Better Auth vs Logsign

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.

Logsign is a Turkish cybersecurity company headquartered in Istanbul that builds a unified security operations platform. Its product brings SIEM, SOAR, threat intelligence and compliance reporting together, so security teams can collect logs, detect threats and respond to incidents in one system instead of integrating several separate products.

The SIEM side collects and normalizes logs from firewalls, servers, endpoints, network devices, cloud services and applications, correlates them with rules and threat intelligence feeds, and raises prioritized alerts. The SOAR side runs automated playbooks for investigation and response, such as enriching an IP address, isolating a host or blocking an indicator through integrations with security tools. Dashboards, case management and built-in compliance reports support audits under frameworks such as ISO 27001, PCI DSS and GDPR, and the platform also addresses Turkish requirements including KVKK and log retention under Law No. 5651. It is deployed on-premise or in private environments and sold through partners with custom, license-based pricing.

Logsign suits mid-sized enterprises, public institutions and security service providers that want an integrated SIEM and SOAR with local support and Turkish-language service. Large global SOCs may prefer the scale and ecosystem of Splunk, Microsoft Sentinel or IBM QRadar, while budget-conscious teams with in-house skills often evaluate the open-source Wazuh. Logsign's advantage is a single platform combined with local compliance knowledge.
