The short version

  • Each has a real cost: OpenEBS there is no vendor on the other end of an incident unless you separately contract DataCore, so an outage at three in the morning is resolved by your own team and a public Slack channel.; REST Client VSCode limited to Visual Studio Code; not available as a standalone application
  • They diverge on capability: OpenEBS covers Replicated engine, REST Client VSCode covers REST Client.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

OpenEBS

  • There is no vendor on the other end of an incident unless you separately contract DataCore, so an outage at three in the morning is resolved by your own team and a public Slack channel.
  • The project has several storage engines with different maturity and different operational characteristics, and choosing the wrong one for your workload produces poor results that look like a product failure.
  • Documentation and upgrade guidance assume real Kubernetes storage knowledge, so teams without that expertise underestimate the operational load they are taking on.
  • Project governance shifted after DataCore acquired MayaData in 2021, which means the direction of a supposedly neutral project is influenced by one commercial sponsor.
  • Disaster recovery, cross-cluster replication and policy-driven data services are thinner than in the commercial alternatives, so organisations with those requirements end up building them or buying a product anyway.

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

Can I use OpenEBS for free?
Both have a free tier, so you can try either at no cost before committing.
What is OpenEBS best used for?
OpenEBS is most often used for running cassandra or kafka on kubernetes where the application already replicates and node-local volumes are sufficient, a platform team that needs persistent volumes on bare metal kubernetes without a per node subscription, an edge or lab deployment where a commercial storage licence cannot be justified, replacing hostpath volumes with something that has snapshots and a container storage interface driver. Of those, running cassandra or kafka on kubernetes where the application already replicates and node-local volumes are sufficient and a platform team that needs persistent volumes on bare metal kubernetes without a per node subscription are not what REST Client VSCode is typically brought in for.

Answered from the vendors’ own pages

OpenEBS: Who supports it in production?

The project is community supported. Commercial support is available from DataCore, which acquired the original sponsor MayaData in 2021. Establish that relationship before production, not during an incident.

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
OpenEBS: Which engine should we use?

If your application replicates its own data, use a Local engine and avoid replicating twice. If it does not, such as with PostgreSQL, use the Replicated engine.

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
OpenEBS: Does it cost anything?

No licence fee. The cost is operational, and a support contract if you want someone accountable.

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
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.
