Why Switch from LLM Gateway?
Thinking about moving away from LLM Gateway? Here are the most common reasons teams make the switch — and what to look for in a replacement.
💰 Pricing doesn't match your usage

🔧 Missing features you need

🚀 Performance or reliability concerns
If LLM Gateway has been slow, unreliable, or has had breaking changes that disrupted your workflow, switching to a more stable alternative can save your team significant frustration and lost productivity.
🔒 Privacy or compliance requirements
Your data handling requirements may have changed — whether it's GDPR, SOC 2, HIPAA, or internal policies. Some alternatives offer self-hosting, on-premise deployment, or stricter data residency controls that LLM Gateway may not provide.
