UUID Generator FREE
Generate UUIDs in bulk: version 4 for pure randomness, version 7 when the identifier should sort by the time it was made. Both follow RFC 9562.
Tokens and IDs
These are identifiers and codes, not passwords. A password you have to copy out of a web page is one your password manager should have made and stored for you.
Result
Every draw is made in this tab by your browser's cryptographic random number generator. Your list, your numbers and the result are never sent anywhere and nothing is stored.
v4, v7, and which to use
A version 4 UUID is 122 random bits with the version and variant fields set as RFC 9562 requires. Two of them are unrelated and unordered, which is what you want for something that must not leak when or in what order it was created.
A version 7 UUID starts with the 48-bit Unix millisecond it was created in and fills the rest with random bits. They sort by creation time as plain text, which is far kinder to a database index, and it also means a v7 identifier tells anyone who reads it when it was made.
Both are generated here from crypto.getRandomValues, up to ten thousand at a time, and the same panel makes random bytes as hex and tokens over several alphabets. Nothing is sent anywhere: an identifier a server saw on its way to you is one somebody else has a copy of.
Chrome vs Firefox vs Edge vs Safari: what we learned from shipping 9 browser extensions
Nine extensions, four browsers and far more than one `manifest.json` file. We show where shared code really ends, why Safari needs a separate process and which bugs are exposed only by Firefox and extension stores.
Claude Code vs OpenAI Codex vs Gemini CLI: the best AI coding agent in 2026
Claude Code, OpenAI Codex, and Gemini CLI can read repositories, edit files, and run tests, but they were designed for different styles of work. We compare quality, benchmarks, security, parallel execution, extensions, pricing, and privacy.
How Custom Software Helps Teams Automate Repetitive Work
Not every task should be automated, and not every automation needs a full product. The useful skill is deciding which tasks are worth it, and then building the smallest tool that actually removes them.
