Show HN: Chat – Another open-source chat UI for MCP Serverhttps://news.ycombinator.com/item?id=47398628i built this because i’ve been experimenting with MCP and felt there was a need lightweight version for ecosystem.most existing clients felt a bit too noisy and bundled into larger ecosystems, so i wanted simplest/ near plain version that just focuses on end-user chat experience.stack(main): NextJS(App Router) + Vercel AI SDKcapabilities:+ set single MCP endpoint and brand mode(bring your own brand asset) on ENV+ prepare local db or external endpoint(SQLite, PostgreSQL, MySQL)+ choose in-memory(default) or external/ local Redis endpoint+ built-in auth via Better Auth & Resend(optional)+ support file upload with Cloudflare R2+ support location-sharing with LeafletJS and Browser Geolocation or Google Maps Platform+ automatic data cleanup with Trigger(free-tier trigger.dev is ENOUGH)+ auto-detect user location so they dont need to set timezone manually+ locale currently support 10 languages(EN, ID, KR, JP, ES, ZH, DE, NL, FR, IT)+ plain/minimalist interface+ install with single interactivMar 16, 2026 1:17 PM

Ask HN: AI Agents vs. Gateways vs. Harnesseshttps://news.ycombinator.com/item?id=47397737Hi,I'd like to get everyone's take on the different components in the AI Agents ecoysystem. I find the current terminology quite confusing as it's not always obvious what I'll be actually getting when I examine the available options.A lot of things get called Agents, but that term seems hard to define as it often refers to overlapping functionality. To me, agents seem to be currently composed of the following components:## Harnesses- Adds UI and system instructions around an LLM and may also augment it with tools such as memory, tool calls, etc...- Examples are Claude Code, Code, Gemini CLI, pi.dev, ...## Gateways- These connect agents to your communication tool of choice, e.g. Whatsapp, Telegram, Slack, Discord, ...- Examples are OpenClaw and Nanoclaw## Sandboxes- Isolated environments where Agents can run with limited or auditable capabilities- Examples can be from physical ones like separate Mac Minis to docker-agent, agent-sandbox, localsandbox, ...This then takes us to *Agents*:##Mar 16, 2026 11:43 AM

Eliminating UI Bloat in the EraMix Financial Union Dashboardhttps://news.ycombinator.com/item?id=47394092We recently refactored the frontend for EraMix Financial Union. The challenge was displaying dense, multi-source data without the typical "enterprise dashboard" lag.For EraMix Financial Union, we moved away from heavy component libraries to a vanilla, high-end minimalist design. By using a virtualized grid and custom CSS primitives, we reduced our bundle size by 70% and achieved a perfect 100 Lighthouse score.Curious to hear—who else is ditching heavy UI frameworks for custom, lean implementations?Mar 16, 2026 1:36 AM

Help Galaxy Zoo: Tidal Tales Open Cosmic Storybookhttps://science.nasa.gov/get-involved/citizen-science/help-galaxy-zoo-tidal-tales-open-cosmic-storybook/Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks to deep, high-resolution images from the Euclid space telescope, an ESA (European Space Agency) mission with critical contributions from NASA, we can now see these delicate structures more clearly than ever before in unprecedented numbers.Mar 12, 2026 3:41 PM

Ask HN: Can a word game work as a competitive strategy esport?https://news.ycombinator.com/item?id=47347625I've been experimenting with a browser game design problem.Most word games (Scrabble, Wordle, etc.) are either slow or mostly about vocabulary. I wanted to see if it was possible to build one that behaves more like a competitive strategy game — something closer to chess in terms of tension and reversals.The result is a prototype called The Word Gambit. The board grows organically from placed words, and late-game detonations from long words can swing the match dramatically.The surprising thing during testing is that matches often feel more like territory control than spelling.Players also started creating AI opponents ("gladiators") and pitting them against each other, which I didn't originally plan.I'm curious about a few design questions:• Can vocabulary realistically function as a competitive skill in an esport context? • What mechanics would make a word-based game strategically deep rather than dictionary-driven? • Would spectators even enjoy watching something like this?If anyone iMar 12, 2026 7:37 AM

Show HN: Movie site built on a game enginehttps://movie-chain.com/I'm an ex-gamedev (Guitar Hero) who built a movie website that looks like a Trello board. Each column can contain a different movie or cast member. Load pre-made boards or create your own by dragging and dropping between the columns. You can share boards with others.For example, start with Quentin Tarantino’s movies in Column 1, put the cast of Once Upon a Time in Hollywood in Column 2, then put Brad Pitt’s entire filmography in Column 3. Keep going as long as you want, building a "chain" ala Six Degrees of Kevin Bacon.I was frustrated that all popular movie websites are page-oriented: one HTML page per movie or person. I asked myself what a movie site designed in 2026 would look like, in an era when full-screen canvas sites like Miro are common. And then asked what if the site was built on a game engine? I used PixiJS.I ingested TMDB movie data into my own SQLite database head of time, so there are no external API calls at runtime.

Show HN: Trawl – LLM-powered web scraper that calls the AI once - runs pure Gohttps://news.ycombinator.com/item?id=47297522Every scraper I've written has the same failure mode: it works for three months, a site redesigns, and my CSS selectors silently return empty strings. The data is still right there on the page — a human can find it instantly — but the scraper is blind.Trawl fixes this by splitting the problem. You describe what you want: trawl "https://books.toscrape.com" --fields "title, price, rating, in_stock" The LLM (Claude) looks at one sample item and derives a full extraction strategy — CSS selectors, attribute mappings, type coercion, fallback selectors. That strategy gets cached. Every subsequent page with the same structure is extracted with pure Go + goquery. No API calls, no token cost, full concurrency.The key insight: LLMs are good at understanding HTML structure, but you don't need them to extract 10,000 rows. Use AI for intelligence, Go for throughput.When a site redesigns, the structural fingerprint changes, the cache misses, and trawl re-derives automatically.You can preview exactly Mar 8, 2026 2:18 PM

Show HN: PolyClaude – Using math to pay less for Claude Codehttps://github.com/ArmanJR/PolyClaudeHi HN!I built this tool specifically for Claude Code users who hit the 5-hour rate limit wall mid-flow. There's no official plan between Pro ($20/mo) and Max ($100/mo). it's a fixed gap with nothing in between.The workaround most people do manually: running multiple Pro accounts and switching when one is limited. This actually works, but naive rotation wastes a lot of capacity. When you activate an account turns out to matter as much as which one you use. A single throwaway prompt sent a few hours before your coding session can unlock an extra full cycle.PolyClaude automates this. You tell it your accounts, your typical coding hours, and how long you usually take to hit the limit. It uses combinatorial optimization to compute the exact pre-activation schedule, then installs cron jobs to fire those prompts automatically. When you sit down to work, your accounts are already aligned.It's free and open source. Install is one curl command, then an interactive setup wizard handles the rest.RMar 7, 2026 10:24 PM
