Subscription-Auth Aware Agent Harness Gateway for Cost-Controlled Teams
The Zot launch thread surfaced a structural pricing problem in the agent ecosystem: API billing costs heavy users thousands while subscription plans like Claude Max are massively cheaper, but third-party harnesses lose access to subscription auth as vendors tighten terms (ACP changes already announced for June). Teams want harness flexibility without API-rate billing. A gateway that legitimately maximizes subscription entitlements across tools, with per-seat budget observability, addresses a pain every heavy user in that thread described.
Problem Statement
A team of eight runs mixed harnesses: some on Claude Max subscriptions, some burning API keys. Costs differ by an order of magnitude for the same work, entitlement quotas (weekly limits) expire unused on some seats while others overflow to API billing, and no dashboard shows any of it. Finance sees a number; engineering sees nothing.
The Idea
A cost-governance gateway for agent usage that routes work across subscription entitlements and API keys per policy, with per-developer spend observability and entitlement-aware scheduling.
Why Now
Vendor pricing changes in mid-2026 (ACP drawing from the same budget as SDK usage) are actively breaking third-party harness cost models, and HN commenters now warn each other that API billing for coding racks up thousands of dollars versus subscriptions. Engineering managers have no tooling to see or steer this spend.
Target User
Engineering managers and platform leads at companies with 5 to 100 developers using AI coding subscriptions and APIs simultaneously
Target Market
AI spend management and developer productivity tooling

The missing tool is a cost anomaly detector that catches spikes within hours (not at month-end) and traces them to the specific resource and commit that caused them.
