GrayCloud
I miss Dark Sky, so I built my own weather app. Here's how GrayCloud works: * Raincast: minute-by-minute rain prediction and accumulation tracking for your exact location * Forecasts: 10 day forecasts use multiple high resolution sources and correct for bias at your location. * Alerts: rain starting, stopping, severe weather, daily summary and more * Widgets: home and lock screen widgets * Multi-platform: apple watch and mac apps I use NOAA and ECMWF models for core weather data and a custom model to compute rain accumulation and the next 60 minute radar movements. I also offer Apple WeatherKit as an alternative weather source.
Hydron
Hi HN, this is Prashant from H2Loop. Embedded engineers that we work with were annoyed that generic AI tools hallucinated register addresses, generated code for peripherals that don't exist on the chip and mixed up timer quirks between similar platforms like STM32F4 and F7. The code looks clean but it just won't boot. This made them go back to the datasheet every time. So we built Hydron, an AI tool that writes datasheet-grounded code for your hardware. Demo: Hydron setting up sleep-mode CPU logging for an onboard temp sensor on an STM32U385 - https://boot.hydron.sh/zzzDemo First, we've pre-indexed 580+ platforms and peripherals. Most of what you'd use in a robotics, UAV, or IoT build: common dev platforms like STM32, ESP32, RP2040, AM6 families, plus the IMUs, GNSS modules, motor drivers, and baros that ship around them. Ask about a peripheral, the answer comes from our KG and the actual datasheet. Second, you can bring your own context and share it with your team. Hydron indexes PDFs up to 5000 pages, plus a whole host of various file types and even ZIPs of full C/C++/Python codebases up to 250MB. One engineer indexes the HW, BSPs, and datasheet pack once. Anyone else can reference it from their own Hydron agent. Third, HW-SW development happens in your editor or terminal. Agentic serial monitor is live today. GDB integration, and an AI log reader land in the next two weeks. Up next, we're focused on closing the hardware-software loop. We're building more HIL debugging capabilities, deeper target awareness, and support for additional platforms. If you work on embedded SW we'd love your feedback on where today's tools fall short and what you'd like to see next.

Boxes.dev: ditch localhost; run Claude Code and Codex in the cloud
Hi HN, we’re Nick and Drew, and we’re building boxes.dev – the first cloud-only agentic dev environment (ADE) that gives every Codex and Claude Code agent its own cloud computer. We’re two engineers who previously built Gem (co-founder/CTO and first hire), and we spent the last year coding almost exclusively using Codex and Claude Code. It’s been a huge change to how we code, and it’s been exhilarating seeing the models keep getting better – but we eventually realized that developing on localhost was holding us back: - Git worktrees are clunky to set up and use for parallelizing work - It’s 2026, but somehow everyone is still walking around with laptops cracked open or SSHing into mac minis in their garage so their agents don’t stop working. - Mobile is treated like an afterthought even though coding is just texting now We started hitting resource constraints when multiple parallel agents test their own work by running the full app locally. - We tried different products, but couldn’t find any that solved all of our pain points – so we pivoted and decided to just build the ADE we wanted for ourselves. Boxes.dev is a desktop and mobile app that lets you run Claude Code, Codex (using your subscription!), and the full dev environment for whatever you’re building, all on remote compute. It’s similar to Conductor or the Codex desktop app, except everything is in the cloud. We use coding agents to scan your local dev setup and port it to the cloud. Then every Claude Code/Codex thread starts from a snapshot of the full setup, with its own filesystem and compute. No more git worktrees, no more cracked-open laptops, and your coding agents can actually test their work end-to-end because they can run your full app in isolation. We’ve mirrored the Claude Code and Codex UX to feel natural to power users, and also have a fully-featured mobile app (no handoffs or remote control), plus scheduled automations and a Slack integration. We’re obviously biased, but we’ve been building boxes.dev with boxes.dev for months and it’s honestly been a gamechanger. It’s hard to go back once you realize how much localhost has been limiting you; based on early feedback from beta testers, we’re increasingly sure that cloud is the future of agentic coding. We’d love for you to experience it yourselves! Would appreciate any feedback – and happy to answer any questions on this thread.
ssh late.sh
So first, what are we? A Clubhouse inside the terminal, where people can take a break, chill, chat with others all around the globe, listen to music, play some games, or paint on a live artboard :). ssh late.sh (or use the companion CLI) That's all. No passwords. No OAuth. No accounts. Your SSH key is your identity. Honestly, I've been a little nervous to post this. I wanted the Clubhouse to be something I'm genuinely proud of before sharing, and I think we are finally there :) There is so much here, so I'll really try to focus on the core: - full-scale chat, mentions, rooms, public and private, DMs, reactions, image previews, full-quality images, icon picker, anything you need - music, hop into the YouTube booth (WebView using wry) to listen to the community playlist, submit, vote, skip, or listen to 600+ server tracks divided into three categories (lofi, ambient, classical) - games, single and multiplayer, sudoku, minesweeper, tetris, snake, nonograms, poker, blackjack, chess, and much more. Leaderboards and badges! First truly server-wide game is in the PR! - live artboard, think r/place but in a TUI, draw, paint, or just enjoy. Daily and Monthly snapshots, check them out here: https://late.sh/gallery - shop, buy a new fully-dynamic bonsai to take care of, or maybe a new aquarium, fill it with ASCII fish, or what about a new pet to play with? Quests, daily and weekly + streaks to help you win more chips - news, rss/atom feeds, connect your own, share with others, auto-generated summaries with a nice ASCII thumbnail shared globally - directories, a dedicated space to showcase your projects, another to build your "work" profile, and it all rolls up into your live web profile: https://late.sh/profiles (someone has already been hired thx to it!), and another one for co-op tools, right now a canvas builder inside the TUI - and the NEWEST addition, VOICE chat :) without a browser! This has already grown into a team effort. Amazing people, amazing contributions, amazing vibe. Big ones in the pipeline: more BBS/full-scale server, real-time games :) Hop in, take a break and enjoy ;) Code: https://github.com/mpiorowski/late-sh Landing: https://late.sh Demo: https://late.sh/play License: FSL-1.1-MIT
Uruky (EU-based Kagi alternative) now has Image Search and URL Rewrites
You can get a 2h free trial by solving a proof-of-work captcha when topping up your account for the first time. If you'd like to learn more, an independent interview was posted a couple of weeks ago [1], and the FAQ [2] has a lot of information as well. For the source code sharing, we've talked with lawyers and are inclined to no longer require the NDA/NCC for privacy reasons shared with us before (signing requires identification), but instead use a source-available permissive license that doesn't allow competition, like PolyForm Shield [3] (we do still have about 6 months before finalising a decision, here). This does come with a lot more risks for us (it's harder to track down if someone publishes the code or uses it against the license), but given we've already passed 100 monthly active accounts, we're feeling more confident it's an acceptable risk. The plan is to give logged in accounts (who are 12 months old or more) a way to download a ZIP of the current code base that's in the server. Obviously there's no easy way to prove that's the case, but we're open to ideas/suggestions if someone here has them. [1]: https://theprivacydad.com/interview-with-the-engineer-of-uru...

