Built by developers, for developers
FluxKit is an opinionated SaaS starter kit that eliminates the setup tax. We've made the hard choices so you can focus on what makes your product unique.
Developer First
Every decision is made with DX in mind — TypeScript throughout, clean structure, and zero magic.
Auth You Can Trust
Better Auth gives you a battle-tested authentication system with email, OAuth, and magic links.
Real-time Backend
Convex powers a reactive serverless backend — your UI stays in sync automatically.
Production Ready
Ships with Sentry, rate limiting, transactional email, and billing pre-configured.
Everything you need to ship production SaaS
FluxKit wires up all the hard parts — authentication, billing, real-time data, email, and monitoring — so you can focus on building your product.
Auth & teams, fully configured
Better Auth handles email/password, magic links, social OAuth, and password resets. Organizations with member invites and role management are built in.
Better Auth
Email + password, magic links, social OAuth, and password reset — fully configured.
Organizations & Teams
Invite members, manage roles, and handle multi-tenant access out of the box.
Convex Backend
Real-time serverless backend with reactive queries — no REST endpoints to write.
Real-time by Default
Data updates propagate instantly across all clients with zero polling or websockets setup.
Billing, email & monitoring included
Polar handles checkout and billing flows. Resend or Brevo sends transactional emails. Sentry catches errors. Upstash Redis rate-limits your APIs. All pre-configured.

Transactional Email
Resend or Brevo integration for verification, magic links, invitations, and password resets.
Error Monitoring
Sentry configured for both client-side and server-side error tracking.
