What to know before choosing
Good fit
Developers who run coding agents such as Claude Code, Codex, Cursor, Antigravity CLI, Kiro, Hermes, or OpenClaw and want dangerous tool calls stopped before they execute.; Individual developers who want a free local monitor with no account and no credit card, covering core pre-execution secret-flow blocking.; Teams that want a local decision history and audit view of agent activity without sending tool-call data to a vendor cloud.
Limits and trade-offs
Windows users, since the system requirements state Windows is not supported yet and the supported machines are macOS Apple Silicon and Linux x86_64.; Machines below the stated requirements, since the local model needs 16 GB of memory minimum and 24 GB recommended plus 15 GB of free disk.; Organizations that need compliance reporting, air-gap or zero-telemetry deployment, managed installation, and support SLAs, since those are Enterprise-only items on the pricing section.

A closer look at Harden AIF
Harden AIF (Agentic Integrity Foundation) is a local security layer that checks AI coding agent tool calls on the developer's own machine before they execute, allowing, blocking, redacting, or steering risky actions, with a free tier for individual developers and a custom Enterprise tier.
Editorial guidance based on published documentation. The workflow below is a suggested starting point, not a measured product result.
When to choose Harden AIF
- Developers who run coding agents such as Claude Code, Codex, Cursor, Antigravity CLI, Kiro, Hermes, or OpenClaw and want dangerous tool calls stopped before they execute.
- Individual developers who want a free local monitor with no account and no credit card, covering core pre-execution secret-flow blocking.
- Teams that want a local decision history and audit view of agent activity without sending tool-call data to a vendor cloud.
When to choose something else
- Windows users, since the system requirements state Windows is not supported yet and the supported machines are macOS Apple Silicon and Linux x86_64.
- Machines below the stated requirements, since the local model needs 16 GB of memory minimum and 24 GB recommended plus 15 GB of free disk.
- Organizations that need compliance reporting, air-gap or zero-telemetry deployment, managed installation, and support SLAs, since those are Enterprise-only items on the pricing section.
A practical starting workflow
- Install the free product and run the configuration step to connect the coding agents already on the machine.
- Let Harden check each supported tool call locally before it executes, with actions allowed, blocked, redacted, made safe, or logged.
- Review the local decision history and audit view to see which calls were blocked, changed, or allowed across sessions.
Check before committing
- The pricing and FAQ sections are part of the homepage text read; the guessed pricing and FAQ subpaths return the same homepage text, so no separate pricing or FAQ page is cited.
- Enterprise is shown only as Custom with no amount, so no Enterprise charge fact is recorded; the Free tier is the only priced tier in the structured facts.
Common questions
What problem does Harden AIF solve?
Coding agents can reach the same systems developers can, and Harden analyzes every supported tool call before it executes, since MCP gateways do not block tool access and sandboxing cannot stop an agent from managing a database or VM.
How do I get started with Harden AIF?
Install the free product, run the configuration step, and connect the coding agents used; no account or credit card is required for the free product.
What does the free tier include?
Core pre-execution secret-flow blocking on the machine, support for Claude Code, Codex, Cursor, Antigravity CLI and Kiro, block-and-steer with safe retry, and a local decision store and audit view with no retention cap.
