CocoIndex

Transform your data for AI workloads with exceptional performance and developer velocity. CocoIndex is an open-source ETL framework with a Rust-powered core engine, designed specifically for modern AI applications including semantic search, RAG, and knowledge graphs.

Key advantages:

• Minimal code required - Get started with just ~100 lines of Python using declarative dataflow syntax
• Incremental processing - Automatic recomputation optimization that only processes necessary portions while reusing cached results
• Native building blocks - Standardized interfaces for sources, targets, and transformations with 1-line component switching
• Single source of truth - Define once, run in multiple modes: batch, live updates, or fast preview runs

CocoInsight companion tool provides best-in-class data lineage and observability, helping you understand your pipeline step-by-step without requiring deep data expertise. This significantly boosts developer velocity and lowers barriers to data engineering.

Production-ready from day zero with automatic schema management, cloud-native architecture, and enterprise features including VPC deployments, guaranteed SLA, and data governance. Available as open-source (Apache 2.0) for self-hosting, with free personal use options and enterprise support tiers.
