Both are gateways for APIs and MCP. Here is where they differ.
Zuplo is a gateway for APIs, AI and MCP, with spend caps for LLM traffic, API monetization plans and an MCP gateway. SatGate focuses on per-tool budgets for your agents' MCP calls, payment from external agents in Lightning or USDC on the routes you choose, and signed receipts anyone can check.

SatGate
Purpose-built for agent economics. Hard budget caps, per-tool cost profiles, spend governance, fiat-denominated budget governance, and charging external agents in Lightning or USDC.
Zuplo
Gateway for APIs, AI and MCP. Auth, rate limits, spend caps for LLM traffic, and API monetization plans.
SatGate
MCP + economics. Parse MCP tool calls, apply per-tool cost profiles, enforce budgets at the tool level. Cost attribution by tool name.
Zuplo
MCP exposure. Turn your existing APIs into MCP tools with their Server Handler. Great for making APIs agent-accessible.
SatGate
Open-core. Use SatGate Cloud, or run it on your own servers with Enterprise.
Zuplo
Managed or self-hosted. Managed edge, managed dedicated, or self-hosted on Kubernetes.
SatGate gives each agent its own token with a budget and allowed tools, which it can hand on, smaller, to a helper. On the routes you choose, external agents pay in Lightning or USDC before they get in.
FAQ
Zuplo is a gateway for APIs, AI and MCP, with spend caps for LLM traffic, API monetization plans and an MCP gateway. SatGate focuses on per-tool budgets for your agents’ MCP calls, scoped delegation, payment from external agents in Lightning or USDC, and signed receipts anyone can check.
No. Rate limits control request volume, not business cost. AI agents need dollar-denominated, per-agent, and per-tool controls so expensive calls can be capped before spend occurs.
Yes. SatGate can be deployed as the economic policy layer in front of, behind, or alongside an existing API gateway so teams can keep API management while adding agent spend governance.
