Show HN: Hahooh – Give AI agents the power to build their own MCP toolshttps://hahooh.xyz/downloadI built Hahooh because I was tired of writing the same boilerplate every time I wanted to give Claude or a local agent access to a new database schema or a random REST API.While there are many great MCP servers out there, they are often fragmented or require manual setup. I wanted to create a "WordPress for MCP" experience where:1. Non-authed/Public tools: You can quickly bridge a public API to an agent. 2. Agent-Centric CLI: Instead of a human configuring everything, the CLI is designed so an agent can eventually say "I need access to this DB" and (with permission) create its own bridge. 3. Security: I’m using GCP Secret Manager for credentials and bcrypt for API key hashing.The stack is Go (backend), Vue 3 (frontend), and a Go-based CLI.I’m really interested in the "agent-as-builder" paradigm. If agents can build their own tools, the engineering bottleneck for AI workflows disappears.I'd love to hear your thoughts on the security model and how you’re handling MCP server management.SiApr 28, 2026 1:45 PM

Show HN: Kompressr – One Step CDN which optimizes all your fileshttps://news.ycombinator.com/item?id=47933765In my previous organization, we went from a monolith to multiple FE & BE repos & then wanted Image Optimization, which took more than a year for us to get it right & even then it was not fully done for old images!!At first it looks like "we just need image optimization." Then the scope grows:- existing site assets need a CDN path - uploads need storage and permanent URLsI saw the pain & the thought of Kompressr was born. Kompressr is my attempt to make that pipeline boring & make things just work!There are two live paths:1. Prepend a project CDN URL to assets you already host: https://cdn.kompressr.com/PROJECT_ID/https://example.com/hero.jpg 2. Upload a file directly and get back a CDN URL: curl -X POST https://uploads.kompressr.com/api/upload \ -H "Authorization: Bearer $KOMPRESSR_API_KEY" \ -F file=@output.png The returned URL is usable immediately. If Kompressr already has an optimized version, it serves that. If not, the original goes out first while optimization runs in the backgrApr 28, 2026 12:43 PM

Show HN: Ghostty Theme Mixer (preview themes and fonts live)https://ghosttythemes.com/Quick context: I’ve been messing around with various coding tools and agents (GitHub Copilot, Lovable, Claude Code, Codex, etc.) for about 2 years. Before that I did zero development. I barely knew what GitHub was. I knew a bit of python and SQL but mostly spent my time in excel doing data analysis, sentiment analysis, and NLP. I never really thought of myself as a developer, and I’m not sure shipping this counts either. It’s the first open-source thing I’ve made, and I think might be useful to a few people so wanted to share it on here.I started using Ghostty recently and kept editing ~/.config/ghostty/config, reloading, squinting, editing again every time I wanted to try a theme. Built this over a weekend so you can preview 16 palettes and 4 fonts with a background-tint slider, then copy the config lines.One static HTML file. No build step, no tracking.Site: https://ghosttythemes.com/ Source: https://github.com/mcvalosborne/ghostty-theme-mixerHope it’s useful.Apr 28, 2026 10:47 AM

Show HN: Vaava – a baby routine tracker / logging apphttps://www.vaava.app/Vaava - it is a baby tracker / logging app. It was originally built mainly for my own use, but it is now available in both app stores. It has the same basic features that you could imagine. You can save built-in events feeding, sleep, diapers. You can also create custom events for any events you like. It has reminders, a week view, trends visualization, a 'my day' builder to help you think about the baby routines.The market for baby logging apps is already quite niche, but there is some aspects that make Vaava focus on a niche inside that niche.Core differentiators from established offering in this area for unique user experience: - Uncompromising data privacy; the tech choices and architecture was done from the start to support this. There is 0 user generated data collected to centralised servers - 0 behavioural analytics, even the anonymous technical app crash analytics are completely optional - No user account needed, no giving your email, no subscriptions - AI applied in a smart/liApr 28, 2026 4:37 AM

Ask HN: Why is Rust still hard to use as a scripting language?https://news.ycombinator.com/item?id=47925000I like Rust, but the edit-run loop still feels heavier than I’d like.Sometimes I don’t care about runtime performance. I just want to write some code, run it quickly, see what happens, and keep tweaking.I know there are things like rust-script, cargo-script, evcxr, and incremental builds, but I haven’t found a setup that feels as casual as Python/Ruby.Is this just the wrong way to think about Rust, or are people actually using it this way?Curious what setups people here use when they want Rust, but with faster feedback.Apr 27, 2026 6:00 PM

What type of code should you generate with AI?https://news.ycombinator.com/item?id=47917192I (and many people) have been thinking a lot about "what are the best tasks to do using AI." My personal framework I've been using is, you should use AI to generate code when: 1. The code is easy to validate 2. It is not important that a human understands itI find that the best thing to AI generate is something on the level of a pure function (easy to validate + not necessarily important to understand implementation as long as you understand the interface). I've tried doing things like generating whole services or applications, but those often violate rule 1 - it's hard to validate an entire application behaves "correctly" when "correctly" isn't really well defined - i.e., are there memory leaks, is it secure, is it able to be monitored, etc.I'm curious of others thoughts on this topic. The larger the task you complete using AI, the more time savings, but also the more likely that a catastrophic error exists in the generated code. A side effect of following these rules is there is not Apr 27, 2026 2:50 AM

Show HN: Friendly prediction markets to turn trips into a running tournamenthttps://bets.bernikins.com/On a trip with my friend, he introduced me to Kalshi and Polymarket and was shocked at how degenerate it was being able to bet on literally anything. So naturally I built an app ironically where we could do the same thing (with fake money) on group outings!Managed to get a prototype finished in time for our big 14-person annual ski trip and we had a blast 'betting' on things like "Will [friend that always breaks his phone] break his phone?" and "Who will win the first game of Jackbox?" Having a low-stakes running leaderboard during our trip was so fun that I decided to flesh it out and share it with others for their trips, wacky professors, etc.*How It Works*1. Create a group for your trip and give your friends the group code to join.2. Everyone starts with the same amount of Tokens/Points/Ski-bux that they can wager on each question.3. Place bets on the options that you think will win - the more bets on an option, the more it costs to pick that option.4. Anyone can propose when an outApr 27, 2026 2:06 AM
