OpenFaaS is a serverless functions platform that lets developers deploy event-driven functions and microservices packaged as OCI/Docker containers to Kubernetes or a single VM (via faasd). It provides a UI, CLI, REST API, autoscaling, and event triggers (Kafka, SQS, cron, etc.), with a commercial Standard/Enterprise tier and a free Community Edition limited to personal use.

Use cases

• deploy serverless functions to kubernetes
• run event-driven functions triggered by kafka or sqs
• scale functions to zero to save costs
• run a lightweight faas platform on a single vm without kubernetes
• build etl and data pipelines with parallel function execution
• offer customers a sandbox to run their own code snippets
• offload background tasks with async queuing and retries

When to choose

• you want portable, language-agnostic functions packaged as Docker/OCI images on Kubernetes or a single VM
• you need event-driven triggers from Kafka, RabbitMQ, AWS SQS/SNS, GCP Pub/Sub, cron, or MQTT
• you want a self-hosted alternative to AWS Lambda with a UI, CLI, and REST API
• you need commercial support and production features like scale-to-zero, SSO, and RBAC

When to avoid

• you need a fully open-source license for commercial production use - Community Edition has a 60-day commercial limit and paid tiers are required
• you want a managed serverless service without operating your own infrastructure
• your workload is simple enough that plain containers or a scheduler would suffice
• you need more than 15 functions or multiple namespaces on the free tier
