Best Agent Budgeting Tools 2026
Budgeting for agents means two things: setting the number and enforcing it. Most tools do one; sipi.bot does the second.
Set the number
Provider dashboards and usage limits (OpenAI, Anthropic, cloud consoles).
Cost management platforms (CloudZero, Vantage, Datadog).
Enforce it
Gateway budgets (LiteLLM has per-key budgets).
sipi.bot — per-agent ceilings, velocity limits, and approvals enforced before the transaction.
The honest gap
Provider limits are per-provider; gateways are per-route; cost platforms report after. Only a pre-spend layer enforces the dollar across all merchants.
