24 alternatives to Open-Source Interview Platform
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…

I've long had a dislike for leetcode interviews on both sides of the coin. Project-based interviews can also be challenging because it can end up filtering out folks who don't want to spend several hours building something in their free time. I met up with a friend last year -- a very senior dev -- who had taken some time off to study leetcode exercises while preparing for FAANG interviews. It struck me that one of the key measures of whether a candidate is a fit for a team is rather synthetic. CodeRev.app is a simple, lightweight tool that helps teams evaluate candidates using code reviews.…

Hello HN! I want to share DevScreen (https://devscreen.io/). We’ve been iterating on DevScreen for a few years now with the goal of delivering an awesome interview process for both candidates and the company. We achieve this by using realistic job-based tests and allowing the candidate to use their own editor - not a whiteboard or unfamiliar online code editor. Many of the existing products in this space just bring the same old whiteboard coding puzzles to the web, without solving the core problem: those tests are not a good indicator of performance. This is a waste of time…

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 :)

Kshitij and Rahul here. We're building Playground, an open-source sandbox that lets your non-technical teams prototype directly on production codebases, without bugging you (developers) to spin up and maintain another repo. The repo is here: https://github.com/B1u3B01t/design-playground. We've been working together for six years. Last year we built an AI design agent because we thought designers were the biggest bottleneck. But we were wrong. After talking to teams, we realised designers, PMs, founders and even sales people all wanted to quickly change and explore flows…

I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.

For the past few months, I’ve been hacking together Hive: a retro-style virtual workspace for devs who love building in public. It’s a bit rough but already has some cool features: - AI-powered presence to represent you when you’re offline. - Live video streaming to showcase your work in real time. - VS Code integration to broadcast your status live. - GraphQL API for full customization and hackability (such as using your own agents) - Web3 donations to support and get support from other builders. In this demo, you can claim a desk by walking up to it and pressing E, then personalize it with…

Hello HN, I am building a devtool to understand existing codebases. The idea originates from my time at big tech as well as various attempts to get involved in open source projects. When I was in college I wanted to improve my coding skills by contributing to opensource projects. I would pickup a bug or feature request but I always found myself stuck at the very first step. I did not understood where and how to begin contributing. I once submitted a patch in firefox which was labeled "Good first issue" but that was still very handheld. The assigner told me exactly which files I need to…
