About

Devscribe is a unified desktop workspace built to boost developer productivity. Instead of juggling multiple apps for documentation, architecture design, database modeling, and code execution, Devscribe combines everything into one fast and streamlined experience. ### With Devscribe, you can: - Write technical documentation and notes - Design **HLDs**, **LLDs**, and **system architecture diagrams** - Create **API documentation** and **test APIs** directly inside the workspace - Build **ERDs** and visualize database relationships clearly - **View and explore databases** to understand structure and connectivity - Run code snippets in **Java, JavaScript, TypeScript, SQL, and Shell** - Work fully **offline**, with complete data privacy

Key Features

Unified Developer Workspace

Consolidate documentation, diagrams, code snippets, database exploration and API testing into a single offline desktop app to avoid context switching.

Diagramly Visual Designer

Integrated diagram editor for ERDs, UML class diagrams, HLD/LLD and architecture diagrams with export to PNG/SVG and support for common cardinality/relationships.

In-Document Multi-language Code Execution

Run JavaScript, TypeScript, Java, Shell and SQL code snippets directly inside documents with console output — no external terminal or setup required.

API Documentation & Testing

Document APIs and execute real requests from within the workspace, view formatted JSON/tabular responses and manage reusable environment variables (no external Postman required).

Local-first Privacy & Offline Mode

All data stored locally with zero server connections — works entirely offline for maximum privacy and secure environments.

How to Use DevScribe

1) Download and install Devscribe for macOS or Linux and open the app. 2) Create a new document or open an existing project — write docs with normal text and embed code blocks for snippets. 3) Use the /diagram command to insert Diagramly diagrams (ERD, UML, HLD/LLD), draw and export diagrams as PNG/SVG. 4) Add runnable code blocks (JS/TS/Java/Shell/SQL) and press run to execute; use the API tool inside the document to define and test endpoints with environment variables. Everything runs locally and works offline.

Use Cases

•Design and document system architectures: create HLD/LLD diagrams, annotate architecture choices and include runnable code examples and configuration snippets in one document for handoffs between architects and engineers.

•Database modeling and exploration: build ERDs, visualize table relationships, run SQL queries against local demo or SQLite databases and document schema rationale alongside diagrams.

•API documentation and testing: write API docs, define endpoints and environments, execute live requests and capture formatted responses — all inside the same offline workspace for secure API validation and sharing.
