Is NanoID Taking Over UUID

  • Post published:October 22, 2021

Are you concerned about professional ID generators for software development? Are you confused about NanoID vs UUID?

Everyone knows UUID is one of the leading universal identifiers or ID generators. Over the past many years, people have started relying on alternatives that are more competitive and deliver more robust productivity.

Are you aware of the current leading competitor? NanoID is categorized as a leading competitor in comparison to UUID. If you are using Javascript for software development, generate either NanoID JS or UUID. They both are competitive and contain an NPM package to assist you.

It only demands you to install the NanoID JS NPM library through a simple command, i.e. npm I nanoid.


import {nanoid} from ‘nanoid’; = nanoid ()

Fact Check: NanoID is 60% faster and has over 11,769K weekly NPM downloads than UUID.

In this article, you will get to know the difference between NanoID vs UUID. We will elaborate on the differences between NanoID and UUID and why it is distinctive through its limitations.

Graphical Representation of NanoID vs UUID

The below-attached graph represents the difference of NanoID vs UUID through NPM trends; the upward trend of NanoID is progressing whereas the UUID graph line constantly declines.

NanoID vs UUID

The below-mentioned picture tells the relative difference between NanoID and UUID through different perspectives.

NanoID vs UUID

Fact Check: NanoID is seven years younger than UUID and has more GitHub stars.

Introduction to NanoID

NanoID JS is secure, tiny, URL-friendly, and contains a unique string ID generator.

1- NanoID is smaller in size in comparison to UUID

NanoID is quite easier and reliable to transform information and storage space as its size is compact.

2- NanoID rely on cryptographically strong API

A cryptographically strong API is a lot safer in comparison to Math.Random() that is usually insecure. Certain API modules are unpredictable hardware-generated random identifiers.

3- NanoID utilize a “uniform formula” throughout the application

NanoID is competitive due to its own “uniform formula” for the ID generator instead of relying on an arbitrary % alphabet that is commonly known as a mistake while coding an ID generator.

4- NanoID utilizes a larger alphabet

It results in short but shows unique identifiers.

5- NanoID permits designers to utilize personal alphabets

It is another function of NanoID that can alter the literals and dimensions of ID that is mentioned below:

Personalized letter as “1234567890ABCDEF” and dimension of the id as 10,

import {alphabet } from 'nanoid';
const nanoid = alphabet ('1234567890ABCDEF', 10); = nanoid();

6- NanoID is independent

NanoID is unique in comparison to UUID because it does not rely on third-party dependencies. It is a lot steadier and is helpful to enhance the package scope to make things less vulnerable directed to the issues generated through dependencies.

7- NanoID caters to various program languages

It includes several languages like C#, Dart and Flutter, C++, Go, JAVA, Python, PHP, Rust, Ruby, Swift, etc.

What are the distinctive features of NanoID to compete with UUID?

NanoID is distinctive in comparison to NanoID vs UUID due to the following points:

1. More Protective

Considering the random ID generators, they rely on unsafe Math.random(). NanoID is programmed to use a crypto module and web crypto API that are relatively more secure.

NanoID is distinctive because of the usage of its uniform algorithm during ID generation instead of using a random % alphabet.

2. More compatible

NanoID is distinctive because it supports PouchDB, Rollup, CouchDB WebWorkers, and libraries like react-native and React.

Try to attain a new ID through a specific command known as npx nanoid. The remaining prerequisite is to have NodeID JS installed.

Fast Productivity and Compact Design

NanoID is relatively 60% – 65% faster than the UUID, and NanoID contains 21 characters instead of 36 characters in UUID’s alphabets.


NanoID is relative and unique because it supports different languages that are as follows:

C#ClojureScript Nim
C++GoDart and Flutter
Python with dictionariesRubyPerl

According to the expert opinions, there are no significant disadvantages and limitations of utilizing NanoID. Non-human-readability is primarily the main disadvantage for developers because it makes debugging harder. Otherwise, there aren’t many limitations.

For the future, NanoID is the rising ID generator for JavaScript and has become every developer’s choice. They prefer it to UUID.

The below-mentioned benchmarks display the performance of NanoID in comparison to other ID generators:


Fact Check: NanoID is programmed systematically, generating over 2.2 million new IDs in one second with a single default alphabet. It involves over 1.8 million unique IDs through its custom alphabet design.

It is recommended that everyone start relying on NanoID for their upcoming projects considering its small size, security, URL friendliness, and speed.

In Essence

NanoID JS is a JavaScript library that is used for generating random IDs. Similar to UUID, you can somehow create duplicate IDs. However, this doesn’t happen all the time.
