Inngest vs Knative

Inngest runs asynchronous code as durable functions for event-driven workflows, background jobs, and agents. Its execution steps handle retries, retain state, and recover from failures; traces show activity from trigger to completion. Flow controls manage concurrency and fairness when users compete for resources. Developers can use open-source SDKs for TypeScript, Python, and Go, or the REST API. Functions can run wherever an app is hosted, with deployment guides for services including Vercel, Netlify, Cloudflare Pages, Render, and DigitalOcean. Inngest also describes isolated sandboxes for testing changes and 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 free quota is reached until the account upgrades. Pro starts at $99/mo. Inngest states that it is SOC 2 Type II compliant, and that its US-based databases are encrypted at rest and application traffic uses TLS/SSL in transit.

Knative is open-source Kubernetes middleware for building, deploying, and managing serverless workloads. Knative Serving handles stateless HTTP services, including deployment, routing, and automatic scaling. Services can scale from zero when idle and rise again with incoming traffic. Serving also supports blue-green deployments, canary releases, and traffic splitting between revisions. Knative Eventing routes asynchronous events through CloudEvents over HTTP. Knative Functions provides a framework for packaging stateless functions as containers. Installation can use a local quickstart or a production setup on an existing Kubernetes cluster with YAML or the Knative Operator. The project runs on Kubernetes across cloud providers and on-premises environments, with Linux, macOS, and Windows listed for installation. Integrations include Istio, Contour, Gateway API, Kafka, RabbitMQ, and NATS. The open-source plan is free, with self-managed Kubernetes deployment.
