analysis .build - gTLD (Generic Top-Level Domain)

[Eric Lyon]

Today, I'll be analyzing the .build gTLD to see if I can uncover any helpful data that could be stacked with someone elses research into the .build extension.

The registry operator for the .build generic Top-Level Domain (gTLD) is Plan Bee, LLC, which operates under the name "U-Label build," with its registry services managed by companies like GMO Registry and CentralNic Registry. Plan Bee, LLC was granted the registry agreement by ICANN in 2013 to serve the global construction and building industries online

Anyone can register a .build domain name for the construction industry (contractors, builders, architects, etc.), as there are generally no eligibility restrictions or documentation required for end-users, making it open for general public registration through registrars like GoDaddy or Namecheap after its launch phases, says GoDaddy and ChemiCloud, Namecheap. It's designed for businesses and individuals in construction and development to showcase projects and expertise

Note: At the time of this analysis there was a 3-character minimum to register a .build domain. There were several 3-character domains available, but with a $1k+ premium registration cost.

With the above in mind, let's dive right in...

.build domain registration costs​

According to Tldes.com the registration cost for a .build domain ranges from $25.20 to $34.99+.

.build domains registered today​

According to DNS.Coffee there are 8,025 .build domains registered today.

Public .build domain sales reports​

It's hard to find any .build domain sales online, indicating that most are private sales.

Note: NameBio.com shows 3 .build domain sales reports ranging from $130 to $2,079.

5-year .build domain growth summary​

Based on data from DNS.Coffee, the .build gTLD has experienced a total growth of 92.5% over the last five years, rising from 4,169 registrations in early 2021 to 8,025 by late 2025. The extension maintained steady, incremental growth for several years before seeing a significant surge in adoption during 2024 and 2025.

Five-Year Registration Growth (2021–2025)​

Date	Total Registrations	Year-over-Year Growth
Jan 2021	4,169	—
Jan 2022	4,534	+8.7%
Jan 2023	5,056	+11.5%
Jan 2024	5,526	+9.3%
Dec 2025	8,025	+45.2%

• Stable Early Growth (2021–2023): For the first three years of this period, the extension saw modest but consistent growth, averaging roughly 450 new net registrations per year. This reflected its status as a specialized niche for the construction and technology sectors.
• The 2025 Surge: The most dramatic increase occurred between January 2024 and December 2025, where registrations jumped by nearly 2,500 domains in less than two years. This aligns with a broader market trend where new gTLDs (ngTLDs) saw a 21.0% year-over-year increase in 2025.
• Current Standing: Despite the recent growth, the .build secondary market remains small. According to NameBio.com, there are only three publicly reported sales, the highest being move.build for $2,079.

Note: With a current total of over 8,000 domains, .build continues to establish itself as a focused alternative to mainstream extensions for developers and builders.

8 niches for .build domains​

1. General Construction: General contractors and construction firms of all sizes use .build to establish a clear, industry-specific online presence.
2. Architectural & Design Firms: Professionals and firms use this TLD to showcase their portfolios, services, and projects.
3. Engineering: Engineering companies and individual engineers utilize the domain to highlight expertise in building and design.
4. Real Estate Development: Developers use .build for specific new construction projects, providing updates and information to potential investors and buyers.
5. Building Product Manufacturers & Suppliers: Companies that manufacture materials, tools, or related products can use the extension for brand recognition and marketing to their target audience within the trade.
6. Software Development & Tech Platforms: Businesses building software or technology tools (e.g., project management solutions for the construction industry) find the term "build" highly relevant to their services.
7. DIY & Home Improvement: Individuals or groups running blogs, forums, or e-commerce sites focused on do-it-yourself projects and home renovation can use the domain to signal their expertise.
8. Specialized Contractors: Individual tradespeople such as electricians, plumbers, and carpenters can use .build domains to market their specific services and connect with clients.

What a playful .build domain hack might look like​

In the context of domain names, a "domain hack" is the practice of using the word before the dot and the domain extension (the TLD) together to spell out a complete word, phrase, or call to action. With 8,054 .build domains currently registered (according to DNS.Coffee), users are increasingly leveraging the extension to create memorable, action-oriented "hacks."

The Verb-Based Hack (The Call to Action)
Because "build" is a strong action verb, placing a noun or a project type before the dot creates an immediate command or mission statement.

• Examples: community.build, wealth.build, legacy.build, dreams.build.
• Why it works: It transforms a URL from a static address into a brand promise.

