Your website shines
our API works
We handle the complex backend plumbing — authentication, structured events, real-time errors, and Stripe payments. You focus on building a beautiful product. All powered by one simple, type-safe API.
Everything you need
One SDK. Infinite possibilities.
Stop stitching together dozens of services. Syntro gives you auth, events, analytics, and payments — all through one API key.
Authentication
Register, login, and manage end-users with JWT tokens. Email + password or OAuth.
Custom Events
Track any business event. Cart adds, signups, form submissions — analyze them all.
Error Tracking
Catch errors in real-time. See frequency, last occurrence, and detailed metadata.
Stripe Payments
Create checkout sessions with one function call. Webhooks handled automatically.
JavaScript SDK
npm install syntro-sdk and you're ready. Zero dependencies, TypeScript-first.
API Documentation
Interactive docs with code examples for every endpoint. Build with confidence.
Infrastructure
Cloud hosting, built in.
Deploy databases and runtimes in seconds. MariaDB, PostgreSQL, Redis, MongoDB, and Node.js — all managed through your Syntro dashboard.

Build the future,
leave the plumbing to us.
