A little curiosity. A world of open source.
THE FIRST COLLECTIONAllSource is an AI-native event store built in Rust, featuring high-throughput ingestion, low-latency reads, and native MCP integration for AI agents. It supports durable event sourcing without Postgres, includes an agent memory engine, and offers community and enterprise editions.
CocoIndex is an open-source incremental indexing framework designed to provide AI agents and LLM applications with continuously fresh context by reprocessing only changed data.
Chroma is an open-source data infrastructure designed for AI, providing vector, hybrid, and full-text search capabilities.
Poolstatis is an agent-native product analytics system modeled after PostHog, designed primarily for coding agents via MCP. It features semantic metrics, funnels, session replay, A/B testing, and answer-first analysis screens for humans.
An all-in-one AI framework for semantic search, LLM orchestration, and language model workflows.
Dolt is a SQL database with Git-style version control: databases can be forked, cloned, branched, merged, pushed and pulled like repositories, while MySQL-compatible clients connect and version control is exposed through SQL system tables and stored procedures.
PageIndex is a vectorless, reasoning-based RAG engine that builds hierarchical tree indexes for long documents and lets an LLM reason through the tree to retrieve relevant sections, avoiding vector databases and chunking.
CheckMyData.ai is an AI-powered database query agent that enables natural language data analysis across PostgreSQL, MySQL, ClickHouse, and MongoDB. It features multi-agent orchestration, rich visualizations, and code-database synchronization.
