.com vs .io vs .dev vs .gg: choosing a TLD

The TLD — the bit after the dot — is a branding decision as much as a technical one. .com, .io, .dev and .gg each carry a different signal and suit different projects. Here's an honest look at the popular options and how to choose.

.com — the default

.com is still the ending people assume, type by reflex, and trust instinctively. If your .com is available and affordable, it's the safe choice for almost anything, especially a business aimed at a general audience.

• Signals: established, trustworthy, mainstream.
• Downside: the most competitive namespace — good short .coms were registered long ago, so you may need a longer or more creative name.
• Pricing: generally low and stable.

.io — tech and startups

.io became the darling of startups, developer tools and SaaS. It reads as modern and technical, and "io" nicely echoes input/output.

• Signals: tech-forward, startup, developer-oriented.
• Downside: typically costs noticeably more than .com, both to register and renew. It's technically a country-code TLD, though it's used globally.
• Good for: apps, dev tools, tech startups.

.dev — for developers, HTTPS-first

.dev is run by Google and aimed squarely at developers and projects. It has one notable technical feature: the entire TLD is on the HSTS preload list, meaning browsers *require* HTTPS for every .dev domain.

• Signals: developer projects, tools, documentation, portfolios.
• Quirk: you *must* serve over HTTPS — there's no plain-HTTP option. In practice that's a good habit anyway, and free Let's Encrypt certificates make it a non-issue.
• Good for: developer portfolios, open-source projects, internal tools.

.gg — gaming and communities

.gg is beloved in gaming culture ("gg" = good game) and is common for communities, servers and esports.

• Signals: gaming, community, esports.
• Downside: usually one of the pricier TLDs. Also technically a country code (Guernsey), used globally for its gaming association.
• Good for: game servers, Discord communities, esports teams, gaming brands.

Other options worth knowing

• .co — a popular .com alternative; short and brandable, widely accepted.
• .app — like .dev, HTTPS-enforced; great for applications.
• .net / .org — older alternatives; .org still signals non-profit and community.
• Country codes (.de, .co.uk, .in, etc.) — strong for businesses targeting a specific country.

How to actually choose

Run your decision through a few questions:

• Who's your audience? A general business leans .com; a dev tool fits .io or .dev; a gaming community suits .gg.
• Is the .com available? If yes and it's affordable, it's rarely wrong.
• What's the renewal price? Premium TLDs like .io and .gg cost more every year, not just once — budget for the long term.
• Any technical constraints? .dev and .app require HTTPS; plan for that (it's easy).

The honest bottom line

There's no single best TLD — there's the right one for *your* project and audience. .com is the safe default, the newer TLDs let a taken-.com name still work beautifully, and a well-chosen ending can even reinforce your brand. Whatever you pick, Nxeon can register it through name.com and point it at your server from the same dashboard, so the ending you choose is the only decision you need to labour over.
