Inngest simplifies backend development with tools for retries, concurrency, error handling, and state management.
What is Inngest?
Inngest is a developer platform that allows users to build powerful products without the complexity of managing infrastructure around queues, concurrency, retries, error handling, prioritization, and more. It provides tools for handling complex text-generation, leveraging Retrieval Augmented Generation (RAG) through querying vector stores, building ingestion functions, and maintaining state across workflows. Inngest offers features like automatic retries, durable sleep, managing concurrency, throttle, rate limit, or debounce, declarative job cancellation, custom failure handlers, pausing functions for additional input, batching for high load, and replay functions. It is designed to work with any backend and has received positive feedback from developers for its efficiency, clear messaging, ease of use, and stability.
Who created Inngest?
Inngest Overview:
Founder: Inngest was founded by Tony Holdstock-Brown, who currently serves as the CEO and Founder of the company.
Company Details: Inngest is a developer platform designed to simplify the process of building and managing reliable workflows with zero infrastructure. The platform aims to alleviate the time-consuming and frustrating experience of shipping background jobs and workflows for software teams of varying sizes and levels of experience. Inngest's core is open source, providing peace of mind to developers. The company recently raised $6.1 million in funding led by a16z. In addition to the founder, the team includes key members such as Dan Farrelly (CTO & Founder), Jack Williams (Founding Engineer), and other engineers, designers, and developers. The company has also garnered support from notable investors in the tech industry.

How to use Inngest?
To use Inngest, follow these steps:
-
Build Powerful Products: Get your LLM apps running without the complexity of additional infrastructure and manage complex text generation efficiently.
-
Handle Complex Text-Generation: Utilize chain-based post-processing and leverage Retrieval Augmented Generation (RAG) by querying vector stores and creating ingestion functions.
-
Wrap Steps: Run functions once and maintain state without managing data or queues manually. Limit concurrency and prioritize jobs to streamline workflow.
-
Ensure Reliability: Benefit from automatic retries for each function step, durable sleep options, and the ability to manage concurrency effectively.
-
Customize Functionality: Set custom concurrency limits, throttle, rate limit, or debounce functions, and manage job cancellations and failure handling seamlessly.
-
Enhance Functionality: Pause functions for additional input, batch for high load situations, and easily replay functions as needed for improved performance.
-
Estimate Steps: Based on the volume of messages processed in queues and cron jobs, estimate the step usage accordingly.
-
Technical Support: Choose from different support plans offering various features based on your team's needs, including SLAs, dedicated slack channels, integrations, and compliance options.
By following these steps, you can effectively utilize Inngest for seamless and reliable backend workflows.
Inngest FAQs
-
What is a 'step'?
- Steps are building blocks for logic in functions. They are individually retried, and only run once on success. They allow you to easily write complex logic in a single function.
-
How can I estimate steps?
- You can use the volume of messages that you currently process in your queues to approximate your step usage. Additionally, add the number of cron jobs that you run if you aim to use Inngest for scheduling.
-
What's a 'function'?
- A function is defined with the Inngest SDK using createFunction or similar. A function can be triggered by an event or run on a schedule (cron). Functions can contain multiple 'steps' to reliably run parts of your function or add functionality like sleeping/pausing a function for a period of time.
-
How are my functions run?
- Your functions are hosted in your existing application on any platform. They are called securely via HTTP request on-demand, with each function step called as a separate HTTP request.
-
What are concurrency limits?
- As Inngest runs your function any time an event is received, you may have any number of events received within a short period of time. Inngest can run all of these functions concurrently. The free tier allows for up to a specific number of concurrent functions.
-
Can I get a demo of the product?
- Yes! Inngest offers product demos to understand your team's needs. Contact them to set up a call.
-
What languages do you support?
- Inngest currently has SDKs for JavaScript/TypeScript, Python, and Go, with additional SDKs in development. You can view, upvote, and contribute to the development of SDKs for other languages on their public roadmap.
