1and1 Usage Statistics

How has 1and1 adoption changed over time? 1and1 grew from 3,169 active domains in August 2012 to a peak of 387,333 active domains by April 2025, based on our monthly crawl data at TechnologyChecker.io. That's a 122x increase over roughly 13 years. Adoption accelerated fastest during 2013-2018, jumping from under 10K to over 200K domains as the company expanded across European markets. Since mid-2025, however. We've observed a decline. Active domains dropped to around 335K by July 2025. This downward trend coincides with broader hosting market consolidation around cloud-native providers like Cloudflare.

Which Countries Use 1and1 the Most?

Which countries use 1and1 the most? Germany dominates with 37,974 enriched companies, roughly 39.3% of all 1and1 customers, reflecting the company's German origins (founded in Karlsruhe in 1988), based on our analysis of 62,130 enriched companies at TechnologyChecker.io. The United Kingdom follows at 14.5%, with the United States close behind at 14.4%. France (11,222 companies) and Spain (11,212) round out a heavily European top five. In total, European countries account for over 70% of the user base. This means 1and1's infrastructure, documentation, and support are improved primarily for European markets, something US-based buyers should factor in.

1and1 Market Share Among Web Hosting

What is 1and1's market share? 1and1 holds a 2.65% share of the web hosting market, ranking #11 in the category, based on our monthly crawl of 50M+ domains and 40K+ tracked technologies at TechnologyChecker.io. That puts it well behind the leader, Cloudflare Hosting at 33.43%, and also behind GoDaddy (4.51%) and Hostinger (4.56%). For a provider that's been in the market since 1988, a sub-3% share tells a story of missed opportunities in cloud migration. The hosting market has consolidated sharply, and 1and1's traditional infrastructure hasn't kept pace.

Top Competitors by Market Share

1and1 Customers by Company Size & Age

Is 1and1 only for small businesses? The data doesn't just lean small. It's overwhelmingly micro-business. A full 91.9% of 1and1 customers have 1-10 employees, based on our analysis of 62,130 enriched companies at TechnologyChecker.io. Another 5.5% fall in the 11-50 range. Only 0.04% of customers qualify as enterprise (10,001+ employees), though those 38 companies include household names like Honeywell, Roche, and Deutsche Telekom. For sales teams: if you're targeting mid-market or enterprise, 1and1's customer base won't be your primary hunting ground.

What Industries Use 1and1 the Most?

What industries use 1and1 the most? Business Consulting and Services leads at 6.49% with 4,936 companies, followed by Construction at 4.97% (3,781 companies), based on our analysis of 62,130 enriched companies at TechnologyChecker.io. But here's the telling detail: no single industry exceeds 7%. The distribution is remarkably flat across retail (3.49%), IT services (3.29%), real estate (3.22%), and advertising (2.9%). This makes 1and1 a genuinely horizontal platform. It doesn't specialize in any vertical, which means there are no industry-specific switching costs keeping customers locked in.

Real Estate2,448 (3.22%)

How do specific industries break down on 1and1? Construction companies using 1and1 account for nearly 5% of the customer base at 3,781 companies, per our enriched data at TechnologyChecker.io. Retail businesses on 1and1 represent 3.49% with strong European presence, consistent with the platform's geographic profile. IT Services firms using 1and1, including companies like Computacenter, demonstrate that technical buyers do use the platform, though often for specific subdomains rather than primary infrastructure. Medical Practices (2.38%) and Professional Training (1.93%) show 1and1's reach into service-oriented industries.

1and1 Alternatives & Competitors

Who are 1and1's biggest competitors? The web hosting market is heavily fragmented, and 1and1 sits in the middle of the pack. Cloudflare Hosting dominates at 33.43% market share, over 12x 1and1's 2.65%, with modern CDN-based infrastructure that appeals to performance-focused buyers, based on our market share data across 50M+ crawled domains at TechnologyChecker.io. In the SMB segment where 1and1 actually competes, GoDaddy (4.51%) and Hostinger (4.56%) are the closest rivals. Both are growing faster. Squarespace Hosted (4.93%) targets a different audience with website-builder-first hosting, but still ranks above 1and1.

