IONOS

IONOS is an app creation tool. IONOS AI App & Site Builder converts chat prompts, voice notes or uploaded files into hosted websites and web apps, with manual text edits, credit-based AI changes, and domain, hosting, SSL and email bundled into the plan.

IONOS AI App & Site Builder is a no-code product from the German hosting company that turns a plain language description into a working website or web application. The starting point is a prompt typed into a chat, spoken aloud, or supplied as an uploaded file. The builder interprets the request and generates a project with pages, sections and interactive logic, so a booking tool, quote calculator, product configurator or internal dashboard can exist without anyone writing code. IONOS markets the approach as vibe coding: the AI handles the build, and the user stays focused on what the result should do rather than on how it is implemented. Revision works two ways. A user can describe a change in chat and watch it render in real time, or click directly into the project to edit text and small details by hand. That manual editing does not consume AI credits, which matters because prompt-driven work is metered. Credit costs scale with complexity: roughly one credit for a small text or color change, about two for a new page or section, and up to ten for a larger redesign. The page suggests 150 credits covers two to three pages built from scratch or around fifty individual tweaks. On Starter and Plus, AI building pauses when credits run out until the monthly reset; Unlimited removes the cap. Publishing is the part that separates IONOS from prompt-only builders. The product provisions hosting, a domain and an SSL certificate as part of the plan, and a single click puts the project live on IONOS infrastructure, which the company backs with a 99.99% uptime guarantee and DDoS protection. Sites and apps run without drawing credits while visitors use them. Email addresses are bundled in, and free domains are included for the first year. Those extras suit small businesses, agencies and independent operators who want one bill rather than a stack of subscriptions. It is best understood as a managed alternative to standalone AI app generators. You trade some freedom in hosting and stack choice for a complete setup and around the clock human support. The plan limits are worth reading closely: the FAQ lists the Unlimited tier at up to 25 sites or apps.
