A distributed stream processing engine written in Rust that lets you write SQL to run stateful, real-time computations over data streams with subsecond results.
cocoindex
AI Development · Data Engineering
An incremental data indexing engine that keeps AI agent context perpetually fresh by reprocessing only what changed.
Fluree DB
Databases
A temporal, verifiable graph database with git-like branching, integrated vector/text/geo search, and RDF/SPARQL/JSON-LD/openCypher support — benchmarked at 10.4x faster than the next database on the full Wikidata dump.
GitLab
Developer Tools · Devops
The complete DevOps platform that unifies Git hosting, CI/CD, issue tracking, and security scanning into a single self-hostable application.
Handy
Productivity · Voice AI
Free, offline, open-source speech-to-text that pastes directly into any app on Windows, macOS, and Linux.
iii
Developer Tools · Devops
Compose, extend, and observe every backend service in real time using three primitives: Workers, Functions, and Triggers.
Maltrail
Monitoring · Security
Detect malicious network traffic using 47+ live threat feeds, heuristics, and a fat-client reporting dashboard — no commercial stack required.
Meetily
AI Assistants · Productivity
Privacy-first AI meeting assistant that transcribes and summarizes your meetings entirely on your local machine — no cloud, no data leakage.
monty
AI Development · Developer Tools
Run LLM-generated Python code safely inside your agent—no containers, no CPython, no compromise—with sub-microsecond startup.

ungoogled-chromium
Browser
Chromium without Google tracking — privacy-focused, drop-in replacement
XPipe
Developer Tools · Devops · Networking
A local desktop hub that unifies SSH, Docker, Kubernetes, VMs, and remote desktops into one interface — no agents, no remote setup.
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.
ART
AI Development
Give your LLM agents on-the-job training—ART lets you apply GRPO reinforcement learning to any multi-step agentic workflow with minimal code changes.
ByteChef
AI Agents · Automation
Unified open-source platform for AI agent orchestration and workflow automation with 180+ connectors, MCP support, and durable execution.
DefGuard
Authentication · Networking · Security
Self-hosted secure remote access that unifies WireGuard VPN, identity management, and connection-level MFA in one open-source platform.
headroom
AI Development · Developer Tools
