I'm 15 and built ContextFlow AI — paste any YouTube URL and it generates viral Reddit posts, X threads, and LinkedIn content in seconds. Tech stack: React 19, FastAPI, Supabase, Groq (Llama 3.3 70B), Stripe. Free tier available — 5 generations/day. Would love feedback from HN.
Hi HN,I kept finding myself writing scripts or manually running prompts to do things like PR reviews, documentation generation, or issue triage on my GitHub repositories.After doing this enough times, I decided to build a small platform to automate these workflows.I recently open sourced it:https://github.com/Njuelle/CodaholiqCodaholiq lets you run AI-powered workflows triggered by GitHub events.You connect a repository and define automations that run when certain events occu
I built an autonomous AI portfolio management system that runs on $300/month infrastructure.Results: 34% returns over 3 months vs 7% S&P 500. Real capital, not backtesting.Architecture:Stage 1: LightGBM ranks 1,700+ stocks daily (80+ features) Stage 2: JAX PPO optimizes portfolio allocation Walk-forward validation, champion/challenger deployment Nightly retraining pipeline Recent additions:Personal portfolio analysis with ML health scores Daily digest with Perplexity-summarized new
Every time we want to buy something online, we go through the same ritual.Open a marketplace. Search. Scroll endless catalogs. Skip ads. Ignore “recommended” products. Compare listings that look almost identical.Eventually fatigue wins and we click something — not because we’re sure it’s the best option, but because we want to stop spending time on it.It’s strange that we’ve normalized this. Buying online often means navigating noise: catalogs, ads, rankings, and persuasion systems competing for
Hey HN! I built a thing and I'm really excited to share it.EDIT: I meant to link to the github, not the website: https://github.com/max-hq/maxLike many of us here, I've been commonly reaching for a pattern of "pull data into db; give it to claude" for a while, whilst doing data spelunking or building tooling - for the same reasons mentioned by thellimist over here [1] and a few other recent "CLI vs MCP" posts.To that end, about a month ago I star
My co-founder Tyler Brown and I have been building our product for 6 months. The co-working space that Tyler founded that we work out of houses 300 founders that we've gleaned agentic coding tips and tricks from.Neither of us came from traditional SWE backgrounds. Tyler was a film production major. I did informatics. Our codebase is a 300k line Next.js monorepo and at any given time we have 3-6 AI coding agents running in parallel across git worktrees.Every feature follows the same four-pha
CloakPipe is a small Rust proxy that sits between your application and any OpenAI-compatible API.It detects sensitive entities in requests, replaces them with consistent pseudonyms, forwards the sanitized request to the LLM provider, then rehydrates the response before returning it to your app.“Consistent” means the same input always maps to the same token (e.g. "Tata Motors" → "ORG_7"). This preserves semantic structure so embeddings and retrieval still work, while ensuring
I've been building go-tui (https://go-tui.dev), a terminal UI framework for Go inspired by the templ framework for the web (https://templ.guide/). The syntax should be familiar to templ users and is quite different from other terminal frameworks like bubbletea. Instead of imperative widget manipulation or bubbletea's elm architecture, you write HTML-like syntax and Tailwind-style classes that can intermingle with regular Go code in a new .gsx filetype. Then you
I built this because I was running Claude Code, a local LLM, and multiple dev servers simultaneously and had no visibility into what was actually happening. Activity Monitor is useless for this. htop has no context.Hydra is a macOS desktop app (Electron + React + TypeScript) that shows:- Which AI agents are running (Claude Code, Codex, Cursor, Gemini) and their status - Per-process CPU/memory with project grouping - Port-to-process mapping - Git repo health across all your projects - N

AGENTS.md (and CLAUDE.md, GEMINI.md, .cursorrules) has become the standard way to tell AI coding agents how your repo works. It's now in 60,000+ repos. Codex, Claude Code, and Gemini CLI read these files before every task.The problem: nobody keeps them up to date.Paths get renamed. npm scripts change. Framework patterns go stale. The file that was accurate when you wrote it in September starts giving your agents wrong instructions by December — without a single commit to AGENTS.md.An ETH Zu
I built this after getting frustrated with unsafe file operations in automation workflows. Key features: • Atomic writes (no partial/corrupted files) • Automatic ZIP backups before every change • Regex and AST-based text replacement • 1,050 automated tests with 100% pass rate • Dual implementation (Python + Go, Go is 20x faster) Use cases: • CI/CD pipelines that modify config files • Automated refactoring scripts • Any
I’ve been spending the last few months building Coi, a type-safe language that compiles to WebAssembly. The initial goal was just a fast, reactive web language, but as I refine the core, I’ve started mapping out how to take this multi-platform, mobile, desktop, and server, without falling into the traps that other frameworks have.The plan is to use C++ as the intermediate layer. For desktop and mobile, I want to use Skia combined with a layout library to translate HTML/CSS sizing and transf
I'm in Tehran. I woke up this morning, did some exercise, and about 3h ago i started hearing the sound of fighter jets; then heavy bombing.<p>A large-scale military operation has taken place in Iran, and one by one, communication channels are effectively being cut off by the government.<p>if you’ve seen the videos coming out of Tehran, look at how people are reacting, the way they respond when they see the bombardment. it’s striking!! yeh?<p>What do you think is going to happen?
When considering React, Angular, and Vue, the first thing to note is that they carry the same notion at their cores: data binding. The idea here is that the framework assumes the work of tying the ...

Hi HN,I recently updated my pytest plugin based on httpdbg to include the HTTP traces directly in the Allure reports. As with httpdbg, the idea is to have nothing more to do than to add an argument to your command line: --httpdbg-allure.For example:pytest examples/pytest_demo.py --alluredir=./allure-results --httpdbg-allureFor each test, all HTTP requests will be recorded and saved in the Allure report under a step named httpdbg.You can check the README in the repository to see how it
Hi HN, I’m Sandhya and we have built Visual DB — a web front end for databases. It lets you create data-entry forms, spreadsheet-like grids, and reports directly on top of your existing relational database.Here’s a quick walkthrough: https://youtu.be/4zv_HQKdKeI (13 minutes)WHAT PROBLEM IS THIS SOLVING?Building CRUD apps with master-detail forms, transactions, and proper concurrency controls typically requires weeks of custom development and ongoing maintenance.
