Built a few projects:

- http://sfxengine.com/ $2000 MRR

- https://sparkpod.ai/ $250 MRR

- https://coderscreen.com/ $50 MRR :)

Definitely trying to focus on coderscreen since it has the most durable potential as a project.

I checked whether "using AI" pays at YC startups. It doesn't

Been building a open-source technical interview platform. Trying to keep the existing ideas of async coding assessments + live programming interviews, but want to add features for the new interview formats I see of take-home projects + AI coding agent interviews

Show HN: Open-Source Interview Platform

rogutkuba — Wed, 01 Jul 2026 17:31:28 +0000

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 your thoughts on the future of hiring in this AI era. Would you want to see an interview based on how candidates use coding agents? Would you like to see more take-home based projects instead of simpler async coding challenges?

Building Pasture (https://www.usepasture.com)

Pasture takes each signup, enriches it (title, company size, funding, tech stack, and more), and scores it 0-100 against your ICP. Alerts go to Slack with full context. You can also track which channels bring quality vs. junk over time, which has been the most useful part so far.

Hey!

I built Pasture to help marketing-led and product-led companies figure out their best growth channels and see if the signups they are driving match their desired ICP!

Would love any feedback

I run a couple projects, only one makes money at the moment:

SFX Engine: https://sfxengine.com/ - ~1.2k MRR

I launched another two and hoping to get these scaled up as well

Sparkpod.ai: https://sparkpod.ai/ - $20 MRR

Disstrack AI: https://aidisstrackgenerator.com/ - $0 MRR

Show HN: Create DJ-like transitions between any two songs

rogutkuba — Thu, 07 Aug 2025 16:32:36 +0000

I’ve been building SFX Engine, an AI audio playground, and just launched a DJ transitions feature.

You drop in two songs, and the app generates a clean, beat-matched transition, just like how a DJ would make!

Would love any feedback!

Show HN: CoderScreen, an open-source alternative to CoderPad and HackerRank

rogutkuba — Thu, 31 Jul 2025 15:35:37 +0000

Hi HN,

I built CoderScreen, the open-source platform for live coding interviews and coding assessments.

Most existing tools in this space (like CoderPad or HackerRank) feel like they’re built for enterprise sales teams, charging thousands per year for something that should be fast, simple, and developer-friendly.

Key Features:

- Real-time collaborative code environment

- Fast, sandboxed execution in 10+ languages

- Entirely open-source and self-hostable (on Cloudflare)

Coming Soon:

- Web development environments (React, Vue, etc)

- Coding assessments

- Take home projects

I’m actively looking for teams to try it out, give feedback, and help shape what comes next. If you're hiring engineers or have thoughts on what’s missing, I’d love to hear from you.

Try it: https://coderscreen.com

Give us a star: https://github.com/Coderscreen/coderscreen

Thanks, Kuba

Building a lightweight alternative to CoderPad with clean UX, transparent pricing, and fast code execution. Designed to feel like a tool devs actually want to use.

Show HN: I built a visual AI chat with branching and rich content

rogutkuba — Fri, 09 May 2025 14:56:44 +0000

I wanted to explore a fresh take on AI chat interfaces by combining a whiteboard, ChatGPT, and dynamic sources.

Why.new is a visual AI chat that lets you branch conversations into dynamic mind maps while offering follow-up questions to keep your exploration flowing. Search for and embed web articles, YouTube videos, and research PDFs directly within the app, creating a rich, interactive space for discovery. It is also fully multiplayer, allowing you to share the link and collaborate with friends in real time.
