Provides a Tauri-based desktop application with a visual node-and-edge graph editor that allows users to design AI workflows by connecting nodes representing LLM calls, data transformations, and control flow. The editor uses a React-based UI component system that renders nodes with configurable input/output ports, supports drag-and-drop connections, and maintains real-time synchronization with the underlying graph data model. Graph state is persisted to disk as JSON and can be loaded for editing or execution.
Unique: Uses Tauri for native desktop delivery with React UI components, enabling local-first graph editing with native file system access and process execution capabilities without cloud dependency. Graph structure is decoupled from rendering, allowing the same graph definition to execute in desktop, CLI, or embedded Node.js contexts.
vs alternatives: Offers native desktop performance and local execution unlike web-based competitors (LangChain Studio, Flowise), while maintaining portability through a platform-agnostic core graph format that can be embedded in production applications.
Core execution engine (@ironclad/rivet-core) that interprets and executes directed acyclic graphs (DAGs) of nodes with support for local execution, remote debugging, and embedded programmatic execution. The processor handles node scheduling, data flow between connected nodes, context propagation, and execution recording. It supports three execution modes: local (in-process), remote (with debugger attachment), and embedded (via NPM packages). Execution state is tracked through a ProcessContext object that maintains variable bindings, execution history, and node outputs.
Unique: Implements a ProcessContext-based execution model that decouples graph definition from execution state, enabling the same graph to be executed multiple times with different inputs while maintaining isolated execution contexts. Supports both synchronous and asynchronous node execution with automatic dependency resolution based on graph connectivity.
vs alternatives: Provides tighter integration between visual design and programmatic execution than LangChain (which requires separate Python/JS code), while offering better debugging capabilities than Flowise through remote execution and execution recording.
Built-in nodes for common data processing tasks: JSON extraction (JSONPath queries), string manipulation (split, join, replace, regex), array operations (map, filter, reduce), and type conversion. These nodes operate on data flowing through the graph, enabling transformation of LLM outputs into structured formats. Nodes support chaining — output of one transformation node feeds into the next. Includes error handling for invalid JSON or malformed data.
Unique: Provides transformation nodes as first-class graph components rather than inline operations, enabling visual composition of data pipelines and reuse of transformation patterns across graphs. Transformation logic is declarative, making graphs more readable than code-based transformations.
vs alternatives: More visual than writing Python/JavaScript code for transformations. More composable than LangChain's OutputParser because transformations are graph nodes that can be reused and tested independently.
Nodes for implementing conditional logic (if/else based on boolean expressions) and loops (for-each over arrays, while loops with conditions). If nodes evaluate a condition and route execution to different branches. Loop nodes iterate over array elements, executing a subgraph for each element and collecting results. Merge nodes combine outputs from multiple branches. Control flow is explicit in the graph structure, making execution paths visible.
Unique: Implements control flow as explicit graph nodes rather than implicit language constructs, making execution paths visible and debuggable. Subgraphs within loops are full graphs, enabling complex nested workflows.
vs alternatives: More visual than code-based control flow (if/for statements). More flexible than LangChain's branching because control flow is data-driven and can be modified at runtime.
Automatically records execution traces during graph execution, capturing node inputs, outputs, execution time, and errors. Traces are stored in the execution context and can be inspected through the debugger or exported for analysis. Includes timing information for performance profiling and error details for debugging. Traces can be filtered by node, time range, or error status. Integration with monitoring systems allows traces to be sent to external observability platforms.
Unique: Records traces automatically without requiring explicit instrumentation, capturing complete execution history including intermediate node outputs. Traces are structured data, enabling programmatic analysis and integration with external monitoring systems.
vs alternatives: More comprehensive than print-based logging because it captures structured data for all nodes. More accessible than building custom instrumentation because recording is built-in.
Runtime type system that validates connections between nodes based on input/output port types. Each node declares input and output port types (string, number, object, array, etc.). The editor prevents invalid connections (e.g., connecting a string output to a number input) and provides type mismatch warnings. Type information is used for runtime validation and can inform UI decisions (e.g., showing only compatible nodes when creating connections).
Unique: Implements type validation at the graph editor level, providing immediate feedback when creating connections. Type information is declarative in node definitions, enabling the same type system to work across desktop, CLI, and embedded contexts.
vs alternatives: More user-friendly than code-based type systems because type errors are caught visually. More flexible than strict type systems because coercion is allowed for common cases.
Extensible architecture where nodes are registered plugins implementing a common interface (NodeDefinition, NodeImpl). The core library includes 40+ built-in nodes organized into categories: Chat/AI nodes (OpenAI, Anthropic, Ollama), Data Processing nodes (JSON extraction, string manipulation, array operations), Control Flow nodes (if/else, loops, merge), and MCP Integration nodes. Each node declares input/output port schemas, execution logic, and UI configuration. Custom nodes can be registered at runtime via the plugin system without modifying core code.
Unique: Uses a registry-based plugin pattern where nodes are first-class objects with declarative schemas for inputs/outputs, enabling the same node definition to work across desktop, CLI, and embedded execution contexts. Node execution logic is decoupled from UI rendering, allowing headless execution of graphs with custom nodes.
vs alternatives: More extensible than LangChain's tool-calling system because nodes are full workflow components with state management, not just function wrappers. Simpler than building custom LangChain agents because node registration is declarative and doesn't require agent framework knowledge.
Unified interface for integrating multiple LLM providers (OpenAI, Anthropic, Ollama, custom endpoints) through a model abstraction layer. Each provider has dedicated integration code handling authentication, request formatting, and response parsing. Chat nodes accept a model identifier and configuration object specifying temperature, max tokens, and provider-specific parameters. The abstraction allows graphs to switch providers by changing a single configuration value without modifying node logic. Supports streaming responses and token counting for cost estimation.
Unique: Implements provider abstraction at the node level rather than globally, allowing different nodes in the same graph to use different providers. Configuration is stored in graph definition, making provider changes reproducible and version-controllable without code changes.
vs alternatives: More flexible than LangChain's LLMChain because provider switching doesn't require code changes, and more transparent than Anthropic's Workbench because token usage is explicitly tracked and queryable.
