About VoiceGremlin
VoiceGremlin is a testing platform for AI voice agents that runs automated end-to-end tests via real phone calls.
Developers and QA teams use VoiceGremlin to test AI voice agents in production environments. It suits engineering teams building or maintaining phone-based AI agents who need to verify their agents work correctly before customers encounter problems.
- Real phone call testing via REST API
- LLM-based test case evaluation and pass/fail judgment
- Complete call transcripts in failure reports
- Plain English test descriptions without scripted paths
Good to know: Offers 100 free minutes with no credit card required, and integrates into CI/CD pipelines via API.
Key features
- Real carrier line calls: Tests run on actual phone infrastructure, covering SIP integration, speech-to-text, text-to-speech, and agent behavior.
- LLM-based judging: An AI evaluates agent responses against test goals using inference rather than keyword matching or regex patterns.
- Quick API integration: Implementation requires just two API calls: one to start a test, one to retrieve results.
