Aspen

Drag-and-drop interface for constructing generative AI web applications without writing boilerplate code. Users can visually compose components, connect LLM integrations, and define application logic through a graphical interface.

Pre-built connectors and abstractions for popular LLMs (GPT, Claude) that handle authentication, API calls, and response parsing. Developers can integrate LLM capabilities without managing API credentials or request/response formatting.

System for managing configuration variables and secrets across different deployment environments without hardcoding them. Developers can define environment-specific configurations for API keys, LLM settings, and other parameters.

Built-in monitoring and analytics for tracking application performance, user interactions, and LLM usage metrics. Developers can view dashboards showing application health, usage patterns, and cost metrics without external tools.

Integration with Git and version control systems allowing developers to track changes to their AI applications, collaborate with team members, and manage application versions. Application code can be committed and managed like traditional software projects.

Built-in testing and preview capabilities allowing developers to test applications before deployment. Developers can preview changes, test LLM integrations, and validate application behavior without affecting production.

Dual-mode editing environment allowing developers to switch between visual component building and direct code editing. Developers can use the visual builder for rapid prototyping and drop into code for fine-grained control when needed.

Automated deployment infrastructure that handles hosting, scaling, and DevOps without requiring manual configuration. Applications built in Aspen can be deployed directly from the platform with minimal additional setup.

Collection of ready-made UI and functional components specifically designed for AI applications, including prompt inputs, response displays, and common AI workflow patterns. Components can be dragged into applications and configured without building from scratch.

Built-in user authentication and authorization system that handles login, session management, and access control without requiring custom implementation. Developers can add user authentication to their AI apps through platform features.

System for creating, storing, and versioning prompt templates that can be reused across the application. Developers can define parameterized prompts and manage variations without hardcoding them into application logic.

Framework for connecting UI components to application state and data sources, enabling reactive updates without manual state synchronization. Developers can bind components to data and define how changes propagate through the application.

Tool for connecting external APIs and data sources to AI applications without writing integration code. Developers can configure API endpoints, handle authentication, and map responses to application components.

Built-in system for capturing, logging, and handling errors in AI applications. Developers can configure error handling rules and access logs for debugging without implementing custom logging infrastructure.
