App-building workflows

Peter Yang says Fable 5.2 built his browser kart racer in three prompts, with drifting, items and multiplayer. He later added Suno music and turned his child's drawings into racers.

Amir Mushich shared public code repositories for 10 creative projects. Examples include a JavaScript game engine, photo-to-3D spaces, video-driven interfaces and a reference-based brand skill.

Hasantoxr shared tests in which Tencent Hy4 turns sketches into games or HTML pages and app screenshots into code. The thread includes WorkBuddy access steps, API pricing and a November 15 cutoff for the limited free quota.

MengTo says his three.js turn-based game used $10,000 in tokens over more than a month with Opus 5.5. He used Tripo for characters and Supabase for saved state, and cited rigging problems and a browser download exceeding 100 MB.

Andrej Karpathy says he used Claude to build HackerTube, a collection of 6,454 video picks extracted from 43 million Hacker News comments, in about two hours. URL filters, regexes and spam removal reduced the material before Sonnet reviewed the remaining comments.

Charlota’s Hue Scream maps vowels, pitch and volume to colour. The remixable project documents a Figma MCP-connected prototype, canvas revisions and agent-directed motion.

MengTo built eight landing pages for about $12 in tokens using screenshots and revision prompts. The workflow used Nano Banana photos and Claude Code fixes; five of 24 first deliveries needed no repairs.

AIandDesign shared a downloadable Canyon Overdrive build that reportedly reaches nearly locked 30fps after days of Astra-assisted optimization. Development uses FlyCast; an earlier build ran on real hardware, but validation of the newer build is still pending.

Runway App Studio lets users build image, video and audio apps from descriptions with its models and Brand Kits. Launch demos include character swaps, annotated edits and product shoots.

Danny Limanseta says he built an Unreal prototype through Claude Code and the CLI, using C++ and Fab assets. An Opus-generated batch launcher let him preview the game without opening Unreal's editor.

MengTo built landing pages with MiniMax M3.1 Flash, using images to set visual direction before coding. Shared references, reusable skills and screenshot reviews guided revisions.

Figma launched Code Layers in open beta, bringing code onto the Figma canvas. Its Chrome extension can capture website code as a Code Layer.

Linus Ekenstam presents IMPULSE, a Rust physics engine running through WebAssembly with a WebGL2 renderer. He reports an 83KB binary handling 20,000 bodies at 120fps on an M5 MacBook Pro.

Anthropic released Haiku 5.5 with a reported tenfold price reduction for requests below 100,000 tokens. Aakash Gupta cites $0.10 input and $0.50 output per million tokens and a 72.4% OSWorld score; Viktor Oddy demonstrates the model on website design.

Kitze launched Flavors with copy-paste landing-page references, design Markdown, shadcn components and templates. Most resources are free; a launch-week $99 lifetime Pro plan adds API/MCP access and other assets.

Danny Limanseta shared a playable desktop-browser parcel delivery game built mainly with Sonnet in Three.js. His development posts explain the model choice and discuss trailer revisions and a shader issue in the rainy, Hong Kong-inspired project.

A creator used Claude Opus 5.5 to build Fallout: New York, a browser game with quests, dialogue trees and a Pip-Boy. The creator reports a five-day build with visuals and sound generated in code; play currently requires a desktop.

A Framer creator converts a completed page into a Skill containing its type, colors, spacing, components, and visual direction. Additional Skills can then add effects, voice, and page-specific details without restating the base system.

Creators prompted Claude Opus 5.5 to build 3D scenes in code, score individual visual elements, and revise them iteratively. Reported outputs include a Three.js ship scene and an explorable Atlantis world built in about two hours.

Higgsfield demos show Claude Opus 5.5 producing explorable anatomy interfaces, a hand-drawn chess game, and continuously animated visual scenes through code. The examples present visual elements and timing as editable output rather than fixed rendered clips.

The publisher says generic AI image tools could not reliably follow its charts, colors, and brand details. Its custom code-based generator turns data into branded graphics and has produced dozens of reusable layouts.

Designer Tran Mau Tri Tam documented a workflow using Framer's AI design agent to build and publish a brand site. The process starts with a wireframe and prepared content file, then uses the agent to handle responsive breakpoints.

Meng To says he built a free, mobile-friendly multiplayer Catan-inspired game with GPT-6 Astra in four days. He reports spending hundreds of dollars in tokens on narration, guides, expansions, and voice-chat lobbies.

Higgsfield and creators demoed GPT-6 Astra game prototypes spanning branching stories, a Unity fighting game, an Unreal shooter, and a Three.js project. One maker paused a Catan-like game because it was too close to the original to release.

Reported GPT-6 Astra projects include a Roblox dragon world, a prompt-responsive Minecraft screen, a first-person motion simulator, and several Three.js games. An Astra-made Mac and Windows game also added saved progress and revised controls.

