Webhook Relay receives, transforms and delivers webhooks to any destination — a public URL, a private server, or your localhost. With durable retries your events survive outages, deploys and flaky endpoints, so nothing slips through.

Cozystack logo Cozystack

With Cozystack, you can transform your bunch of servers into an intelligent system with a simple REST API for spawning Kubernetes clusters, Database-as-a-Service, virtual machines, load balancers, HTTP caching services, and other services with ease.

What is Webhook Relay?

Webhook Relay is an enterprise-ready webhook delivery platform — SOC 2 Type II certified, encrypted at rest and in transit, with SSO, audit logs, role-based access and an optional self-hosted deployment (see Enterprise-ready below).

It is a secure tunneling solution that provides:

  • Webhook forwarding - secure, unidirectional by default with optional request/response transformation.
  • Bidirectional tunnels - fast tunnels for direct access to any HTTP service. This is ideal for accessing internal APIs and demoing websites.

Use Cases

Popular use cases:

  • Receive Stripe, Shopify, GitHub and other webhooks on your local machine while developing your application.
  • Allow remote clients to connect to your backend, for example AWS EC2 instances communicating with your MacBook Pro.
  • Forward a single webhook to multiple destinations, for example Slack and GCP PubSub.
  • Transform webhooks, for example Docker push webhook into a Slack message.
  • Demo your website to clients or customers.
  • Access IoT devices and sensors remotely.

Enterprise-ready

Webhook Relay is built for teams that can't afford to miss an event:

  • SOC 2 Type II certified — read the security & tech overview.
  • Encryption everywhere — AES-256 at rest, TLS in transit, plus optional ephemeral buckets that store nothing.
  • SSO & SAML with Okta, Azure AD and more, role-based access and audit logs.
  • 99.99% uptime SLA on high-availability infrastructure, with durable retries for up to 30 days.
  • Durable Delivery - never miss a webhook, retries over hours, days and weeks.

Cozystack features and specs

  • Free and Open Source
    Cozystack is a fully open-source platform (under Apache 2.0 license) built on top of proven open-source technologies like Kubernetes, Talos Linux, and FluxCD, allowing users to inspect, modify, and contribute to the codebase without vendor lock-in.
  • All-in-One PaaS/IaaS Platform
    Cozystack provides a comprehensive platform that combines PaaS and IaaS capabilities, offering managed Kubernetes clusters, databases (PostgreSQL, MySQL, Redis, etc.), virtual machines, load balancers, and monitoring out of the box, reducing the need for multiple separate tools.
  • Built on Battle-Tested Technologies
    The platform leverages well-established cloud-native technologies such as Kubernetes, KubeVirt for virtualization, Kamaji for managed Kubernetes, and Cilium for networking, providing a solid and reliable foundation rather than reinventing the wheel.
  • Simplified Bare-Metal Deployment
    Cozystack is designed to be installed directly on bare-metal servers using Talos Linux, making it relatively straightforward to set up your own cloud infrastructure without needing pre-existing cloud providers or complex manual configurations.
  • GitOps-Driven and Declarative Management
    Using FluxCD and Helm charts under the hood, Cozystack follows GitOps principles, enabling declarative infrastructure management, reproducible deployments, and easy customization of platform components through a standardized workflow.

Possible disadvantages of Cozystack

  • Steep Learning Curve
    Cozystack requires solid knowledge of Kubernetes, Talos Linux, networking, and various cloud-native technologies. Users unfamiliar with these ecosystems may find the initial setup and ongoing management challenging.
  • Relatively Young and Small Community
    Compared to established platforms like OpenStack or major managed Kubernetes services, Cozystack has a smaller user community, which means fewer community-contributed resources, tutorials, third-party integrations, and slower issue resolution from peers.
  • Limited Enterprise Support and Ecosystem
    As a relatively new open-source project, Cozystack lacks the extensive enterprise support contracts, professional services, and partner ecosystems that more mature platforms offer, which may concern organizations requiring SLA-backed support.
  • Hardware and Infrastructure Requirements
    Cozystack is designed for bare-metal deployments and requires a minimum cluster of nodes with specific hardware capabilities (e.g., for KubeVirt virtualization), which may not be accessible or cost-effective for smaller teams or those without dedicated infrastructure.
  • Limited Documentation and Maturity
    Being a newer project, the documentation can be sparse or incomplete in certain areas, and some features may still be evolving, potentially leading to breaking changes or gaps in functionality compared to more mature alternatives.

  • RudderStack: How Pachyderm Pipelines Help Parse Customer Event Data
    Apart from customer events, Pachyderm collects data from Pachyderm Hub, its SaaS platform. This data mainly includes the customers' workspace usage details and other metrics related to the platform usage and performance. Pachyderm clusters (which host both their open-source and enterprise offerings) also generate a large chunk of the workspace usage data.

  • Best self hosted micro blog?
    What's good about Hugo is really fast build times, previously I used both hexo.io and https://vuepress.vuejs.org/ but while vuepress is nice to start with it's nearly impossible to finish the website due to lack of features. Hexo is also nice but their templating language is not always intuitive (my hexo based website: https://webhookrelay.com/). Source: almost 5 years ago
