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.
Keel features
- Schema-driven data model. Define data models, actions, and permissions in a clear schema that generates APIs and internal tools.
- TypeScript extensions. Write custom functions, jobs, and durable functions in TypeScript with full type safety.
- Version-controlled environments. Create multiple environments, branch deployments, and PR previews with audit trails.
- Built-in testing framework. Generate type-safe end-to-end tests from the schema for actions, functions, and jobs.
- Instant internal tools. Automatically generate UI tools for ops teams that stay in sync with schema changes.
- Serverless infrastructure. Managed, multi-region PostgreSQL and serverless runtime scales from first to millionth user.
