What each tool is for

- Meta tag generator — write a title and description that fit in Google’s results and preview how a link will look when shared.

- SQL query formatter — turn one-line queries from logs into indented SQL that is easy to review.
Safe for private code
Developers often paste API keys, customer records or internal queries into online formatters without thinking about where the text goes. These tools process everything in your browser tab. Nothing is uploaded, logged or cached on a server, which makes them suitable for data covered by an NDA or a privacy policy. You can confirm this yourself: open your browser’s developer tools, watch the Network tab, and format a document. No request is made.
Built for repeat use
Each tool supports keyboard input, copy-to-clipboard and file download, and keeps working offline once the page has loaded.
Frequently asked questions
