The governance tunnel
Control exactly what leaves your network.
Spendplane captures the request, applies policy, picks the cheapest viable lane, and shows the live decision instead of hiding it behind the agent.
The Scrubbing Layer
Before any token hits an LLM, your request passes through Spendplane's proxy. We automatically scan for sensitive PII using specialized red-team models, strip redundant data, and apply budget guardrails.
- Automatic PII redaction
- Context compression
- Budget enforcement

$0.04/reqIntelligent Routing
Not every prompt needs GPT-4. Spendplane dynamically routes your payload to the cheapest capable model based on task complexity, slashing your cloud bill without sacrificing quality.
- Model cascading capabilities
- Cost-threshold fallbacks
- Latency-aware selection
Trace, Restore & Deliver
Watch the full lifecycle in real-time. Once the LLM responds with scrubbed tokens, Spendplane securely re-maps them to their original values and delivers a complete, private response to your app - zero PII ever leaked.
- Full payload introspection
- Secure PII re-insertion on return
- Cost attribution per request
- Zero-leak delivery guarantee

The tech behind the Tunnel.
Everything you need to know about security, latency, and how we protect your AI supply chain.
Does the Governance Tunnel add latency to AI requests?
Minimal. Our globally distributed proxy layer adds less than 15ms of overhead while performing real-time PII scrubbing and budget checks. In many cases, our intelligent routing to lower-latency regions actually speeds up your overall response time.
How does the 'Vibe to Production' 3-step integration work?
It's simple: (1) Export your code from tools like Bolt or v0, (2) Point your OpenAI/Anthropic BASE_URL to api.spendplane.com, and (3) Add your Spendplane API key. No code changes required to get enterprise-grade security.
Is my data stored or used for training?
Never. Spendplane is a pass-through governance layer. We scrub PII in real-time and deliver the request to the provider. We do not store request bodies or use your data for model training. We only store metadata for your audit logs.
Can I enforce hard budget limits per project?
Yes. You can set granular daily, weekly, or monthly credits for every API key. If a limit is hit, the proxy gracefully pauses traffic, preventing runaway costs from loops or high-usage spikes.
Does it work with private GPUs and local hardware?
Absolutely. Spendplane's hybrid routing can detect your local hardware (via our CLI/extension) and route 'vibe' requests there first, only bursting to the cloud when your local resources are saturated.
What is the difference between Starter and Enterprise?
Starter is designed for individuals and small teams needing live routing and guardrails. Enterprise is a custom review path for teams that need tighter governance, deployment planning, regional controls, or private infrastructure options.
