WorkOS

The platform offers a collection of APIs and SDKs that let developers integrate enterprise‑grade authentication into their applications. It supports Single Sign‑On with any SAML or OIDC provider, directory synchronization, audit logging, and user lifecycle management, all accessed through a unified RESTful interface and webhook events. A customizable authentication UI, passwordless login, and multi‑factor authentication are also available.

Developers can manage users, organizations, and policies, and can enable social sign‑in through providers such as Microsoft and Google. The service includes role‑based access control, real‑time bot and fraud protection, and an admin portal designed for corporate IT teams to self‑serve onboarding.

The offering is packaged for multiple programming environments, with SDKs for Node.js, Ruby, Python, Go, Java, .NET, PHP and cURL, and it normalizes responses from more than twenty enterprise identity services. It is positioned as a stable, developer‑first solution for adding secure login and compliance features to SaaS products.
