Show HN: Tried some experiments with architecture for Long term memory for LLMhttps://github.com/faisalhussain-devs/MindCache/tree/collapsed_treeThe main ideas that survived the experimentation are:using four memory types — user, knowledge, episodic, and decision memories, each with different lifecycles, different roles and different token budget in the retrieved context. Decision analysis + anchors — decisions can evolve overtime so they can be active or superseded or conditional instead of remaining as unrelated memories. we keep the track of decision memory which is active, superseded or conditional with additional context and using such active decisions related to the query as anchors to further retrieve memories using lexical bm25 often helps. Smart injection — New memories aren't simply assigned to a topic based on similarity. An LLM-guided ingestion step uses the existing topic structure as context to decide where a memory belongs and how it relates to what is already there. This lets the hierarchy grow dynamically instead of becoming a collection of isolated memory nodes.Hierarchical summaries — MindCache adapts the staAug 12, 2026 8:03 PM

Show HN: Llmem – Local persistent memory for AI coding, no embeddingshttps://github.com/netrixone/llmemHi folks. This part of AI coding always felt really dumb: after working on many projects it repeats the same mistakes, uses awkward patterns or looks up stuff over and over. It just does not remember. Skills exists, but I don't like maintaining lots of markdown files. There were other solutions for this and I'm sure there are even more now, but I simply did not fancy those for one reason or another.So I wrote my own good-enough persistent memory which easily integrates with all AI coding tools I use. Lightweight, local, 1 Go binary + 1 SQLite file. Speaks MCP + good old REST API I can curl.After some testing I settled on BM25 lexical search with optional WordNet synonym expansions - no embeddings, no vector DB, no external API calls. A downside is English memories only, but that's OK for me.Memory_context pulls priority-tagged memories at session start, auto-consolidation merges near-duplicates to prevent bloat. Later I added optional memory types, project scopes and hashtags.I've beenAug 7, 2026 8:40 AM

Show HN: AppScout – App Store downloads, revenue and widgetshttps://apps.apple.com/us/app/appscout-app-metrics/id6770866569Hey hackers!Signing in to App Store Connect just to check downloads or MRR is a friction. I wanted a simpler way. Ideally, just to look at a widget on my iPhone. There are some apps, but the design and implementation made me think here's a gap that I can potentially fill it with a new polished product. So I've built this app.It took me several months to start beta testing. But then I got feedback from users that they don't really want to share their App Store key credentials with a third-party app that uses a backend and collects data. So, I spent one more month pivoting to a private app by dropping a backend and storing credentials on a user's device in a keychain. So, now the app directly talks to Apple's API and there's no account registration. You add a team key - the app fetches data. App also uses background tasks to fetch most recent data so you don't need to open it every day to keep the data fresh. And as a final point - I added widgets to both home and lock screens.Please letAug 5, 2026 4:09 PM

Show HN: Sagorax, a Three.js/WebGPU Arena Shooter in the Browserhttps://sagorax.com/I built Sagorax because I missed the speed and simplicity of UT99 and UT2k4. It now has both Instagib and classic weapons Deathmatch with plasma combos, flak, shotguns, charged rocket salvos, loadouts, adrenaline abilities, tactical bots and full controller support.No installation, just pick a gamertag and play: https://sagorax.comThe client is built with TypeScript, Three.js and WebGPU. Under the hood it uses FSR 3-based upscaling, adaptive dynamic resolution, GPU pipeline warmup, screen-space reflections, dynamic lighting and shadows, visibility culling and a custom post-processing pipeline.Multiplayer is next if there is enough interest (looking good so far).If you had told me a few months ago that this would be possible in a browser, I wouldn’t have believed you. But Opus 5 + GPT-5.6-Sol = GODMODE.Feedback is very welcome.Aug 4, 2026 7:50 PM

