We Battle-Test
Your Claude App

You built something with Claude. We throw everything at it — edge cases, adversarial prompts, jailbreak attempts, hallucination traps — and tell you exactly where it breaks before your users do.

Four steps from submission to signed-off.

01
Submit Your App
Share your Claude integration — API endpoint, system prompt, use case. We sign an NDA before you send anything.
02
We Build the Bots
Our Claude-powered test bots are configured specifically for your app — probing its exact use case, audience, and risk surface.
03
Full Attack Run
100+ test scenarios: edge cases, prompt injections, adversarial inputs, persona jailbreaks, hallucination traps, context attacks.
04
Detailed Report
You get a full PDF report — every failure, severity rating, and exact fix recommendation. No jargon, just results.
What We Test

Testing Services

Every Claude app is different. We customize tests to your exact use case.

🛡️
Safety & Guardrails
Jailbreak attempts, prompt injection, persona manipulation, policy bypass — we find every hole before bad actors do.
Security
🎯
Accuracy & Hallucination
We feed your app factual traps and ambiguous inputs to measure how often it fabricates, confabulates, or confidently gets it wrong.
Accuracy
⚡
Edge Case Stress Test
Malformed inputs, extreme lengths, language switching, contradictory context — everything real users will eventually try.
Reliability
🔁
Conversation Flow
Multi-turn stress testing — context drift, memory leaks, instruction overrides buried in long conversations.
UX
📊
Performance Benchmarking
Response quality scoring across hundreds of runs. Consistency, latency variance, and grade distribution charted and reported.
Performance
📋
Compliance Check
Does your app handle PII correctly? Does it refuse appropriately? We run your use case against Anthropic's usage policies.
Compliance

Run 30 Tests Right Now

Paste your system prompt, endpoint, or API key — we run 30 adversarial tests and email you a full PDF report in about 5 minutes.

Choose how to connect your app
We'll run your prompt against Claude and test how it responds to adversarial inputs. Your prompt is not stored beyond the test run.
We'll POST {"message": "..."} to your endpoint. Response should be JSON with a response, message, or text field.
Your key is used only for this test run and never stored. We run tests using your key so results reflect your actual production cost and quota.
