TrueFoundry has launched TrueForge, an open-source agent harness that lets developers build and run AI agents using models from different providers, positioning it as an alternative to Anthropic’s Claude Managed Agents.
The San Francisco-based enterprise AI infrastructure startup was founded in 2021 by a team that included former Meta engineers. It initially focused on software for deploying machine-learning models before expanding into generative AI infrastructure.
An agent harness is the software layer that manages how an AI agent interacts with the underlying model and external tools. Anthropic’s Claude Managed Agents provide this functionality as a hosted service for long-running agent workloads on the Claude Platform.
TrueForge can run on an enterprise’s own infrastructure and supports OpenAI and Anthropic models as well as more than 20 additional models, according to TrueFoundry. Developers can bring their own Model Context Protocol (MCP) servers and API keys. The company is also offering a hosted version with usage-based pricing.
TrueFoundry says TrueForge can reduce total agent operating costs by 50%, although its published benchmark shows different savings depending on the model and harness being compared.
