Deep Dive: Switching from Leonardo AI to NodeTool
Trade-offs, installation & data architecture
What you trade away
It retains local workflows and results, but the user supplies compute and providers and gets no Leonardo-style shared asset catalog or managed training.
How to deploy NodeTool
Install the macOS .dmg, signed Windows .exe, or Linux AppImage; Docker Compose is available for self-hosting
What it takes to run
No useful model or provider is bundled: the user must add an API key or download a multi-gigabyte local model, and some local backends add a large Python/Conda environment
Where your data lives
Workflows, projects, assets, files, provider settings, and vector indexes live locally in YAML, SQLite/SQLite-vec, and application storage; optional S3 or Supabase storage is supported, and cloud nodes transmit their inputs
Why fork NodeTool instead of vibe-coding a Leonardo AI clone?
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.
