Description of service

Devstackkit provides 53 free, browser-based developer tools (formatters, parsers, converters, security/hashing/encryption utilities, generators, and related utilities). No account or sign-up is required, and there are no usage limits. All processing happens locally in your browser — see our Privacy Policy for details on what data, if any, is stored and where.

Acceptable use

You agree not to use this site for any unlawful purpose, to attempt to disrupt, overload, or gain unauthorized access to the site or its infrastructure, or to use automated means to scrape or abuse the service in a way that degrades it for other users.

No warranty ("as is")

This site and its tools are provided "as is" and "as available," without warranties of any kind, express or implied, including — without limitation — warranties of accuracy, reliability, fitness for a particular purpose, or uninterrupted availability.
