Developer tool name generator
Short, typeable names for CLIs, SDKs, open-source libraries and APIs, checked live for .dev, .io and .com availability.
What makes a good developer tool name
Developers type your name dozens of times a day: in a terminal, in a package.json, in a config file. That changes the rules. The name must be lowercase-friendly, free of digits and look-alike letters, short enough for a command, and unclaimed on npm, PyPI, crates.io and GitHub as well as on the domain registries. The generator here is set to short names and the .dev, .io and .com extensions that developer products actually use.
Say what the tool does in one line and mention the ecosystem (Node, Python, Rust, Postgres). The AI will blend domain words with the command-line feel developers expect, and the Pulse score will reject anything with a consonant cluster that is painful to type.
Tips that save a rename
- Check the package registries (npm, PyPI, crates.io, Go modules) before the domains; a free .dev is worthless if the npm name is taken.
- Avoid names that shadow common Unix commands or existing popular tools (grep-like names, "make", "build").
- Five to seven lowercase letters, no hyphens: it has to work as a command and a GitHub org.
- Reserve the GitHub organisation the same day you buy the domain.
Is .dev a good domain for a developer tool?
Yes. It is HTTPS-only, clearly technical and much less crowded than .io. Many popular tools use .dev as their primary site.
Should the name match the command name?
Ideally yes. One name across the command, the package and the domain reduces friction and makes documentation searchable.
How do I check if the name is free on npm or PyPI?
Search the registry websites or run the install command for the name. We only check domains; registries have their own namespaces.
How it works
From a one-line idea to a registered domain in under a minute.
Describe your project
Tell us what you're building and who it's for. Pick a naming style, force a keyword in, or cap the length.
Get 24 scored names
Our AI mixes invented words, blends and clever twists, and every name gets a Pulse score for how easy it is to say, spell and remember.
Shortlist & register
We check DNS and official registry (RDAP) data live. Heart your favourites, share the shortlist, and grab an available domain with one click.
Built to actually pick a name
Generating ideas is easy. Deciding is hard. These help you decide.
Pulse score
A 1–10 brandability estimate from length, syllables and pronounceability, so you compare names on more than gut feel.
Shortlist & share
Heart names as you go. Share one link with a co-founder; it reopens the list with fresh availability.
Variations
Like the sound of one name? Spin 24 variations around it, in the same mood and rhythm.

Frequently asked questions
Everything you need to know about our domain name generator.
Is NamePulsar free?
Yes. Generating names, scoring them and checking availability is free and needs no account. When you register a domain, you do it directly with the registrar.
How accurate is the availability check?
We query DNS and the official RDAP registry data in real time. “Available” means the registry has no record of the domain. “Likely available” means the domain has no DNS records but that registry doesn't offer RDAP to confirm. Premium or reserved names can still cost more at the registrar, so always confirm at checkout.
What is the Pulse score?
A 1–10 brandability estimate based on length, pronounceability, syllable count and spelling pitfalls (digits, awkward consonant clusters, double letters). It helps you compare names; it says nothing about trademarks, so run a trademark search before you commit.
Which domain extensions are supported?
.com, .io, .ai, .co, .app, .dev, .net, .org, .xyz, .me, .eu, .de and .ro. Choose the ones you care about before you generate, or hit “all extensions” on any card.
Do you store my project description or shortlist?
No. Your description is sent to the AI model to generate names and isn't saved by NamePulsar. Your shortlist lives only in your browser; share links simply carry the names in the URL.
What makes a good brandable domain name?
Short (ideally under 10 characters), easy to spell after hearing it once, easy to pronounce, distinctive enough to trademark, and available as a .com or a strong alternative like .io or .ai.
