Prismaliser is a fully client-side single-page application that visualizes Prisma database schemas as interactive entity-relationship diagrams. It runs entirely in the browser: the user pastes a Prisma schema into a Monaco editor, the app parses it client-side via a vendored WASM module from Prisma's own schema parser, and renders the models, enums, and relations (1-1, 1-n, m-n) as an interactive React Flow graph. The app has no backend server – it is a static Vite SPA that can be self-hosted (Docker image provided). Recently, AT Protocol (Bluesky) integration was added allowing users to publish immutable snapshots of their diagrams (schema + node positions) to their own AT repository, share via canonical AT links, and manage published snapshots. OAuth login is browser-native using the atcute library family. The codebase is TypeScript strict, thoroughly tested (Vitest), and follows modern React patterns with Tailwind CSS v4 and CSS modules. The architecture is modular: a util layer handles Prisma parsing, graph generation, and layout (elkjs), while a dedicated atproto/ module handles OAuth, record creation, public retrieval, and share link parsing. The UI is built with React 19, using local state and hooks (no global state management). The project is actively maintained with recent commits and open issue triage.
