Better Auth vs Vanta

Better Auth is an open-source authentication and authorization library for TypeScript, distributed under the MIT license. Instead of sending users to a hosted identity service, it runs inside your own backend and stores users, sessions and accounts in your own database through adapters for Drizzle, Prisma, Kysely, MongoDB and plain SQL drivers. It is framework-agnostic, with integrations for Next.js, Nuxt, SvelteKit, Astro, Hono, Express and others, and typed clients for React, Vue, Svelte, Solid and vanilla JavaScript.

The core covers email and password, social OAuth providers and session management; a plugin system adds two-factor authentication, passkeys, magic links, email OTP, username login, organizations with teams and roles, admin tools, multi-session, API keys, JWT, an OIDC provider and more. A CLI generates the schema and migrations each plugin needs. The library is free with no per-user pricing; an optional managed service (free Starter, $20/month Pro) adds a dashboard.

Better Auth suits TypeScript teams that want control over user data and login flows without writing auth from scratch. The trade-off is responsibility: you handle hosting, security updates and email delivery, and the core ships no prebuilt UI components. Clerk and Auth0 provide hosted UI, dashboards and enterprise SSO for a per-user fee; Supabase Auth is convenient if you already use Supabase; Auth.js (NextAuth) is the older open-source option with fewer built-in features.

The project grew quickly in 2024 and 2025 as Lucia was deprecated.

Vanta is a compliance automation and trust management platform founded in 2018 in San Francisco by Christina Cacioppo. It helps companies achieve and maintain security certifications such as SOC 2, ISO 27001, HIPAA, GDPR and PCI DSS by replacing spreadsheets, screenshots and manual evidence gathering with continuous, automated monitoring.

Vanta connects to a company's cloud infrastructure (AWS, Google Cloud, Azure), identity provider, HR system, code repositories, endpoint management and ticketing tools, then runs hundreds of automated tests against the controls each framework requires. When a test fails, it alerts the owner and tracks remediation. The platform also provides policy templates, employee security training, vendor risk management, access reviews and a workspace where external auditors from Vanta's partner network review evidence directly. Trust Center publishes a company's security posture to prospects, and AI-assisted questionnaire automation answers security reviews faster. Pricing is quote-based and depends on frameworks, company size and modules.

Vanta suits B2B SaaS companies whose enterprise deals depend on SOC 2 or ISO 27001, from seed-stage startups getting a first report to scale-ups managing several frameworks. It does not replace internal security ownership, and costs grow with each added framework. Drata is the closest competitor with comparable automation and strong customization, Secureframe emphasizes guided support, and Sprinto targets cost-conscious startups.
