Auth0 vs Klaim (formerly Ceeya)

Auth0 is a customer identity and access management platform from Okta. It handles authentication and authorization for web, mobile, and API applications so development teams can add login, SSO, and access controls without building identity infrastructure from scratch.

The platform covers B2C consumer apps, B2B SaaS products, and internal tools. Developers integrate via SDKs and quickstarts for stacks like React, Next.js, iOS, Android, Java, .NET, and Python. Auth0 also ships dedicated tooling for securing AI agents, including user authentication before agent access, Token Vault for scoped API credentials, and fine-grained authorization for RAG pipelines.

Auth0 reports blocking 3 billion-plus attacks monthly across Okta and Auth0 platforms, 99.99% uptime, and 10 billion-plus authentications per month. Customers listed on the site include Siemens, Signify, Zapier, Wyndham Hotels, and the City of Los Angeles.

Klaim is a billing platform built for AI startups that sell usage credits instead of flat subscriptions. You publish pricing pages, collect payments through your own Stripe account, and track how customers spend credits across your product. The product is aimed at teams that want to experiment with pricing without filing an engineering ticket every time a plan changes.

The platform covers the full loop: hosted pricing pages, credit wallets per user, A/B tests on plan variants, and dashboards for conversion and revenue per visitor. Klaim also includes CAIRO, a beta assistant focused on pricing strategy, plus a public directory that compares AI model token costs across hundreds of models.

Founders, growth leads, and product managers at early-stage AI companies are the core audience. If you ship token-based features and need a way to charge for them without building billing infrastructure from scratch, Klaim is built for that workflow.
