Alternatives
Products that do what Leetcode but for front end devs (terrible idea?) does
Howdy friends! Tell me if this is an atrociously terrible idea - I've been working on building a leetcode for clientside devs so we can practice React and Javascript interview questions in a more concise way, I call it clientside.dev I just finished a beta version of it yesterday and plan on releasing it with many more problems on Jan 1st but it's there if you wanna play with it open to any ideas / feedback however mean or nice it may be :)

Hi HN, After watching a lot of Show HN's here, it's finally my turn to show something. This is the first real project I have shipped, so it is extra special to me. For those who will inevitably ask why I made yet another mockup editor I covered it on our blog (http://blog.mocktailsapp.in/why-build-yet-another-mockup-editor-tm). Not all the features mentioned in that post have been implemented yet. As such Mocktails is pre-beta software and very minimal. It does not even have user accounts or any actual server side component at all for that matter (yet)! Our intention is to build Mocktails…

Hello HN! I've been working on http://underthesite.com for the last month and now think it is ready for some full strength HN feedback. What do you guys think? It crawls up to 10 pages of a given site while you wait, looking for community-provided CSS / XPath selectors and regular expressions. Additionally, I'd like to appeal to you to submit matchers for technologies that you care about. Technologies are easy to add, so add your favorite jQuery plugins, analytics tools, client-side node.js wrappers, what have you. I'm going to be running a large crawl in the next few days and want to make…

Hey HN! I've been working on Muxamp for over a year now, and I decided that there's no point in keeping the source closed. (I never planned on making money from it.) I've learned a lot since I started, and I hope others can benefit from its release--and perhaps teach me a thing or two as well :)

We got tired of not being able to accurately answer "When will this be done?" and "Will anyone be required to work overtime on the current schedule?", or spending too much time in meetings and standups trying to answer those questions. Just opened up for beta. Would love some opinionated developers to guide future improvements (or feedback on the general idea).

hi! I’m a 17 y/o dev and I made this so I could show my wpm in code rather than just normal text :) this was my first project that I made awhile back but wanted to share it today. I used React and got the LeetCode samples by webscraping a site that had all the solutions. you can read more about the site in the "about" page. here's the repo: https://github.com/max-lee-dev/hackertype https://twitter.com/maxleedev

I created http://devtest.net as a weekend project, and I'm pretty proud of it from a technical and UI standpoint. The problem is, I've built this by myself in a bit of a vacuum, to "scratch my own itch", and I don't know if this is useful to anyone other than me. I'm also not so hot on the business side and don't really know what I'm doing. Basically, I'm looking for some advice, now that I've actually launched, what now? One thing that this has shown me is that I'm capable of putting together a pretty decent web application on my own in my spare time. Should I stick with this idea, or…

This is a two man team and we're in full-on development of a new platform to assist in multiplayer games. We're looking to launch in about a month or two with an OpenID server accessible to customers (or they can use provider like Facebook/Twitter) and a couple cool multiplayer features. After we launch development will continue until we have a well-rounded API. We're primarily targeting HTML5+JS developers but the system will work with any language that can make RESTful API calls. We know there's some stiff competition out there but we're looking for feedback and what features may make…

The main goal of this was to be able to not just run multiple Claude Code sessions at once, but actually manage them and keep track of what I was doing. Sometimes this is multiple attempts on the same task, sometimes I work several tasks at once. Really I was just sick of twiddling my thumbs waiting for the coding agent to finish, and I wanted it to be easy to work on/review/test another change while I waited.

Hey! I have been building CoderScreen, an alternative to coding interview platforms. I thought it was an interesting product to build with the evolution with all the sandbox products coming our for code execution, as well as me never being satisfied with existing platforms. The current features are: - Live interviews for pair programming exercises - Assessments for async technical screening It is built on Cloudflare primitives such as Workers, Durable Objects for the multiplayer experience, Sandbox for the code execution. Would love to get feedback on the current product, as well as hear…

Hey Hacker News, For the last 2 months, I've been working on a testing agent to free developers from the endless maintenance of end-to-end tests. You just push up a PR, and our agent analyzes the code changes and automatically visits the preview to test things out like a real human! We also support describing tests in English (or even in the PR description), and we'll go through your site whenever you want via a GitHub action to test and make sure various core flows continue to work as expected. We are looking for early testers and are giving out a generous free tier! Just sign up on the…

