Why Blastoff
Every other eval tool makes you write code
Braintrust, Langfuse, and DeepEval all require you to install an SDK, write a test runner, and host the infrastructure yourself. Blastoff handles 100% of execution — you just paste a URL.

Prompt Injection Security Scan
Fire 165 adversarial prompts — DAN jailbreaks, base64-encoded instructions, OS command injections, persona manipulations, multi-language attacks, and more — directly at your agent. Our LLM judge scores each response as DEFLECTED or EXPLOITED.
No setup required — runs against your existing endpoint configuration.
GitHub CI Integration
Connect your repo and block pull requests automatically when eval scores drop. Ship with confidence.
Live Results
Watch row-by-row evaluation progress in real-time. Each response is scored and explained as it comes in.
No API Key? No Problem
Use our built-in Blastoff judge with zero setup. Or bring your own Anthropic or OpenAI key — your choice, your cost.
Latency Tracking
See avg and p95 endpoint latency across your dataset, plus per-row timing on every result. Catch slow queries before they hit production.
Share & Re-run
Share a public read-only results link with your team. Re-run only the failed rows — no need to retest what's already passing.
