Can Snappa be vibe coded?
Compose fixed-size social graphics from local images, text, and a small template set
The core loop is small enough for a capable coding agent to produce a useful local version. For Snappa, compose fixed-size social graphics from local images, text, and a small template set. The hard boundary is stock-photo allowance, templates, team sharing, and cloud convenience, plus editor polish, assets, collaboration, and distribution.

The achievable core
- Compose fixed-size social graphics on a canvas from local images, text, and a small set of reusable templates, then export a polished SVG or PDF.
- Generate a constrained editing workflow with reusable templates and deterministic exports.
- A responsive interface with real empty, loading, success, and error states.
The parts a prompt cannot buy
- stock-photo allowance, templates, team sharing, and cloud convenience
- huge template and asset libraries
- real-time multiplayer
- brand governance
- The last 20 percent is sync, migration fidelity, speed, and edge cases.
- Licensed content and distribution rights are not reproducible with an LLM.
Why people still pay
People still pay for Snappa because people pay for a vast ready-made design system and a collaboration surface that behaves predictably under deadline. The recurring cost buys canvas correctness, fonts, exports, templates, asset rights, multiplayer state, and accessibility, not just the visible interface.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
Licensed content and distribution rights are not reproducible with an LLM.

Build brief — a focused alternative to Snappa
Context
**Snappa** — Compose fixed-size social graphics from local images, text, and a small template set. It currently costs $15/mo.
The core loop is small enough for a capable coding agent to produce a useful local version. For Snappa, compose fixed-size social graphics from local images, text, and a small template set. The hard boundary is stock-photo allowance, templates, team sharing, and cloud convenience, plus editor polish, assets, collaboration, and distribution.
This brief describes a focused, single-operator replacement for the part of Snappa that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.
What you are building
Compose fixed-size social graphics on a canvas from local images, text, and a small set of reusable templates, then export a polished SVG or PDF.
Generate a constrained editing workflow with reusable templates and deterministic exports.
A responsive interface with real empty, loading, success, and error states.
Requirements
Functional
Modern desktop browser.
Local fonts and images.
Data and integrations
Optional image-generation API key.
Each of these needs a real account, credential, or quota. Set them up before writing feature code.
Non-functional
Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.
Security: server-side secrets, validated input, and no credentials in the client bundle.
Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.
Portability: the operator can export their data and leave without losing it.
Implementation brief
Build a personal replacement for Snappa in an empty repository.
Use Next.js 15, TypeScript, React, Tailwind CSS, IndexedDB, and SVG; do not offer alternative stacks.
The core loop is: compose fixed-size social graphics on a canvas from local images, text, and a small set of reusable templates, then export a polished SVG or PDF.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create a fixed-size SVG canvas with zoom, pan, selection, alignment, and snapping.
Support text, rectangles, circles, images, groups, layers, and reusable components.
Add a small set of high-quality starter layouts relevant to the product category.
Implement undo, redo, autosave, and import or export of a portable project JSON file.
Export SVG and print-ready PDF without rasterizing text unnecessarily.
Keep all assets local and display missing-font warnings before export.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out real-time multiplayer editing.
Deliberately leave out a commercial stock-asset library.
Deliberately leave out enterprise brand controls and approval workflows.
Finish by running the tests and listing the exact commands used.
Delivery standard
Inspect the repository first, then write a short implementation plan before writing code.
Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.
Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.
Include responsive layouts plus genuine empty, loading, success, validation, and failure states.
Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.
Add structured logs around every external call and return actionable errors without leaking sensitive details.
Write unit tests for the core logic and one automated test of the main user journey.
Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.
Acceptance criteria
A clean install starts the app using only the README and .env.example.
The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.
Invalid input, missing configuration, provider failure, and an empty database each have a usable state.
The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.
Tests, type checking, linting, and a production build all pass with no ignored failures.
No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.
Non-goals
Do not build these, and do not claim to have replaced them:
Stock-photo allowance, templates, team sharing, and cloud convenience.
Huge template and asset libraries.
Real-time multiplayer.
Brand governance.
The last 20 percent is sync, migration fidelity, speed, and edge cases.
Licensed content and distribution rights are not reproducible with an LLM.
What you still own after launch
Secure credentials, rotate secrets, and handle provider rate limits.
Run migrations, backups, restores, and dependency updates.
Test the critical journey after every model, API, or hosting change.
Monitor failures and fix the edge cases a first prompt will miss.
Risk
**Manageable.** A personal version is realistic if you test the critical journey and keep reliable backups.
Editorial confidence in this assessment: high. No independent one-shot implementation is linked yet.