Show HN: Draco – A single-binary, self-hostable Firecrawl alternative in Rusthttps://github.com/0xchasercat/draco/Scraping modern websites has become a massive headache. You basically have two choices: pay for an expensive API like Firecrawl/Browserbase, or run a fleet of headless Chrome instances that eat 1GB of RAM per page and still get blocked by Cloudflare.I built Draco to fix this. It’s a fast, single-binary web scraper written in Rust. You point it at a URL, and it spits out perfectly clean Markdown or structured JSON for LLMs.The secret sauce is that it doesn't just boot a browser for every request. It uses a tiered escalation engine:Tier 1 (Stealth Fetch): Draco uses a custom TLS/JA4 fingerprint to perfectly mimic a real browser's network signature at the packet level. It turns out a lot of anti-bot walls will let you right through if your handshake looks correct. In my benchmarks against sites like Cloudflare and Target, Playwright ate ~500MB of RAM and timed out. Draco bypassed them in under a second using just 20MB of RAM.Tier 2 (V8 Isolate): If it hits a React/Next.js SPA that needs rAug 2, 2026 8:48 PM

Show HN: Collab Word in Web - A collaborative DOCX Editor with MS Word Parityhttps://collab.word-in-web.com/TLDR: Collab WIW is a DOCX editor with MS Word parity that supports real-time collaborative editing. The collab layer is end to end encrypted and uses ephemeral rooms with stable share URLs. Ever collab room lives in only memory. Collaborator saved copies can bring the room back online at the same URL and reconcile offline edits.The MS Word parity DOCX editor: I made a previous HN post about the editor itself. It is a pure JS DOCX editor that renders and edits the original document directly in the DOM instead of converting it into some other format.I benchmarked it pretty heavily against thousands of pages to push for pixel and feature parity, including equations, tables, 3D objects, headers, footnotes, etc... I am not going to get too deep into that because I already posted a ShowHN earlier. The parity report has all of the fixtures I tested and the actual results.Edit: Link to previous HN https://news.ycombinator.com/item?id=48995304The server: The collab BE was actually inspired by Jul 31, 2026 8:28 PM

Show HN: One page personal calendar with hierarchyhttps://news.ycombinator.com/item?id=49119723Hello everyone! actions.life is a one page personal calendar. Unlike traditional to-do lists, which divide information into many pages, this app uses hierarchy to fit everything* on one page.The UI is designed to be predictable, like a physical desk with moveable objects, so nothing gets forgotten. The limitation from this physical design helps with focus and restraint: unlike knowledge bases, which are vast and interconnected, “action bases” should be constraint and scoped, for encouraging action.It complements apps like Notion and Google Calendar, and works for mobile and desktop on iOS 26+ and Chrome.I hope you can give it a shot and become my user! I will fix things and improve things (I've been full-time since 2024).https://beta.actions.lifeJul 31, 2026 6:33 AM

Show HN: Cygnus – A fast, lightweight self-hostable serverless runtime and PaaShttps://cygnus.runI built Cygnus because of a long standing frustration with the compromises needed to be made when choosing a deployment option for web applications.The ecosystem is fragmented into a few distinct camps, each sacrificing user experience or runtime compatibility to balance isolation, startup latency, and their own profit margins.Docker: Heavier and slower because it has to supervise more than web apps. Paying overhead you don't need. MicroVM's: Good isolation, but huge maintenance surface area and substantial overhead. Great for untrusted code, overkill for your own apps. Workerd: Tries to dance around hardware isolation by enforcing an in-process V8 isolate model. Neutered runtime to prevent arbitrary syscall execution. Personally I still find the tradeoff worthwhile for their edge footprint, but I still find myself complaining about it from time to time. Vercel/Managed serverless: Delivers a great developer experience, uses microVM's which is good for compatibility but has a business mJul 25, 2026 12:20 PM

Show HN: Chrome Plugin to Scan HN Page Quickly. (Categorize with Local Model)https://github.com/prabhic/hn-quick-scanRecently I started spending more time reading HN posts, and engaging. Wanted to scan HN pages faster ,that rosonates to me.For me it is easy to grasp if they are in the order of software stack (Hardware, System, Infrastructure, apps, and so on ).Built this chrome plugin that uses Gemini model, to classify. It works but, classification still not great. It is built using claude code cli.on my Mac book pro, Gemini nano model loading takes around 11 seconds, and classification it self takes around 5 seconds. (if sub classification enabled it adds 6 more seconds approx). Model loaded in background thread. And unloads, if not used after 30 seconds. I would say still not pretty usable, without optimized classification time, but it works, to experiment with.Jul 23, 2026 3:20 PM
