Frequently asked questions about Harden
What AI coding agents does Harden AIF support?
Claude Code, Cursor, Codex, Hermes, OpenClaw, Kiro, and Antigravity CLI. Documentation provides setup guidance for each.
How does Harden prevent data exfiltration?
A purpose-trained model evaluates each action against your original task intent and session history. For example, if an agent tries to upload data containing customer information, Harden traces it back to earlier edits and blocks the transfer.
Is Harden free?
Harden AIF is completely free for individual developers. Enterprise and organizational pricing is not publicly available.
How does Harden work?
You install AIF locally and connect it to your coding agent. It runs in the background, checking actions in real time and logging decisions to a local dashboard.