Hi HN! Solo developer here. 10 days ago, I started building this after spending countless hours copying/pasting marketing sections and fighting to keep them consistent with our design system. I wondered: "What if AI could understand our design system and generate React components that actually match it?" Current progress (10 days in): - Can generate hero sections that follow your design tokens - Uses your actual component variants and styles - Works with Next.js, Tailwind, shadcn/ui It's very early days, but I'm excited to share it with other devs who: - Are tired of rebuilding…

I started an experimental series, "console.solve", on mini javascript challenges a few months back and received good feedbacks on it. So I created a [second one](https://colintoh.com/console-solve/issue-2?utm_source=colint...) this month. Not sure anyone here will be interested as it's not exactly pro-level stuff. But if you have an hour to spare, it can be a good distraction. For those who are interested, here was the [first challenge](https://colintoh.com/console-solve/issue-1?utm_source=colint...).

Hi HN, A lot of the dev teams I have worked with had a lot of issues with their documentation. In fact, some of my easiest clients to get were from clients that had "black box" solutions that devs no longer at the company had created. Personally, writing documentation is like grinding nails on a chalkboard. I have been having a lot of fun with building solutions that can run in a distributed way, not something a dev needs to run themselves. And after a significant amount of testing and building out several different solutions, I finally have a solution that is easy to set up and runs in the…

Hey everyone, my friend and I created a GitHub Wrapped video for developers to showcase their activity on the platform in a more fun way. The implementation is open-source (https://github.com/rendleyhq/github-wrapped-2024) if you're interested in how it was built. To get a bit geeky, we used masks, keyframe animations, luma key shaders to remove the background from the confetti video, and some other techniques. Also, everything is rendered directly in the browser!! I'm curious to hear your thoughts on the rendering performance, especially if you're running this on your…

Hi Hn, A buddy and I worked on this prototype to see if we could design a system that helps people think creatively. I'd love your feedback, tips and pointers - and yes, I know it's a bit ugly (much css work to be done). Check it out at beta.monsterlumen.com and let us know what you think!

I've been specializing in UI for over a decade. Using code for UI is great but I always wished there was a more visual code to build apps and sites. So I went ahead and built it. Decided to build it with Compose Multiplatform since I work a lot with Kotlin. Currently exports to CMP as it was simpler due to the context switch. You can try it for free and export some apps

Hey HN! I built Algochurn - A place for front-end developers to practice most commonly asked front-end interview questions. Of all the available resources out there, I wanted to have a place where I could practice coding questions myself (and to mimic a coding interview setup) and solve the problems with a time based approach. After 2 months of questions curation, I've come up with the first set of questions that are being asked in Big product based companies that assess candidates on their React skills. Use Algochurn to speed up your interview preparation. Save and Bookmark questions, Mark…

I’ve spent the last 2.5 months building a product that runs LLM-powered code reviews on my pull requests — and I just launched it. The tool is built specifically for solo developers. You install it on your repo, trigger a scan by creating a pull request, and it leaves structured review comments using OpenAI under the hood. Funnily enough, I used the dev version of this app to review its own pull requests while building it. It helped me spot bugs, simplify structure, and keep quality high — all with minimal need for another human in the loop. Things I want to try out in the next months : -…

Hey HN — we’re University of Waterloo grads, and we’re building LeetPro (https://tryleetpro.com). LeetPro is Leetcode but for soft skill-based questions and cases. In other words a platform designed to help you nail behavioral, product, and case-based interviews just like Leetcode does for technical interviews. We’re combining AI-driven mock interviews with community-driven content to create a comprehensive preparation tool for systems design, product, and business interviews. We came up with this idea just last week, and we've already launched an MVP that’s worth checking out if…

Hi HN, I build this a few months back, thinking about improving it but wanted to share as is first to see what feedback I can get. I built it to be modular and with a clean understandable codebase in mind so easily extendable. I want to add more components to it maybe... Thanks! Will add link to the repo in a comment now

Fully leaned into vibe coding this time around. Started on v0, at some point ejected into running locally (getting v0's exported folder to run locally was a challenge), then iterated with Cursor over the course of a few hours. Really neat how much can be accomplished just conversationally these days.
