WorkOS offers a comprehensive solution for SCIM, supporting multiple directories, ease of integration, easy customer onboarding, scalability, configurable attribute mappings, compliance, transparent pricing, and standalone SCIM. Stytch provides a self-serve UI, SDKs, webhooks support, and a free tier for up to 5 connections, but lacks product maturity and the ability to pull updates. Frontegg offers a self-serve UI, audit logs, and webhooks, but is missing strong backend SDK support and clarity on pricing. Auth0's offering is new, with attribute mapping, session revocation, and webhooks, but lacks a self-serve UI, clear pricing, and supports only two directories. Descope provides inbound SCIM support, but has limited features and unclear pricing.
