Auth0 vs Anything (formerly CreateApp AI)

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.

Anything is an AI app builder that turns plain-English prompts into working web and mobile apps with real code behind them. You describe what you want, and the platform handles design, backend, database setup, and deployment so you can ship without writing code yourself.

The builder covers the full stack: Postgres databases, authentication, Stripe payments, file storage, and integrations with frontier AI models like GPT-5, Claude, and Gemini. You can publish to the web with a custom domain or ship to the iOS and Android app stores from the same project.

It suits founders validating ideas, designers prototyping interfaces, and developers who want to skip boilerplate. The platform reports over 1.5 million builders on the service.
