Monitoring is free. Forever.
Every plan watches every agent: cost, latency, errors, and a measured figure for what caching would save you. You only pay to switch optimisation on — and we meter the AI spend we actually optimise, not how much you log. It works out at roughly 10% of the spend we work on.

See everything. Pay nothing.
Point your stack at the proxy and Vigil logs every call — cost, latency, errors, prompt injections, PII leaks — across every provider you use, plus a measured figure for what caching would have saved you. Optimisation is included on 1 agent up to $100 a month, so the upgrade decision gets made on your numbers rather than our estimate.

Switch it on for the agents that cost you the most.
The same monitoring you already had, now acting on it: optimisation runs on 3 agents against up to $300 of optimised spend a month. The Threats and PII pages and 3 seats come with it, and the rest of your fleet keeps the free monitoring it already had.

Pro
$99/mo excl. VAT
For a fleet in production, not an experiment.
Optimisation across 10 agents and up to $1,000 of optimised spend a month, with 90 days of history — enough to argue with a quarterly bill rather than guess at it. Unlimited seats means the whole team reads the same numbers, and support answers while the spike is still happening.

Supreme
$299/mo excl. VAT
Every agent optimised. Nothing left unlogged.
The ceilings come off: optimisation on every agent you run, unlimited logged calls, and a full year of history so this quarter can be compared honestly against last year's. Up to $3,000 of optimised spend a month, and the overage line reads none.

Spend ceiling, retention and overage are negotiated rather than listed — everything on this page, sized to your contract instead of ours. Unlimited seats and a named contact who already knows your account.
