Can I vibecode Leonardo AI?

NOT REALLY · don't bother

A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Leonardo AI, organize local or API-backed image-generation workflows and retain parameters. The hard boundary is proprietary models, hosted gpu capacity, training tools, and asset ecosystem, plus frontier models, compute, and data.

the prompt

Build a closest honest personal substitute for Leonardo AI in an empty repository.
Use Python 3.12, FastAPI, SQLite, ComfyUI as a local worker, and a small React frontend; do not offer alternative stacks.
The core loop is: organize prompts and local or API-backed image-generation workflows, submit jobs to a user-owned model server, retain parameters, and keep outputs reproducible.
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 prompt, negative-prompt, seed, dimensions, model, and workflow controls.
Submit jobs only to the local ComfyUI endpoint configured in .env.
Record exact generation parameters and workflow JSON beside every output.
Build a searchable contact sheet with compare, favorite, annotate, and rerun actions.
Support local image-to-image and mask inputs without uploading them elsewhere.
Show estimated VRAM needs and fail clearly when a workflow or model is missing.
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.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out training a new frontier model.
Deliberately leave out copying a vendor's proprietary model or dataset.
Deliberately leave out public generation hosting and moderation.
Finish by running the tests and listing the exact commands used.

why people still pay

People still pay for Leonardo AI because the product value is the model and compute fleet, not the prompt box around it. The recurring cost buys GPU procurement, model licensing, safety filters, queueing, storage, and rapid model replacement, not just the visible interface.
