>log in to commentUnlike most diagram tools that store everything in the cloud, Visual Nerve runs locally in your browser with no account or mandatory backend. It lets you turn processes, data, or code into interactive diagrams you can explore and simulate right there. I built it to help people see connections and test changes instantly. Any thoughts on the workflow?
- Editable flowcharts, mind maps and system diagrams
- Local‑first workspace stored in browser IndexedDB
- Process simulation with queue metrics
- No account or mandatory backend required
- AES‑256‑GCM encrypted encrypted workspace
Visual Nerve is a local-first browser workspace for creating editable diagrams, data/code analysis, and process simulations.
- for
- Developers, analysts, and product teams who need visual, offline modeling of systems and data.
- pricing
- free
Key features
- Editable diagrams & mind maps — Create and edit flowcharts, UML, BPMN, DFD, and other notations directly in the browser.
- Data & code import — Import CSV, SQL, JSON, or ZIP projects in 50+ languages and visualize structures with source evidence.
- Process simulation engine — Model queues, capacity, and economics; run what-if scenarios with real-time metrics.
- Realtime collaboration — Invite participants as owners, editors, or viewers with MLS-encrypted messaging.
- 2D/3D view switching — Toggle between flat and 3D perspectives while preserving layout and editability.
- Local API & MCP bridge — Expose the workspace to AI agents or external tools via a secure local API.
- AES-256-GCM browser storage — All data is saved locally and encrypted, with optional password protection.
- Multiple notation libraries — Support for HIPO, classic DFD, UML (14 families), and BPMN with built-in validation.
Use cases
- Map a microservice architecture and simulate API load to identify bottlenecks.
- Import sales CSV data, group by region, and explore churn trends with time-series signals.
- Visualize a legacy codebase, trace dependencies, and annotate refactoring plans.
- Collaboratively design a business process flow and test capacity changes with stakeholders.

- Visual Nerve vs ArchFormation: Focuses on cloud-native diagramming for architecture, not local-only simulation.
- Visual Nerve vs Schema Visualizer: Visualizes data schemas and APIs but lacks process simulation and local collaboration.
- Visual Nerve vs Dim0: Provides a free-form canvas without built-in data import, simulation, or encryption features.
- Visual Nerve vs Ideon: Offers big-picture project mapping but does not support editable code/data imports or simulations.
Visual Nerve FAQ
Do I need to create an account to use Visual Nerve?+
No, the tool runs entirely in your browser with no account or mandatory backend.
Where is my data stored?+
All diagrams and imported data are saved locally in the browser and encrypted with AES-256-GCM.
Can multiple people work on the same diagram?+
Yes, you can invite others as owners, editors, or viewers; collaboration uses MLS-encrypted messages.
Is there a limit on the size of imported data?+
Current limits are 200,000 rows per source and 600 generated objects per view; other file-size limits apply.
How can I connect an AI agent to my workspace?+
Enable the optional local API/MCP bridge; the agent must have an approved participant role and explicit write grant.
Does Visual Nerve require an internet connection?+
Only to load the app; all modeling, storage, and simulation run locally without a backend.
