Three problems, one gate
ShipGauge tells you if you should ship — not just what you spent.
Bill shock
A dozen AI features, one giant invoice. You can't tell which feature burned the budget.
Silent regression
A prompt tweak drops quality 8%. Nobody notices until users complain three days later.
Tool sprawl
Langfuse is heavy, Promptfoo has no prod budget, LLMeter has no eval. You install three tools or give up.
How it works
SDK → CI → Production guard
Tag with SDK
Add feature_id to every LLM call with 5 lines of code. See per-feature spend in minutes.
Gate in CI
Run smoke evals on every PR. Block merges when pass rate drops or cost spikes.
Guard production
Set per-feature budgets. Soft warn at 80%, hard block at 100%. No runaway agents.
Why ShipGauge vs the rest
Promptfoo tells you if it's worse. LLMeter tells you if it's expensive. ShipGauge tells you if you should ship.
