Webhooks.cc is a free, open-source webhook inspection and testing platform built for developers. Create a unique endpoint URL, point any service at it, and watch requests arrive in real-time — headers, body, query parameters, IP, and timestamps, all formatted and searchable. Signed provider templates — Send realistic test webhooks from Stripe, GitHub, Shopify, and Twilio directly from the dashboard. Signature headers are generated automatically so you can verify your integration end-to-end without waiting for real events. CLI tunneling — Forward incoming webhooks to localhost with whk tunnel . No port forwarding, no ngrok — just a direct stream from your public endpoint to any local port and path you choose. TypeScript SDK — Programmatic access to every webhooks.cc feature. Create endpoints, send templates, and wait for matching requests with composable matchers — built for Vitest, Jest, and CI pipelines like GitHub Actions. MCP server — Connect your AI coding agent — Claude Code, Cursor, VS Code, or Codex — and let it create endpoints, send test webhooks, inspect payloads, and replay requests through natural language. Open source & simple pricing — The entire platform is open-source under AGPL-3.0, with the CLI and SDK available under MIT. The free tier includes 50 requests/day, unlimited endpoints, and full access to the CLI, SDK, and MCP server. Pro ($8/month) scales to 100,000 requests/month with 30-day retention.

Webhooks.cc features and specs

  • CLI Tool
    Allows for full control over the functionality of webhooks.cc, but also allows for tunneling to localhost, whatever port you desire and whatever path you desire.
  • SDK Tool
    Provides programmatic access to every webhooks.cc feature, with composable matchers for asserting on headers, body, and metadata in any test runner.
  • MCP Tool
    Connects your AI coding agent to webhooks.cc, letting it create endpoints, send test webhooks, inspect payloads, and replay requests through natural language.

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.

Generous free tier with full feature access and the cheap pro tier with very generous usage limits. And obviously, because we are developer first, and have a unique SDK and MCP offering.

What's the story behind your product?

Webhooks.cc's answer

Some time ago i was developing a now dead app, that app delivered webhooks, and i grew tired of webhook.site´s restrictive free tier, rotating endpoints and lack of developer tools, so i built my own, and eventually that internal dev tool grew to be webhooks.cc today.
