Positioning brief — for the SimpleWebAuthn team
Why the models put SimpleWebAuthn at #5 for passkey authentication api for consumer apps
- Mature open-source TypeScript libraries Gemini · Grok · Claude“Leading open-source TypeScript libraries (@simplewebauthn/browser + server)”
- Full control without vendor lock-in Gemini · Grok · Claude“absolute control and data ownership without vendor lock-in or recurring API costs”
- Zero runtime or per-MAU costs Gemini · Grok · Claude“zero per-MAU cost”
- Direct low-level WebAuthn implementation Grok · Claude“for direct, low-level WebAuthn/passkey implementation”
What the models credit Stytch (#1) with — and don’t credit SimpleWebAuthn
- Native mobile SDKs Claude“native mobile SDKs (iOS/Android) that wrap platform passkey APIs correctly”
- Sessions and fallback methods Claude · GPT · Grok“flexible sessions, fraud controls, and a generous 10,000-MAU free tier”
- Fraud detection and recovery flows GPT · Grok“excellent fraud detection/recovery flows”
What would move the rank — the models’ fix lines, unified
- Provide sessions and fallback flows Claude · Gemini · Grok“no user store, session management, fallback flows, or cross-platform mobile SDKs”
- Add backend auth infrastructure Gemini · Grok“Requires building your own backend auth infrastructure, session management, recovery, and UI”
- Reduce frontend and database development Gemini · Grok“Requires substantial development effort to build frontend UI components, database schemas, session management, and fallback flows from scratch.”

Best-in-class open-source libraries that provide absolute control and data ownership without vendor lock-in or recurring API costs. (Ranked first under the assumption that long-term control over user credentials is the highest priority for consumer apps).
Grok Leading open-source TypeScript libraries (@simplewebauthn/browser + server) for direct, low-level WebAuthn/passkey implementation; high maturity, active maintenance, no vendor lock-in or runtime costs—ideal for practitioners wanting full control and customization in consumer apps.
Claude The de-facto standard TypeScript library for building passkeys directly on the WebAuthn API — free, battle-tested, tracks spec changes fast, and gives full control with zero per-MAU cost; the right pick when you already have an auth system and just need credential ceremonies done correctly.
Where SimpleWebAuthn falls short, per the models
- Claude It's a library, not a service — no user store, session management, fallback flows, or cross-platform mobile SDKs; you own all of that, which most small consumer teams underestimate.
- Gemini Requires substantial development effort to build frontend UI components, database schemas, session management, and fallback flows from scratch.
- Grok Requires building your own backend auth infrastructure, session management, recovery, and UI (more engineering effort than hosted services).
Top alternatives per the models: Stytch · Clerk · Corbado · Hanko
Premier open-source WebAuthn/passkey library suite providing clean, highly maintained Relying Party server and client primitives without commercial license fees or vendor lock-in; near-tie with Corbado for self-hosted architecture.
Where SimpleWebAuthn falls short, per the models
- Gemini Not for teams wanting pre-built mobile UI or turnkey identity management, as developers must handle mobile native bindings, database schemas, and session handling manually.
Top alternatives per the models: Corbado · Stytch · Apple Authentication Services + Android Credential Manager · Descope
