What Inngest does
Inngest is a developer platform for building durable workflows and AI agents, founded in 2021 and headquartered in San Francisco. The company's core offering collapses event-driven infrastructure complexity — queues, pubsub, idempotency, error handling, and capacity management — into API calls embedded directly in the developer's codebase through TypeScript, Python, and Go SDKs. Its durable execution engine enables functions to persist state across invocations, retry from individual steps rather than restart, pause mid-execution and resume, and survive timeouts, failures, and deploys, while providing step-level observability and bulk replay capabilities. The platform supports AI agent workloads specifically through pause/resume semantics, multi-tenant concurrency control, and durable HTTP via step.fetch() that integrates with AI SDKs, complemented by AgentKit and a Dev Server MCP for AI coding agent integration.
Inngest operates a freemium SaaS model with a free tier for development and small-scale usage on app.inngest.com, plus a quote-based enterprise tier offering SOC 2 Type II compliance, HIPAA BAA, SAML SSO, end-to-end encryption, and 100K+ executions per second throughput. The go-to-market is hybrid: self-serve product-led growth through open-source SDKs (6.9K GitHub stars) and comprehensive documentation, layered with enterprise field sales targeting regulated industries. Named customers span AI (Cohere, ElevenLabs, Day AI, Otto), developer tools (Replit, Resend, GitBook), media (Soundcloud), and travel (Tripadvisor), with Cohere publicly attributing the platform to enabling AI orchestration scaling that would otherwise have taken a month of custom engineering. The company has raised $27.1M to date across a $6.1M seed (January 2024, led by a16z) and a $21M Series A (September 2025, led by Altimeter), positioning AI workflow automation as the explicit growth wedge.

Inngest product offering
Product offeringCore offering
Inngest provides a developer platform for durable execution of workflows and AI agents. It moves durability from infrastructure into the codebase, so functions automatically retry at the step level, pause and resume mid-execution, and survive failures, deploys, and timeouts. The platform collapses queues, pubsub, idempotency, scheduling, and error handling into simple SDK primitives (step.run, step.waitForEvent, step.invoke, step.ai.infer), and ships SDKs for TypeScript, Python, and Go, plus a CLI and Dev Server MCP for local development.
Product overview
Inngest is a unified developer platform for durable execution of workflows and AI agents. The core Inngest Platform provides reliability and observability for modern applications, collapsing event-driven complexity into developer-friendly APIs. The platform is complemented by multi-language SDKs (TypeScript v3/v4, Python, Go), the Inngest CLI for terminal-based debugging, the Dev Server for local development, and the Inngest Dashboard for production monitoring. AI-specific tooling includes AgentKit for agent orchestration and a Dev Server MCP for AI coding agent integration. The platform's architecture enables step-level retry control, flow management (concurrency, throttling, debounce), and full execution tracing without requiring new infrastructure.

Products and services
- Inngest Platform Cloud-hosted durable execution platform for workflows and AI agents. Provides step-level retries, pause/resume, event-driven triggers, flow control, observability, and SDKs for TypeScript, Python, and Go. Targeted at software engineering and platform teams.
- Inngest CLI Command-line tool for running, developing, and inspecting Inngest functions locally and against the platform. Used by developers to scaffold projects, run the dev server, and debug durable workflows.
- TypeScript SDK Official TypeScript SDK that lets developers define Inngest functions using step primitives (step.run, step.waitForEvent, step.invoke, step.sleep) and send events to trigger durable workflows.
- Python SDK Official Python SDK for defining durable Inngest functions and endpoints in Python applications, exposing the same step and event-driven primitives as the TypeScript SDK.
- Go SDK Official Go SDK for building durable Inngest functions and event-driven workflows in Go services.
- AgentKit Standalone toolkit (agentkit.inngest.com) for building production AI agents on top of Inngest's durable execution primitives, with tooling for multi-step agent workflows.
- Dev Server MCP Model Context Protocol server for the local Inngest dev server, enabling AI assistants and other MCP clients to interact with locally running Inngest functions.

Inngest competitors and assessment
Company assessmentDirect peers
- Temporal Technologies: Temporal is the leading durable execution platform, offering workflow-as-code primitives (activities, timers, retries) that directly mirror Inngest's step-based model. It is the most direct head-to-head competitor in the durable execution category.
- Trigger.dev: Trigger.dev provides a developer-first background jobs and workflows platform with SDK-based job definitions, retry controls, and observability. Targets the same PLG developer persona building AI agents and event-driven apps as Inngest.
- Restate: Restate is a durable execution and workflow orchestration platform built on virtual actors and sagas, offering step-level retries and replayable functions. Competes in the same developer workflow reliability niche as Inngest.
- Prefect: Prefect is a Python-first workflow orchestration platform offering durable flows, retries, and observability aimed at data and ML engineering teams. Overlaps with Inngest's Python SDK and AI orchestration positioning.
Emerging players
- Hatchet: Hatchet is an emerging open-source distributed task queue and workflow engine focused on background jobs with concurrency, retries, and scheduling primitives. Targets developer-platform use cases overlapping with Inngest's queue and cron offerings.
- Hookdeck: Hookdeck provides webhook and event ingestion infrastructure with retries, queuing, and observability. Competes on adjacent primitives (event handling, retries) that Inngest bundles into its durable execution platform.
Broad incumbents
- AWS Step Functions: AWS Step Functions is the hyperscaler's managed durable workflow service, deeply integrated with Lambda and the AWS ecosystem. Represents the bundling risk Inngest competes against for enterprise cloud-native customers.
- Azure Durable Functions: Azure Durable Functions is Microsoft's serverless durable execution extension to Azure Functions, offering orchestrator functions with pause/resume and replay semantics. Competes with Inngest for Microsoft-centric enterprise workloads.
- Google Cloud Workflows: Google Cloud Workflows is GCP's managed orchestration service combining HTTP calls and connectors into durable sequences. Bundled offering that competes for AI/agent workloads running on Google Cloud.
- Inngest (self-comparison not used); Cloudflare Workers with Durable Objects: Cloudflare Workers' Durable Objects provide strongly consistent, long-lived execution with persistence at the edge, competing with Inngest's durability-on-top-of-existing-code model for performance-sensitive and edge workloads.
