This is the honest one. Cycode AI Guardrails is the closest thing to MoorAI on the market: it also reviews AI agent prompts on the device, hooking the IDE and agent so prompt content stays on the machine. The mechanism is shared — so this comparison isn't about who reviews on-device. It's about openness, framing, and how it's delivered.
MoorAI is open source and standalone (AGPL-3.0, no account), and reports only redacted, content-free signals — governance without surveillance. Cycode AI Guardrails is proprietary, DLP- and complete-visibility-framed, and delivered as one module of the broader Cycode ASPM / software-supply-chain platform.
Both tools intercept at the IDE and agent layer and keep prompt content on the machine — the first rows below are genuinely equal. The differences are that MoorAI is open source and auditable, leads with content-free "governance without surveillance" rather than DLP visibility, and runs as a standalone agent instead of a module inside a larger platform.
| MoorAI | Cycode AI Guardrails | |
|---|---|---|
| Where prompts are reviewed | On the device | On the device (IDE hooks) |
| Prompt content leaves the machine | Never | Never (per Cycode) |
| Coding-agent & MCP interception | ✓ | ✓ |
| Coach / alert / block modes | ✓ | ✓ (report → block) |
| Primary framing | Governance without surveillance | DLP · complete visibility |
| Signals to security team | Redacted, content-free | Security-team visibility |
| Licensing | Open source (AGPL-3.0) | Proprietary |
| Delivered as | Standalone open agent | Module of a broader ASPM platform |
| Account required to start | No (community agent) | Yes (platform) |
The honest take. Cycode is genuinely strong — it has the same on-device, IDE-hook, MCP-aware mechanism, backed by a full ASPM / software-supply-chain platform (SCA, secrets, SAST) and an established security-team buyer. MoorAI's edge is a different one: it's open source and auditable, leads with content-free “governance without surveillance” instead of DLP visibility, and runs standalone — no vendor in the trust path.
