About StrateCode DevTools

Who is behind the site

StrateCode DevTools (stratecode.tools) is operated by Strategic Code Solutions SL, which trades as StrateCode. The company was registered in Madrid in 2024 and works on IT consultancy, custom software and web development, and cybersecurity. You can find more about the company at stratecode.com.

What the site is for

The site collects small utilities for everyday development work: formatting and validating JSON, YAML, XML and SQL; encoding and decoding Base64, URLs and JWTs; generating UUIDs, hashes and passwords; checking cron expressions, regular expressions, HTTP headers and configuration files. Each tool page explains what the tool does, how to use it and where its limits are, so you can decide whether the result is good enough for your case.

The tools are free to use, need no account and have no usage limits. The site is funded by advertising, which is only personalised if you allow it in the consent banner. See the advertising disclosure for details.

How the tools handle your data

The site is a set of static pages. When you paste text into a tool, the conversion, validation or analysis runs in JavaScript inside your browser; the input is not sent to our servers. You can check this yourself: open your browser's developer tools, go to the Network tab and use any tool. No request carries your input.

Two things do involve third parties: the hosting provider that serves the pages (and therefore sees standard request data such as your IP address), and, only if you consent, Google Analytics and Google advertising services. The privacy policy and cookie policy describe exactly what is collected and how to change your choice.

How the tools are built and checked

• The logic of each tool lives in its own TypeScript module, separate from the page, and is covered by automated tests: example-based unit tests plus property-based tests that run each function against many randomly generated inputs (for instance, that encoding and then decoding returns the original text).
• Where a mature open-source library exists, we use it instead of reinventing it, for example js-yaml for YAML, Ajv for JSON Schema, sql-formatter for SQL, jose for JWT signatures and cron-parser for cron expressions.
• The explanations and examples on each tool page are written for developers and checked against the tool's actual output. If something is wrong or unclear, please tell us.

The tools are meant for development, debugging and testing. For anything critical (production configuration, security decisions, financial data) verify the result with a second method.
