ClickHouse
Analytics · Data Engineering · Databases
Open-source column-oriented database that delivers real-time analytical queries on petabyte-scale data with millisecond latency.
Qdrant
AI Development · Databases · Search
Open-source vector database and search engine built in Rust for production-grade AI applications — from semantic search to RAG pipelines and recommendation systems.
LanceDB
AI Development · Databases
Open-source, embedded vector database built on the Lance columnar format for fast multimodal search across billions of vectors, backed by Y Combinator (W23).
codex
AI Code Assistants · Developer Tools
OpenAI's open-source CLI coding agent that reads, edits, and runs code in your terminal using natural language prompts.
agentgateway
AI Development · Developer Tools · Mcp
An open source AI-native proxy that secures, observes, and governs agent-to-LLM, agent-to-tool, and agent-to-agent communication through MCP, A2A, and unified LLM routing.
Quickwit
Monitoring · Search
Cloud-native search engine for logs and traces, delivering sub-second search directly on S3, GCS, or Azure Blob storage at a fraction of Elasticsearch's cost.
SlateDB
Databases · Developer Tools
Embedded KV store built on object storage with zero replication cost
Timeplus Proton
Analytics · Data Engineering
Single C++ binary SQL engine for real-time stream processing, ETL, and analytics on Kafka, Redpanda, and ClickHouse with sub-millisecond latency.
cocoindex
AI Development · Data Engineering
An incremental data indexing engine that keeps AI agent context perpetually fresh by reprocessing only what changed.
Rivet
AI Agents · Developer Tools
Stateful actors as a primitive for AI agents, real-time collaboration, and durable execution — with in-memory state, WebSockets, queues, and scheduling built in.
helix-db
Databases
A graph-vector database built from scratch in Rust that unifies graph traversal, vector search, key-value, and relational storage into a single platform for AI applications.
OpenShell
AI Agents · Developer Tools
The safe, private runtime that lets autonomous AI agents operate in sandboxed environments governed by declarative YAML policies — blocking data exfiltration, credential leaks, and unauthorized network activity before they happen.
Graphite
Code Editors · Design Tools
A free, open source procedural 2D design tool that unifies vector, raster, motion graphics, and generative art in a single node-based nondestructive workflow.
mesh-llm
AI Agents · AI Development
Mesh LLM pools GPUs and memory across every machine you own into one OpenAI-compatible API, so agents tap distributed compute instead of a single GPU box or a metered cloud bill.
herdr
AI Agents · Developer Tools
A terminal-native agent multiplexer that runs Claude, Codex, Gemini, and other coding agents side by side in real, persistent panes you can detach from and reattach to from anywhere.
InfluxDB
Analytics · Databases
Open-source time-series database built for real-time ingest, fast SQL queries, and embedded Python automation — powered by Apache Arrow and Parquet.
liteparse
Developer Tools
A fast, lightweight, open-source document parser that extracts spatial text, bounding boxes, and Markdown from PDFs and Office files — entirely on your machine.
magika
Developer Tools · Security
AI-powered file type detection that identifies 200+ content types with ~99% accuracy in milliseconds using a compact deep learning model.
obscura
AI Agents · Developer Tools
A lightweight, stealthy headless browser written in Rust — drop-in compatible with Puppeteer and Playwright, built for AI agents and web scraping at scale.
Murr
Databases
A RocksDB-based NVMe/S3 cache purpose-built for AI inference workloads — a faster Redis replacement optimized for batch, low-latency, zero-copy reads and writes between data pipelines and inference apps.
Volga
Data Engineering
A Rust-based real-time data processing engine for AI/ML feature computation, built on Apache DataFusion and Arrow — positioned as an alternative to Flink, Spark, Chronon, and OpenMLDB with unified streaming, batch, and request-time execution.
Vibe Kanban
AI Agents · AI Code Assistants · Project Management
A kanban board for planning work and dispatching Claude Code, Codex, Gemini CLI, and eight other coding agents into isolated git worktrees, then reviewing and merging their diffs from one UI.
OpenFang
AI Agents
An open-source "Agent Operating System" built in Rust — a single binary providing a kernel, memory, skills, extensions, and multi-channel runtime for running AI agents, with 1,700+ tests and zero clippy warnings.
