Progressive Web App (PWA)
Definition and Core Browser Technologies
A Progressive Web App (PWA) is a web application engineered with standard web technologies (HTML, CSS, TypeScript, Service Workers, and a Web App Manifest) that runs in any browser while offering native-like capabilities such as home-screen installation, background asset caching, and offline resilience.
We architect PWA-enabled web portals starting from €9,000 for field-service, logistics, and B2B client self-service teams. Read our PWA guide for B2B.
Why B2B Enterprises Choose PWAs Over Native Apps
Maintaining separate iOS, Android, and web codebases triples engineering cost and delays releases via App Store approvals. A Next.js PWA shares a single codebase, deploys instantaneously, and reduces 3-year total cost of ownership by 55% to 65%.
Combine PWA capabilities with server-side rendering, schema markup, and a secure web portal architecture.

Knowledge Base
Schema Markup (JSON-LD Structured Data)
→Standardized Schema.org JSON-LD code embedded in web pages that explicitly defines organizations, services, FAQs, and articles for Google and AI engines.
Schema.org JSON-LD @graph & Entity Linking
→Semantic SEO architecture that connects multiple Schema.org entities on a page into a single unified knowledge graph using persistent @id URI references.
Server-Side Rendering (SSR)
→A web rendering architecture where complete HTML is generated on the server before reaching the browser, ensuring instant indexing by Google and AI bots.
Server-Side Tagging (sGTM)
→First-party analytics architecture that routes conversion events through an owned cloud proxy instead of loading heavy third-party JavaScript tags in the browser.
Single Sign-On (SSO) & Role-Based Access Control (RBAC)
→Enterprise authentication and authorization standards (SAML 2.0, OIDC, RBAC) that govern multi-tenant user permissions inside B2B web portals.
Stale-While-Revalidate (SWR) Edge Caching
→HTTP RFC 5861 caching directive and React data-fetching strategy that serves cached responses immediately while asynchronously updating fresh data in the background.
