Deterministic renders
Chromium launched with Remotion-style flags: sRGB colors, no font hinting, identical output on every run.
Open-source · Local-first · Pixel-exact
App Store screenshots,
written in JSX.
Describe each screen once as a React component. Lshoot renders every Apple and Google format, in every language you declare, into ready-to-upload PNGs. No Figma, no cloud, no account.

// Lshoot's own App Store screenshot export default function Jsx() { return ( <LshootLayout headline="Screenshots, written in JSX" screen={<StudioMockup />} /> ); }
Real exports
Five apps. Every format.
Rendered by code, not by hand.
Straight out of exports/, iPhone 6.9″ format. Chromium at 2× DPR, downsampled with Lanczos3 by Sharp. Two games, a finance app, a wellness app, and Lshoot itself — same pipeline.
Workflow
Five steps.
One minute per app.
Screenshots live next to your code. Change a headline, re-export, ship. No design tool round-trips, no resizing by hand.
- 01
Scaffold in one command
npx lshoot my-app clones the repo, swaps the marketing landing for your own dashboard, and installs dependencies.
npx lshoot my-app - 02
Describe a project
A folder in projects/ with a config.json: name, bundleId, languages. It shows up in the dashboard instantly.
projects/my-app/config.json - 03
Write screens in JSX
One TSX file per screenshot, built from @/components/aso. Or hand an ASO brief to Claude Code and let the bundled skill write them.
screenshots/01-hero.tsx - 04
Drop in your captures
Drag simulator or emulator screenshots into the dashboard. Reference them inside a rounded phone frame with <AppMockup />.
<AppMockup src="/api/assets/my-app/home.png" /> - 05
Export, then upload
Pick screenshots, formats and languages. Puppeteer renders, Sharp downsamples. The output folder is App Store Connect and Play Console ready.

What's inside
Built for devs who ship apps.
Next.js, Tailwind, Puppeteer and Sharp. Nothing proprietary, nothing hosted. Fork it, bend it, keep it.
02
Every store format
iPhone 6.9″, 6.7″, 6.5″, 5.5″, iPad 13″ and 12.9″, Android phone, tablet 7″ and 10″. One click covers all of them.
03
Multi-language
Declare languages in config.json, ship one dictionary, get one export folder per locale.
04
Rounded phone frame
A clean bezel with no notch is the default mockup. iPhone, Android and iPad frames stay one prop away.
05
8 reference templates
Hero, Device Center, Split, Tilted 3D, Minimalist, Floating UI, Dark SaaS, Call to Action. Copy, restyle, ship.
06
Claude Code skill included
Point the bundled new-aso-project skill at a brief and get a full project scaffolded with copy and layouts.

in one command.
The CLI clones Lshoot, gives you a personal dashboard as home page and wipes the upstream history. The repo is yours from the first commit.
