With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.

Open Wearables▲631Hi, I'm Bart, one of the maintainers of Open Wearables. For the past few months we've been building an open-source, self-hosted backend that normalises health and fitness data from multiple wearable providers (Garmin, Whoop, Apple Health, Samsung Health and others) into a single AI-ready REST API - and thought it was worth sharing here too :) We built this out of our own experience doing custom wearable integrations for clients, and from working with paid SaaS solutions that often lack the flexibility to customise data pipelines or debug what's actually happening under the hood.…

RankAI▲581Hey HN, we are building Rankai (https://www.rankai.ai), an AI agent that pushes SEO blogs and code fixes automatically to your site. My teammate previously scaled a product to 4M users via organic traffic and SEO. And we understood the importance of driving SEO traffic for small businesses. But after we talked to a lot of small businesses and startups, we realized that majority are not doing SEO at all. For them, learning and doing SEO weekly is too time-consuming, and no way they'd hire an agency for $4k+. So we tried to automate each step of SEO process in an agentic way using…

NovaVoice▲578Hey HN, Today I’d like to show what I’ve recently built with my 2 friends. We’ve called it Nova. The idea is to built all-purpose AI Voice Assistant, which is able to interact with mail, to-do apps, messengers and socials, task trackers, apps like UberEats, Notion and some other daily apps. How we decided to work on it: We’ve recently read YC Request for startups Summer25 and were inspired by the idea of AI Voice Assistant for Mail by YC partner Tyler Bosmeny. What we’ve got: We’ve gone a bit further than Assistant for mail only and connected Gmail, Todoist, Google Calendar, and…

Hi HN! I recently switched from a Fedora/GNOME laptop to a MacBook Air. My old setup served me well as a portable workstation, but I’ve started traveling more while working remotely and needed something with similar performance but better battery life. The main thing I missed was a simple taskbar that shows the windows in the current workspace instead of a Dock that mixes everything together. I built boringBar so I would not have to use the Dock. It shows only the windows in the current Space, lets you switch Spaces by scrolling on the bar, and adds a desktop switcher so you can jump…

I built this because I was interested in the data. Didn't fully get it to what I wanted, but thought I'd share it nonetheless. Maybe someone has better data sources they could share! Turns out live ship tracking APIs are expensive so I manually just copied the json from https://www.marinetraffic.com/en/ais/home/centerx:57.4/cente... I'll probably have an ai agent do the same thing on some cron interval, if this gets any fanfare. To actually know if the port is open without live ship tracking I found…

I built this because I wanted to see how far I could get with a voice-to-text app that used 100% local models so no data left my computer. I've been using a ton for coding and emails. Experimenting with using it as a voice interface for my other agents too. 100% open-source MIT license, would love feedback, PRs, and ideas on where to take it.

Scored 65.2% vs google's official 47.8%, and the existing top closed source model Junie CLI's 64.3%. Since there are a lot of reports of deliberate cheating on TerminalBench 2.0 lately (https://debugml.github.io/cheating-agents/), I would like to also clarify a few things 1. Absolutely no {agents/skills}.md files were inserted at any point. No cheating mechanisms whatsoever 2. The cli agent was run in leaderboard compliant way (no modification of resources or timeouts) 3. The full terminal bench run was done using the fully open source version of the agent, no…

X-Pilot▲328Hi HN, I'm Heshan, founder of X-Pilot. We're building an AI Video Generator for online courses and educational content. Unlike most text-to-video generator that render videos directly from models (which often produce random stock footage unrelated to the actual content), we take a code-first approach: generate editable code layers, let users verify/refine them, then render to video. The Problem We're Solving Most AI video generators treat "education" and "marketing" the same—they optimize for "looks good" rather than "logically accurate." When you feed a technical tutorial or course…
