Frequently asked questions
What is an AI agent?+
An AI agent is a system built on large language models that can plan and execute multi-step tasks — writing code, browsing the web, calling APIs or running business workflows — with limited human input.
What is the best AI coding agent?+
Cursor and Claude Code lead for daily engineering work, Devin and OpenAI Codex target autonomous long-running tasks, and OpenHands, Cline and Aider are the strongest open-source options.
What is the best open-source AI agent?+
OpenHands, Cline, Aider, OpenCode and Browser Use are the most active open-source agents in 2026 — each targeting a different workflow (coding, terminal, browser).
Are browser agents safe?+
Browser agents run inside sandboxed sessions or your own browser. Only give them access to accounts you're comfortable exposing, use human-in-the-loop confirmation for sensitive actions, and prefer tools with clear permissions and audit trails.
How does ToolHund score AI agents?+
The ToolHund Score weighs ease of use, capability, pricing value, community traction and openness. Agents get extra weight for transparency, controllability and honest documentation of limitations.
