LangChain is an open-source Python framework that provides composable building blocks for chaining LLM calls, tools, retrievers, and memory into production AI applications. It includes LangGraph for stateful multi-agent orchestration and 1000+ integrations with model providers and data stores.

Open-source kanban project management software for self-hosted teams. Kanboard combines drag-and-drop boards, workflow automation, plugin hooks, and a JSON-RPC API in a minimalist PHP application.

Open-source low-code machine learning library for Python. It wraps common training, comparison, tuning, deployment, and drift-check workflows for tabular, time-series, clustering, and anomaly-detection use cases.

Open-source data annotation platform for computer vision datasets. CVAT supports image, video, and 3D labeling workflows, team review, REST API automation, and self-hosted or managed deployment.

Open-source manufacturing line simulator for PackML messaging over MQTT. It emulates PackML state transitions, commands, counters, and machine-speed telemetry for testing industrial data pipelines and SCADA integrations.

Open-source C++ behavior tree framework for robot task planning and execution. It separates runtime tree logic from node implementations, with ROS 2 wrappers and Groot-based debugging for robotics workflows.

Open-source dataset management framework for computer vision datasets. Datumaro provides Python and CLI workflows for converting, validating, merging, filtering, and analyzing labeled data across many annotation formats.

InvenTree is an open-source inventory management system built with Python and Django. It provides intuitive parts management, stock control, BOM management, and supplier tracking for SMEs and hobbyists.

Open-source MCP gateway and Docker CLI plugin for running, grouping, and exposing MCP servers through Docker-managed profiles and catalogs. It powers Docker Desktop's MCP Toolkit and also runs independently against a Docker engine.

Open-source MCP gateway for routing and governing Model Context Protocol servers. It proxies configured MCP servers, applies security plugins to requests and responses, and can scan server reputation before loading them.

MIT AI gateway from Portkey AI that routes traffic across 1,600+ LLM endpoints through one OpenAI-compatible API. Combines routing, virtual keys, guardrails, caching, observability, and MCP gateway support in a Node.js / Go proxy that runs on Docker or Kubernetes.

Open-source LLM gateway from songquanpeng that proxies 30+ providers behind an OpenAI-compatible API with built-in user accounts, token wallets, and hard quota enforcement. MIT-licensed with active feature development continuing in the new-api fork.

Open-source MCP aggregator from metatool-ai that federates upstream MCP servers into namespaced endpoints for MCP clients. Three-level hierarchy of Servers, Namespaces, and Endpoints, with per-endpoint tool ACLs and generic OIDC discovery for admin login.

Cloud-native reverse proxy and load balancer from Traefik Labs with Docker, Swarm, Kubernetes, and Consul service discovery, automatic Let's Encrypt TLS, and a middleware chain for auth and routing. Core is MIT; Traefik Enterprise adds native OIDC and WAF.

Open-source AI chat platform from Danny Avila that mirrors the ChatGPT interface with multi-provider routing, plugins, MCP client, and OpenID Connect login. Docker Compose reference deployment uses MongoDB with optional MeiliSearch for conversation search.

MIT LLM engineering platform from Langfuse for tracing, prompt management, evaluation, and datasets, captured via SDK instrumentation or gateway integration. Core including OIDC SSO is in OSS; advanced RBAC, audit retention, and SCIM sit in the Enterprise tier.

Python-based AI gateway from BerriAI that proxies 100+ LLM providers behind one OpenAI-compatible API with virtual keys, hard-enforced budgets, cost dashboards, and an MCP federation endpoint. Core is MIT; SSO, JWT-to-key mapping, and audit retention sit in LiteLLM Enterprise.

Open-source runtime for ONNX models with hardware-specific optimizations for CPUs, GPUs, and edge devices. Supports inferencing and training across multiple ML frameworks.

Plugin-driven agent written in Go for collecting, processing, and writing metrics, logs, and sensor data. Part of the InfluxData stack with 300+ input plugins covering system metrics, databases, IoT protocols, and cloud services.
