When a queue isn't enough
3/25/2026
Queuing and durable execution are two layers of the same problem. In this post we’ll look at solutions dedicated to each, and when each are most appropriate for what you’re building.
Node.js worker threads are problematic, but they work great for us
3/18/2026
Worker threads solve real problems, but they come with constraints that Go, Rust, and Python developers would never expect. Here's what we learned moving Inngest Connect's internals off the main thread.
Eliminating latency in AI workflows: How to avoid the durability tradeoff
2/25/2026
Every durable execution system adds some latency between steps. It's the tax we pay for reliability. Here's how to eliminate it.
How to Build a Production AI Image Generation Pipeline with fal.ai and Inngest
3/24/2026
fal.ai runs hundreds of models at scale. Inngest orchestrates the workflow around them — retries, async coordination, per-user fairness, and observability. Here's how the two work together to build a full media pipeline.
How to Build a Durable AI Agent with Inngest
3/17/2026
Use Inngest's step primitives to build resilient, observable AI agents without a heavyweight framework.
User Built: How Windmill Built a Durable Internal Ops Agent with Inngest
3/17/2026
How Windmill replaced brittle n8n flows with a durable internal ops agent—Pim—powered by Inngest Connect, context-first design, and a focused toolset.
How We Cut Redis Read Operations by 67% with a Stateful Caching Proxy
3/10/2026
We reduced pressure on our sharded Redis cluster by introducing a gRPC proxy that caches immutable run state and routes consistently by run ID.
Your Agent Needs a Harness, Not a Framework
3/3/2026
Agent runtimes don't need yet another framework — they need a durable, event-driven harness that connects tools, memory, and models on production-grade infrastructure.
Sharding high-throughput Redis without downtime
7/23/2024
Read about how we rolled our new sharded infrastructure out to production without a millisecond of downtime and how it improved Inngest's overall performance.
The Principles of Durable Execution Explained

Learn what Durable Execution is, how it works, and why it's beneficial to your system.
step.ai: the quickest way to build reliable AI applications on Serverless while saving on compute
12/10/2024
Combining step.run() and step.ai.infer() is the best toolset to build reliable AI applications on Serverless while saving on compute.
October 2024 queue retrospective
11/7/2024
Summary of the queue related issues in October 2024
How we built Insights AI with Inngest
1/15/2026
How we shipped Insights AI, what we learned about building agentic features, and why dogfooding your own infrastructure actually works.
Durable Execution: The Key to Harnessing AI Agents in Production
2/19/2026
AI Agents introduce multiple points of failure that traditional retry logic cannot handle. Durable execution provides the automatic state persistence, retries, and workflow resumption that make agents production-ready.
How to Fix Next.js AI Route Failures (Without Restarting from Zero)
3/9/2026
Add step-level durability to your Next.js AI routes so failures don't restart from zero—each step is independently retryable and memoized.
How we built a fair multi-tenant queuing system

Building the Inngest queue - Part I
The Constraint API: Scaling flow control beyond millions of RPS
2/23/2026
How we extracted constraint enforcement into a dedicated service to unlock lower latency, greater scalability, and flow control for Durable Endpoints.
October 2025 incident report

Summary of the incident that caused function execution to fail on October 24, 2025
Explicit APIs vs Magic Directives
10/24/2025
Comparing explicit APIs vs magic directives for workflows, queues, and durable execution. Or, directives as an antipattern.
5 Lessons Learned From Taking Next.js App Router to Production
5/5/2023
What did we learn from building and shipping our new app with the Next.js 13 App Router?
How we used Inngest Queues to build Inngest's native Cron Scheduler
3/20/2026
How we improved reliability of our cron scheduler by rebuilding it on top of our own durable queue primitives.
Typescript For Apps Vs Typescript For SDKs
3/13/2026
I thought I was good at TypeScript. Refactoring the Inngest SDK proved I was okay at best—and that changed how I think about types forever.
Reducing local dev time by 83%: Why we migrated off Next.js
1/30/2026
We care a lot about developer experience. But it's hard to build beautiful experiences for customers, while grinding through 10-12 second page load times. Here's how—and why—our team migrated from Next.js to Tanstack Start.