Ano
Hi HN! I'm building Ano because I was tired of Slack's bloat and sluggishness, and never got any value out of their agent implementation. Ano is built local-first for speed (using Rocicorp Zero), focused on communication, and lets you use your own code agent as an assistant (Claude in my case, but it works with Codex too). I use the code agent to summarize anything unread (linking back to what matters), respond with context, and share data to and from connected tools (GitHub, Posthog, Attio, etc). Using your code agent for this might sound counter-intuitive, but to me it's the most powerful agent I use. It already has connections to my tools, and now it has access to Ano for communication too. The agent lives in an in-app shell, and Ano also has a CLI, so you can read and message into the chat from whatever terminal you're already using. Basically: Slack, minus the noise, with your code agent doing the work. Early days, but you can download the app and try it (macOS and iOS for now, more to come!). Would love your feedback. It's free, but you bring your own code agent account.

A searchable archive of declassified UAP/UFO files, news, and analysis
Hey HN! Y’all are great. It is so fun to build things these days. I wanna show off this archive that I conjured to run at home for consuming the recently releases of UFO files from the US government. This started as a Mac Mini-hosted project that I executed with my OpenClaw over Discord. After showing this to a few friends, I decided to get it online and find a catchy domain. Cloudflare was the perfect hosting choice. There’s a lot of bonkers things out there going on, so I added human curated “Signals” - news, analysis and discussion of UFO and adjacent news. The backlog of signals was informed by the links shared between myself and my first tech boss. We have both seen things that these files help confirm. As part of a reason to bring people back, I asked my assistant to do some digging into the data and come up with “Insights”, a dedicated section on the site that includes the responsible LLM in the byline. There a media pipeline for these insights using Remotion to generate social-media ready videos that I can upload to TT, IG, and YouTube. I built this for fun. Mostly with Ollama-powered GLM 5.1. Runs on Cloudflare Workers, D1, R2. Keyboard navigation within the doc viewer is blazing fast. OpenClaw is my CMS. Eventually, I hope to find some passive revenue through ethical ads if I get enough traffic. I think there is an audience for this. Right now, this is helpful with sharing the WTFs (and psyops) of the world with friends. Hit me up with questions! Stay rad, HN!
