Inngest
What it is
Inngest orchestrates asynchronous code as durable functions for event-driven workflows, background jobs, and agents. Its execution steps handle retries, state, and recovery from failures, while traces show background jobs, agents, and events from trigger to completion. Flow controls manage concurrency and fairness when users compete for resources. Developers can use official open-source SDKs for TypeScript, Python, and Go, or the REST API. Functions can run wherever an app is hosted, and the service describes isolated sandboxes for testing changes as well as tools for scoring and comparing variants on production traffic. The Free plan includes 5 seats, 50k executions, 500k events ingested, and 24-hour trace history. Execution pauses when the included Free quota is reached until the account upgrades. Pro starts at $99 a month, billed starting at, with 15 seats and 7-day trace history. Inngest states it is SOC 2 Type II compliant and that its US-based databases are encrypted at rest, with application traffic protected by TLS/SSL in transit.
For and against
For
- Steps handle retries and failure recovery
- Traces follow work from trigger to completion
- SDKs are available for three languages
- Functions can run wherever an app is hosted
- Includes isolated sandboxes for testing changes
Against
- Free execution pauses when its quota is reached
- Free plan has 24-hour trace history
- Pro starts at $99 a month
The verdict
Inngest provides execution controls and observability for asynchronous code, with SDKs, an API, and deployment options. The Free plan has a usage threshold that pauses execution until an upgrade.
Who it suits
Inngest suits developers building event-driven workflows, background jobs, or agents who need durable execution and traces. Its SDKs and API support teams working in TypeScript, Python, or Go.
