Test the agent you shipped
Point Testzilla at your existing ElevenLabs agent ID — no rebuild, no migration.
Testing ElevenLabs
You built your agent on ElevenLabs Conversational AI. Testzilla is the testing layer you plug in beside it — vendor-neutral but vendor-interactive. It connects to your real ElevenLabs agent over a browser WebRTC session, the same path a visitor takes when they talk to it on your site.
