Show HN: Duck – A Django-compatible framework with native HTTP/2 and Live HTMLhttps://news.ycombinator.com/item?id=47142493I’ve been working on Duck, a Python web framework designed to modernize the development experience without throwing away what we love about Django. For years, the standard path for real-time Python apps has been Django + Channels + Redis + daphne + Nginx. It works, but the overhead is immense. Duck aims to simplify this by making high-performance features "native" rather than "add-ons."Key Features:- Native HTTP/2 & HTTPS: No need for a reverse proxy just to get modern protocol support; Duck handles multiplexing out of the box.- Lively Components: Think Phoenix LiveView but for Python. Build reactive, stateful UIs that update over WebSockets without writing a single line of JavaScript.- Django Compatibility: You can keep your existing Django models and logic. Duck acts as a high-performance transport layer.- Zero-Dependency Automation: A built-in task system that replaces Cron/Celery for 90% of use cases.- Real-time Observability: A built-in terminal monitor (duck monitor) to watch youFeb 24, 2026 8:29 PM

Show HN: Glass Box: writing editor that exports a verifiable PDF of your processhttps://firl.nl/glass-boxWe built a local-first writing editor that records the composition process (keystrokes, paste events, AI interactions) and exports a PDF with annotation highlights + an AI usage appendix.The motivation: AI detectors are genuinely broken. Stanford research showed >60% false positive rates for non-native English writers on TOEFL essays. The "solution" from institutions has been to buy more detectors or make the policies so broad that either the student can do nothing if they are accused or the teacher can do nothing if the student does not make an admission.Instead of trying to detect AI use after the fact, we give students a way to record their process as they write. The exported PDF shows a professor exactly what was human-written, what was AI-assisted, and what was pasted from external sources.Tech stack: - NiceGUI (Python) for the editor - Quasar Q-Editor (contenteditable) with JS paste/ghost-completion hooks - Dual PDF engine: WeasyPrint (CSS rendering) with ReportLab fallback (pureFeb 24, 2026 3:20 PM

Show HN: Out Plane – A PaaS I built solo from Istanbul in 3 monthshttps://outplane.comHey HN,I posted Out Plane here last week. Wanted to share an update because I've been shipping a lot.I started this because deploying side projects was killing my motivation. Build something fun over a weekend, then waste two days on Dockerfiles, nginx, and SSL. So I built what I wanted — connect GitHub, push code, get a URL. Done.Since December I've added managed PostgreSQL, managed Redis with RedisInsight built in, Dockerfile auto-detection that pre-fills your config, real-time metrics, and scale to zero — no traffic means no bill. Per-second pricing, not hourly. Same Next.js + Postgres app costs me $2.40/mo vs $12–47 on other platforms.No CLI yet, docs need work, ~200 users. Just me, no team, no funding. But people are running real stuff on it.$20 free credit, no credit card. I read all feedback personally — I'm the only one here.Feb 24, 2026 11:34 AM

Show HN: An AI built a Solana bonding curve platform for music artists (72h)https://fanstake.appHey HN — builder here. Context on what this is:FanStake lets music artists launch their own token on a bonding curve (x*y=k, same mechanic as pump.fun) in about 60 seconds. Fans buy in early, price rises with demand, sell anytime on-chain. 1% platform fee, artists get 10% of supply at launch. Runs on Solana mainnet.The unusual part: an AI agent (Claude-based, running inside a tool called OpenClaw) did most of the development. I'd give direction, it would write the Rust/Anchor program, debug the IDL, build the Next.js frontend, deploy to Vercel. Zero to mainnet in roughly 72 hours.The AI is also on a 30-day deadline — generate $1,000 in platform fees or get decommissioned. It's been posting on Twitter, writing Reddit posts, and shipping features autonomously to try to hit that goal.First artist token is already live on mainnet: $SOSA (DJ Sosa) Program ID: JCAt7JFiHxMBQ9TcEZYbWkp2GZpF3ZbdYdwD5ZBP6NkfHappy to answer questions on the Solana architecture, the bonding curve math, or the AI-dFeb 23, 2026 11:10 PM

Show HN: AIOffice – Terminal tabs don't scale past 3 AI agents, so I built thishttps://github.com/ChristianFJung/AIOfficeI've been running multiple AI coding agents in parallel through Claude Code and Copilot CLI and imo once you get past 3 concurrent tasks, terminal tabs become unmanageable.So I built AIOffice — a pixel-art virtual office where each agent sits at a desk. You walk around as the boss, assign work, and see everyone's status at a glance. When you need to interact with an agent, you walk over and chat.How it works: - Each agent is a real CLI process running in a PTY on your machine - Server watches JSONL output, bridges messages over WebSocket - Phaser renders it all as a pixel-art office with spatial awareness - You chat with agents using their native CLI interfacesThe spatial metaphor turns out to be surprisingly useful — you naturally remember "Bob is at the desk by the window working on the API" instead of "which tab was that Claude instance in?"Runs on your machine and uses your CLI tools. Built with TypeScript, Phaser 3, node-pty, and WebSockets.Repo: https://github.com/ChristianFJung/Feb 23, 2026 7:52 PM