The Project/Product Hack
For companies in the software or physical construction space, the word before the dot identifies what is being constructed.

• Examples: robot.build, app.build, home.build, better.build.
• Why it works: It clearly defines the site's niche. The sale of move.build for $2,079 (reported by NameBio.com) is an example of a high-value project-based hack.

The "Stage" Hack (The Environment)
In technology and software development, "build" refers to a specific version or environment of a project. The word before the dot can represent the status of the software.

• Examples: stable.build, latest.build, nightly.build, final.build.
• Why it works: It mimics the terminology used by developers in version control systems (like GitHub).

The Compound Word Hack
Some of the most creative hacks involve words that naturally end with the "build" sound or suffix, though these are rarer in English than with extensions like .ly or .io.

• Examples: re.build (Rebuild), body.build (Bodybuild), over.build (Overbuild).
• Why it works: It creates a single, cohesive word across the dot, making it easier to remember and type.

The Niche Brand Hack
Small businesses often use their brand name as the "hack" to create a short, punchy URL that avoids the need for longer phrases like "construction" or "development."

• Examples: panda.build (Sold for $130) or character.build (Sold for $300).
• Why it works: It keeps the domain short and industry-specific, which is often cheaper than buying the equivalent .com (e.g., characterbuild.com).

Note: While .build remains a specialized niche, its growth from 4,169 registrations in 2021 to over 8,000 today demonstrates that more brands are finding value in these creative naming conventions.

Why the language before and after the dot should match​

Using English words before the dot is essential for maintaining linguistic consistency and brand clarity, as the ".build" extension is a recognizable English verb and noun. When both parts of the domain share the same language, the URL functions as a cohesive "domain hack" or semantic phrase—such as move.build or community.build—which improves user recall and intuitive navigation. This alignment is particularly important for the 8,054 registered .build domains (per DNS.Coffee) because the extension's value lies in its specific meaning within construction and technology; mixing languages can create cognitive dissonance, making the site appear less professional or confusing to the target audience. Furthermore, as shown by the NameBio.com report of move.build selling for $2,079, the most commercially viable domains are those that leverage a logical English pairing to create a memorable, action-oriented call to action.

10 lead sources for .build domain outbound campaigns​

1. LinkedIn Sales Navigator: This is the most powerful tool for B2B domain lead generation. You can filter by industry (Construction, Civil Engineering, Architecture & Planning, Computer Software), job titles (Project Manager, Architect, Software Developer, Founder), and location to find decision-makers at target companies.
2. Industry-Specific Online Directories: Websites that list contractors and construction professionals are a goldmine for targeted leads. Key examples include:
   • The Blue Book (focused on commercial projects)
   • BuildZoom (integrates permit data)
   • ConstructConnect (commercial & industrial focus)
   • Houzz and Angi (strong for residential contractors and designers)
3. Public Construction Permits/Records: Tracking public records of building permits provides real-time buying signals, identifying who is actively starting a new project and may need a professional online presence or a project-specific domain name.
4. Google Maps/Local Search: For targeting local businesses (e.g., a specific "builder in [City Name]"), Google Maps is excellent. Searching for "general contractors near me" reveals businesses that may have an outdated website or no website at all, making them prime candidates for an upgrade.
5. B2B Data Providers/Sales Intelligence Platforms: Tools like Apollo.io, ZoomInfo, and Cognism provide extensive databases with firmographic and technographic filters to build highly accurate and verified lead lists at scale.
6. Crowdfunding Platforms (Kickstarter, Indiegogo): Many new tech projects and hardware startups launch here. Project creators with successful campaigns are actively building something and often transition to a dedicated, professional domain name as they scale.
7. Webinar & Event Attendee Lists: Industry-specific events, both virtual and in-person, gather people with demonstrated interest in a topic (e.g., project management software, new construction techniques). Attending these events or partnering with organizers can provide access to high-intent attendee lists.
8. GitHub & Developer Communities: For leads in the software/tech niche, developers on platforms like GitHub who are managing open-source projects or new application builds are ideal prospects for a [projectname].build domain hack.
9. Competitor Websites & WHOIS Lookups: Look up companies using "build" as a keyword in their existing domain name (e.g., buildmyhome.com) but on a different TLD. A WHOIS search can provide owner contact information, identifying prospects ready for a brand-aligned .build upgrade.
10. Referral Programs and Existing Customers: A highly effective, low-cost method. Happy clients or existing contacts in your network are often willing to provide warm introductions to peers or partners in the construction/tech industry, leading to higher conversion rates.

