Show HN: Lightweight Task queue on Erlang/OTP, SQLite-backed, no overengineering Setting up Kafka or such enterprise oriented software with their clusters or dedicated servers is heavy and bothering enough that most small teams or indie hackers skip it entirely and making compromise to use in-memory queues. I wanted something in between: a persistent queue that is simple to run (one binary, which makes one sqlite db), gets real fault isolation and crash recovery due to Elixir, easy to inspect (open ezra.db in any SQLite browser and see every task), and requires no new client library - it speaks the Redis Streams wire protocol, so any Redis client in any language just works out of the box.

Show HN: LLMRender, a 10kb Markdown+LaTeX renderer for React https://bit.ly/4xx2E4u

Show HN: LLMRender, a 10kb Markdown+LaTeX renderer for React I've been using the popular React Markdown renderers with Katex and Prism.js for rendering my Markdown and LaTeX, but was tired of having to bundle 300kb+ of min+gzip JS only for this (1.2MB+ of plain JS!). So I created a small Markdown renderer that does it all in a tiny package. I added a small playground to the homepage, please feel free to try it and let me know what you think! It's not perfect, it's definitely not "correct" in that I'm using Regex internally instead of a proper AST parser, but for my usecase and the majority of Markdown out there, this works perfectly fine (cue the StackOverflow post [1]). It's also conservative for this reason; no HTML by default, parsing wrong content produces escaped HTML entities instead of XSS.

Show HN: Manob: A social media plaform without algorithm, ads, or data-tracking https://bit.ly/4oqKyN9

Show HN: Manob: A social media plaform without algorithm, ads, or data-tracking I built Manob because I kept running into the same frustration with every major social media platform. A feed I couldn't control, content that I couldn't trust, and also a sense that I (my user data) am the product, not the user. I talked with people about these thoughts and concerns, and added my personal observation. I built this instead: - Chronological feed only. No ranking, no algorithmic shuffling. You follow people, you see all posts from all users, or choose to see posts from friends, pages you follow, and groups you are part of. - Built-in fact-checking and bias detection across text, images, and video. With Human-in-the-loop & AI combined in the process, AI detects, analyzes, and moderates posts, and every contested moderation decision is reviewed by a human against a published set of principles (not just personal judgment only). - Per chat AES-256 encryption. We designed a way that currently, if a chat is attacked and compromised, it doesn't have any effect on other chats or the platform in any way - this is constantly being improved, and security is my top priority. - No ads currently. Your data is never sold or shared (minor data is stored, all in encrypted strings) - Child safety filtering is built into the content layer - Pseudonymous mode for speaking about sensitive topics - A built-in news feed The moderation system is designed to evolve; it is more like a constitution than a rulebook. The principles are fixed but can be amended as the platform grows and severe cases emerge. The goal is to detect as accurately as possible, systematically, over claims of neutrality and move on. I'm still working on figuring out monetization. I'm thinking of contextual ads that work based on the viewing page's contents, and not on your behavioral profile. Additionally, other features like the job board and commercial tools are also an option. None of this is live at the moment, and tbh, I'm still figuring it out. The platform is currently LIVE with a small early community of active users. I'm building this solo. I'm happy to answer your questions/feedback/suggestions... https://bit.ly/3QccXtS June 12, 2026 at 06:06AM

Show HN: A Claude Code statusline that shows live World Cup scores Hey HN, I built this a side project because I'm a soccer fan that has been vibing and tokenmaxxing with Claude Code maybe too much. So, the World Cup is here and it was the perfect excuse to build and ship something from 0 to 1. Enter Claudinho, a CLI and MCP that puts World Cup scores on your terminal. No signup, no account, no data collection. The components are: - status line in Claude Code with live scores rendered always from cache, no polling. - userPromptSubmit hook so Claude gets score updates mid vibecoding session, only during a live match. - A standard MCP server and a CLI with options to see groups, standings, matches and market signal info. More details in Github. Let me know what you think, I hope you find it fun and useful! Not affiliated with FIFA or Anthropic. https://bit.ly/4fHn1W8 June 12, 2026 at 03:31AM

Show HN: Deploy personal apps with your agent via Buildy https://bit.ly/3Sma0Yd

Show HN: Deploy personal apps with your agent via Buildy Hi HN, I'm one of the creators of Buildy. More and more people seem to be building personal software, including myself. But I keep re-implementing the same things: authentication, database setup, creating an API/MCP server to integrate them into my AI agent. We built Buildy for LLM generated personal apps. How it works: Buildy exposes an API and MCP that the agent can call with an ES module plus an optional UI and CSS. We run the ES module on a workerd isolate with a persistent KV store, then release your UI to a live URL only accessible by you. Not only that, but your app APIs are exposed securely over both HTTP and MCP so your agent can call them and use the apps you build (log a meal, create a workout plan, update a note, etc.) If your AI chat client supports MCP Apps, we can also render your app inline via an iframe. This works today with ChatGPT and Claude. Here is an app I built to track my nutrition: https://bit.ly/4v8A9Zd... ← You can actually claim this app and remix it with your own agent. To ship a completely new app, drop this prompt into your agent: Read https://bit.ly/3RTTAX3 then help me create my first app. Or check out our landing page ( https://bit.ly/4up5WUl ) to use our ChatGPT app or connect it to Claude via MCP. I personally use apps I built every day. I'd love to hear from other people building and using their own personal apps. Would love feedback from people building and using their own personal apps. https://bit.ly/4up5WUl June 12, 2026 at 01:08AM

Show HN: Magenta Real-Time Music Generation Locally on iPhone, Without the GPU https://bit.ly/4xqKwsU

