Show HN: A free tool for non-technical folks to easily publish a website https://ift.tt/Sgt8LwJ

Show HN: A free tool for non-technical folks to easily publish a website It's easier than ever for anyone to make a website, even without paying for a drag-and-drop builder like Squarespace. But there are still too many barriers for your average non-technical person to publish a site on the web. I'd bet most people don't know there are free ways to host a website, and even if they find an explainer, technical platforms like Cloudflare and GitHub (let alone the command line) can be intimidating. So I made weejur, which is basically a super simple UI front-end for GitHub Pages. You log in with OAuth, and then you can just paste HTML or upload files to publish a website. If you don't have a GitHub account, you can sign up right in the OAuth flow. It's completely free, and you can view the source here [1]. My hope is this makes it easier for people who don't know anything about web hosting to create and share their own websites. Feel free to try it out and please share any questions/ideas/feedback!

Show HN: Ohita – a tool to simplify API key management for AI agents https://ift.tt/MmOR0Qk

Show HN: Ohita – a tool to simplify API key management for AI agents I have been trying out numerous AI agent setups to find out which one I would like to run as my personal assistant. One thing that kept constantly bothering me was dealing with API keys, especially those that need jumping through hoops to keep working. Not an uncommon sight was trying to get my agent to fetch me some data or post to X/Twitter and then it would return an error as my API key had stopped working. So I built a tool that you can give to your AI agent and with one API key it can call all of the services. The tool acts as a central auth and handles individual API's requirements like refreshing tokens, making sure rate limits are adhered, sends the correct user-agents and everything else that each API might require. At first I wanted to provide all of the users no need to setup their own API keys, but that proved to be impossible. Most API providers state in their ToS that proxying the API is prohibited. Also there was the problem with identities: if an agent posts to Reddit or X the post is from the shared account. So I decided to add a bring-your-own-key architecture where you can setup your own keys (if you want to!) but the tool still handles all the token refreshing etc. Some generous services allow pretty lenient use of their API so I included those ready out of the box, no config required to getting started! Right now I am happy using this tool myself but I wish more people used it so that I could work on improving it. Since I am a single dev there is a lot of work, I am adding new providers every day, fixing bugs and all that. But if anyone would give me their honest thoughts and tested the features I could work on improving the tool even more. There is an option to pay for the usage to cover some running costs but the free tier is more than enough to get building. https://ohita.tech/ April 22, 2026 at 04:08AM

Show HN: Aide – A customizable Android assistant (voice, choose your provider) https://ift.tt/ybnHr1B

Show HN: Aide – A customizable Android assistant (voice, choose your provider) Aide is an Android app that replaces your default digital assistant. It can register as your default assistant, so corner-swipe and power-button-hold summon it instead of the Google assistant. I wanted to do something other than Google, but ChatGPT and Claude's integration couldn't do anything on device, so I built this. Bring your own key for Claude, OpenAI, or any OpenAI-compatible endpoint (Ollama, LM Studio, vLLM). Keys are encrypted on-device; conversations go straight to your provider. Free: chat on any provider, multi-provider switching, web search + URL fetching as built-in tools, custom system prompt, markdown. Pro ($6.99 launch week, $9.99 after, one-time): voice input + streaming TTS, voice-first overlay, photo/file attachments, device actions (SMS/calendar/alarms, every intent confirmed), screen context, Home Assistant integration. https://ift.tt/xXdwbMy April 21, 2026 at 05:13PM

Show HN: Flight Risk: Can you break an AI agent? https://ift.tt/CJaF4Lp

Show HN: Flight Risk: Can you break an AI agent? I built a security game that lets you try to break an AI support agent. I work on security engineering, and it's incredibly hard to try to defend against an attack that you don't know how to perform yourself. There's also next to nowhere to improve your skills. I'd heard all about fooling AI agents with just "IGNORE ALL PREVIOUS INSTRUCTIONS", but I'd never actually put that into practice, and it turns out it's harder than you'd expect! Just like knowing basic security skills is important for all software engineers, anyone working with AI should know what prompt injection looks like, and should be thinking about how to prevent it. Flight Risk lets you practice your AI agent manipulation skills: it's got your standard prompt injection and social engineering, but more than that too, each a real vulnerability. Think you could crack it? Every engineer I've given it to has been surprised by the challenge! You can use the hints, but they affect your score ;) Give it a try, and let me know how you do! https://ift.tt/YhLr1uA April 21, 2026 at 02:28AM
