UUID Generator
Generate any number of UUIDs in v4 (random) or v7 (time-ordered, sortable) form, and copy them out as standard hyphenated form, hyphen-less, or uppercase. v4 uses crypto.randomUUID; v7 embeds a millisecond timestamp so IDs sort chronologically — perfect for database primary keys. Free, online, runs locally.
