Index codebases, documents, and knowledge sources incrementally to keep AI agents working with fresh, up-to-date context.
Use CocoIndex when source data needs consistent transformation before it reaches a vector database or search index.
Skip if your corpus is tiny and a one-time import script is enough.
It fits teams that want indexing behavior reviewed and maintained like application code.
Skip if your organization prefers a fully hosted no-code ingestion product.
Provides a framework for defining how data moves from sources through transformations into indexes used by AI or search applications.
The Apache-2.0 repository lets teams keep indexing behavior in source control rather than hiding it behind a managed ingestion UI.
Targets the data preparation layer behind retrieval, search, and AI applications rather than general ETL alone.
CocoIndex is used to build repeatable data indexing pipelines for AI and search applications.
Yes. The repository is Apache-2.0 licensed.

Asset-based data pipeline orchestration with a built-in catalog
RAG and search projects often start with a notebook that loads files, chunks text, embeds records, and writes to a database. That path breaks when sources change, indexing needs to run repeatedly, or multiple developers need to understand what data produced a given answer.
No. It helps prepare and index data; you still choose the storage or search backend that serves queries.
