Executes multi-step workflows with automatic state checkpointing after each step, enabling resumption from failure points without re-executing completed steps. Uses Redis-backed state management with Lua scripts for atomic queue operations and checkpoint persistence. Steps are defined declaratively and executed sequentially with full execution history tracking via CQRS event storage.
Unique: Implements checkpoint-based durability via Redis Lua scripts for atomic state transitions, combined with CQRS event sourcing for full execution history. Unlike simple job queues, each step's completion is persisted atomically, enabling true resumption without re-execution or duplicate work.
vs alternatives: Provides true durability without requiring distributed consensus (vs Temporal/Cadence) while maintaining simpler operational overhead than full workflow orchestration platforms.
Triggers workflow execution based on incoming events matched against declarative trigger patterns defined in CUE configuration. Events are ingested via REST API or SDK, normalized, and matched against registered function triggers using pattern matching logic. Supports event filtering, batching, and fan-out to multiple workflows from a single event.
Unique: Uses CUE-based declarative trigger configuration for type-safe event matching, combined with Redis-backed event queue for reliable delivery. Trigger patterns are compiled into efficient matching logic rather than interpreted at runtime, reducing latency.
vs alternatives: Simpler trigger definition than Temporal/Cadence (no code-based trigger logic) while supporting more complex patterns than simple queue-based systems through CUE schema validation.
Exposes workflow execution data and operations via GraphQL API, enabling flexible querying of executions, functions, and traces. Supports filtering, pagination, and aggregation. Mutations enable triggering executions, canceling runs, and managing function configurations. Uses DataLoader pattern for efficient batch loading to prevent N+1 queries.
Unique: Provides GraphQL API with DataLoader-based batch loading for efficient querying of execution data. Supports complex filtering and aggregation without requiring multiple API calls.
vs alternatives: More flexible than REST API (supports complex queries) while remaining simpler than building custom query engines.

vs alternatives: More integrated than external monitoring tools (built into Inngest) while remaining simpler than full observability platforms.
Enables parallel execution of multiple steps using fan-out pattern, where a single step spawns multiple child executions. Fan-in collects results from all child executions and passes them to subsequent steps. Implemented via step functions that return arrays of execution requests. Supports dynamic fan-out based on runtime data.
Unique: Implements fan-out/fan-in as step-level primitives, allowing dynamic parallelism based on runtime data. Child executions are tracked and their results collected automatically by the execution engine.
vs alternatives: Simpler than implementing custom parallel execution logic while supporting more dynamic patterns than fixed-size thread pools.

Supports scaffolding function templates, validating CUE schemas, and generating SDK code. Integrates with version control for tracking function changes.
Unique: Provides integrated CLI with function scaffolding, schema validation, and deployment capabilities. CLI uses same execution engine as production, ensuring behavior parity.
vs alternatives: More integrated than generic deployment tools (understands Inngest-specific concepts) while remaining simpler than full infrastructure-as-code frameworks.
Provides SDKs for multiple languages (Node.js, Python, Go, etc.) with automatic type generation from CUE schemas. SDKs handle HTTP communication with execution engine, request signing, response validation, and error handling. Generated types ensure type safety across language boundaries.
Unique: Provides SDKs for multiple languages with automatic type generation from CUE schemas. SDKs use standardized HTTP protocol for communication, enabling polyglot workflows.
vs alternatives: More comprehensive than language-specific libraries (supports multiple languages) while remaining simpler than full polyglot orchestration platforms.
Automatically retries failed steps using configurable exponential backoff with jitter to prevent thundering herd. Retry logic is built into the execution engine and applied transparently across all step types. Supports max retry counts, custom backoff curves, and retry-specific error classification (retryable vs permanent failures).
Unique: Implements exponential backoff with cryptographically-secure jitter at the execution engine level, avoiding retry storms through Redis-based lease management. Retry state is persisted in checkpoints, enabling retries to survive process restarts.
vs alternatives: More sophisticated than simple retry loops in application code (prevents thundering herd) while remaining simpler to configure than custom circuit breaker implementations.

Automatically loads and parses documents from diverse sources (PDFs, Word docs, HTML, Markdown, code files, databases) into a unified in-memory representation using format-specific loaders and node-based document abstractions. Each document is decomposed into Document objects containing metadata, content, and relationships, enabling downstream processing without format-specific handling in application code.
Unique: Provides a unified loader abstraction (BaseReader interface) that normalizes 100+ data source connectors into a single Document/Node API, eliminating format-specific branching logic in application code. Loaders are composable and chainable, allowing sequential transformations (e.g., load → split → extract metadata → embed).
vs alternatives: Broader out-of-the-box loader coverage than LangChain's document loaders and more structured node-based decomposition than raw text splitting, reducing boilerplate for multi-source RAG pipelines.
Splits documents into semantically coherent chunks using multiple strategies (character-based, token-aware, recursive, semantic) with configurable overlap and chunk size. Preserves document hierarchy and metadata through a node tree structure, enabling retrieval systems to maintain context relationships and enable hierarchical re-ranking or parent-document retrieval patterns.
Unique: Implements a node-tree abstraction that preserves document hierarchy and enables parent-document retrieval patterns. Supports multiple splitting strategies (recursive, semantic, code-aware) with pluggable custom splitters, and automatically propagates metadata through the node tree.
vs alternatives: More sophisticated than LangChain's text splitters because it preserves hierarchical relationships and supports semantic splitting; better for complex document structures than simple character-based splitting.
Inngest scores higher at 58/100 vs LlamaIndex at 40/100. Inngest also has a free tier, making it more accessible.
