Context

**Canva** — Template-based design suite for social posts, docs, decks, and brand assets. It currently costs $18/mo.

A prompt-to-template design generator is buildable, but Canva's value is templates, stock assets, collaboration, brand kits, print/export workflows, and distribution.

This brief describes a focused, single-operator replacement for the part of Canva 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

Generate simple social graphics from templates, edit text/images on a canvas, export PNG/PDF, and save brand colors.

Generate a constrained editing workflow with reusable templates and deterministic exports.

A responsive interface with real empty, loading, success, and error states.

Requirements

Functional

Canvas editor library.

Template assets.

File export pipeline.

Hosted app.

Data and integrations

Image generation/editing API.

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 me a small canvas design editor to replace Canva Pro. Requirements:

A local web app: Fabric.js on a canvas element with vanilla JS, and a tiny

Express server for saving and export. Script tags only, no build step.

Canvas presets: Instagram post 1080x1080, story 1080x1920, X header

1500x500, A4 poster, plus a custom-size dialog.

Editing: text using my local fonts, image upload, rectangles and lines, a

layer list with reorder, align-to-center helpers, and snap guides at the

canvas center.

A brand panel loaded from brand.json: my 4 colors and 2 fonts as one-click

swatches.

Every design serializes to designs/<name>.json and reopens exactly;

duplicate-as-template is the template system. Ship 3 starter designs.

Export PNG at 1x and 2x via Fabric's toDataURL, and PDF by printing the

canvas page with Playwright.

All files local, no accounts, no telemetry.

Out of scope: stock photos, AI image tools, and collaboration. The asset

library is what the Pro fee buys, I bring my own images.

README: how to add fonts and where designs live on disk.

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:

Template library.

Stock/licensed assets.

Magic Studio depth.

Collaboration.

Licensed content and distribution rights are not reproducible with an LLM.

Permissions, presence, and shared workflows are difficult to simplify.

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.

Prior art

Working open-source software you can read, fork, or borrow from before starting:
