Whiteboard (YC W26) – An open-source IDE for thoughtful software design

Hello! We’re Sid, Alex, Ketan, and Milan. We’re building Whiteboard ( https://whiteboard.dev.fast/ ), an open-source desktop app where humans and agents can architect software together in a common workspace. Here’s our repo: https://github.com/devdotfast/whiteboard . We were missing the feeling of a “whiteboard session” with another dev where you leave with a deep understanding of a system, so we built this app for ourselves.

VibeDefend by CybeDefend

VibeDefend installs on your AI coding agent (Claude Code, Cursor, Windsurf, Copilot, Codex and more) with one command. From then on the agent writes with your business rules, mined from your repo, and your security rules in its context. It scans each diff while the file is still open, and a guard refuses rm -rf, sudo or a read of your secrets before it runs. Scanners check code after the commit, this runs before the line is written. Free plan, no card.

OpenAPPA – open-source deterministic guardrails that don't break agents

23 pts

Hi Hacker News! Matvey, one of the authors, is here. While building enterprise agents, we ran into a problem: the more tools you connect to the AI, the higher the chance it will run out of control and leak sensitive data. Guardrails, in theory, should prevent this, but the situation is worrying: - Non-deterministic guardrails (LLM as a judge, auto modes, etc.) are vulnerable to prompt injections, or they lack knowledge of the data, making them inefficient (~10% data leaks on our benchmarks). - E...

Hi HN, I’m Per, founder of Scrimba (YC S20). We’ve spent the last decade teaching people how to code with an HTML-based video format.

It’s like HN, but with explainer videos instead of articles. We create them on-the-fly the first time someone clicks on a link. While there are obvious visual drawbacks of using HTML...

Ekselio – Loveable for finance workflows (local first)

Hi everyone, I am KD - Back in my college days, I dabbled with coding, learned the basics, HTML, CSS etc. but somehow I ended up in Finance which consumed the next 20 years. Then, during covid I picked up coding again, learned react, typescript, etc - even built a rudimentary site - and then came the chatgpt moment, followed by Claude etc. So, as a side project, considering that I had spent 20 years in finance and M&A I started building Ekselio, loveable for finance workflows.

PlaceCall (YC W26) – agentic API to call businesses and get things done

Hi HN, this is Yarik and Vlad from VOYGR - we are building the tools for agents and apps to engage with local businesses. It all started with our own pain point at VOYGR: calling businesses to verify if they are open. We are both from Google (Maps and Search) and even there, the merchants and venues don’t keep this info updated. So we built an API and started using it in-house. On July 4th, we were driving through Portland looking for a place to eat. Google Maps was saying “Holiday hours may var... (16 points, 4 comments).

Our driver use case was development of specialist agents with a request/response lifecycle. Think of agents that have a well establ... (8 points, 4 comments).

Viggle Turbo for Qwen-Image-2.1

6-step Qwen-Image-2.1, T2I + editing, vs-base comparison Viggle Turbo v0.2.1 — 6-step Qwen-Image-2.1 A DMD-distilled student of Qwen-Image-2.1 that generates and edits images in 6 sampling steps with no classifier-free guidance, against the teacher's 40 steps: about 5× faster. On most prompts it is hard to tell apart from the base model; small, dense text (8 steps narrows the gap) and complicated edits (multi-reference composition, face swaps, identity-preserving edits) can still fall short of it. The Comparison tab shows it side by side with the base model on the official Qwen examples. v0.2 (2026-09-23): much better sample diversity than v0.1 — intra-prompt diversity 0.93× the 40-step base...
