Lemonade is an open-source local AI platform that enables users to run large language models, image generation, speech recognition, text-to-speech, and AI agents directly on their own devices. Built with a local-first approach, it prioritizes privacy by keeping AI processing on local hardware while offering the flexibility to connect to cloud models when needed.

The platform includes an AI runtime, graphical interface, command-line tools, SDK, and OpenAI-compatible API endpoints, making it suitable for developers, businesses, AI enthusiasts, and organizations that want to build or deploy AI applications without relying entirely on cloud services. Lemonade supports Windows, macOS, Linux, Docker, and several Linux distributions, making it accessible across a wide range of environments.

Features

Local AI Runtime

Lemonade runs AI models directly on local hardware, allowing users to work with AI while keeping data on their own devices. This approach improves privacy and reduces dependence on cloud services.

Multi-Modal AI

The platform supports text generation, image creation, computer vision, speech recognition, text-to-speech, transcription, embeddings, and coding assistance through a unified interface.

OpenAI-Compatible API

Developers can connect existing OpenAI-compatible applications to Lemonade with minimal configuration, making it easier to integrate local AI into current workflows.

Model Manager

Users can browse, download, import, organize, and manage AI models from the Lemonade registry or import compatible GGUF models from external sources such as Hugging Face.

AI Agent Support

Lemonade supports coding agents, productivity tools, MCP servers, and AI assistants that can interact with local models for development and automation tasks.

SDK and CLI

The platform includes an SDK and a powerful command-line interface that enables developers to automate workflows, benchmark models, and manage AI environments.

Self-Hosting

Users can deploy Lemonade as a local or network-accessible AI server, making it suitable for personal use, development teams, or organizations that require private AI infrastructure.

Cross-Platform Support

Lemonade works on Windows, macOS, Linux, Docker, and multiple Linux distributions, providing flexibility for different hardware environments.

How It Works

Step 1: Install Lemonade on your supported operating system.

Step 2: Launch the local AI service and access the built-in GUI or command-line interface.

Step 3: Download or import AI models using the Model Manager.

Step 4: Run chat, image generation, speech processing, coding assistants, or AI agents locally.

Step 5: Connect your applications using the OpenAI-compatible API or SDK.

Step 6: Optionally expose your AI server to other devices or integrate cloud models when needed.

Use Cases

Developers can build AI-powered applications using local models.

Businesses can deploy private AI infrastructure without sending sensitive data to external cloud providers.

Software engineers can use coding assistants with locally hosted AI models.

Researchers can experiment with different AI models on their own hardware.

Organizations can self-host AI services for internal teams.

Automation specialists can connect Lemonade to AI agents and workflow automation tools.

Privacy-conscious users can interact with AI while keeping their data on local devices.

Pricing

Lemonade is free to use and is available as an open-source platform. Users can install and run the software locally without subscription fees. Some optional cloud services or third-party integrations may have separate pricing outside the Lemonade platform.
