Live Oak Hotel receptionist agent

An open-source benchmark and evaluation harness for voice agents. It runs hundreds of simulated callers against a complete agent and scores outcomes such as successful bookings, caller cutoffs, invented tool calls, and data leaks. Its methodology and evaluation sets are open, allowing teams to run the benchmark against their own data.

Booking Microservices is a practical flight-booking system developed by Evangelos Vlachos as a set of .NET 10 microservices. It uses Vertical Slice Architecture, domain-driven design, CQRS, and event sourcing; commands update PostgreSQL or EventStoreDB and publish integration events through Wolverine's durable outbox to RabbitMQ, while consumers use a durable inbox to project read models into MongoDB. Queries read from MongoDB, and synchronous cross-service validation uses gRPC. The repository includes Identity, Flight, Passenger, Booking, and YARP API gateway services, plus .NET Aspire orchestration, Docker Compose and Kubernetes deployment configurations, OpenTelemetry-based observability, OpenAPI documentation, and automated unit, integration, end-to-end, and contract tests.

LiveKit Agents is an open-source Python framework for building programmable, real-time multimodal voice agents that run as server-side participants. It combines speech-to-text, large language models, text-to-speech, and realtime APIs with LiveKit's WebRTC clients, telephony stack, RPC and data APIs, and MCP tool support. The framework provides agent sessions, server-side job scheduling and dispatch, semantic turn detection based on a transformer model, multi-agent handoffs, and tools for voice, text-only, transcription, vision, and video-avatar applications. Agents can be tested with native test integration, including event assertions and LLM-based judges, and can run locally in console mode, in development mode with hot reloading, or in production mode. The framework can use LiveKit Cloud or a self-hosted LiveKit server and is distributed as a Python package with plugins for model providers. The Agents framework is licensed under Apache-2.0; LiveKit turn-detection models use the LiveKit Model License.

Cal.com is a scheduling software platform that provides customizable online booking and appointment management for individuals, businesses, and developers. It is developer-focused and offers an open-source codebase with options for self-hosting or using hosted plans, plus integrations and embedding tools for adding scheduling into applications.

LiveKit Agents documentation is the official documentation resource for building realtime voice, video, and physical AI agents with LiveKit. Maintained as part of LiveKit's documentation, it covers Python and Node.js SDKs, Agent Builder, realtime media and data pipelines, STT-LLM-TTS processing, turn detection, interruptions, tool use, multimodal interaction, agent handoffs, telephony, deployment, observability, and model-provider integrations. It also explains how agent servers register with LiveKit, receive dispatch requests, run jobs in rooms over WebRTC, and connect to users through LiveKit Cloud or self-hosted infrastructure. The framework and LiveKit ecosystem are documented as open source under the Apache 2.0 license.
