Developer Tools

Small utilities for everyday programming: format and validate JSON, YAML, XML and SQL, decode Base64 and JWTs, test regular expressions, compare two files, generate UUIDs and hashes, read cron expressions and convert timestamps.

Paste something in, get the answer, move on. Most of these tools do their work inside your browser, so the data you paste is not uploaded. The few that need the network, such as the Open Graph preview and the webhook inspector, say so on the page.

Questions

Is the data I paste sent to a server?

Formatters, encoders, generators and the diff tool run in your browser. Tools that have to fetch a URL for you make one request to that URL and nothing else.

Do the tools work offline?

Once a page has loaded, the browser-side tools keep working without a connection.

Is there a size limit?

Browser-side tools are limited only by your device memory. Documents of a few megabytes are fine.
