Paraglider is an open-source project under the Linux Foundation. It originated from research at the UC Berkeley NetSys Lab and is being advanced by a cross-industry working group involving members from Microsoft, Google, IBM, and UC Berkeley. Its goal is to abstract complex cloud networking capabilities—such as virtual networking, access control, load balancing, and cross-cloud connectivity—into higher-level descriptions of connectivity, security, and network functions, creating a unified cross-cloud control plane.
Functionally, Paraglider lets users describe connectivity requirements around VMs, containers, PaaS resources, and similar infrastructure, while its controller translates those requirements into cloud-provider configurations through cloud plugins. It provides models such as namespace, resource, permit list rule, and tag, enabling semantic names and groupings instead of direct IP/CIDR operations. Current plugins cover Azure, GCP, and IBM. VM support is relatively well defined, while Kubernetes clusters and managed services are mostly still in an Initial state. Multi-cloud connectivity already has partial support across Azure/GCP/IBM combinations.
The project provides the glide client and glided server CLI, as well as a REST API covering operations such as resource creation/attachment, rule CRUD, tag resolution, and service startup. Development is primarily in Go, with build dependencies including Git, Go, golangci-lint, protoc, and make. It supports macOS, Linux, Windows WSL, and Dev Container environments. The documentation is fairly complete, including API references, a Quickstart, examples, feature status, build instructions, and contribution guides, making it accessible for developers who want to get started or contribute.
No commercial pricing is mentioned in the main documentation, and the project itself is open source. Users can build, install, and run the controller and related services themselves, so it has self-hosting characteristics. However, integration and multi-cloud testing will make real calls to cloud-provider resources and may require an Azure subscription, GCP billing account, IBM API Key, and similar credentials. Users need to manage the associated costs and permission risks themselves.
Its strengths are a clear focus on multi-cloud network abstraction, open APIs and a plugin mechanism, and participation from major organizations. The downside is that it is still in active development, with uneven maturity across features. For example, resource attachment is currently supported only on Azure, in progress for GCP, and not supported on IBM. It also lacks clear information on SLA, stable releases, or commercial support. Paraglider is better suited to platform engineering teams, cloud networking teams, researchers, and users willing to participate in an early-stage open-source project. It is less suitable for teams that need strong production guarantees immediately.
The main documentation does not provide information about access from mainland China, mirrors, payment, or compliance, so its accessibility can only be marked as unknown. If a team depends on GitHub, Discord, and overseas Azure/GCP/IBM cloud resources, users in China may need to evaluate network connectivity, account payment, and cloud resource availability. Comparable alternatives include Terraform, Pulumi, Crossplane, OpenTofu, or cloud-native network IaC solutions from individual providers.
