.com vs .ai vs .app: which domain should you choose?
A founder-friendly comparison of .com, .ai and .app domains for startup naming decisions.
The best domain extension depends on what you are building and how customers will discover you. There is no single correct answer, but each extension creates a slightly different first impression.
For NameLuv, the goal is to surface names that feel usable for real products, whether the extension is .com, .ai or .app.
.com
.com remains the most familiar extension. It works across almost every category and is still the safest choice when you want a brand to feel broad, stable and easy to remember.
A strong .com can be useful for SaaS, marketplaces, consumer products, agencies and ecommerce brands.
.ai
.ai can make sense when artificial intelligence is central to the product. It signals category quickly, which can help if your audience is already looking for AI tools.
The tradeoff is that .ai can feel too narrow if the product later becomes more than an AI feature.
.app
.app is useful for software products, mobile apps, developer tools and lightweight utilities. It feels modern and product-focused.
It can be especially helpful when the matching .com is unavailable but the name itself is clean and memorable.
How to choose
Pick the extension that matches the promise you want the name to make. If you want maximum flexibility, .com is usually strongest. If you want category signal, .ai or .app can be a smart fit.
- Choose .com for broad brand flexibility
- Choose .ai when AI is central to the product
- Choose .app when the product is clearly software or app-led
