AI agent for building data apps, dashboards and reports
Preswald is an AI agent that helps you build dashboards, internal tools, and data apps. It gives you a fast, reactive runtime, built-in UI components (tables, charts, inputs), and one-click deployment to share your app in the cloud or browser.
Preswald enables building interactive reports with parameterized inputs, data tables with sorting and filtering, and offline-capable applications. Users can package apps for fieldwork or secure environments, and deliver reports that update based on user input without requiring code knowledge from end users.
Preswald lets users write Python code to create interactive dashboards with built-in support for Plotly, Matplotlib, and custom charts. Users can add interactive controls like sliders and dropdowns that automatically update visualizations, enabling rapid dashboard development using familiar Python skills.
Preswald runs entirely in the browser with data staying on the user's computer, making it ideal for sensitive data, air-gapped environments, and offline work. The application processes data locally using Python and DuckDB without transmitting information to external servers.
Preswald includes built-in chat components and AI-ready interfaces for natural language data exploration, allowing users to create conversational analytics applications. The platform is designed to work with AI agents, providing structured and inspectable tools for data analysis assistants.
Preswald exports applications as static sites that can be deployed to any hosting platform without backend servers. Users run `preswald export` to generate a complete static website, eliminating deployment complexity and allowing deployment to simple hosting services.
