The project is three days old, auth is off by default, and no detection accuracy is published.\n\n**NVIDIA NeMo Guardrails.** Apache-2.0, 7,200 stars and nine releases between 9 October 2025 and 16 September 2026. Usage telemetry and a heartbeat every 10 minutes to NVIDIA by default.\n\n## Before you call either\n\n### AgentGate\n\n1. Create a session with the user's real goal first. The goal-alignment head scores every later call against it\n2. Pass earlier tool results in `history_override` with `untrusted: true` for web or email content, or the injection head sees only the action\n3. On `ask`, stop and tell the user the `decision_id`. Polling `/v1/decisions/:id` needs the dashboard key\n4. Treat `allow_with_checkpoint` as allow and keep the `checkpoint_id` for an undo\n5. Expect HTTP 404 with `not_found` for an unknown session and 401 when the owner has set an agent key\n\n### NVIDIA NeMo Guardrails\n\n1. Set NEMO_GUARDRAILS_NO_USAGE_STATS=1 before import unless you want deployment metadata sent to NVIDIA every 10 minutes\n2. Use IORails for plain input and output checks. LLMRails and Colang are for dialogue flows a tool-calling agent rarely needs\n3. Pin nemoguardrails==0.24.1. 0.24.0 changed message passing to messages= and removed inline config from /v1/checks\n4. Call /v1/checks with a config_id loaded on the server and branch on the RailOutcome\n5. Put the server behind your own gateway. It has no auth or rate limiting\n\n## Questions\n\n### Which is better for AI agents, AgentGate or NVIDIA NeMo Guardrails?\n\nNVIDIA NeMo Guardrails scores 68.4 (B) on agent readiness against AgentGate's 48.5 (D), and leads in 6 of 7 scored categories.\n\n### Can an agent call AgentGate and NVIDIA NeMo Guardrails without installing anything?\n\nAgentGate runs on your own machine, with no hosted endpoint listed. No hosted endpoint is listed for NVIDIA NeMo Guardrails.\n\n### Are AgentGate and NVIDIA NeMo Guardrails open source?\n\nYes. AgentGate is open source (MIT). NVIDIA NeMo Guardrails is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/agentgate-vs-nemo-guardrails.json, and with the fewest tokens: https://www.anchorterminal.com/compare/agentgate-vs-nemo-guardrails.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"agentgate\", \"b\": \"nemo-guardrails\"}`.
