Playground
Write rules and data, and the result updates as you type.
Data
Rules and data are JSON5: keys may be unquoted and strings single-quoted. The link in the address bar always holds what you typed, so you can share it.
Besides the standard rules, the playground has the rules of livr-extra-rules that are not in LIVR 2.5: ipv4, is, md5 and list_items_unique. Other implementations may not have these rules. The rules of livr-extra-rules with the names of LIVR 2.5 rules (boolean, uuid, iso_date with options, ...) are not registered, so these names are the standard rules, see the migration table.
