UUID/GUID, CUID & NanoID: What's The Difference?

• nanoid

  83 23,187 8.3 JavaScript

  A tiny (124 bytes), secure, URL-friendly, unique string ID generator for JavaScript

NanoID's website has a cool visualiser tool in it, where we can calculate the chances of a collision. With an ID length of 15 characters (pretty short and sweet), and a generation of 1,000 IDs every second, it'll take a mind boggling 569 thousand years for it to have a 1% probability of a single collision. Now if we switch that to 1000 IDs being generated every single second, it'd still take around 158 for it to have a 1% probability of at least a single collision. That's longer than me or you will probably live.

• cuid

  8 3,338 2.8 JavaScript

  Collision-resistant ids optimized for horizontal scaling and performance.

  

CUID aims to solve the exact problem we discussed above with UUIDs. Quoted from CUID's GitHub:

So recently, I was on a live steam with @aydrian on Twitch where I demonstrated how to migrate a live serverless application (Next.js and Vercel) from PostgreSQL database onto CockroachDB serverless with zero application downtime. If you're interested in that, please do check out the video.