1and1 Customer Reviews with Pros and Cons

What do users say about 1and1? Based on aggregated G2 reviews, 1and1 (IONOS) scores well for ease of use and affordable pricing, with users noting the simplicity of account management and email setup. The most common complaint? The dashboard can feel cluttered, making navigation tricky for new users. G2 review volume for 1and1 specifically is limited, likely because most recent reviews reference the IONOS brand instead.

Generated from real user reviews on G2

Pros

Cons
  • Many appreciate the reliable performance and 24/7 accessibility, although some note that the dashboard can be cluttered, making navigation challenging for new users.

Expert Analysis: 1and1 Growth Trends & Key Signals for Sales Teams in 2026

David Thomson
David ThomsonCTO, TechnologyChecker

As of our March 2026 crawl, TechnologyChecker.io tracks 387,287 domains hosted on 1and1 (now IONOS) and 62,130 enriched company profiles matched to LinkedIn data. This European hosting provider has been around since 1988, but our data shows it's gradually losing ground to cloud-native competitors, creating both challenges and opportunities for sales teams.

Growth Trajectory

1and1 holds just 2.65% of the web hosting market, ranking #11 behind cloud-native platforms like Cloudflare Hosting (33.43%) and established competitors like GoDaddy (4.51%). That's a weak position for a company with 37 years of history. After peaking at 387,333 active domains in April 2025, our monthly crawl shows a meaningful decline, dropping to roughly 335K by July 2025. The most striking data point sits in the churn numbers: we've detected 417,355 sites that previously used 1and1, which is actually more than the current active count. A near-1:1 ratio of former to current customers signals persistently high churn. Compare that to Shopify, which shows a much healthier 1.3M former vs. 2.4M active ratio.

Sales Signal: The 417K+ former customer list is a goldmine for competitors. These companies already made a hosting decision once and then switched. They're warmer leads than cold outreach. If you're prospecting 1and1 customers with a migration pitch, lead with performance and price. Our data shows those are the two levers that drive churn away from this platform.

"1and1 has more former customers than active ones, 417,355 vs. 387,287. That's one of the highest churn ratios in the entire web hosting category." - Mehmet Suleyman, CEO at TechnologyChecker.io

Customer Profile

The data is unambiguous. A full 91.9% of 1and1 customers have 1-10 employees, based on our analysis of 62,130 enriched companies. This isn't an SMB platform. It's a micro-business platform. Only 38 companies in our entire dataset qualify as enterprise (10,001+ employees), and most use 1and1 for specific subdomains rather than core infrastructure. Notable enterprise names include Honeywell, Telefonica, Roche, Bayer, and 3M, but they're outliers deploying 1and1 on secondary properties. Company age adds context: 42.04% were founded in the 2010s (during the platform's growth era), while only 21.88% are 2020s-founded, suggesting new startups aren't choosing 1and1.

Sales Signal: If you sell to micro-businesses in Germany, the UK, or France. This is a rich prospect pool of 62,130 LinkedIn-matched companies. If you're targeting enterprise or mid-market, look elsewhere, the 91.9% micro-business concentration means your win rate will be near-zero for deal sizes above $5K/year.

Industry and Geographic Concentration

Germany accounts for 39.3% of all customers, nearly triple the UK (14.5%) or US (14.4%). That concentration reflects 1and1's German origins and explains why it struggles to compete globally against US-based alternatives. France comes in at roughly 7%, making the DACH + France region over half the customer base. No single industry exceeds 7%: Business Consulting leads at 6.49%, Construction at 4.97%, Retail at 3.49%. The flat distribution means 1and1 has no vertical specialization. And therefore no industry-specific switching costs. Customers can leave without losing specialized features, which partly explains the high churn we observe.