Legal considerations when selling a domain to an existing businesss​

Approaching a business to sell a domain name similar to their trademark involves significant legal risks, primarily centered on "bad faith" intent. Under U.S. and international law, the act of offering a domain for sale to a trademark owner can itself be used as evidence of illegal activity.

Cybersquatting & The ACPA (U.S. Law)
The Anticybersquatting Consumer Protection Act (ACPA) allows trademark owners to sue if a registrant has a "bad faith intent to profit" from a mark.

• Proof of Bad Faith: Courts consider whether the domain was registered primarily to sell it to the trademark owner for "valuable consideration" exceeding out-of-pocket costs.
• Penalties: Violating the ACPA can lead to a court-ordered transfer of the domain and statutory damages ranging from $1,000 to $100,000 per domain.

UDRP Arbitration (International)
Most domain disputes are resolved through the Uniform Domain Name Dispute Resolution Policy (UDRP), an expedited administrative process. To lose a domain via UDRP, a trademark owner must prove:

• The domain is identical or confusingly similar to their trademark.
• The registrant has no legitimate rights or interests in the name.
• The domain was registered and is being used in bad faith. An offer to sell the domain to the trademark owner is a classic indicator of bad faith use.

Trademark Infringement & Dilution
Even if "bad faith" isn't proven, you may face infringement claims under the Lanham Act:

• Likelihood of Confusion: If a consumer might think your site is "used, approved, or permitted" by the trademark owner, it is likely infringing.
• Dilution: Famous brands (e.g., Starbucks, Pfizer) have extra protection against any use that weakens the distinctiveness of their mark, regardless of whether there is direct competition.

Key Considerations Before Outreach

• Trademark Search: Check the USPTO database to see if the name is protected. Trademarks only cover specific "classes" of goods; if your domain is for a completely different industry, the risk may be lower.
• Legitimate Interest: If you have an active business using the name for a purpose unrelated to the trademark owner, you have a stronger defense.
• The "Porkbun" Rule: Passive holding (parking the domain without a site) can still be seen as bad faith if the name clearly targets a specific brand.

Potential .build domain investing strategy​

Based on the recent growth and market analysis, the most effective investment strategy for the .build gTLD is a long-term "Niche Authority" approach. With a current registration count of 8,054 (according to DNS.Coffee) and a sharp 45.2% growth spike in 2025, the extension is transitioning from a dormant novelty into a specialized industry standard.

Target High-Value English Domain Hacks
The most successful strategy for this extension is creating semantic "hacks" that form logical English phrases. Public sales data from NameBio.com, though limited, shows that the highest-value transaction was move.build ($2,079).

• Focus: Register "Verb + .build" or "Noun + .build" combinations that serve as calls to action (e.g., community.build, legacy.build).
• Criteria: Stick to short, easy-to-pronounce words that pass the "radio test"—memorable names that a business can use for an entire brand identity.

Industry-Specific Acquisition (The "Rolling Money" Rule)
Investors should focus on sectors with high commercial intent where "building" is a core activity.

• Top Niches: Focus on Construction Tech (ConTech), Software Development, and Architecture.
• Avoid: Generic or hobbyist terms (e.g., model.build) as these rarely command high resale prices from individual enthusiasts.

Patient Long-Term Holding
Unlike the high-volume flip market for extensions like .com, .build is an illiquid asset that requires patience.

• The 3+ Year Hold: Market data for 2025 shows that 48% of successful domain investors hold their niche assets for 3 or more years.
• Renewal vs. ROI: With registration costs around $25.20 at Cloudflare, a domain must sell for at least $250–$500 to justify a decade-long holding period.

Active Outbound Strategy
Because .build is a niche extension, passive listings on marketplaces are often insufficient.

• Strategy: Identify startups or agencies currently using longer, clunkier .com names (e.g., citybuildersoftware.com) and pitch them a concise .build upgrade (e.g., city.build).
• Risk Management: Always conduct a trademark search before reaching out to existing businesses to avoid "bad faith" legal disputes under the ACPA.

Portfolio Diversification
Do not over-allocate capital to a single niche TLD. A balanced 2025 strategy often follows a 40/40/20 split: 40% established .coms, 40% high-growth niche TLDs (like .build or .ai), and 20% emerging or experimental plays.