Show HN: Magenta Real-Time Music Generation Locally on iPhone, Without the GPU Last Thursday, Deepmind released Magenta Realtime 2 , an open source music generation model. They said it could run on Mac, but not iPhone. As a v̵i̵b̵e̵ ̵c̵o̵d̵i̵n̵g̵ ̵a̵d̵d̵i̵c̵t̵ agentic AI maxxi and person who has melted iPhones before (link at bottom), I took that as a personal challenge and made it my weekend project. On Saturday, I got it to run for 10min straight on an iPhone 12 Pro from 2020 without melting the phone or - shockingly - touching the GPU. How? I chopped the model up into 5 pieces and set them each to run on different parts of Apple's system on a chip (SoC). My past experience taught me that if you can actually leverage it, the iPhone's NPU is incredibly powerful, and power efficient. If you're doing sustained real-time generation for long periods of time on a device without a fan, you gotta use the neural engine or else you will melt the device. See: https://bit.ly/4ot5K5m The Apple Neural Engine has a ton of constraints, the main one being that it only accepts fixed shape inputs, and only supports some architectures -- which is why I chopped the model up into pieces. But it works! And I wrote zero lines of code by hand. Back when I was running VC-backed companies, I would have needed a small team of grumpy greybeard engineers to do this and it would have taken 2-6 weeks. Now I can feed my own nerd fetish and do this stuff myself. Next up: I'm building an iPhone app that ties into your heart rate, movement data, location etc to generate a real-time soundtrack to you life. What a time to be alive! update: Demo video of it running on my iPhone 15 Pro: https://bit.ly/3RY7Gqh https://bit.ly/49OqDls June 10, 2026 at 11:22PM

Show HN: Ustps (UDP Speedy Transmission Protocol Secure) and USSH https://bit.ly/49JTG9F

Show HN: Ustps (UDP Speedy Transmission Protocol Secure) and USSH Hi HN, Over the last few days I've been building USTPS (UDP Speedy Transmission Protocol Secure), an experimental encrypted transport protocol built on top of UDP. The primary goal of USTPS is low-latency video streaming. A server can take a video source and expose it through a USTPS endpoint, while Linux and Android (Termux) clients receive the stream and expose it locally to applications such as VLC, mpv, and FFmpeg. Although streaming is the main focus, USTPS is not limited to media delivery. It can also be used for other reliable encrypted UDP-based applications, which is why I built USSH on top of it. Some of the main design differences compared to TCP-based transports are: - USTPS is reliable but unordered. - If packet N is lost, later packets can still be accepted and processed immediately. - Missing packets are recovered through selective retransmission. - Ordering is handled by the application layer when needed. This means the transport layer itself does not introduce Head-of-Line Blocking. The tradeoff is that applications which require ordering must implement reordering themselves. I consider this a reasonable tradeoff because it avoids forcing every application to pay the cost of transport-level ordering. For media player compatibility, the default USTPS client creates a local TCP endpoint at 127.0.0.1:1238. The client maintains a small reordering buffer (350 ms by default) to give retransmissions time to arrive before forwarding data to the local TCP stream. This allows existing software such as VLC, mpv, and FFmpeg to work without modification. USTPS currently provides: - Reliable delivery using ACKs and selective retransmissions - X25519 key exchange - AEAD encryption (AES-GCM and ChaCha20-Poly1305) - Optional unordered live output mode - Stream position metadata - Multi-client support - Local TCP compatibility output - No congestion control (currently intentional) While developing USTPS, I also built USSH, an SSH-like remote shell running entirely over USTPS. USSH uses the same unordered transport underneath, but the client reconstructs and orders terminal data before presenting it to the user. This prevents terminal corruption while still allowing the transport layer itself to remain unordered. USSH includes: - Interactive terminal sessions - PTY support - Password authentication - Host key verification (TOFU) - End-to-end encrypted communication through USTPS I'm currently using USSH from my Android phone through Termux to manage my VPS. The project is very young (less than a week old) and is primarily experimental and educational. I'm interested in feedback from people working on transport protocols, streaming systems, SSH implementations, QUIC, SCTP, and networking software.

Show HN: NoSuggest – Watch YouTube without the recommendation algorithm https://bit.ly/4vCZ475

Show HN: NoSuggest – Watch YouTube without the recommendation algorithm NoSuggest is a quiet act of resistance against YouTube algorithms always trying to pull you into a loop of unlimited videos in turn into unlimited screen time. With unending side cards of videos, auto-play, what's next suggestions, YouTube shorts and notifications, users will be doom scrolling for many hours in a day. I faced the same problem. Acknowledging that, not all content in YouTube is bad. There are educational videos, genuine news contents without political bias which is very hard to find outside YouTube and many other good relaxing, entertainment stuff. NoSuggest lets you only follow the YouTube channels you like and removes all types of recommendation YouTube has. So you don't waste time on watching things which you never wanted to watch anyways. UI is very simple. You add your favourite channels in "Channels" tab and latest 5 videos per channel excluding shorts would appear in "Feed" tab. "Search" tab is to search for specific videos to watch and "Saved" tab is to bookmark any video you want to watch later. Intention of NoSuggest is to provide whatever is necessary to extract whats good from YouTube all inside NoSuggest and leave out bad parts. NoSuggest works in any devices. Install it as an app (PWA) in android and iPhone, or simply open in browser in laptops. No sign-in, no account creation or no card details. NoSuggest won't even ask your name. Total privacy for the users. Parents can add the channels and save some educational videos and lock it with the pin for kids mode. Kids won't be able access unwanted additive contents inside NoSuggest. Completely free, no string attached. Source available in Github through NoSuggest website. I would love genuine feedback. Thank you very much for your attention on this matter. https://bit.ly/43hVGCv June 3, 2026 at 10:14PM
