CocoIndex features

  • Real-time incremental indexing. Reindexes only the changed delta, delivering sub-second freshness at any repo size.
  • AST-based code context. Generates call graphs, hierarchies, symbol tables and semantic indexes directly from source code.
  • Semantic search. Find functions, patterns or intent by meaning rather than plain text grep.
  • Built-in lineage & observability. Tracks every byte back to its source and provides metrics on freshness, throughput and cost.
  • Parallel task scheduling. Executes transformations in parallel by default for low-latency, low-cost processing.
  • Multi-source support. Ingests code, meeting notes, APIs, databases, vector stores, files, video, audio and more.

Metatype features

  • Typegraphs. Programmable virtual graphs that describe all stack components and enable type-safe API composition.
  • Typegate. GraphQL/REST composition engine that compiles, optimizes, caches queries and enforces auth policies.
  • Meta CLI. Live-reloading CLI for one-command deployment to Metatype cloud or self-hosted instances.
  • Multi-language support. Write backend components in TypeScript, Python or Rust and run them via WebAssembly.
  • Reusable components. Install third-party dependencies as reusable modules within typegraphs.
  • Open-source & extensible. Hosted on GitHub with community contributions and a permissive MPL-2.0 license.