Sales Signal: Horizontal positioning cuts both ways. Competitors selling vertical-specific solutions (healthcare hosting, ecommerce platforms) can peel off customers with targeted messaging that 1and1 can't match. The Germany-heavy distribution also means localized messaging in German is essential for prospecting into this base.

Migration Patterns

The migration ratios reveal the direction of travel. 13,251 companies left for Cloudflare (a 3.6:1 loss ratio), 2,178 moved to Hostinger (12.3:1), and 2,510 chose Squarespace (4.6:1). Only GoDaddy shows net inflows to 1and1. A sign that the platform retains customers who prefer traditional hosting but can't compete for those wanting modern infrastructure. The Cloudflare exodus is the most significant: over 13,000 companies chose a CDN-first platform over traditional shared hosting, reflecting a broader market shift toward edge computing and performance-optimized delivery.

Sales Signal: The 13,251 companies that migrated to Cloudflare chose performance over loyalty. If you sell hosting, CDN, or website performance tools, the remaining 1and1 customer base contains companies that haven't yet made that jump, but the trend line suggests many will. Position your solution as the migration path they'll eventually take anyway.

"13,251 companies left 1and1 for Cloudflare at a 3.6:1 loss ratio, the single largest hosting migration pattern in our European dataset." - Mehmet Suleyman, CEO at TechnologyChecker.io

Technology Ecosystem

The tech stack analysis shows 95.49% of 1and1 customers also use IONOS products (DNS, email, hosting infrastructure). This tight bundling creates real vendor lock-in, customers who want to mix best-of-breed services can't easily do so within the IONOS ecosystem. On the positive side, SPF adoption runs at 93.48% and SSL by Default at 62.75%, showing the platform handles security fundamentals well. Apache (68.52%) and PHP (22.87%) usage reflects a traditional LAMP stack customer base, not the modern JAMstack or containerized deployments that newer hosting platforms target.

Sales Signal: If you're selling migration services, know that 1and1 customers are likely running Apache/PHP stacks on IONOS infrastructure with bundled DNS and email. Your migration playbook should account for the full IONOS bundle, not just hosting, but DNS, email, and SSL certificate provisioning.

G2 Review Signals

G2 review data for 1and1 is limited in volume, but directional. Users highlight ease of use and affordable pricing as standout features, while dashboard clutter surfaces as the most common criticism. The low review volume itself is telling. It suggests a customer base that doesn't actively evaluate alternatives or participate in review platforms, consistent with the micro-business, non-technical profile we see in our enrichment data. Our migration data provides stronger signals than G2 here: the 3.6:1 loss to Cloudflare and 12.3:1 loss to Hostinger tell you more about customer satisfaction than a handful of reviews ever could.

Sales Signal: Don't rely on G2 sentiment for 1and1 competitive positioning, the review volume is too low. Instead, use migration pattern data as your proxy for satisfaction: the directional losses to Cloudflare and Hostinger are the clearest indicators of where customer expectations aren't being met.

Key Takeaways

1. High churn, legacy base. 417,355 former customers vs. 387,287 active, more sites have left 1and1 than currently use it, signaling structural decline.

2. Micro-business dominated. 91.9% have 1-10 employees, with only 38 enterprises. This is a consumer-grade hosting platform by customer profile.

3. Germany-first distribution. 39.3% of customers are German, reflecting the platform's origins, competitors need German-language messaging to prospect effectively here.

4. IONOS lock-in is real. 95.49% run bundled IONOS products, creating multi-product switching costs that slow migration but don't prevent it.

5. Cloudflare is the primary migration destination. 13,251 companies switched at a 3.6:1 loss ratio, performance and modern CDN capabilities are pulling customers away.

Sales Applications

Outreach template: "Hi [Name], I noticed [Company] runs on 1and1/IONOS hosting with Apache. Our data shows 13,251 companies migrated from 1and1 to modern CDN-first platforms last year. And most saw [performance improvement]. Can I show you what [similar company] achieved by switching?"

