The frontend is where your app feels real. It's what your users see, touch, and judge in the first 3 seconds. Whether you're jamming on a new MVP or tightening the polish on your production UI, one thing's clear: clean layout, motion, branding, and visual clarity matter. A lot.

But here’s the thing - that work takes time. And most indie devs or startup teams don’t have the luxury of a full-time designer, animator, or frontend engineer. That’s why we built the Frontend & Mobile UI Builder Toolkit for vibe coders like you.

These custom GPTs are here to help you design, animate, and brand faster - all while staying locked into your creative coding flow. Whether you're already building on SashiDo, or just getting started, this suite will make your frontend look hot with less grind.

What Is It?

SashiDo's Frontend Toolkit is a collection of GPTs that:

• Generate responsive layouts from simple prompts
• Suggest smart color palettes based on your vibe
• Write native mobile animations in SwiftUI / UIKit / Android XML
• Help you plan app features, screens & data models
• Create full iOS + Android icon packs from one logo

In short: UI work goes from "ugh" to done-in-minutes.

All GPTs are optimized to pair perfectly with SashiDo, giving you a superfast route from prompt → UI → deployable SashiDo-powered app.

Mobile App Feature Planner

Before you even start building UI, lock down the plan. No more guessing what screens or data models you need. Drop in your app idea, and this GPT maps out:

• Use case and audience
• Feature list (prioritized for MVP)
• Screen map (Home, Profile, Feed, etc.)
• Parse Class models (with field types + JSON samples)

Perfect for indie hackers, hackathon squads, and devs who want to build smart and ship faster.

This GPT is built specifically for SashiDo apps:

• Uses default Parse Server / MongoDB / Node.js versions on SashiDo
• Suggests code in standard Parse SDK format
• Includes early security warnings

CSS Layout Builder

Just say it: "Header with logo, sticky sidebar on the left, grid of cards in the center, and footer."

You get:

• Semantic HTML5
• Mobile-first Flexbox or CSS Grid
• Copy-paste clean code
• Tailwind-ready version (if you want it)
• Accessibility hints baked in

Perfect for dashboards, auth pages, admin panels, and landing pages.

Want to make it dynamic? Use SashiDo to wire up Parse objects and build full-stack apps with auth, queries, and real-time updates.

Color Palette Suggestion Tool

Just give it a base color (hex or vibe like “deep space purple”) and a style (“pastel”, “dark mode”, “material”), and this GPT will serve up a full palette that looks amazing and keeps accessibility in check.

Start with: "Midnight blue, soft pastels, dark mode."

Get:

• A 5–7 color palette (primary, secondary, accent, neutrals)
• Emojis + hex previews
• Tailwind config or CSS variables (on demand)
• Light + dark mode support
• Contrast-safe combos

Great for defining your app's vibe fast - even if you don’t speak "designer."

Building for the web or mobile? SashiDo supports both - launch your app backend and integrate your palette instantly.

Mobile Animations Generator

Animations don’t have to be a pain. This GPT turns simple descriptions into SwiftUI, UIKit, or Android XML snippets that add real polish to your UI.

Ask for:

• “Slide-in card with bounce on load”
• “Fade in list on scroll”
• “Button pulse on tap”

Get:

• Copy-paste animation code
• Native style for your target platform
• UX that feels legit, not janky

Enhance onboarding, transitions, taps, and scrolls with smooth animations. You can also connect them to your app logic using Cloud Code to trigger effects based on user actions or events.

App Icon Generator Assistant

Your icon is the first thing people see. This GPT helps you prep high-res, platform-compliant app icons from a single image or logo.

You get:

• iOS and Android icon size breakdowns
• Naming conventions & folder structure
• ZIP-ready checklist
• Online tools, CLI tips, or manual guides (you choose your weapon)

Designer not around? No problem. This GPT gets you launch-ready assets fast.

Upload icons to SashiDo file storage and use them across your app with public URLs.
