AiDesigner (NodeNestor)
A visual node-based programming platform for building AI workflows. Originally called NodeNestor, this was a full SaaS product built from September 2023 to March 2024 across 259 commits — entirely before the age of AI-assisted coding.
Users connect blocks on a drag-and-drop canvas to build AI pipelines, execute them, and share them with others. Think Unreal Engine's Blueprints, but for AI.
What it does
Node Editor — Drag, drop, and wire together blocks on an infinite canvas. Data flows through connections between inputs and outputs, with color-coded types (green for strings, orange for numbers, red for booleans, etc.).
AI Blocks — First-class blocks for LLMs (Llama 2 70B, Zephyr, Mixtral, CodeLlama), image generation (DALL-E 3), audio, and summarization, plus an OpenAI connector.
Programming Blocks — For loops, while loops, if/else, variables, math operations, string manipulation, list operations, logic gates — enough to build real programs visually.
Execution — Run programs directly in the browser with an input/output dialog. Programs can be tested in-editor or executed via API.
Workshop / Marketplace — Users could publish their programs for others to browse, use, and remix. Community-driven library of AI tools.
Full SaaS — Stripe-powered subscriptions and token purchases, user authentication with email verification and 2FA (TOTP), API access for programmatic execution.
Architecture
AiDesigner/
Client/ — Blazor WebAssembly frontend (the node editor, UI, everything visual)
Server/ — ASP.NET Core API backend (auth, Stripe, program execution proxy, data)
Shared/ — Shared models between client and server
Tech Stack
- C# / .NET 8
- Blazor WebAssembly — the entire node editor runs client-side in the browser
- ASP.NET Core — API server with Identity for auth
- SQL Server + Dapper — data layer
- Stripe — subscriptions and one-time token purchases
- Docker — containerized deployment

This project is archived and no longer maintained. It was the precursor to the NodeNestor organization.
