ProtocolDiagram.io - Declarative Binary Format Renderer

A web-based editor where engineers paste or upload a structured protocol definition (JSON, YAML, or custom DSL) and instantly generate RFC 7748-style packet diagrams with proper bit offsets, field alignment, and byte boundaries. Outputs publication-ready SVG/PNG for docs, with live preview as specs change.

SAAS

12 weeks • 70% confidence

Value Proposition

Eliminates 4-6 hours of manual Visio/draw.io work per protocol format; auto-calculates bit offsets and alignment; generates consistent, RFC-compliant visuals; version-controls diagram specs alongside code; integrates with CI/CD to regenerate diagrams on spec changes.

Target Audience

Protocol engineers at networking companies, embedded systems teams, blockchain projects, IoT firms, and open-source maintainers who document binary formats (Kafka, gRPC, custom protocols).

Key Features

  • Drag-and-drop field builder or text DSL for defining packet structures (name, bit width, type, description)
  • Automatic bit/byte offset calculation with visual alignment guides
  • Multi-format export (SVG, PNG, PDF, embedded HTML)
  • And more, with full implementation detail...

Tech Stack

React or Vue for editor UI D3.js or SVG.js for diagram rendering YAML/JSON parser (js-yaml, json-schema) Node.js backend with Express

Original Problem

Manual creation of binary protocol documentation diagrams is time-consuming and error-prone

Software engineers and protocol developers spend hours manually creating visual diagrams of binary protocol formats using generic tools like Visio or Excel, when they need to document multiple complex binary formats. Current solutions lack automation to generate RFC-style protocol visualizations from structured specifications, forcing developers to manually redraw fields, offsets, and bit layouts repeatedly across different document formats.
