Kinde
Modern authentication platform with pre-built components, social login, and organization management for B2B and B2C apps.
Best for early-stage B2B and B2C apps that need modern auth with organizations and social login out of the box.
Use Cases
Free Tier
7,500 monthly active users, social login, email/password, unlimited M2M tokens
How to Maximize the Free Tier
Kinde's 7,500 MAU free tier is enough for a beta launch or early-stage product. Enable social login (Google + GitHub) immediately to reduce friction and offload password management. Use unlimited Machine-to-Machine (M2M) tokens for API authentication — a rare free-tier perk. Watch the organization count: the free plan supports basic orgs but advanced roles and permissions require the paid plan. If you hit the MAU cap, review your session duration limits — shorter sessions can inflate MAU counts if users log in multiple times per month.
Getting Started
Sign up at kinde.com → create a business → choose B2B or B2C → add an app (Next.js, React, SPA, etc.) → copy the frontend/backend API keys → install the Kinde SDK → wrap your app with the Kinde provider → add login/logout components → verify social login providers in Settings.
Pros
- Organization support: Built-in multi-tenant org management on the free tier — teams, members, and roles without extra configuration
- M2M tokens: Unlimited Machine-to-Machine tokens on the free plan for API-to-API authentication, a feature often gated behind paid tiers elsewhere
- Modern UX: Clean, modern auth components and dashboard — feels current compared to Auth0's dated interface
Cons
- MAU cap: 7,500 MAU is below Clerk (10K) and Logto (50K) — tight if you have highly engaged daily users
- Young platform: Kinde is newer than Auth0 or Clerk — fewer community resources, stack overflow answers, and third-party tutorials
- Pricing jump: Moving beyond the free tier means $35+/month — a significant jump for indie developers
