IONOS

Builder with email, booking and store versions from IONOS

Overview

IONOS is the hosting and cloud business of the German United Internet group, which W3Techs counts as the hosting parent of 2.5% of all websites, the largest share of any European provider.[1] IONOS Group’s investor relations page reports revenue of EUR 1,317 million for 2025 and 6.63 million customers.[5]

IONOS’s US web hosting plans are sold on one-year terms with introductory pricing. In November 2026 the page listed Essential at US$4 per month (renewing at US$8), Starter at US$6 (renewing at US$10), Plus at a promotional US$1 per month (renewing at US$14) and Ultimate at US$10 (renewing at US$18).[6] Storage is generous by shared-hosting standards, from 100 GB of NVMe on Essential to 500 GB on Ultimate, and each plan includes a set number of email addresses and a malware scanner; the higher plans add a CDN and, on Ultimate, unlimited wildcard SSL certificates.[6]

IONOS is also a large domain registrar and sells VPS, dedicated servers, a website builder and Microsoft 365 bundles, which makes it a one-stop provider for small businesses in Europe and North America. Its web hosting plans quote server resources as relative multiples (‘1x’, ‘3x’ access) rather than CPU and memory figures, which makes like-for-like comparisons harder, and promotional prices vary between plans in ways that change frequently.
