ILLA Builder is a low-code development platform designed for developers who need to quickly create internal tools such as dashboards, CRUD applications, admin panels, and CMS systems without writing extensive frontend code. It solves the problem of slow internal tool development by providing pre-built components and data connectors that reduce development time from weeks to hours. Built with React and TypeScript, it supports self-hosting via Docker, docker-compose, and Kubernetes, and integrates with PostgreSQL, MySQL, MongoDB, REST APIs, Supabase, Hugging Face, and Redis.
The platform is open source (Apache 2.0) and offers real-time collaboration, automated workflows via webhooks and schedules, and a component library powered by ILLA Design. Users can visually build UIs, connect to data sources through a GUI, and deploy apps either on ILLA Cloud or self-hosted infrastructure.
What You Get
- Real-time Collaboration - Multiple developers can edit the same internal tool simultaneously with live updates, enabling team-based development of dashboards and admin panels.
- Automate Workflows with Webhooks & Schedules - Trigger actions or data updates automatically via scheduled jobs or incoming webhooks, enabling event-driven internal tool behavior.
- Self-hosted Deployment - Deploy ILLA Builder on-premises using Docker, docker-compose, or Kubernetes with full control over data and infrastructure.
- Drag-and-Drop UI Builder - Build interfaces using a library of components (tables, charts, forms, etc.) with automatic layout adjustment when elements overlap.
- Built-in Data Connectors - Connect to PostgreSQL, MySQL, MongoDB, MSSQL, Supabase, REST APIs, Hugging Face, and Redis through a graphical interface without writing code.
- Page-Based App Structure - Create content-rich, multi-page applications with navigation and state management, forming the foundation for complex internal tools.
Common Use Cases
- Building an internal CRM - A sales team uses ILLA Builder to create a custom CRM connected to their MySQL database, with forms for lead entry and charts for pipeline visualization.
- Developing an admin dashboard - A DevOps engineer builds a real-time monitoring dashboard that pulls data from Redis and REST APIs to track server health and deployment status.
- Creating a CMS for internal documentation - A product team designs a content-rich CMS with drag-and-drop components to manage and publish internal product specs and release notes.
- Automating HR onboarding workflows - An HR department connects ILLA Builder to their HRIS system via REST API to auto-generate onboarding checklists and send welcome emails via webhook triggers.
Under The Hood
Architecture
- Monorepo structure with Turbo and pnpm workspaces enabling efficient incremental builds and clear separation between UI applications and shared component libraries
- React-based component tree with explicit separation of concerns, using service layers and custom hooks to decouple UI from business logic
- Dependency injection via workspace-relative package exports, promoting reuse of core types and components across modules
- WebSocket communication abstracted with typed payload schemas, decoupling transport logic from UI state management
- Modular state management inferred from component props and localized i18n configurations, suggesting a unidirectional data flow without external state libraries
- Consistent TypeScript interfaces and Vite-based tooling with shared ESLint and Prettier configs enforcing type safety and code style
Tech Stack
- React 18 with TypeScript and Vite forming the core frontend stack, enhanced with SWC for fast builds and SSL support for secure development
- CodeMirror 6 integrated for advanced syntax highlighting and linting across multiple languages
- DnD Kit and Editor.js enable rich interactive editing experiences including drag-and-drop and rich text
- Nginx-based Docker deployment with Fly.io for automated cloud hosting, featuring static asset optimization and HTTPS enforcement
- Centralized internationalization via Crowdin and React-i18next, supported by Husky, Lint-staged, and Commitlint for code quality
Code Quality
- Extensive end-to-end test suite covering core workflows but plagued by duplicated setup/teardown logic and lack of reusable utilities
- Error handling is UI-centric, relying on visual assertions rather than programmatic validation or custom error types
- Inconsistent naming conventions across tests and components, reducing clarity and maintainability
- Type safety is inconsistently applied, particularly in environment variable usage
- Linting and code quality tooling appear underutilized, with repetitive code blocks and minimal abstraction in test files
What Makes It Unique
- Visual query builder enables dynamic data binding between UI and backend actions without manual code writing
- Extensible action panel system allows plugin-like integration of third-party services through dynamic UI rendering
- Runtime CSS-in-JS theming with customizable variables enables real-time, user-driven layout adjustments
- Drag-and-drop column manipulation with context-aware state allows non-technical users to modify data structures visually
- Unified WebSocket payload system supports real-time collaboration without external libraries
- Handlebars templates embedded in UI forms enable complex data transformations directly within the visual editor
