SatGate vs Bifrost

Both are AI gateways. One routes calls. The other governs spend.

TL;DR

Bifrost is excellent at routing LLM calls efficiently across providers with minimal latency. SatGate is built for economic governance — hard budget enforcement, per-tool cost attribution, and monetization. If your agents need to call LLMs fast, use Bifrost. If you need to control what they spend, use SatGate.

Key Differences

Budget Enforcement

SatGate

Hard enforcement. When budget is exceeded, requests are blocked. No "oops" moments. The CFO knows exactly what will be spent.

Bifrost

Soft limits. Budget tracking with alerts, but requests still go through. You find out what you spent after the fact.

Cost Attribution

SatGate

Per-tool granularity. See exactly which MCP tool, which agent, which team spent what. Chargeback reports by cost center.

Bifrost

Request-level tracking. You see which requests were made, but no native cost attribution per tool or team.

Primary Use Case

SatGate

Economic governance. Protect APIs from runaway agent spend. Monetize API access. Control budgets at the request level.

Bifrost

LLM routing. Efficiently route calls across multiple LLM providers. Automatic failover and load balancing. Minimize latency.

When to Use Each

Use SatGate when...

  • You need to enforce hard budget caps on agent spend
  • You want per-tool cost attribution for chargeback reporting
  • You're monetizing API access (charging per call)
  • You're protecting REST APIs, MCP tools, or any HTTP endpoint
  • The CFO asks "how do we control AI spend?"

Use Bifrost when...

  • You need to route LLM calls across multiple providers
  • You want automatic failover if one provider goes down
  • You're optimizing for minimum latency on LLM calls
  • You need semantic caching to reduce costs
  • Your primary concern is LLM infrastructure reliability

Can You Use Both?

Yes. They solve different problems and can be deployed together:

Agent → SatGate (budget enforcement) → Bifrost (LLM routing) → OpenAI/Anthropic/etc.

SatGate enforces economic controls. Bifrost optimizes the LLM layer. Different layers, complementary value.
