THE OLD WAY

Feeling locked in?

You're not alone

Feeling locked in?

You're not alone

Many AI platforms build their business around keeping you dependent on one provider. Rate hikes, outages, and model gaps aren't bugs — they're features of a locked ecosystem.

There's a better way.

Many AI platforms build their business around keeping you dependent on one provider. Rate hikes, outages, and model gaps aren't bugs — they're features of a locked ecosystem.

There's a better way.

Surprise pricing hikes

When your only provider changes rates, you have no leverage and no alternatives. Your costs spike overnight.

No fallback when models are slow

Rate limits and outages hit your users directly when you're tied to a single provider with no backup plan.

Vendor lock-in by design

Proprietary APIs are engineered to make switching painful — even when you know you should.

Always the wrong model for the job

Sometimes Claude is smarter. Sometimes Gemini is faster. With one provider, you can never pick the best tool.
