What it does
This is a tool for assessing coder's skills through testing. Users can create questions or buy them from the Marketplace. Authoring questions is a nice experience because it is a true code-editor (similar to Codepen). It also has interesting analytics like Gap Analysis due to question tagging. More tests will be coming soon to the Marketplace!
Create coding tests for assessing coder's skills.
Creating your own tests and questions is free, and you can create as many as you need. When you're ready to test someone, send them a test invite. The Pay-As-You-Go Plan only charges for the number of people who actually take your test. Monthly subscriptions are not required. Even though authoring your own tests and questions is free, you can also use our Professional Tests we've created for you. Learn more about our Pricing and Plans. Create your own tests or use ours. Then enable billing which can be canceled at any time. Create an invite-link to share with test takers or use the groups feature to create groups of test takers to invite all at once. Use the Gap Analysis report to see what…from questionable.io

ItoAug 2026 · ito.ai · ▲449I'm Evan and I made Ito.ai It's code review that actually runs your code. The result is that it finds more bugs with a smaller false positive rate. You get screenshots, videos, and run logs. I built Ito because manual verification sucks and I thought I could automate it. I've been a professional developer for 15 years and now more than ever, I'm just spending time making sure things work. I looked into all of the other agentic testing tools that click around a url you give them and frankly, they sucked. They just didn't work. I figured to be able to actually testing things you need to run…

- CACodeRev.app – Code Review as Interview2024 · coderev.app · ▲150
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.…

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
