Show HN: How many people live within an hour walk of you?https://blockatlas.com/tools/radius/walkI've been building a bunch of US geography tools/games/visualizations and thought folks on HN might like this one. There are also drive-time and bike-time tools available on the same page.For folks interested, all of the data comes from OpenStreetMap and the US Census at the moment - OSM for routing and points interest and the US Census for population data.Anonymous users can use it 5x/day. I put up a waitlist page to gauge interest in a paid version but there's no way for the public to make an account - feel free to bypass the limits in an incognito tab.The site is US-only for the time being - sorry for international folks!Jul 28, 2026 12:05 PM

Show HN: APIs as First-Class Citizenhttps://news.ycombinator.com/item?id=49081439A few years ago, I encountered neovim and a new concept: APIs as first-class citizens.As I used it more and more in my work, I became increasingly aware of its importance.Exposing the software's state and operations through APIs greatly improves the debugging experience, provides extensibility, and makes it very convenient for other programs to call them.On the other hand, centering on APIs can also improve program structure, because the entire program is written around a single context.Currently, I usually use HTTP as the external interface because it allows for operations using curl and exposes these operations to the front end.Previously, I used Axum as the HTTP server and utoipa to export the API to OpenAPI. Then, I used tools to convert the OpenAPI as TypeScript code for front-end.However, I quickly encountered some problems. First, utoipa's documentation isn't generated during the build process; I need to run `cargo test` separately to generate the OpenAPI documentation. Second, Jul 28, 2026 9:28 AM

I have 6 emails :sob: and grabbing OTP's from them can be hard, even with a good email client. So I built this tool to make it easier for me! I made it in native Swift :)I did this for Hack Club Horizons, which is an event where they're flying teens to 7 countries around the world for hackathons!

Show HN: Let's Seal – Let's Encrypt for document signing, free and self-hostedhttps://github.com/letsseal/letssealTLDR, Let's Seal gives the finger to Adobe and every doc signing tool (docusign, google, etc) who pay to play with the Adobe Approved Trust List and then charge you for something that should be free.Currently even the person checking if a document/contract is sealed or code is authentic has to also be inside the same Adobe walled garden too. Verification, the part that should be free is the part everyone charges for. Thats the shape Let's Encrypt fixed for TLS, and I wanted the same thing for documents and files.The core idea therefore needed to go a bit beyond e signatures and i created an open standard (SEAL), plus free tools that implement it.When you seal a file, three independent things happen.1. it gets a signature from a certificate authority, chaining to a public root. 2. its record is appended to an RFC 6962 transparency log. and 3. its SHA256 is timestamped on a public blockchain (Bitcoin) via OpenTimestamps. Those three give you integrity, transparency and a timestamped prooJul 27, 2026 3:52 PM

I'm a 2x founder building some challenging software, some easy software, and some curiosity based tools that I've just always wanted to be a part of!So here is Scalattice.Scalattice is an OpenAI-compatible inference API. You keep the OpenAI SDK, swap base_url + API key, and call open models (Qwen3, Llama 3.3 70B, Gemma 3, DeepSeek R1, etc.). Inference is performed by a provider node on our distributed network of consumer hosted inference machines, we run an open source agent (https://github.com/scalattice/scalattice-agent) which works in Rust to run the inference and get the provider paid.In short, anyone can become a provider, offer up their machine with our Windows/Linux Rust agent, and earn some extra cash, or start a farm of machines to make big bucks.I decided to build some innovative behavioural traits to the API for higher performance/security: 1. output vetting - Scalattice Cloud vets the response agJul 26, 2026 5:43 AM

The Cost of Seamlessnesshttps://news.ycombinator.com/item?id=49048352The Hidden Cost of Frictionless Technology Taotuner — 2026I recently asked an AI assistant for restaurant recommendations. It listed five places, complete with ratings, distance, and popular dishes. I picked one, went, had a fine meal. Later, when a friend asked what I'd eaten, I couldn't remember the name of the restaurant.The experience wasn't bad. It was frictionless. And it left almost no trace.We've built tools that eliminate the gap between want and satisfaction, question and answer, curiosity and resolution. We call it seamlessness. We've assumed it's progress. But the gap wasn't inefficiency — it was where memory, judgment, and understanding used to form.What if removing it is making us less capable?The Pattern This isn't just about restaurant recommendations. The same dynamic shows up across AI, therapy, cities, and education.Take AI assistants. The industry evaluates them on speed, accuracy, and satisfaction. Those metrics capture whether the tool works.

