Obelisk vs Clerk, honestly
Clerk is known for beautiful, drop-in React and Next.js UI components that make adding auth to a frontend fast. Obelisk is a passkey-first identity and security plane built around one idea: security you can prove, not just promise. This page compares the two fairly — Clerk is a genuinely good product for teams who want polished, pre-built sign-in UI in a React/Next.js app, and we say so plainly below.
The short version: if your priority is provable security on the login itself — a live Rating, tamper-evident receipts, passkey-first by default, and zero secrets in your own app — Obelisk is built for exactly that. See the full field →
Where Clerk shines
Clerk genuinely shines at developer experience for React and Next.js: gorgeous pre-built <SignIn /> components, organizations and user-management UI out of the box, and a fast path from zero to a working sign-in screen. If your priority is shipping a polished frontend auth UI quickly in a JavaScript app, Clerk is an excellent, well-loved tool.

Why teams choose Obelisk
The differences below aren't cosmetic — they're structural choices that move security from "trust us" to "verify it."
- Passkey-first by default. Passwordless via WebAuthn/FIDO2 is the default path, not an add-on — the secret half of the credential never leaves the device, so it can't be phished, stuffed, or stolen from a database.
- A live security Rating on the login itself. The Obelisk Rating is a real-time 0–100 security score shown on the sign-in surface — verifiable and continuously scored. No other identity provider renders a live security score on the login.
- The verified seal embed. A drop-in login card (
obeliskgate.com/embed/seal.js) that shows the live Rating and is provably authentic — your login proves its own security in front of your users. - Tamper-evident, hash-chained receipts. Every sign-in, token, and grant emits a signed, hash-chained receipt. The chain can't be quietly rewritten, so the audit trail is something you can verify, not just trust.
- Zero project-side secrets — one-DB model. Relying-party apps hold no credentials. Your app stores no password hashes, MFA seeds, or reset tokens, because Obelisk hands you a verified identity. You can't leak what you don't store.
- Pay-per-passage pricing. The Gate Toll bills per audited sign-in (a passage), not per seat or per monthly-active-user — and every billable passage is itself a signed receipt.
Together these make the login the strongest part of your stack, with a posture anyone can check. See the full trust case →
Frequently asked questions
Is Obelisk a Clerk alternative?
Yes. Both give you a complete sign-in experience without building auth from scratch. The difference in emphasis: Clerk leads with drop-in React/Next.js UI; Obelisk leads with passkey-first security you can prove — a live Rating on the login, verifiable receipts, and zero project-side secrets. If security posture and auditability are the priority, Obelisk is the stronger fit.
Can I migrate from Clerk to Obelisk?
Yes. Obelisk is a standards-based OpenID Connect provider, so you integrate it the same way you'd integrate any OIDC IdP — point your app at Obelisk for login and map the verified subject id to your own user records. Because Obelisk uses the zero-project-secrets model, migrating also lets you drop credential storage from your own database.
Does Obelisk have pre-built UI like Clerk?
Obelisk gives you a hosted, immersive sign-in experience plus a drop-in verified seal embed. It's a different shape from Clerk's React component library — Obelisk owns the secure login surface so you don't render credential UI at all.
