Inngest

Inngest belongs in the catalog because it reflects a modern shape of workflow infrastructure: durable execution built around application code rather than heavyweight orchestration diagrams or separate workflow DSLs. Its documentation is clear that Inngest functions are durable, fault-tolerant, resumable, and step-based. That makes it especially relevant for teams building product workflows, background jobs, sync engines, agent pipelines, and long-running functions that still need to live close to application code.

Its pricing posture is also unusually transparent. The official pricing page currently shows a Hobby plan at $0 per month with 50,000 executions, 100,000 events, and 5 concurrent steps; a Pro plan starting at $75 per month with 1 million included executions and 100+ concurrent steps; and Enterprise as contact-sales with custom limits. The same page also publishes volume pricing for additional executions, which is a strong signal for editorial quality because buyers can reason about scale before they talk to sales.
