Self-hosted tunnels, to connect anything.

inlets replaces opening firewall-ports, setting up VPNs, managing IP ranges, and keeping track of port-forwarding rules.

Self-hosted tunnels give you private and secure access to any service, wherever it's running.

inlets PRO is fast and easy to use

A better way to connect

Connect your applications securely without the hassle of VPNs, or the limitations of SaaS tunnels.

Connect anything, anywhere.

You self-host the tunnel server, and run the client alongside the private service. Once connected, you'll have your own private uplink between the two networks.

Tunnels are secured with TLS and work through almost any network conditions. So you do not need to raise a help desk ticket to open ports, configure routers, or send an engineer on site.

  • No sweat webhooks

    Not only can you share websites, blog posts drafts and APIs without publishing them on public cloud, but you can integrate directly with webhooks from Stripe, GitHub and Slack.

  • Extend the topology

    Use inlets tunnels to extend your network across edge, different clouds or Kubernetes clusters.

  • Hybrid cloud, without the hassle

    Connect legacy applications, GPUs or private test environments to the public cloud.

  • Host services on private Kubernetes clusters

    Whether your cluster is on a private cloud, or your laptop, get a TCP LoadBalancer just like on a managed cloud platform.

  • Scale to thousands of services

    inlets tunnels are light-weight and can scale massively to support thousands of tunnels. It's ideal for SaaS platforms and monitoring multiple environments. Can your VPN solution do that?

Expose multiple ports from a private network

In TCP mode, traffic received on the server is sent directly to the client.

Self-host any HTTP endpoint with a HTTPS certificate

Built-in Let's Encrypt makes it really easy to get users to access your private service.

Local Kubernetes, but with public IPs

The inlets-operator for Kubernetes makes it look and feel like you're using a cloud Kubernetes cluster.

"We're using inlets PRO to power our staging environments and give people preview build URLs. It's going great!"

"Riskfuel is using inlets to train machine learning models with millions of data points for clients over secure tunnels."

Addison van den Hoeven, DevOps Engineer @ Riskfuel

"We use inlets instead of Ngrok while developing with webhooks for our live chat product. This helps us develop integrations with Facebook, Twitter, WhatsApp and Google Business, without facing rate-limits."

"Thanks to the inlets-operator, I can now test cert-manager during development on my local Kubernetes cluster"

Maël Valais, Kubernetes engineer

"We offer managed Kubernetes to regulated institutions in Switzerland. Our customers' VPCs do not allow for any incoming connections, so we use inlets to connect their OpenShift clusters to our product."

“We build a suite of managed products for Kubernetes, and inlets means that we can test our code locally without rebuilding and redeploying it for every change”

Janos Matyas, Banzai Cloud

"Inlets PRO makes it easy for us to provide secure service and support of our Sense AI Platform deployed through cloud marketplaces, helping us deliver value sooner for our enterprise customers."

Frequently asked questions

Can I try before I buy?
