About DevScratchpad
DevScratchpad is an active, source-available developer productivity suite providing over 30 client-side utilities and an AI agent prompt steering studio. Every feature runs 100% inside your browser memory with zero server data transmission.
Why We Built DevScratchpad
Modern developers frequently work with confidential credentials: production JWT tokens, proprietary JSON payloads, private SSH keys, and sensitive API cURL requests. Many legacy online formatters transmit this payload data to remote servers or log it into cloud analytics databases.
DevScratchpad was engineered as a zero-trust client-side alternative. By utilizing browser Web Workers, WebAssembly, and native Web Cryptography APIs, all transformations and cryptographic operations occur exclusively in local memory on your device.
Core Architecture & Features
No remote servers receive your clipboard or input data. The code is auditable in our public GitHub repository.
Direct clipboard auto-detection recognizes JWTs, cURL commands, SVG markup, JSON, SQL, and timestamps to launch tools instantly.
Specialized generator for Claude Code agent skills (SKILL.md), Cursor Project Rules (.cursor/rules/*.mdc), and multi-agent systems (AGENTS.md).
Installable on desktop and mobile. Every tool runs in your browser, and a tool that is already open keeps working if your connection drops.
Auditable & Source-Available
