Introduction

What is Synclet?

Synclet is a self-hosted data synchronization platform that moves data between databases, APIs, warehouses, and file systems. It ships as a single Go binary, runs on any Linux server or container orchestrator, and runs connectors that implement the Airbyte Protocol: run Airbyte connectors without Airbyte. The connectors and versions tested are listed under Tested with.

You define sources, destinations, and connections through a web dashboard or API. Synclet handles schema detection, incremental synchronization, state management, scheduling, and monitoring — so you can focus on what to sync rather than how.

Who is Synclet For?

• Data engineers who need a lightweight, self-hosted alternative to managed ELT platforms.
• Teams already using Airbyte connectors who want to run the same connector images with less operational overhead.
• Organizations with strict data residency requirements that need all data movement to happen within their own infrastructure.
• Developers running one-off or periodic data transfers who want a simple setup without complex infrastructure.

Key Features

• Airbyte Protocol connectors — Run source and destination images that implement the Airbyte Protocol, plus Synclet’s own Go connectors. Each image keeps its own license, see Connector licenses.
• Multiple Execution Modes — Run connectors via Docker, Kubernetes, or the local CLI depending on your environment.
• Incremental Sync — Only transfer new or changed records. Synclet tracks sync state automatically between runs.
• Stream Configuration — Select individual streams, choose sync modes (full refresh or incremental), pick specific fields, and rewrite destination namespaces or stream names.
• Workspaces — Organize sources, destinations, and connections into isolated workspaces, one per team of your organization.
• Role-Based Access Control — Three built-in roles per workspace: Admin, Editor, and Viewer.
• OIDC Single Sign-On — Authenticate users through any OpenID Connect provider (Google, Okta, Keycloak, and others).
• Notifications — Get alerted on sync failures and completions via Slack, Email, or Telegram.
• Dashboard & Metrics — Monitor sync status, job history, duration, and record counts from the built-in web UI. Export Prometheus metrics for external monitoring.
• Config Backup & Restore — Export and import your entire Synclet configuration for disaster recovery or environment migration.
• API Keys — Automate operations and integrate with CI/CD pipelines using programmatic API access.

How It Works

Synclet follows a straightforward three-step workflow:

1. Configure a source — Pick a connector (e.g., PostgreSQL, Stripe, Google Sheets), provide credentials, and test the connection. Synclet discovers the available schemas and streams automatically.
2. Configure a destination — Set up where the data should land (e.g., BigQuery, Snowflake, a CSV file). Test that Synclet can write to it.
3. Create a connection — Link a source to a destination. Select which streams to sync, choose sync modes, set a schedule (cron or manual), and run your first sync.

Next Steps

• Installation — Set up Synclet on your machine or server.
• Quick Start — Create your first data sync in under 5 minutes.
