The short version

  • Only REST Client VSCode has a free tier, so it costs nothing to try first.
  • Each has a real cost: Basis Theory the Starter plan is 995 US dollars a month before any volume, which is a real floor for an early stage company and puts the product out of reach of teams tokenising a few thousand records.; REST Client VSCode limited to Visual Studio Code; not available as a standalone application
  • They diverge on capability: Basis Theory covers Tokenisation API, REST Client VSCode covers REST Client.

Where each one falls short

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

Basis Theory

  • The Starter plan is 995 US dollars a month before any volume, which is a real floor for an early stage company and puts the product out of reach of teams tokenising a few thousand records.
  • Starter is limited to the US region, so a company with European data residency requirements is pushed into a quoted Scale or Enterprise agreement immediately.
  • Log retention on Starter is 24 hours, which is well below what most security teams expect for a system holding cardholder data and forces an upgrade for reasons unrelated to volume.
  • Migrating away means moving card data out of the vault, which requires processor and assessor involvement and is slow, so the portability argument that attracts buyers cuts against them at exit.
  • An attestation of compliance covers the vendor environment, not your assessment; your assessor still decides what is in scope, and buyers occasionally discover their integration pattern pulled systems back into scope 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

Answered from the vendors’ own pages

Basis Theory: Does this make us PCI compliant?

It removes cardholder data from your systems and gives you an AOC plus documented responses for most of a SAQ D. Your assessor still determines your scope, and a careless integration can pull systems back in.

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
Basis Theory: What does it cost to start?

995 US dollars a month on Starter, including 20,000 tokens, a production PCI Level 1 environment and US hosting. Higher tiers are quoted.

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
Basis Theory: Can we switch payment processors without re-collecting cards?

Yes, that is the main non-compliance reason to buy it. You hold the tokens and detokenise into whichever processor you route to.

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
Basis Theory: Is data stored outside the United States?

Not on Starter, which is US only. Other regions require a Scale or Enterprise agreement.

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.
