DevSandbox Keeps Developer Utilities in the Browser
A client-side toolbox for formatting JSON, testing regexes, decoding tokens, converting timestamps, and handling other everyday developer chores.
- For
- Developers debugging snippets, tokens, schedules, and configuration files
- Worth noticing
- A smart paste entry point detects seven input formats and routes each to a specialized tool.
Field notes
The toolbox divides its utilities into Data & JSON, Encoding & Crypto, Time & Scheduling, Code & Text, and Security & Tokens. Its smart paste workflow is designed to identify formats before sending a user to a specialized page, while the site says browser-native APIs and a restrictive Content-Security-Policy keep processing local. The extract also shows a search interface and a recently used area, but does not establish how every individual utility behaves.
