Kittl
A small team or capable engineer can replicate the core image-generation + editor workflow in a self-hosted stack (prior art exists), but you will not match Kittl’s curated asset library, licensing, or brand reach.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Kittl alternatives, with the arithmetic →
What a replacement has to do
- Prompt → AI image/vector generation → place & edit on canvas → export high-res/vector
What it still won’t have
- Kittl’s curated premium asset library and template marketplace
- Commercial licensing arrangements and bundled premium fonts/assets
- Real-time multi-user collaboration and enterprise team features
- Wide catalogue of built-in AI model choices and internal orchestration across providers
- Marketing, community, and brand recognition (user base)
What remains hard

Runnable build prompt
Build a minimal browser-based AI design studio using Next.js + React + Typescript, Node.js backend, Postgres for metadata, and S3-compatible storage. In scope: (1) integrate a single external image-generation API (configurable provider) with per-user token accounting; (2) implement a canvas editor supporting raster placement, basic vector shapes, text, and PNG/SVG export; (3) background removal and upscaling via third-party APIs or open-source libs; (4) user auth (email) and single-seat Pro subscription gating; (5) project save/load and asset storage. Out of scope: real-time multi-user collaboration, curated marketplace, enterprise billing, and thousands-of-assets library. Include input validation, error handling, retries for API calls, basic unit tests for backend endpoints, and an end-to-end smoke test for the generation → edit → export flow.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 5 cited sources+3
- Evidence score60
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
