providers have no idea how to actually integrate it. The docs exist, the middleware exists, but going from "I have a REST API" to "agents can discover and pay for my endpoints" still takes way more work than it should. CrowPay fixes that. We integrate x402 payment headers into your exi…

Show HN: Deploybase – Compare GPU and LLM pricing across all major providers https://ift.tt/aYntOxc
Show HN: Deploybase – Compare GPU and LLM pricing across all major providers I built a dashboard for near real-time GPU and LLM pricing across cloud and inference providers. You can view performance stats and pricing history, compare side by side, and bookmark to track any changes. Also covers MLOps tools. Would appreciate any feedback. https://deploybase.ai https://deploybase.ai March 1, 2026 at 11:32PM
Show HN: Mrkd – A native macOS Markdown viewer with iTerm2/VSCode theme import https://ift.tt/zbnasie
Show HN: Mrkd – A native macOS Markdown viewer with iTerm2/VSCode theme import Using Opus 4.6 I built a markdown viewer for macOS that uses zero web technology. No Electron, no WebView — markdown is parsed with cmark-gfm and rendered directly to NSAttributedString via TextKit 2. The result is native text selection, native accessibility, and a ~1MB binary that launches pretty much instantly. It supports GFM tables, task lists, syntax-highlighted code blocks, and inline images. You get a built-in themes (Solarized, Dracula, GitHub, Monokai) plus…
