The stack

The React app edits workflows and displays streamed execution. A Fastify API validates requests, manages account and workflow state, and connects the app to model inference, Compose and NEAR.

Component	Responsibility
React, TypeScript and Vite	App rendering and local development/build tooling
React Flow	Canvas nodes, edges, handles, viewport and graph interaction
AG Grid / AG Charts Community	Creator workflow tables, activity and charts
Fastify / Zod	HTTP routes, request validation, access checks and NDJSON streams
Compose SDK	Catalog discovery, coordinator execution, resource calls, sessions, metering and payment settlement
Nebius chat completions	Vibe’s tool-driven graph building
Google image generation	Avatars and workflow banners
Neon / Drizzle	Durable relational account, workflow and run records
Valkey / ioredis	Shared caches and frequently updated composer state
Pinata / IPFS	Addressed media files, workflow cards and proof bundles
NEAR APIs and Intents SDKs	Universal Account provisioning, relayed calls and cross-chain routes
Cloud Run	Containerized Node.js API hosting and HTTP concurrency

Inference runs through hosted services and the resources selected in the catalog. Performance covers streaming, caching and concurrency; NEAR covers the account and contract layer.
