The short version

  • Only Rust has a free tier, so it costs nothing to try first.
  • Each has a real cost: Rust compile times significantly longer than languages like Go or C; WorkOS authKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month
  • Prices and features above were last checked on 30 August 2026.

Only in Rust

  • Memory safety
  • Zero-cost abstractions
  • Ownership system
  • Pattern matching
  • Type inference
  • Cargo package manager
  • Cross compilation
  • Fearless concurrency

Only in WorkOS

  • Platforms with multiple identity provider requirementsnot Rust

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Rust

  • Compile times significantly longer than languages like Go or C
  • Smaller ecosystem of libraries and frameworks compared to Python or JavaScript
  • Community still smaller than mainstream languages, reducing available third-party resources

WorkOS

  • AuthKit free tier limited to 1 million monthly active users; additional millions cost $2,500/month
  • Per-connection pricing for SSO and Directory Sync ($125–$50 each) scales poorly for enterprises with many identity providers
  • Audit logs require separate subscription at $125/month per SIEM connection or $99/month per 1 million events
  • Radar fraud protection billed separately at $100/month per 50,000 additional checks beyond 1,000 free checks
  • Custom domain feature requires $99/month subscription
  • Requires annual commitment for SLA and support guarantees; pay-as-you-go tier lacks uptime guarantee