Show HN: GlossaryPage – Turn customer questions into knowledge pageshttps://glossarypage.com/Hey HN, I built GlossaryPage after noticing companies have long-tail content opportunities that never get created because they fall between blog posts and documentation.The primary use case is marketing teams building glossaries and learning hubs around these topics. The same workflow also works for support teams creating help centers.GlossaryPage helps teams identify unanswered topics, generate drafts with AI, review content, and publish structured knowledge pages.Here is a demo site: https://glossary.glossarypage.comSome things I have been thinking about while building this:1. How to avoid creating more low-quality content?This is a challenge for anyone building AI content tools, and is something I'm working on. The product is focused on generating drafts, but users are responsible for reviewing and approving what gets published. My guess is that as AI systems improve at evaluating quality, there will be less value in publishing low-quality content.2. Why not just use an existing CMSJul 24, 2026 3:44 AM

Show HN: Anakin – API for your AI agents to access the most difficult websiteshttps://anakin.ioEvery second thing I build needs to access the web, and I was frustrated with not finding something that just works all the time.With my team, we built this because I wanted to enable access to extremely difficult websites and apps for every AI agent. We have solved this cat-and-mouse problem with self-healing built in.It's one API to get data from hostile sites, and it can do easy sites too. You POST a URL and get back Markdown, JSON, HTML, a screenshot, or all of them. That same call handles anti-bot, proxy rotation, JS rendering, persistent authenticated sessions, and schema-based extraction. It gets data from most sites behind Cloudflare and Akamai, which is where other tools fail. Sometimes you need to wait for the page to load, or click on something before you get the data, and we built that in too.When we started six years ago, we could only serve large customers, because it required engineers to manually set up a scraper for every website.

Show HN: Velprium - Time Workspacehttps://www.velprium.com/Hi HN, I'm Minjae, a solo developer.- About two years ago, I came up with an idea and worked on it as a side project for about three months, but I had to quit because I was overwhelmed by my main job.However, when I recently used a coding agent to configure the specifications and have the development done, the implementation speed was incredibly faster than it was two years ago. So, I focused on refining the specifications and rode that momentum to launch the service in just two weeks.- The reason I developed Velprium was the problem of my data being scattered across multiple places when recording my day. Calendar, Notion, Obsidian, and various other collaboration tools...I even tried a paper bullet journal, but I failed every time I had to transfer notes between digital and analog formats.That led me to think, "What if I added Notion's properties to calendar events?" Traditional calendars consist of an x-axis representing time and a y-axis limited to just title and description. So I aJul 20, 2026 9:30 PM

A B2B marketing agency grew to $1.5M ARR in 6 months by betting on AIhttps://news.ycombinator.com/item?id=48980665I run GrowthSpree, a B2B SaaS marketing agency, selling into the US and Europe. Six months ago we made a bet that the agency model itself was broken for the AI era, so we tore ours down and rebuilt it. This is what we did and what actually happened. The bet: become the first truly AI-native marketing agency. Not an agency that "uses AI tools" by bolting ChatGPT onto a 2015 workflow, but one where AI is wired into how we find demand, win clients, and run delivery. We rebuilt the operating model, not just the toolbar.The context that matters: we have worked with 300+ B2B SaaS companies, but we'd been stuck between $500K and $800K ARR for two years. Plateaued. Then in the six months since the rebuild we went to $1.5M, almost entirely in the US and Europe, where we had no brand. Clients now include Datahub, PriceLabs, Hasura, Rocketlane, Proton AG, Spoke and more.What changed:1. We bet on AEO over SEO. Buyers now ask an LLM before they ask Google.

Ask HN: Does a local, Git-backed LLM "compiler" for personal notes make sense?https://news.ycombinator.com/item?id=48968447Back in 2012, my very first startup was a note-taking and document storage app. Think Evernote meets Google Drive, but with a much faster UI. We managed to claw our way up to 1,800 active users. Then Google announced 25GB of free storage for Drive, and overnight, our business model evaporated. We had to shut down the company.I've been through the startup ringer four times since then. Despite the explosion of knowledge management tools over the last decade, I still manage almost my entire life and todo list in a single Markdown file. I’ve grown to severely distrust SaaS note-taking apps. I don't want my second brain held hostage by a monthly subscription, and I don't want it locked in a proprietary database.I'm thinking about building something new in this space, completely free and open-source, and I want a sanity check to see if anyone actually cares about this approach.The Idea: A lightweight, native desktop and Mac/Windows app that acts as an "LLM compiler" for your local files (insJul 19, 2026 2:20 PM

Router ARP/NAT contradict after reload. Client ghost or firmware bug?https://news.ycombinator.com/item?id=48942957I have a Keenetic Extra DSL router. I configured a static DHCP reservation so that my ESP32-W5500 device (MAC: de:ad:be:ef:fe:01) always receives 192.168.1.114. There's a MAC-based port forwarding rule for port 80, and a defined [subdomain].keenetic.pro points to this device as well.After a soft-restart, port forwarding silently breaks for WAN traffic. The rule appears active in the panel, but incoming connections from the outside just time out.This has recurred consistently across multiple soft-reload events over several months, with a different "ghost" IP each time (.100, .101, .102).From the local network, however, I can always reach the client on its assigned static IP (.114) without any interruption. And here's the kicker: if I simply disable and re-enable the port forwarding rule from the router's interface, the problem vanishes instantly and external WAN access comes right back.The weird part: during an outage, when I look at the router's own diagnostic tools, the ARP table and Jul 17, 2026 3:06 AM
