No authoritative market share figures for the vendor were located in the public sources used for this report. Third-party estimators exist but should be evaluated for methodology before use in decision-making.
| Starting Price | Reported free tier includes a modest MAU allowance; a growth tier price is listed on some third-party pages | Modular pricing: some user management features are available without per-user charges; SSO & Directory Sync are commonly billed on a per-connection basis | Open-source software with no license fee; self-hosting entails infrastructure and operational costs |
| Primary fit | B2B SaaS needing organization model, RBAC, SSO/SCIM with hosted UI and SDKs | Organizations that want to bolt enterprise SSO/SCIM onto an existing identity stack via modular add-ons | Organizations with strong DevOps/security teams that require full control and self-hosting |
| Key strengths | B2B-oriented primitives and developer-focused integrations/SDKs | Modular enterprise features and a clear per-connection pricing model | Control, extensibility, avoidance of vendor lock-in |
| Key weaknesses | Hosted UI customization limits for some use cases; vendor is relatively younger than large incumbents | Per-connection costs can become material for some sales models with many SSO connections | Significant implementation and maintenance burden; longer time-to-value |

PropelAuth and WorkOS take different approaches: WorkOS provides modular enterprise capabilities that can be added to an existing identity stack, with per-connection billing for SSO and Directory Sync, while PropelAuth provides an integrated B2B identity stack with hosted flows and a tenant/organization model. Buyers should validate definitions such as "unlimited SSO" in contract language to confirm any practical limits or fair-use policies.
Compared with Auth0, PropelAuth markets the convenience of prebuilt B2B flows and development ergonomics; Auth0 and other larger vendors may offer broader integration catalogs, procurement maturity, and feature breadth. Versus Keycloak, PropelAuth is a hosted managed service providing faster time-to-value at the cost of vendor-managed infrastructure.