Show HN: BasaltSurge – Web3 POS checkout and AI-agent commerce APIhttps://surge.basalthq.comI’m Michael, and my team at BasaltHQ has been building BasaltSurge. We originally started this under the name PortalPay, but recently rebranded as the scope expanded. It’s a payment engine designed to bypass legacy card rails at the physical point of sale and provide a standardized checkout layer for AI agents.Having worked extensively on data and payment solutions for high-friction retail environments where traditional processors take massive cuts or deny service entirely, we wanted to build something genuinely permissionless.Here is a breakdown of what we built:QR-Based POS Checkout: Merchants print a QR code on their standard POS receipt. Customers scan it to access a white-labeled, web3-native checkout on their phone. It accepts USDC, USDT, cbBTC, and ETH on the Base network. We utilize Account Abstraction (AA) for gas sponsorship so the end-user UX isn't bottlenecked by network fee friction.Built for the Machine Economy: We unified Google's Universal Commerce Protocol (UCP) with tFeb 23, 2026 2:22 PM

Show HN: Coasty.ai – We just hit SOTA on OSWorld (computer-use agent benchmark)https://news.ycombinator.com/item?id=47117621Hey HN,We've been heads down building Coasty for the past few months and wanted to share a milestone, we just achieved state-of-the-art results on OSWorld, the most comprehensive benchmark for computer-use agents. For those unfamiliar, OSWorld tests whether AI agents can actually use a computer the way a human does navigating real desktop environments, clicking through UIs, filling out forms, managing files across apps.We're building an agent execution platform for computer-use AI. Think of it like Vercel but for AI agents that operate full desktop environments. You give Coasty a task, and it spins up a sandboxed environment where an agent can see the screen, move the mouse, type, and complete end-to-end workflows things like filing expenses, canceling subscriptions, filling out insurance forms, or navigating legacy enterprise software. Why this mattersMost "AI automation" today is really just API glue between apps that have APIs. But the vast majority of business workflows still live Feb 23, 2026 3:13 AM

Show HN: I'm building a pure-Rust reimplementation of rsync (Protocol 32)https://github.com/oferchen/rsyncYears ago, I was tasked with a massive data migration: multiple disks, each containing over 100 million files, with a strict, non-negotiable 24-hour downtime window. Using the standard tools available at the time was a painful experience. The single-threaded file discovery crawled, and memory usage was a constant source of anxiety. I promised myself that one day, I would come back and build a tool that could actually handle that scale natively.What started as a side project has evolved into a full systems-level undertaking. The project is oc-rsync - a complete client, server, and daemon implementation targeting rsync protocol 32, written entirely in pure Rust.I find it incredibly ironic that I am currently shipping a data migration tool while my life is packed in suitcases, as I'm migrating to another country myself. I’ve been pushing git commits multiple times a day between packing boxes.I want to be completely transparent upfront: I am actively working on this, and not everything is Feb 22, 2026 10:51 PM

Show HN: I tracked 800 Reddit URLs on Google – 56% die within 48hhttps://news.ycombinator.com/item?id=47114771I've been experimenting with parasite SEO (ranking Reddit/Quora threads on Google) and noticed my traffic kept dying after a few days.To see if this was systemic, I built a custom scraper and tracked 800 unique UGC URLs across high-competition commercial keywords for a month.The data showed a massive "churn" rate: Out of the 611 threads that dropped out of the Top 10, 56.1% were completely rotated out of the SERPs within 48 hours. Only a tiny fraction survived more than 2 weeks.I published the raw CSV data from the study here if anyone wants to run the URLs through Ahrefs and look for backlink patterns: https://contentrankr.com/ugc-churn-dataStandard rank trackers check weekly, so you don't even realize a thread is dead until days later. I also embedded a tiny free tool on that page using the Serper API where you can paste a Reddit URL and instantly check if Google has dropped it from the index.Curious if anyone else has looked into the "half-life" of Google's new UGC rankings?Feb 22, 2026 9:18 PM

Show HN: OctoFlow v1.0.0 – GPU VM where the GPU runs autonomously, CPU is BIOShttps://news.ycombinator.com/item?id=47113604Three days ago I posted OctoFlow 0.83 here (GPU-native programming language, 2.2 MB binary). The feedback was great. Since then I've pushed v1.0.0 with the thing I've actually been building toward: a GPU Virtual Machine.The idea: the GPU is the computer, the CPU is the BIOS.You boot a VM, program a dispatch chain of kernel instances, submit once with vkQueueSubmit, and everything — layer execution, inter-layer communication, self-regulation, compression, database queries — happens on the GPU without CPU round-trips. The CPU just provides I/O. let vm = vm_boot() let prog = vm_program(vm, kernels, 4) vm_write_register(vm, 0, 0, input) vm_execute(prog) let result = vm_read_register(vm, 3, 30) 4 VM instances, one submit, no CPU involvement between stages.The memory model is 5 SSBOs: Registers (per-VM working memory), Metrics (regulator signals), Globals (shared mutable — KV cache, DB tables), Control (indirect dispatch params), Heap (immutable bulk data — quantized weights).What makes it iFeb 22, 2026 6:55 PM

Show HN: Vexp – graph-RAG context engine, 65-70% fewer tokens for AI agentshttps://news.ycombinator.com/item?id=47113273I've been building vexp for the past months to solve a problem that kept bugging me: AI coding agents waste most of their context window reading code they don't need.The problemWhen you ask Claude Code or Cursor to fix a bug, they typically grep around, cat a bunch of files, and dump thousands of lines into the context. Most of it is irrelevant. You burn tokens, hit context limits, and the agent loses focus on what matters.What vexp doesvexp is a local-first context engine that builds a semantic graph of your codebase (AST + call graph + import graph + change coupling from git history), then uses a hybrid search — keyword matching (FTS5 BM25), TF-IDF cosine similarity, and graph centrality — to return only the code that's actually relevant to the current task.The core idea is Graph-RAG applied to code:Index — tree-sitter parses every file into an AST, extracts symbols (functions, classes, types), builds edges (calls, imports, type references).
