Limitations & when to consider alternatives
Known limitations
- Free-plan payload limits. The Free plan supports a maximum single event size of 256 KiB.
- Function state size. Function run state cannot exceed 32 MiB, including event data, step data, return data, and metadata.
- Steps per function. A function can contain at most 1,000 steps; loops that create one step per item can reach this limit quickly.
- Step timeout. Inngest supports step timeouts up to two hours, subject to the limits of the hosting provider.
- Connect runtime requirements. The Connect API requires a long-running server; serverless runtimes such as AWS Lambda and Vercel are not supported for Connect workers.
Look elsewhere when
- You need a native mobile application.
- You need built-in image understanding.
- You need built-in fine-tuning or model training.
