The short version

  • Only Bruno 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.; Bruno native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • They diverge on capability: Basis Theory covers Tokenisation API, Bruno covers API Testing.
  • Prices and features above were last checked on 31 August 2026.

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.

Bruno

  • Native Git integration, the feature that distinguishes it from cloud API clients, is Pro only at $6 per user per month
  • OpenAPI syncs are capped at 5 a month on the free tier
  • SSO, SCIM and user management require Ultimate at $11 per user per month
  • Private workspaces are a paid feature
  • Advertised prices are annual rates

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.

Bruno: What is included in Bruno's free tier?

The Open Source plan includes the core API client, limited Git integration, and up to 2 workspaces at no cost. A 14-day free trial of the Ultimate plan is also available without requiring a credit card.

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.

Bruno: What is the difference between Bruno Pro and Ultimate plans?

Pro ($6/month) includes native Git integration and unlimited workspaces. Ultimate ($11/month) adds SSO/SCIM support, audit logs, 24-hour support (vs. 48-hour), and an account manager. Ultimate supports unlimited OpenAPI syncs while Pro is limited to 5 per month.

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.

Bruno: How much does Bruno Pro save compared to other API tools?

The vendor claims Ultimate saves teams more than 70% versus Postman, though this comparison is promotional rather than a specific cost metric.

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.
