The CTXR platform can — next to a traditional, full-featured Content Management System — also be managed by a modern AI agent. You describe what should change — a route, a point of interest, a piece of copy — in plain language, and the change lands correctly in the underlying structured data.
Managing content this way isn't just more convenient: because there's no plugin layer to exploit and every change lands directly in structured data, it's also safer. And because every page is built directly from that structured data, a CTXR site is naturally more findable for both search engines and AI assistants.
This is part of a broader shift we call Agentic Experience (AX) — read more about what that means.
CTXR is one of the most modern platforms for sharing information online: from place marketing to company presentations. Structured, highly findable, built on open standards, privacy by design and ready for every medium. CTXR was born out of location-based experiences — routes, places and place-lists on interactive maps — and is exceptionally strong at that, but it can do much more. It is built for municipalities and cultural organisations, tourism and local businesses, makers, developers and agencies.
Yes. The Sandbox is free: your own CTXR subdomain, 75 Pages & POI's, one user, 50 MB of fast storage and 5 API keys, with a small CTXR mark. When you need more, you can upgrade from within your own site.
The Sandbox is free. Developer is €29 per month (€225 per year), Professional is €49 per month (€380 per year) and Business+ starts at €99 per month (€770 per year), with a plan tailored to your use case, goals and team size. Capacity grows with each plan: 150, 300 and 600+ Pages & POI's, 3, 5 and 10+ users, and 100, 150 and 200+ MB of fast storage.
Every plan includes the full set of development tools, cross-device deployment, unlimited projects, the standard CMS, the option to connect your own AI agent, and 5 API keys per seat.
You request your own subdomain (yourname.ctxr.app) in a few short steps: your e-mail address, the address you want, a name for your site, a plan and the language of your site (English, Dutch, German or French). We then review your request and set it up — it doesn't go live instantly. As soon as it's ready, you receive access by e-mail.
No technical skills are needed. You manage your content in the standard CMS, which is always included. You can optionally connect your own AI agent and make changes by describing them in plain language — an addition, not a replacement. A comprehensive tech guide is available on GitHub.
Sandbox and Developer sites run on a CTXR subdomain and carry a small CTXR mark. Professional and Business+ add your own branding and your own domains.
Your visitors get a fast, app-like PWA straight from the browser — no app store and nothing to download, and content that keeps working offline once it is cached. Privacy comes first: CTXR is built with privacy by design, active tracking is not required in standard deployments, and accounts and data are handled in a GDPR-compliant way. Security is built in too: there is no database and no plugin layer to attack, and access runs through a single, controlled point. And everyone reads in their own language: sites are multilingual (English, Dutch, German and French), with audio (text-to-speech) so content can be listened to as well as read.
CTXR runs on European hosting. Access is centralised through a Single Point of Access (SPoA), with role-based admin controls, logging and GDPR-compliant account management. We build with privacy by design: active tracking is not required in standard deployments.
CTXR runs on the LOAM engine: your content is stored as structured JSON files based on Schema.org — no database and no plugin layer to attack. Every page is built directly from that structured data, which makes a site naturally easier to find for search engines and AI assistants. Open standards and interfaces include Schema.org/JSON, GeoJSON, REST APIs and MCP.
Yes. CTXR is designed for direct integration with the Open Urban Platform (OUP: 3D-tiles and geodata) and other platforms, including AI platforms, through open APIs. POI feedback can be passed back to municipal systems. For larger needs there are options such as dedicated instances, SSO, higher quotas and standalone packaging for offline or private deployments.
A typical pilot — technical prep, AI enrichment, backend and frontend work, testing — is scoped to deliver an initial monuments/POI layer within weeks. A full monument layer within a two-month window is realistic.
