Azure Durable Functions vs Dapr

Azure Durable Functions has no write-up on Specifiction yet; its figures are above.

Dapr is an open-source runtime that provides APIs for durable workflows and distributed application services. Its workflows handle long-running stateful processes with retries, timers, human approvals, and sagas. Dapr also supports AI agents using checkpointed plans to recover after failures. Service invocation offers HTTP or gRPC communication with discovery, tracing, and error handling; additional APIs cover pub/sub, state, actors, jobs, secrets, configuration, bindings, distributed locks, and cryptography. Dapr runs as a sidecar process or container, keeping its runtime code out of application code. It can run on Kubernetes or self-hosted on Windows, Linux, or macOS machines, including physical and virtual machines across cloud and edge environments. Security includes mTLS encryption in transit, access policies, and automatic certificate rotation. Stable SDKs are available for.NET, Python, Java, Go, PHP, and JavaScript. Dapr is free and open source. Separate paid options include Dedicated Cloud starting at $1,199 a month and BYOC starting at $1,599 a month; both list a first 14 days free.