Targeting strategy: Filter TechnologyChecker.io for 1and1 + Germany + Business Consulting/Construction + 1-50 employees to reach the core ICP: German micro-businesses running traditional LAMP stacks. For competitive displacement, filter 1and1 + no Cloudflare to find companies that haven't yet adopted CDN performance.

Competitive angle: The 2,178 companies that left for Hostinger at a 12.3:1 ratio chose pricing as the primary driver. If your platform offers competitive European hosting prices with better performance than 1and1, these price-sensitive micro-businesses are your highest-conversion segment.

Is IONOS the same as 1and1?

Yes, they're the same company. 1and1 rebranded to IONOS in 2018 after merging with ProfitBricks, and both brands operate under United Internet AG. Our technology detection still labels it as 1and1 because the underlying hosting infrastructure signatures haven't changed. Current customers see the IONOS branding, but the tech stack is identical.

Is 1and1 hosting good for small businesses?

It depends on what you need. Our data shows 91.9% of 1and1 customers have 1-10 employees, so the platform is clearly built for micro-businesses. However, migration data reveals significant churn. 13,251 companies left for Cloudflare Hosting and 2,178 moved to Hostinger, based on our enriched company analysis. Price-sensitive and performance-focused customers tend to leave for newer alternatives.

Which country is 1and1 from?

1and1 (now IONOS) was founded in Germany in 1988, in the city of Karlsruhe. It's owned by United Internet AG and remains headquartered there. Our data at TechnologyChecker.io reflects this origin clearly: 39.3% of all 1and1 customers are based in Germany, nearly triple the UK (14.5%) and US (14.4%) markets.

What industries use 1and1 the most?

Business Consulting and Services leads at 6.49% (4,936 companies), followed by Construction at 4.97% (3,781 companies) and Retail at 3.49%, per our analysis of 62,130 enriched companies at TechnologyChecker.io. No single industry exceeds 7%, making 1and1 a horizontal platform with no strong vertical specialization.

Is the 1and1 brand being phased out?

The brand is, but the infrastructure isn't. 1and1 rebranded to IONOS in 2018, and all new marketing uses the IONOS name. Our detection data still identifies it as 1and1 because the technical hosting signatures haven't changed. Existing customers continue on the same infrastructure without disruption, 95.49% of them also show IONOS products in their tech stack.

What is the difference between 1and1 and IONOS?

Technically, there's no difference. 1and1 and IONOS are the same hosting infrastructure operated by United Internet AG. The rebrand happened in 2018 after the ProfitBricks acquisition. Our tech stack data confirms this: 95.49% of 1and1 customers also run IONOS products (DNS, email, infrastructure), showing they're the same bundled community.

Why are companies leaving 1and1?

Price and performance are the main drivers. Our migration data at TechnologyChecker.io shows 13,251 companies switched to Cloudflare Hosting (a 3.6:1 loss ratio) and 2,178 moved to Hostinger (a 12.3:1 loss ratio). Cloudflare wins on speed and CDN capabilities; Hostinger wins on cost. These are among the worst migration ratios we track for mid-tier hosting providers.

What companies are switching to 1and1?

The largest inflow comes from GoDaddy. 3,880 companies switched to 1and1, based on our enriched company data. Smaller gains came from OVH (2,735 companies) and Unified Layer (1,175). However, these inflows don't offset the outflows to Cloudflare and Hostinger, resulting in a net negative migration trend overall.

Can enterprise companies use 1and1?

They can, but very few do. Only 0.04% of 1and1 customers, just 38 companies, have 10,001+ employees, based on our analysis of 62,130 enriched companies at TechnologyChecker.io. Those 38 include Honeywell, Roche, Bayer, and Deutsche Telekom. Most large companies use 1and1 for specific subdomains or internal tools, not their primary web infrastructure.
