The API development platform that defined the category, used by 30M+ developers at 500K+ companies. Positioned as the shared workspace for API design, testing, monitoring, and documentation. Distinctive for its collection-based workflow that made API testing collaborative before Insomnia and Bruno existed. Priced $14-$29/user/mo across Free/Basic/Professional plus custom Enterprise. Also offers Postman AI Agent Builder (2024 launch) for AI-powered API workflows. Founded 2014 in Bangalore, $5.6B valuation (2021 Series D). Public API network hosts 200K+ published APIs.
Enterprise-ready authentication + user management, positioned as the alternative to building SSO/SCIM/directory sync from scratch. Distinctive per-connection pricing model — $125/mo per SSO connection (vs Clerk's bundled 1 free SSO on Pro). AuthKit free for first 1M users. Popular with B2B SaaS that need to close enterprise deals requiring SAML, SCIM, and audit logs — the "unlock enterprise revenue" tool.

What each is best for
Postman is worth it if… engineering teams (3-500 developers) that build, test, and consume APIs — particularly if you have more than 5 developers hitting the same API surface. Free covers solo learning + hobby projects (3 collaborators); Basic adds unlimited history and version control; Professional adds unlimited collaborators, SSO add-on, and 100K API calls; Enterprise adds SCIM, audit logs, and unlimited scale.
WorkOS is worth it if… B2B SaaS companies (Series A-Series D) that need to add enterprise features (SSO, SCIM, audit logs, admin portal) to their product — particularly to close enterprise deals that require SAML/OIDC. Startup tier covers small SaaS; Enterprise for high-volume with custom pricing.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
