OpenFaaS Pro

OpenFaaS Pro is a commercially licensed distribution of OpenFaaS with additional features, configurations and commercial support from the founders.

Do we need the Community Edition or Pro?

OpenFaaS Community Edition (CE) is meant for open-source developers and basic exploration, OpenFaaS Pro is meant for production.

Core platform

Efficiency and redundancy:

Scaling that works for various types of functions

Scaling that works for various types of functions

The OpenFaaS Pro autoscaler emits detailed usage information, meaning functions can scale not just on requests per second, but inflight requests and CPU utilisation.

Usability and operations:

The OpenFaaS dashboard

The OpenFaaS dashboard integrates with CPU & RAM usage metrics, and container logs to give you insights on your functions in one place. You can also add metadata from your source control management tool like a SHA, owner, project or URL to the source code.

Events and triggers

Event-driven programming and triggers:

Workload tuning

To avoid errors when scaling up or down, you may need to tune your function's configuration to suit how it works. Pro users get access to fine-tune health checks, set custom Kubernetes service accounts and termination grace periods for shutting down functions.

  • Custom HTTP health checks for functions - including path, period seconds and initial delay
  • Custom Kubernetes service accounts for functions to access the Kubernetes API
  • Custom runtime profiles for security & isolation using gVisor, kata containers etc.
  • Custom TerminationGracePeriod for draining work for long running functions
  • Custom support for probing Istio endpoints during scale from zero

Enterprise security

  • Single Sign-On using OpenID Connect (OIDC) means each user authenticates with their own identity, instead of sharing one set of credentials, which is insecure. Use your existing OIDC-compatible Identity Provider (IdP).

Platform building features

Build functions at scale - for services providers and large teams:

On our roadmap

Recently released:

  • Scaling upon inflight requests for long running & memory/CPU bound functions (released Jan 2022)
  • A new Pro UI dashboard for managing and monitoring OpenFaaS functions across namespaces (released March 2022)
  • CPU and RAM usage metrics within the OpenFaaS API, CLI and Pro UI dashboard (released Feb 2022)
  • AWS SQS event-connector (released January 2022)
  • Concurrency limiting for functions - i.e. one request per container
  • Redesigned async system with NATS JetStream which replaces NATS Streaming (available in pilot)
    • NATS Streaming is available for CE and will be deprecated in June 2023.
    • Dedicated Helm chart for installing additional queue-workers with JetStream
    • Structured logging / JSON for OpenFaaS Pro customers in the queue-worker


  • Enhanced RBAC for functions and the OpenFaaS REST API
  • AMQP event trigger for RabbitMQ and Azure Service Bus
  • Enhanced multi-tenant isolation for large organisations and service providers

Do we need the Community Edition or Pro?

OpenFaaS Community Edition (CE) is meant for open-source developers and basic exploration, OpenFaaS Pro is meant for production.

OpenFaaS Pro is a distribution of OpenFaaS with additional features and configurations that we believe customers need to operate a product or service in production.

As we tune OpenFaaS Pro for our existing customers, we improve it for everyone else at the same time - writing articles, tuning configuration and adding key features.

We see it as the start of a two-way relationship and an opportunity to collaborate directly with our team.

OpenFaaS Enterprise comes with support for the Certified Open Source Components and OpenFaaS Pro, with support via email within a Service Level Agreement (SLA). Along with email support, each team gets their own dedicated Slack channel for questions, collaboration and assistance.

OpenFaaS Pro operates on a self-service model with support for OpenFaaS Pro features only via email.

Both tiers come with access to the Customer Community, for feedback & collaboration with the OpenFaaS developers and other customers.

No support is offered to commercial users of OpenFaaS CE, which is primarily meant for exploration and open source developers.

Getting started

OpenFaaS Pro is developed primarily for team deploying to Kubernetes, however most of the features are also compatible with faasd. Learn about faasd and OpenFaaS Pro here: The Event-Driven Edge with OpenFaaS
