Sling Data Platform is a self-hosted data integration platform built for data engineers who need reliable, high-performance EL (Extract and Load) without per-row pricing, vendor lock-in, or heavyweight infrastructure. At its core, Sling is a single Go binary that connects to 40+ databases, file systems, and REST APIs — including PostgreSQL, MySQL, Snowflake, BigQuery, Redshift, DuckDB, Oracle, SQL Server, S3, GCS, Azure Blob, Salesforce, Stripe, GitHub, and more. The binary runs anywhere: laptop, container, VM, or cloud agent, with no JVM, Python environment, or Docker stack required. The platform wraps the open-source CLI engine (AGPLv3, 5,000+ GitHub stars) with a web UI for authoring replication configs, scheduling jobs, monitoring pipeline health, and managing self-hosted agents at scale. Teams get the control of self-hosted infrastructure with the usability of a managed SaaS. Key capabilities: - Full incremental and full-refresh replication modes with schema drift handling - CDC (Change Data Capture) via logical replication for PostgreSQL, SQL Server, Oracle, and MongoDB - Parallel streaming for fast initial loads on large tables - YAML-based configs that are git-native and version-controlled - Pipeline hooks for transformations, notifications, and custom logic - Multi-agent architecture for distributed execution across environments - Observability with volume, freshness, and schema monitoring (Advanced tier) - Native dbt profile compatibility Sling is built for data engineers and platform teams at companies from startups to mid-market who want a predictable, flat-rate pricing model instead of paying per row or per connector. Unlike Fivetran or Airbyte, Sling runs entirely in your infrastructure — no data passes through a third-party control plane. Free to start. CLI Pro and Platform tiers available for teams requiring CDC, schema migration, advanced monitoring, and multi-user collaboration.
