The Hallway Track
35 tracked signals on vibe-coding.
DHH reversed AI skepticism after Claude Opus 4.5, calling it the dividing line to agentic coding

Expert Python author built entire library with AI, explicitly rejecting vibe coding
“Every line of code and documentation in wrapture was written by an AI assistant working under my direction. I want to be upfront about that, and equally upfront about what it was not. This was not vibe coding, where a one-shot prompt produces a pile of generated code and the person driving hopes for the best because they lack the knowledge to judge what came back.”
Stripe acquired Metronome and is integrating usage billing into AI-driven CLI orchestration via Stripe Projects.
“the use of Stripe's CLI has exponentially increased over the course of the past five six months”

AI-accelerated coding multiplies security vulnerability surface by 10x or worse
“if everyone's shipping code at 10 times faster and the defect rate stays the same, the vulnerability rate then that doesn't that mean that the defect surface goes up by 10x?”
Databricks announced Genie App Builder, a context-aware vibe coding tool that understands a business's data and governance.
“Genie App Builder is vibe coding that understands your business.”
Emergent reached $100M ARR in six months as an AI-native no-code app-building platform from India.
“Emergent is a platform that allows anybody without any programming knowledge to be able to build software that you can actually ship uh that your users can use that you can monetize.”
Microsoft introduces Rayfin, a code-defined backend SDK/CLI that deploys to Microsoft Fabric for the agentic coding era.
“Rayfen is the back-end for this new AI coding era.”
Professional AI-assisted coding needs a new term—'agentic engineering'—distinct from casual 'vibe coding,' with verification as the core challenge.
“when you fully give into the vibes, embrace exponentials, and forget that the code even exists”
Andrew Ng says the easiest way to build software in the AI era is to prompt AI, not write code.
“The easiest way to create software in the AI era is no longer to type out code yourself. Instead, you should tell AI to do it for you.”
Lovable is pursuing continuous learning at scale so its agent learns from each mistake only once.
“We want to have a mistake happen once and then never again.”
Personal AI codegen breaks traditional cloud infrastructure, requiring fundamentally new approaches
“personal AI codegen breaks traditional cloud infrastructure”
Claude Fable 5 built a complete playable game from a 2022 tweet screenshot in one session
Google's Anti-Gravity Arcade generates fully playable games from a prompt in minutes, no code required.
“anyone, whether they were a traditional developer or not, could walk up to a laptop running Anti-Gravity with a collection of AI skills and workflows, and with just an idea for a game, have it generated entirely by AI and running on an arcade machine within minutes.”
Building production AI systems requires a four-phase framework—requirements, system design, evaluation, optimization—not just vibe coding.
“Specs are the new code. The art is in defining the product requirements, the system design, and evaluate criteria so you can be confident that your AI coding buddies are building the right thing.”
Webflow co-founder's new YC startup Ploy builds websites plus auto-runs marketing optimized for ChatGPT, Perplexity, and Claude discovery.
“help you get found by ChatGPT, help you get found by Perplexity and Claude, so that businesses can run their marketing on autopilot.”
Databricks introduces governed vibe coding to bring context and control to enterprise coding agents.
“Vibe coding needs context and control to work in the enterprise”
Engineers describe scaling real-world AI coding via autonomous agent flows that break features into parallel task waves.
“within 5 to 10 years 80% of the simple code will be uh done by AI”
Engineers at energy firm Think run autonomous, parallel multi-agent flows that break PRDs into features and tasks for AI-driven implementation.
“within 5 to 10 years 80% of the simple code will be uh done by AI”
Microsoft introduces Rayfin, a managed backend-as-a-service on Fabric to take vibe-coded prototypes safely to production.
“multiple surveys and analyses uh show that 80 to 90% of AI generated or vibe coded prototypes never become production apps”
Claude Opus 5.5 composed surprisingly competent retro game music via a custom text format
“I wonder if the ability to compose competent music is similar to the 3D graphics thing - a new capability for text models that emerged in the past few months?”
AI agents can rebuild food systems by automating tasks like pasture rotation for grass grazing.
“I use artificial intelligence agents all day long. I didn't remember any of the syntax. I don't know any specific programming language, but I'll develop something this weekend.”
Coding agents have made building native GUIs cheap enough to replace throwaway CLIs
“If you haven't tried your hand at turning one of your 500 throwaway CLIs into a native app, you're doing yourself a disservice. Go build a native UI. It'll probably change the way you think.”
Google's Kaggle ran a free AI agents course for 353,000 learners worldwide
Microsoft frames AI-built apps as a spectrum from 'slop' to 'vibes' to proper AI-augmented software engineering.
“Nobody likes AI slop. Nobody wants an AI to create applications that are not awesome.”
Google released AIventure, an open-source game teaching vibe coding and agentic workflows with the Gemma 4 open-weights model.
“you have complete flexibility in how the model is served”
Animated transition between Mercator and Equal Earth map projections created using GPT-6.
Simon Willison built a tool to detect and highlight common LLM writing clichés
“no fluff, no filler, no jargon”
Steve Sanderson demos 'Vibe OS,' a fully AI-hallucinated operating system, as a comedy bit at Build.
“It's the world's first completely hallucinated operating system.”
Cassidy Williams built a browser SQL query tool where all querying runs in pure CSS, with no database or query engine.
“There is no database and there is no query engine. It's done with pure CSS.”
Swyx demos a vibe-coded internal scheduling app for his AI Engineer conference at Microsoft Build.
“It's basically sort of a binpacking problem where we have all these open slots.”
Attendees at Google I/O share casual, personal apps they built via vibe coding.
“My accounting professor for some reason leaked all his questions, so we vibe coded a mock exam that turned out to be the actual exam.”
Microsoft Build Day 2 hosted a live vibe-coding competition to build a cloud-based collaborative markdown editor with AI.
“Is there something like Google Docs, but for markdown? I need a cloud-based collaborative markdown editor, please.”
Google built an I/O 2026 announcements quiz by vibe coding it in Google AI Studio.
