Apidog vs Better Auth

Apidog is an all-in-one API development platform that puts design, debugging, testing, mocking and documentation in one tool, so a team works from a single OpenAPI-based source of truth instead of passing specs between Swagger, Postman and a docs site. It runs in the browser and as desktop apps for macOS, Windows and Linux, and it markets itself directly as a cheaper Postman alternative.

Designers build endpoints and JSON Schemas in a visual editor; developers send requests over HTTP, GraphQL, gRPC, WebSocket, SOAP and SSE with Postman-compatible scripts; QA builds visual test scenarios, scheduled runs and performance tests; schema-driven mocks need no code; and interactive docs publish with custom domains. Sprint branches, Git connection, a CLI for CI/CD and self-hosted runners round it out. The free plan covers up to four users; Basic, Professional and Enterprise are billed per member, and documentation readers are free.

It fits teams that want to replace Postman plus a separate docs and mock tool. Stoplight and Redocly are stronger for pure design governance, ReadMe and Mintlify produce more polished public developer portals, and Postman has the larger ecosystem. Apidog's mock and docs features are less mature for large public API programs.

Recent releases focus on AI: an MCP server that feeds API specs to Cursor and other AI editors, an MCP client and AI agent debugger, AI test case generation and schema compliance checks. Apidog also offers an EU data region and an on-premises edition. Import a Postman collection during the 14-day trial to compare.

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.
