OpenFaaS Edge

Deploy event-driven functions to customer sites — on VMs or bare-metal, without Kubernetes.

Built for redistribution

OpenFaaS Edge is designed for OEM and whitelabel solution providers who need to ship event-driven automation as part of their product. Package your functions and deploy them to your customers' environments — on-premises, air-gapped, or at the edge.

Build

Write functions using
standard templates & tooling

Package

Container images stored
in your private registry

Ship

Deploy to customer sites
on-prem, airgapped, or at the edge

Unlike OpenFaaS Standard or Enterprise, Edge runs without Kubernetes. It deploys to a single VM or bare-metal host using containerd, keeping operational overhead low and making it practical to redistribute to dozens or hundreds of customer sites.

Industry use cases

Edge is ideal for industries that deploy automation to customer sites or remote locations:

Rail Freight Shipping Telecoms Manufacturing Logistics Industrial Automation Edge Monitoring ETL Data Pre-Processing

If your product includes scheduled jobs, webhook integrations, data pipelines, or event-driven processing that needs to run at a customer site rather than in your cloud, Edge gives you a ready-made runtime with a commercial redistribution license.

Capabilities

Deployment

  • Single Linux host — VM, bare-metal, or cloud instance
  • Same templates and tooling as OpenFaaS on Kubernetes
  • Airgap support with preloaded function images
  • TLS for securing the gateway

Scaling & queuing

  • Scale to zero when idle
  • Async queue with retries (JetStream)
  • Resource constraints for RAM/CPU per function

Security & isolation

  • gVisor sandboxing for container isolation
  • Read-only filesystem and non-root by default

Events & integrations

Stateful services

  • Run long-lived containers alongside functions via docker-compose
  • Attach Nvidia GPUs for AI/ML workloads (e.g. Ollama)
  • Preload functions and services for offline distribution

Optional add-ons

  • Function Builder API — build from source as non-root
  • OpenFaaS Dashboard
  • Additional event connectors beyond cron

Edge vs Standard

Edge and Standard solve different problems:

Edge Standard
Designed for Redistribution to customer sites Internal production use
Infrastructure Single VM or bare-metal Kubernetes cluster
Horizontal scaling No Yes, with fine-tuned autoscaling
High availability No Yes
Redistribution rights Yes, under commercial license No
Airgap support Yes Yes (annual license)
Functions included 25 (up to 500 via add-on) 500
Starting price $300/mo per installation $1,250/mo per cluster

Need functions for internal production use in your business? See OpenFaaS Standard instead.

Pricing

  • $300 USD/month is the starting price, per installation
  • Pricing scales based on deployment needs and function count
  • Paid annually by invoice — SWIFT (GBP) / ACH (USD)
