No KYC, paid in crypto. - URL: https://dotalmanac.com/guides/ - Last updated: 2026-10-29 - Publisher: DotAlmanac (https://dotalmanac.com) Every guide of the almanac in one place, grouped by question. Choose an extension, compare two of them, check what renewals cost, or set up the domain. **Quick answer — What do DotAlmanac's domain extension guides cover?** **DotAlmanac** is a domain extension guide and registrar: compare every extension, then register it with no KYC and pay in crypto. As of 29 October 2026, its domain extension guides cover four needs. They help you choose an extension, compare two of them, read renewal data on 225 extensions and set up DNS. ## Choose: which guide helps me pick an extension? Start with the method, then read the page for your type of project. Each page gives a clear pick, the first-year and renewal price of the options, and the traps to avoid. - **[How to choose a domain extension](https://dotalmanac.com/how-to-choose-a-domain-extension/ "How do I choose the right domain extension?")** — The method in steps, with a decision table: if your project is this, pick that. - **[Best domain extensions (2026)](https://dotalmanac.com/best-domain-extensions/ "What are the best domain extensions in 2026?")** — Ten extensions ranked on price, renewal, registry rules and how people read them. - **[Best extension for a startup](https://dotalmanac.com/best-domain-extension-for-startups/ "What is the best domain extension for a startup?")** — Which extension a new product should use, with first-year and renewal prices side by side. - **[Best extension for an AI company](https://dotalmanac.com/best-domain-extension-for-ai-companies/ "What is the best domain extension for an AI company?")** — When .ai is worth its 2-year minimum term, and what the alternatives cost. - **[Best extension for developers](https://dotalmanac.com/best-domain-extension-for-developers/ "What is the best domain extension for a developer?")** — Extensions for tools, documentation and side projects, compared on price and HTTPS rules. - **[Best extension for an online store](https://dotalmanac.com/best-domain-extension-for-online-stores/ "What is the best domain extension for an online store?")** — Extensions for shops and brands that sell online, with the renewal cost over several years. - **[Best extension for a personal website](https://dotalmanac.com/best-domain-extension-for-personal-websites/ "What is the best domain extension for a personal website?")** — Extensions for a portfolio, a CV or a blog, with a clear pick for each case. - **[Best extension for gaming](https://dotalmanac.com/best-domain-extension-for-gaming/ "What is the best domain extension for a gaming site?")** — Extensions for teams, game servers and streamers, including the rules of .gg. - **[What is a TLD?](https://dotalmanac.com/what-is-a-tld/ "What is a TLD (top-level domain)?")** — gTLD, ccTLD, new gTLD, sTLD, IDN, registry and registrar, defined in plain words. - **[Country domains without living there](https://dotalmanac.com/can-you-register-a-country-domain-without-living-there/ "Can you register a country domain without living there?")** — Which country codes are open to anyone, and which require residence or a local presence. ## Compare: which page settles X vs Y?

It ends with a verdict for each type of project. - **[.io vs .com](https://dotalmanac.com/io-vs-com/ "Is .io better than .com for a startup?")** — The startup question: a tech signal against the default extension, with the .io renewal of $52.49/year. - **[.ai vs .io](https://dotalmanac.com/ai-vs-io/ "Should an AI startup use .ai or .io?")** — Two tech country codes: the 2-year minimum of .ai against the Chagos question of .io. - **[.com vs .net vs .org](https://dotalmanac.com/com-vs-net-vs-org/ "Should I choose .com, .net or .org for my website?")** — The three historic extensions: who each one suits today, and what each costs to keep. - **[.co vs .com](https://dotalmanac.com/co-vs-com/ "Is a .co domain as good as a .com?")** — Colombia's country code against .com: price, perception and the 5-year maximum term. - **[.app vs .dev](https://dotalmanac.com/app-vs-dev/ "Should I use .app or .dev for my project?")** — Two Google Registry extensions with HTTPS required: which one fits a product, which one a developer. - **[.xyz vs .com](https://dotalmanac.com/xyz-vs-com/ "Is .xyz a good domain, or should you buy a .com?")** — Is .xyz a good domain?

Each guide carries the date of its last check. Our own prices come from the live price grid, so they change on every page at once. Competitor prices carry the date of the price list they come from, and we check them again each month. Registry rules come from the registries, IANA and the sources named on each page. If you find an error, write to support@dotalmanac.com; the [about page](https://dotalmanac.com/about/ "Who runs DotAlmanac, and how is the almanac made?") describes the method. ## Guides: questions ### Where should I start if I have no idea which extension to pick? Start with [how to choose a domain extension](https://dotalmanac.com/how-to-choose-a-domain-extension/ "How do I choose the right domain extension?"). It asks who will type the name, what the project is and how long you will keep it. Then it points you to the right comparison. ### Are the prices in the guides the same as on the pricing page? Yes. Our own prices on every guide come from the same price grid as the [pricing page](https://dotalmanac.com/pricing/ "How much does a domain name cost per year?"), dated 29 October 2026. A .com costs $11.99/year everywhere on the site. ### Can I reuse your data in an article? Yes. The two reports, the [renewal price index](https://dotalmanac.com/data/domain-renewal-price-index-2026/ "How much does it cost to renew a domain in 2026?") and the [extension rules table](https://dotalmanac.com/data/domain-extension-rules-2026/ "What are the registration rules of each domain extension?"), are published under the CC BY 4.0 licence. Cite DotAlmanac with a link to the page. ### Do the guides recommend only extensions you sell? No. Some guides mention extensions we do not sell, such as .sh or .eu, and say so. When another registrar sells an extension for less, the guide names it with the date of the check. ## Sources 1.
