Forcefield is a fast, lightweight, local-first AI agent runtime and terminal harness written in Go.

It lets developers run AI agents, delegate tasks to subagents, execute tools, and work with multiple model providers from a single terminal environment.

Forcefield supports local inference through Ollama, LM Studio, and llama.cpp, alongside cloud providers including OpenAI-compatible APIs, Google Vertex AI, AWS Bedrock, and Azure.

It runs locally, requires no account or cloud infrastructure, and collects no telemetry.
