Developer utilities, kept practical
Tool Lockers brings common formatting, conversion, inspection, and generation tasks into one focused workspace.
What it does
The toolkit includes utilities for JSON, regular expressions, Base64, CSV, URLs, timestamps, text comparisons, hashes, UUIDs, SQL, cron expressions, and more. Each tool is designed for a specific everyday task, with its own page and direct access from the tool directory.
How tools work
Most transformations run in your browser. The API Tester is different: it sends the request you configure to the destination you enter, subject to browser and destination security policies. Review the Privacy Policy before sending sensitive data.
Our approach
The goal is to make useful developer workflows easy to reach, clear to operate, and honest about their limitations. Outputs should be reviewed before being used in production systems.
