When your model vendor becomes your competitor,
how fast can you leave?

Every LLM through one API. Swap models live, no redeploy. Your data never stored. Leave whenever you want.

// the layer

One layer between you and every vendor.

From routing to drift detection, Verlon handles the plumbing so no provider decision can break your product.

Spend less, not more.

Verlon takes no cut of your provider bills. We route simple queries to cheap models, cap runaway costs, and surface spend surges before they sting. Your economics, not their pricing.

Catch problems before users do.

Drift, latency spikes, quality regressions, silent model changes. Surfaced automatically. No dashboards to build, no alerts to configure.

Swap models without changing code.

Every new model is just a config change. No rewrite, no rollout, no second-guessing. When a vendor deprecates, reprices, or turns on you, you’re one config change from gone.

Coming from LiteLLM, OpenRouter, or rolling your own?
Drop in with one config swap.

Migrate in minutes

// your data

Your data never stored.

Zero retention by default. Prompts and completions pass through; nothing is kept. Bring your own keys and your provider relationships stay yours, not ours.

If Verlon vanished tomorrow, your keys would still work. There is nothing of yours to export or beg for, because there is nothing of yours we hold.

// use cases

Everything outside your code.

Routing, cost, experiments, model swaps, agents, and observability, all configured from the dashboard or your IDE. Your code stays a few lines, and stays yours.

Experiment created. Watching summary-quality, 50/50 across gpt-4o and claude-sonnet-4. I’ll surface a winner after 1,000 requests.

Ask Claude Desktop or Cursor to set up routing, create experiments, swap models, debug live traffic. Never open a browser tab.

// what we believe

If you build on AI, you shouldn’t be at your vendor’s mercy._

Own what’s yours. Limit what your vendor gets. Keep quality and cost in your hands. And when you’re ready, run your own models.

No vendor should ever own you.
