Take a longer-term view
Run the battle-tested version of OpenFaaS in production, with support and regular updates.
Reduced time to market
With dozens of language templates, access to private NPM, maven, gradle, Nuget and Go code repositories from faas-cli, you'll be able to ship code in a short period of time with the languages you already use.
The reliability your customers need
OpenFaaS Standard with JetStream brings at least once semantics and a highly scalable queue with built in metrics showing the amount of work left to process. Failed requests can be retried, and additional named queues can be added as you grow.
Highly scalable
Kubernetes uses a generic autoscaler that was never built to scale functions. OpenFaaS Pro scaling can be fine-tuned to any workload. You can pick from Requests Per Second (RPS), CPU usage or Capacity (the amount of connections). Capacity mode scales slow running functions and ETL workloads which neither the Community Edition or Kubernetes can.
Just as important as scaling up, scaling down to zero keeps costs low whilst retaining the benefits.
Compliance matters
OpenFaaS Standard supports Istio and Linkerd for mutual TLS encryption between functions. OpenFaaS for Enterprises includes Single-Sign On, auditing and Role Based Access Control (RBAC).
Pro's integration with ArgoCD, FluxCD through Custom Resources Definitions (CRDs) means that you can audit deployments through git, and make SOC2 compliance easier to achieve.
Find problems before they find you
OpenFaaS Pro comes with Grafana dashboards showing you everything that could go wrong with a function, from errors due to timeouts, increasing latency, spikes in CPU and memory leaks. You'll be able to fix these issues before your customers even see them.
Collaborate and contribute
In the Customer Community, you'll get early access to new features and be able to leave feedback and suggestions for things that would make OpenFaaS better for your team. Rest assured that with OpenFaaS For Enterprises, you get an SLA and direct access to our engineering team via Slack.

CTO, Kubiya.ai
How did you evaluate and decide on OpenFaaS?
“Exploring serverless orchestration on Kubernetes at Kubiya, we encountered powerful platforms like Knative, yet found them overly complex to manage. OpenFaaS struck the perfect balance. It combines dynamic elasticity, intuitive function packaging, a robust API and comprehensive metrics. With secure namespace isolation for managing multi-tenant environments, OpenFaaS has proven to be a perfect fit for our needs.”

Is there a specific example you can share of how we helped?
"The biggest difference I noticed in the early days of adoption is how helpful the OpenFaaS team was when I was going through the onboarding process. I had a lot of questions about very specific needs. All of these questions were easily answered and examples were provided. If you are trying to solve a unique problem, Alex's perspective has always been valuable."
