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.

Routes chat requests through Vercel AI Gateway to multiple LLM providers (OpenAI, Anthropic, Google, etc.) with automatic provider selection and fallback logic. Implements server-side streaming via Next.js API routes that pipe model responses directly to the client using ReadableStream, enabling real-time token-by-token display without buffering entire responses. The /api/chat route integrates @ai-sdk/gateway for provider abstraction and @ai-sdk/react's useChat hook for client-side stream consumption.
Unique: Uses Vercel AI Gateway abstraction layer (lib/ai/providers.ts) to decouple provider-specific logic from chat route, enabling single-line provider swaps and automatic schema translation across OpenAI, Anthropic, and Google APIs without duplicating streaming infrastructure
vs alternatives: Faster provider switching than building custom adapters for each LLM because Vercel AI Gateway handles schema normalization server-side, and streaming is optimized for Next.js App Router with native ReadableStream support
Stores all chat messages, conversations, and metadata in PostgreSQL using Drizzle ORM for type-safe queries. The data layer (lib/db/queries.ts) provides functions like saveMessage(), getChatById(), and deleteChat() that handle CRUD operations with automatic timestamp tracking and user association. Messages are persisted after each API call, enabling chat resumption across sessions and browser refreshes without losing context.
Unique: Combines Drizzle ORM's type-safe schema definitions with Neon Serverless PostgreSQL for zero-ops database scaling, and integrates message persistence directly into the /api/chat route via middleware pattern, ensuring every response is durably stored before streaming to client
vs alternatives: More reliable than in-memory chat storage because messages survive server restarts, and faster than Firebase Realtime because PostgreSQL queries are optimized for sequential message retrieval with indexed userId and chatId columns
Rivet scores higher at 46/100 vs Vercel AI Chatbot at 40/100.

Search the match graph →© 2026 Unfragile. Stronger through disorder.
Displays a sidebar with the user's chat history, organized by recency or custom folders. The sidebar includes search functionality to filter chats by title or content, and quick actions to delete, rename, or archive chats. Chat list is fetched from PostgreSQL via getChatsByUserId() and cached in React state with optimistic updates. The sidebar is responsive and collapses on mobile via a toggle button.
Unique: Sidebar integrates chat list fetching with client-side search and optimistic updates, using React state to avoid unnecessary database queries while maintaining consistency with the server
vs alternatives: More responsive than server-side search because filtering happens instantly on the client, and simpler than folder-based organization because it uses a flat list with search instead of hierarchical navigation
Implements light/dark theme switching via Tailwind CSS dark mode class toggling and React Context for theme state persistence. The root layout (app/layout.tsx) provides a ThemeProvider that reads the user's preference from localStorage or system settings, and applies the 'dark' class to the HTML element. All UI components use Tailwind's dark: prefix for dark mode styles, and the theme toggle button updates the context and localStorage.
Unique: Uses Tailwind's built-in dark mode with class-based toggling and React Context for state management, avoiding custom CSS variables and keeping theme logic simple and maintainable
vs alternatives: Simpler than CSS-in-JS theming because Tailwind handles all dark mode styles declaratively, and faster than system-only detection because user preference is cached in localStorage
Provides inline actions on each message: copy to clipboard, regenerate AI response, delete message, or vote. These actions are implemented as buttons in the Message component that trigger API calls or client-side functions. Regenerate calls the /api/chat route with the same context but excluding the message being regenerated, forcing the model to produce a new response. Delete removes the message from the database and UI optimistically.
Unique: Integrates message actions directly into the message component with optimistic UI updates, and regenerate uses the same streaming infrastructure as initial responses, maintaining consistency in response handling
vs alternatives: More responsive than separate action menus because buttons are always visible, and faster than full conversation reload because regenerate only re-runs the model for the specific message
Implements dual authentication paths using NextAuth 5.0 with OAuth providers (GitHub, Google) and email/password registration. Guest users get temporary session tokens without account creation; registered users have persistent identities tied to PostgreSQL user records. Authentication middleware (middleware.ts) protects routes and injects userId into request context, enabling per-user chat isolation and rate limiting. Session state flows through next-auth/react hooks (useSession) to UI components.
Unique: Dual-mode auth (guest + registered) is implemented via NextAuth callbacks that conditionally create temporary vs persistent sessions, with guest mode using stateless JWT tokens and registered mode using database-backed sessions, all managed through a single middleware.ts file
vs alternatives: Simpler than custom OAuth implementation because NextAuth handles provider-specific flows and token refresh, and more flexible than Firebase Auth because guest mode doesn't require account creation while still enabling rate limiting via userId injection
Implements schema-based function calling where the AI model can invoke predefined tools (getWeather, createDocument, getSuggestions) by returning structured tool_use messages. The chat route parses tool calls, executes corresponding handler functions, and appends results back to the message stream. Tools are defined in lib/ai/tools.ts with JSON schemas that the model understands, enabling multi-turn conversations where the AI can fetch real-time data or trigger side effects without user intervention.
Unique: Tool definitions are co-located with handlers in lib/ai/tools.ts and automatically exposed to the model via Vercel AI SDK's tool registry, with built-in support for tool_use message parsing and result streaming back into the conversation without breaking the message flow
vs alternatives: More integrated than manual API calls because tools are first-class in the message protocol, and faster than separate API endpoints because tool results are streamed inline with model responses, reducing round-trips
Stores in-flight streaming responses in Redis with a TTL, enabling clients to resume incomplete message streams if the connection drops. When a stream is interrupted, the client sends the last received token offset, and the server retrieves the cached stream from Redis and resumes from that point. This is implemented in the /api/chat route using redis.get/set with keys like 'stream:{chatId}:{messageId}' and automatic cleanup via TTL expiration.
Unique: Integrates Redis caching directly into the streaming response pipeline, storing partial streams with automatic TTL expiration, and uses token offset-based resumption to avoid re-running model inference while maintaining message ordering guarantees
vs alternatives: More efficient than re-running the entire model request because only missing tokens are fetched, and simpler than client-side buffering because the server maintains the canonical stream state in Redis
