The short version

  • Each has a real cost: containerd not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah; REST Client VSCode limited to Visual Studio Code; not available as a standalone application
  • They diverge on capability: containerd covers Full container lifecycle, REST Client VSCode covers REST Client.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

containerd

  • Not a developer-facing tool: there is no build command and the CLI is deliberately minimal, so it needs companions like nerdctl or Buildah
  • Debugging is lower-level than Docker, and error messages assume knowledge of the runtime internals
  • Documentation is aimed at platform engineers, so newcomers usually find Docker or Podman material more useful
  • No image building at all — that is out of scope by design

REST Client VSCode

  • Limited to Visual Studio Code; not available as a standalone application
  • No support for WebSocket, gRPC, or other advanced protocols
  • No cloud sync or team server features; requires Git-based workflow

Answered from the vendors’ own pages

containerd: Is containerd free?

Yes. It is an open-source CNCF graduated project with no licence fee.

REST Client VSCode: How much does REST Client VSCode cost?

REST Client VSCode is completely free and open source. It is available on the Visual Studio Code Marketplace with no subscription or licensing fees.

Source
containerd: Do I need containerd if I use Docker?

You already have it. Docker uses containerd underneath to run containers; it is not an alternative you install separately.

REST Client VSCode: What authentication methods does REST Client support?

REST Client supports Basic Auth, Digest Auth, SSL certificates, Azure AD, and AWS Signature v4 authentication for API requests.

Source
containerd: Why did Kubernetes drop Docker for containerd?

Kubernetes talks to runtimes through the Container Runtime Interface. Docker did not speak CRI natively and needed a shim, so Kubernetes removed the shim and talks to containerd directly, which Docker was already using anyway.

REST Client VSCode: Can I save and manage multiple requests?

Yes. REST Client supports multiple requests per file using ### delimiters, request history with auto-save, environment variables for different configurations, and code snippet generation for multiple programming languages.

Source
containerd: Can containerd build images?

No. Image building is deliberately out of scope. Tools such as Buildah, BuildKit or Docker handle that.

REST Client VSCode: How do teams collaborate with REST Client?

REST Client requests are stored as text files that can be version-controlled in Git repositories. Teams collaborate by sharing requests through Git, making the API specs part of the codebase.

Source
REST Client VSCode: What protocols does REST Client support?

REST Client primarily supports HTTP/HTTPS and GraphQL. It does not support WebSocket, gRPC, or other advanced protocols available in desktop clients like Insomnia.

Source
REST Client VSCode: Is there cloud sync for REST Client requests?

No. REST Client has no built-in cloud sync or team server features. All collaboration and sharing relies on Git repository management.