Users are publishing Fable 5.1 browser worlds including game clones, shader-driven scenes, a train yard, and a procedural Kyoto three.js site. One reported racing-game test cost $123.98 and used 1.2 million tokens, exceeding Fable 5.

Runway introduced Solaris, an Interface World Model that generates interactive interfaces frame by frame without code. The research is not yet publicly available.

A Base44 user reports that a one-paragraph prompt produced a live CRM with authentication, persistent data, and a custom domain. They later added email follow-up reminders through another prompt.

A Tembo user demonstrated real-time frontend iteration in cloud Linux VMs with databases in the same environment. Apps can be tunneled from a VM and shared by link, while nested virtualization is being added.

The MIT-licensed service says 58 builders with 56 sites are trading contextual links through coding agents. It gives an agent a partner brief, then checks whether the agreed link was published after repository edits.

A creator reports that OJO used supplied references to create a product strategy, wireframe, and editable responsive fintech landing page from one prompt. The prototype included live site sections and could sync to Figma.

A creator outlines a workflow that generates one image keyframe per web section, then animates them with Seedance 2.5 as a continuous camera journey. Foreground smoke or clouds hide transitions between scenes.

Anthropic’s early /design preview creates shareable, editable Artifact artboards from a codebase. Creators can select an artboard before carrying the design into implementation.

Danny Limanseta says Grok 4.6 produced most of a WebGPU horde shooter, including its UI, visual effects, and sound effects. Meshy generated and rigged the character models separately.

Developers described brittle AI app workflows, including one CSS-to-Tailwind refactor that had to be resumed five times. The complaints focused on debugging, local setup, and project inventory.

Meng To released the Kage landing page repo and reusable Three.js skills after building the 3D scrolling site with Claude Code, Opus 5, and image tools. He cites a 922 KB build and mobile fixes.

Practitioners said coding agents can make impressive game demos quickly, but playable games still require weeks or months of design, testing, and cleanup. Other posts pointed to limited visual reasoning, 3D topology fixes, and Fable or Opus model choices as current bottlenecks or workarounds.

Practitioners are putting review steps around AI app builders before merge or publish. Examples include PostHog-to-Cursor Cloud PRs, Bolt's six-category security scan, and a Claude Code prompt that inspects repos first.

Pieter Levels summarized Fireship’s claim that cheap coding agents make micro-SaaS execution easier to copy. Replies argued distribution, complexity, and non-code moats still matter.

Levelsio pointed to open-source clones of Wispr Flow, Granola, and WHOOP as evidence that software creation is getting cheaper. Builders replied that AI apps face far more competitors and need ads, attention, or an existing audience.

Peter Yang published a 25-minute tutorial and written workflow that moves from problem definition and Claude Design prototypes to reusable design-md files and Claude Code implementation. The process adds Mobbin research and HTML specs so agents can reuse design context instead of rebuilding UI direction each prompt.

New Opus 5, Codex, and Fable demos showed agents creating 3D worlds, Blender assets, Godot ports, and one-shot games. Pushback focused on whether the clips become games worth playing.

Shared resources included design-skills repos, a UI visual dictionary, CRM table tokens, and Claude Opus 5 website prompts. The reusable context can speed front-end generation but does not replace product-specific design choices.

Creators posted demos where Opus 5 built browser 3D games, Codex Sites produced a Three.js game, and Grok 4.5 helped redesign a Steam card game. Some workflows now pair video concepts with Claude Code, but the evidence is demo-based.

Bolt.new and related AI frontend workflows let teams store brand rules or design-system skills once instead of pasting them into every prompt. Taste Skill was cited with 67,000 GitHub stars after heavy Codex use.

Levelsio pointed to customers and founders replacing paid apps with private AI-built versions. The debate centers on whether AI raises quality baselines while weakening pricing power for simple software.

A demo roundup showed Grok 4.5 generating game engines, worlds, controllers, CAD objects, React projects, and voxel scenes. The clearest consequence was faster playable prototyping by a single operator.

Omoore says ChatGPT Sites built a playable “chronically online” quiz game with images, interactive modules, levels, and an anonymized dashboard. Only 4% of tracked players reached the top tier.

Nick Launches said the product outgrew its rushed May backend at 21k users and moved to a cleaner NextJS setup using dirstarter, better-auth, and oRPC. Week 11 updates listed 85 live launches and new directory filters, making it a concrete post-MVP refactor case rather than a launch demo.

Creators built hosted ChatGPT Sites from prompts, including a GeoGuessr-style game with ChatGPT auth, secure key storage, Google Maps keys, OpenRouter opponents, and budget limits. Another site used ChatGPT Images for a math game UI.
