Auth0 vs Theneo

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.

Theneo is a developer portal and API documentation web app where your team publishes references, guides, changelogs, and private customer hubs from one workspace. Upload OpenAPI, Postman, or GraphQL specs, or connect GitHub, GitLab, or Bitbucket, and Theneo generates interactive reference pages with code samples and a built-in Try-it console. More than 15,000 teams use it for docs that stay tied to the API instead of drifting in a separate writing tool.

Most API doc stacks split engineers and writers across export cycles: specs leave the repo, copy lands in a docs CMS, and nobody updates both when the API changes. Theneo keeps engineers, writers, PMs, and coding agents in the same documents with live cursors, inline comments, and version history. It also ships MCP server support, llms.txt, and Ask AI so customer agents can query your docs, not just humans reading static pages.

B2B API companies use Theneo when one public docs site is not enough. You can spin up authenticated portals per customer, restrict which APIs each account sees, and apply custom branding per segment. Enterprise teams pick it for SOC 2 Type II coverage, SAML SSO, optional self-hosting on AWS, Azure, or Google Cloud, and breaking-change alerts tied to CI deploys.
