Cloudflare Workflows vs Google Cloud Workflows

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.

Google Cloud Workflows is a managed orchestration platform for running Google Cloud services, custom services, and HTTP APIs in a chosen sequence. Workflow definitions use YAML or JSON and can combine ordered steps with conditions, loops, parallel work, and reusable subworkflows. Start an execution manually, through client libraries or REST, or on a schedule with Cloud Scheduler. Connectors link workflows to Google Cloud APIs such as Pub/Sub, Firestore, and Secret Manager, while workflow steps can also call custom or private HTTP and HTTPS endpoints. Reliability features include retries, polling, error handling, callbacks, and waits of up to one year. A single execution can run up to 100,000 steps and last no more than one year. IAM controls access; Secret Manager can store and retrieve secrets. Cloud Logging and Cloud Monitoring surface execution logs, volume, errors, and duration. Pricing is based on executed steps, including failed and retried steps, while idle workflows incur no charges. The free plan includes 5,000 internal and 2,000 external steps; paid usage starts at $0.01 per month, with rates that vary by step type and volume.
