FrontierAgent is an open-source agent runtime and terminal application that executes long-horizon research and file-based work tasks.
The tool addresses the need for agentic systems that can handle complex, multi-step workflows without heavy infrastructure requirements. It provides two native execution modes: ReAct, where a single stateful agent researches, reads files, writes deliverables, and runs commands iteratively within a task-scoped sandbox; and Agent Team, where a coordinator maintains a task board, delegates work to parallel sub-agents, collects their reports, and synthesizes results. The framework separates its workflow engine, tools, evaluation layer, and framework components so each can be reused independently. Installation requires only one command on macOS and Linux with no preinstallation or hard Docker dependency.
Developers should choose this tool if they need a terminal-native agent framework for research-oriented or file-manipulation tasks that benefit from either single-agent reasoning or multi-agent coordination. The project suits scenarios where agents need to interact with the filesystem, execute commands, and iterate on complex problems. The framework is designed to work with compatible model endpoints, including the Apodex API, and can integrate with alternative model providers through standard interfaces.
The project maintains active development with regular updates to its core workflows and evaluation capabilities. The codebase is organized to keep framework, tools, and evaluation concerns modular and independently reusable. Documentation is structured to guide users through installation, workflow selection, and evaluation setup. The team provides multiple channels for community engagement and feedback on agent behavior and framework improvements.
