# My Dev Tools > A developer workspace with 147 tools for formatting, validation, conversion, inspection and debugging. Version 2.1.0. Local processing by default; network boundaries are shown per tool. No account is required to open the tools. Saved projects and preferences stay in the current browser or desktop profile. Vaults use passphrase-protected encryption. Tool inputs, credentials and saved records are not public documentation and are not exposed by these discovery files. The web app needs JavaScript for interactive execution. Previously cached local tools can work offline; network tools and uncached model weights need connectivity. The desktop edition bundles local runtime assets. Native connectors are not public execution APIs. Interface language choices are English, Hindi, Spanish, French, German, Japanese, Chinese and Arabic; detailed copy may fall back to English. ## Documentation - [Tool catalog](https://mydevtools.com/tool-catalog.md): Every canonical tool URL, description, category and processing boundary. - [Current release](https://mydevtools.com/release-notes.md): Version 2.1.0 capabilities and scope. ## Optional - [Machine-readable catalog](https://mydevtools.com/agents.json): Custom read-only catalog; not an A2A card, MCP server or execution API. - [Combined documentation](https://mydevtools.com/llms-full.txt): Catalog and current release in one response. - [Interactive workspace](https://mydevtools.com/): Open tools and search the catalog. - [Sitemap](https://mydevtools.com/sitemap.xml): Indexable HTML pages.
