Cost Blame Report

Research Agent is driving most of the spend.

GPT-4o handles the longest branch and accounts for 72% of total cost. Switching that node to Claude 4 Sonnet or GPT-4o mini is the fastest savings lever.

Neurovn is an indie, open-source workflow canvas focused on making AI system cost and latency visible before teams ship.

Agentic AI is booming.
But nobody knows what it costs.

Millions of multi-agent workflows ship every day across GPT-4o, Claude, Gemini, and dozens more models. Understanding the real cost, latency, and bottlenecks? Still guesswork. Teams deploy blind — and deal with surprise bills after.

Neurovn fixes all of this. Here's how ↓

How it works

Three steps. Click any stage to inspect it.

Step 01

Design

Auto-cycling

Place the core nodes on the canvas and sketch the flow in seconds.

StartAgentToolFinish
Build the graph first, then refine the details.

Visual Orchestration

Design your entire workflow. Visually.

Drag Start, Agent, Tool, and Finish nodes onto an infinite canvas. Connect them to define data flow, assign models, and see the full graph — no code required.

Token & Cost Estimation

See exactly what it costs. Before you ship.

Our engine uses real-time provider pricing and optimized token logic to calculate exact counts, costs, and latency for every node in your graph — in under 10ms.

Summary

Codebase Integration

Visual-first, code-connected workflows.

Neurovn combines a visual orchestration layer with direct codebase instrumentation. Decorator-first traces and CLI ingestion stay transferable to the same editable canvas, with high-fidelity token and latency estimation powered by Rust-backed tiktoken tokenization.

Code + Canvas, Unified

Neurovn gives you a visualization layer and direct codebase integration in one workflow.

Instrument existing services with lightweight decorators or CLI ingestion, then transfer everything into the same editable canvas.

Rust-backed tokenization via tiktoken powers high-fidelity token and latency estimation from real execution paths.

Instrument

Add CLI trace commands or Python decorators in your existing codebase.

Transfer

Neurovn converts runtime traces into a clean, editable workflow canvas.

Optimize

Refine costs, latency, and structure visually without losing code context.
