Compare

One question runs through every comparison: where does enforcement happen?

Agent governance tools mostly split along a single axis. Some govern the suggestion: they sit near the model and shape what it sees and proposes. Some govern the execution: they sit on the real call and decide whether it happens. AgentValet is the second kind, and the reason is custody: it holds the credential, so its decision is the only route to the platform. These pages compare the approaches honestly, including where the other tools genuinely win.

vs Tenure
A self-hosted proxy on the model call: governed memory, tool filtering, suggestion screening. Strong at context governance, but the agent keeps its own keys. The closest vocabulary overlap, and the clearest chokepoint difference.
vs Permit.io
Authorization-as-a-service for your application's users. Excellent at in-app permissions, which AgentValet does not do. The difference: a policy check your code opts into is not custody of the key.
vs MCP gateways
The category page. Catalogues, tool filters, and logs are useful operations work, but a gateway governs only the traffic routed through it, and the secrets still live outside it.
vs API keys in .env
The real competitor. Undefeated on convenience, and genuinely fine for low-stakes experiments. This page is honest about where that stops.

The short form of all four: model-call gateways advise, credential brokers enforce. The long form, with the diagram, is in the enforcement section of the main page.

Or skip the reading and test it.

One command registers an agent, one grant scopes it, and the first governed call writes its audit row. You will have your own comparison inside ten minutes.
