CodenQuest▲282Hello everyone, I've been working on a project called CodenQuest, a coding practice app inspired by platforms like LeetCode, but with a major twist: it's heavily gamified, similar to Duolingo. The main goal is to make coding practice more engaging, especially on mobile. Key Features: - Diverse coding questions with integrated hints and timers. - Code editor with code completion and fill in the blanks questions - Performance statistics (runtime, memory, CPU usage, and more). - Gamified elements: leagues, ranking systems, daily challenges, friends, and streak mechanisms. - Available on iOS and…

Code▲20Hey HN, Today we're launching Code, a community-driven, open-source coding agent for your terminal. It's a fork of OpenAI's codex with a focus on developer ergonomics and local control. Key features: - Browser integration – attach to your Chrome via CDP or use a built-in headless browser. You can browse pages, run the CLI in a browser session, and even take screenshots from the terminal. - Multi-agent commands – /plan, /solve and /code orchestrate multiple models (ChatGPT, Claude, Gemini) to propose and implement solutions, with consensus or race options. - Diff viewer – see…

Hello everyone, We just launched a side-project we have been building over the last couple of months -- Coderoulette is a pair programming game for developers, like a Chatroulette for hackers. We match developers in real time and give them coding challenges they have to solve doing pair programming using a collaborative IDE and video conference. You can check it out here: https://www.coderoulette.com/ We also published an article explaining how we built it. I'd love to hear your feedback.…

You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned. Made in Haskell!

I'm Varun, CEO of Exafunction, and we just released Codeium to open up access of generative AI to all developers for free. In the spirit of Show HN, we created a playground version for anyone to try this tech in the browser (click Try in Browser)! We have built scalable, low-latency ML infra for many top AI companies in the past, and we are excited to leverage that tech into a product that we, as developers, would love. We hope that you do too, and we would appreciate any feedback that this community has for us!
