Cloudflare Workflows vs Inngest

Cloudflare Workflows lets developers build durable, multi-step applications on Cloudflare Workers without managing infrastructure. It automatically retries failed tasks, handles errors, and preserves state for minutes, hours, or weeks. Workflows can pause for seconds, hours, or days, or wait for webhooks, user input, or external system responses before continuing. Instances may be triggered, paused, resumed, or terminated through code or an API. A workflow can call Fetch API requests and Cloudflare services including R2, KV, and D1, and can be invoked through the Workers API, Wrangler CLI, or REST API. Billing covers CPU time, requests, persisted storage, and executed steps; waiting or sleeping does not incur CPU time. Workers Free includes a free plan with usage limits, while paid pricing starts at $5/mo. Paid plans allow up to five minutes of CPU time per invocation. The service has a cloud deployment model, supports human tasks and approvals, long-running workflows, versioning, and up to 50,000 concurrent runs. Workflows cannot be deployed to Workers for Platforms namespaces.

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.
