Basis Theory

Basis Theory is a cloud payment-data platform for businesses that need to keep card data out of their systems while working with multiple payment providers. It is a stronger fit for established payment teams than small operators: the Standard plan starts at $995 per month, before additional-token charges.

Overview

Basis Theory tokenizes card data as it is collected, keeping raw primary account numbers from touching customer systems. It centralizes sensitive payment data, governs access, and routes tokens to payment providers and other services. The vendor hosts the vault, and a detokenization API is available.

The API is designed to connect with existing PSPs, including Stripe, Adyen, Worldpay, Chase, Braintree, Nuvei, Amazon Pay, and ACI. That flexibility matters to teams managing more than one provider, but the Standard plan’s US-only environment is a poor fit for deployments that require another environment.

Key features

Proxy supports routing, Reactors provide server-side logic, Elements handle sensitive-data collection, and Token Intents validate data before tokenization. Together, these tools cover more of the payment-data workflow than a vault alone. Vault capabilities also include Account Updater, BIN Details, Network Tokens, and 3DS, with credit cards, bank accounts, Apple Pay, and Google Pay among the supported payment methods.

Documented SDKs span .NET, Java, Go, NodeJS, Python, Terraform, React, JavaScript, iOS, Android, and React Native. That range gives teams options across backend, web, and mobile projects. Basis Theory states that it is PCI Level 1 compliant, SOC 2 Type II and ISO 27001 certified, and HIPAA compliant; it also says data is encrypted at rest and in transit with tenant-specific keys, and communications use TLS 1.2 or later.

Pricing

Standard platform: $995 a month, billed monthly, with the platform fee charged at the beginning of the month. It includes 20,000 tokens, then charges $0.05 per additional token. The plan also sets a 1MB payload limit, retains logs for 24 hours, and is limited to a US environment. Tokens added and deleted within the same calendar month still count toward that month’s total, so frequent token turnover can increase charges. This plan suits teams whose expected volume, payloads, and deployment region fit those boundaries.

Enterprise: custom pricing. It adds options for additional PII and PHI compliance, unlimited monthly interactions per token, custom log access and payload size, uptime guarantees, enterprise support, and SSO/SAML. It is the more appropriate tier for organizations that need those controls or service terms; the tradeoff is a sales-led purchase rather than a published price.

Platforms

Basis Theory supports Android, iOS, web, and API access. Its cloud deployment and vendor-hosted vault avoid a self-hosting requirement, while the Standard plan’s US-only environment remains a significant regional restriction.

Who it's for

The company identifies creator economy, digital health, e-commerce, fintech, gaming, subscription platforms, and vertical SaaS as use cases. The common case is a business that handles sensitive payment data and wants to route tokens across existing providers. Implementation, bug, and issue support is available by email; private Slack or Microsoft Teams channels are offered through Sales.

Pros and cons

• Broad payment workflow: collection, validation, routing, server-side logic, and vault features sit in one platform.
• Provider and SDK coverage: the API targets existing PSPs, and documented SDKs cover major backend, web, and mobile options.
• Security controls: the company states multiple compliance credentials and encryption protections, relevant to teams handling sensitive payment data.
• High entry cost and metered usage: Standard starts at $995 per month, includes 20,000 tokens, and charges for additional tokens; deleted tokens still count for the month.
• Limited Standard environment and logs: US-only deployment and 24-hour log retention may not suit teams with other regional or operational needs.

Alternatives

Payment Tokenization Software is the category directory for comparing options. Choose American Express Token Service if a free plan and no stated deployment or use fees matter more; availability varies by market. Hyperswitch Card Vault is worth considering for teams seeking a free, self-hosted community edition with 90+ payment integrations, provided they are prepared to manage compliance themselves. DeloPay may suit teams that prefer transaction-based pricing and a free trial, though its Power plan charges 2.25% per transaction at the stated volume tier.

Cashfree Token Vault, FIS Data Integrity Manager, Very Good Security, Worldpay eProtect, and Mastercard Decision Intelligence are also alternatives to compare.

Verdict

Basis Theory is best for payment teams that need tokenization, access governance, and routing across providers, and can justify a $995 monthly starting commitment. Its broad toolset and integrations are compelling; look elsewhere if you need a non-US Standard environment, lower fixed costs, or a token model that does not count same-month deletions.
