Workshop
The tools beside the games · activity refreshed October 9, 2026
The games are only half of what gets built here. Behind them sits a toolchain of studio-made AI tools. They generate the art, post the dailies, run the releases and remember the lessons. This page shows the tools, the games they serve, and where the work has been happening. Each card below carries its own commit activity over the last 8 weeks (counts only; the code stays private until it ships).
The toolchain
Eight tools, one studio. Each exists because a game needed it. What each is written in, what it runs on, and how busy it's been lately.
▸ Click a teammate to see what they build.
Forge
TypeScript
Makes the studio's images, video, voice and 3D models from ten AI providers behind one front door, films real gameplay from the games, and puts new art up for review. Two older tools, Asset.io and VIDio, now live inside it.
Herald
TypeScript
Posts the studio's clips to TikTok, Instagram, YouTube and Threads from its own accounts, no third-party scheduler. LineBy's daily quote reel waits for a one-click approval, and a short brief becomes a new clip through Slidecut.
Liveboard
Go · TypeScript
Turns the studio's machines into one fleet over a private network: it knows which are awake and what each can do, starts and stops them remotely, and sends heavy jobs, like model training, to the gaming PC's graphics card.
Odin
TypeScript · Node.js
Mission control: every other tool checks in with it and gets its keys from it, and it runs the business side (App Store and Google Play releases, review status, revenue and running costs) from one dashboard.
Repetita
TypeScript
Trains small language models to voice the game characters: Claude writes in-character practice dialogue, Repetita checks it hard, and a model small enough to run on the device learns from it. First pupil: Hunt's Inspector Abberline.
Rolodex
TypeScript · React
Home of the studio's Claude Code setup: the skills, specialist agents and workflows every session runs on, kept in one versioned plugin marketplace and managed from a web console. Slidecut reads its prompts from here too.
Slidecut
TypeScript · React
A browser video studio for trailers and promos. It turns Herald's briefs into finished cuts: reads the game, plans the shots, has Forge make them, edits them on a timeline and holds each cut for a person to approve.
Vault
Rust · React
The encrypted home for everything the studio makes (art, clips, 3D models), versioned, tagged and searchable. Forge files its work here, Herald and Slidecut pick it up, and it locks away the keys Odin hands out.
The games they build
What all of that is for: two games out now, three in development.
-
Runoff
C# · UnityMaciOSAndroidA bright, cel-shaded pipe-surfing racer: stand on a thruster board through ten storm-pipe circuits, from a sunlit bowl to a glass tube in orbit and on to a main nobody has maintained in thirty years, spending one finite energy core. Pick a rider and race the other three.
-
LineBy
Swift · KotliniOSiMessageAndroidA daily quote puzzle on a custom tile-swap board: free to play, with all 315 hand-built quotes unlocked by one purchase. Make your own and share it by code, sync through iCloud, send puzzles in iMessage. No ads, no tracking; the Android version is in closed testing.
-
Hunt
C# · UnitySteamiOSA Victorian monster hunt: London, autumn 1887, one police warrant and four facts to prove about something that isn't a man, then a real-time fight on what you proved. Built in Unity from Duels' world, for Steam first, then iPhone.
-
Worldwright
C# · UnityDesktopiOSAndroidA time-travel game on a simulated history: the world has ended, so you go back into the eras of one place, find what bent its history and bend it otherwise. The simulation underneath is built; the game is played first as a text game.
-
Everywhen
SwiftiOSApple WatchAn interactive audio story on an every-other-day drop, across four genre worlds: on-device AI narration on newer iPhones, dice-driven branching, offline playback, no account. Everywhen Unlimited extends any tale in ~20-minute chapters.
Paused, not forgotten
Three games on hold while the evenings go to fewer of them. Archived, not cancelled: each page shows its game as it stood, and the journal explains why.
-
Duels
Victorian spell duels in gaslit London, 1887, cast with hand gestures. Its world lives on in Hunt.
-
Adventure
A gesture RPG with your iPhone in one hand and your Watch in the other: gather in real places, craft, and fight with your body.
-
Rockstar
A first-person rock career sim: learn to really play, book the gigs, and climb from garage band to sold-out stadiums.

The page you’re reading, and how it’s built.

0n1studios.com
JavaScript · React · Three.jsWebA WebGL intro over the animated 0n1 wordmark, then more than 180 static pages (most of them a playable archive of LineBy dailies) generated from one React chrome, with build gates that block any deploy that would regress SEO or structured data.
Recent highlights
