Summary

Rapida is an open-source, end-to-end platform for orchestrating conversational voice AI agents. It targets developers and enterprises seeking to build, deploy, and manage scalable voice applications with real-time audio processing, LLM integration, and comprehensive monitoring. The platform offers a reliable, observable, and customizable framework for production workloads.

How It Works

Built in Go, Rapida leverages gRPC for efficient, low-latency bidirectional audio streaming and communication. Its architecture centralizes orchestration, managing routing, state, parallelism, and tool execution across various channels (e.g., Phone, Web, WhatsApp). It supports a flexible pipeline including audio preprocessing (VAD, noise reduction), Speech-to-Text (STT), LLM reasoning (agnostic to specific models), and Text-to-Speech (TTS), enabling adaptable voice agent development.

Quick Start & Requirements

Setup requires Docker and Docker Compose. Users must clone the repository, create a ~/rapida-data/ directory, and grant Docker group access. Services are built using make build-all and started with make up-all. Key dependencies include PostgreSQL, Redis, and OpenSearch. The UI is accessible at http://localhost:3000. Detailed documentation is available at https://doc.rapida.ai.

Highlighted Details

• Real-time Orchestration: Low-latency audio streaming and processing via gRPC.
• LLM-Agnostic: Integrates with any LLM, including OpenAI, Anthropic, and open-source models.
• Production-Grade Reliability: Features built-in retries, error handling, and call lifecycle management.
• Full Observability: Provides call logs, streaming events, tool traces, latency metrics, and dashboards.
• Flexible Tooling: Enables custom tools and backend integrations for agent actions.

Maintenance & Community

The project provides a Contribution Guide. Security disclosures should be directed to contact@rapida.ai. No specific community channels (like Discord/Slack) or roadmap links are provided in the README.

Licensing & Compatibility

Rapida is licensed under GPL-2.0, with a condition requiring the Rapida logo to remain visible in UI components for open-source users. A commercial license is available for enterprises seeking to remove branding, use the software in closed-source applications, or make private modifications.

Limitations & Caveats

Open-source usage is subject to the GPL-2.0 license, including mandatory logo visibility. Future license terms may change, potentially impacting subsequent releases. The setup process requires specific directory permissions for Docker.
