Verification Belongs Inside the Dev Loop.
Not After It.
AI is making developers 3x faster. Testing just became the bottleneck. Karate Agent is the AI-native verification platform that keeps pace — from exploratory testing to CI/CD, on your infrastructure.
100% Self-Hosted • Bring Your Own LLM • Java 21 + Docker • Enterprise Ready
The Speed Problem — Solved
LLM-driven browser automation is powerful but slow. Flows fix this.
Guidewire PolicyCenter
12-step Personal Auto submission — login through quote — each step developed as an independent flow via Interactive mode, composed into a single orchestrator.
Flows execute at native JavaScript speed — no LLM tokens consumed. The LLM is only invoked for recovery when a step fails.
Why Karate Agent
Self-Hosted, Air-Gap Ready
Your data never leaves your network. Session transcripts, screenshots, and recordings stay on your file system. Suitable for financial services, healthcare, and government.
Bring Your Own LLM
Run with Claude, GPT, Gemma, Llama, or any local model via Ollama. Zero cloud dependency. No vendor lock-in. Use whatever model your organization has approved.
Token-Efficient by Design
Structured JSON responses — not DOM dumps. look() diffing reduces repeated page scans by 72x. One JS code block batches multiple actions in a single HTTP request.
Display-Text Locators
{button}Submit uses visible text, not CSS/XPath. When the app is refactored and element IDs change, display-text locators keep working.
MCP Server Built In
Single karate_eval tool via Model Context Protocol. Compatible with Claude Code, VS Code Copilot, and any MCP-compliant client. No sidecar, no Node.js.
Session Video Recording
Opt-in H.264 recording at 8fps. Compliance teams audit exactly what the agent did. QA reviews failures without reproducing them.
Start Free, Scale Gradually
Most teams stabilize at Stage 3: 90%+ scripted (free), LLM handles edge cases.
Interactive
Developer drives browser via curl or Claude Code. Discovers locators, explores the app.
Scripted Flows
Reusable .js flow files execute via Flow.run(). Deterministic, repeatable, no LLM.
Autonomous + Flows
Scripted flows first. LLM invoked only when a step fails — 2-4 recovery iterations.
Fully Autonomous
LLM drives the entire workflow. Reserve for exploratory testing or new workflows.
How It Works
From exploration to automation in three steps.
Explore Interactively
Your LLM coding agent drives a real browser via curl or MCP. Discover locators, test interactions, build understanding.
Create & Test Flows
Codify working patterns as reusable .js flow files. Execute at native speed — no LLM tokens consumed.
Run Autonomously
Submit jobs via dashboard or API. Flows run fast, LLM handles unknowns. Review reports, fix flows, repeat.
Who It's For
Solo Developer
Run the agent server locally. Test your app on localhost before you commit. Verify UI changes as part of your dev loop — the same agent that writes your code can test it. Personal automation for repetitive browser tasks.
Interactive User
Connect Claude Code, Cursor, or any LLM agent to a live browser session. Explore apps, discover locators, build and debug flows interactively. Develop automation step-by-step with instant feedback.
QA & Acceptance
Submit test jobs via dashboard or CI pipeline. Run scripted flows with AI recovery. Review reports, watch recordings, manage deviations. Shared team server with concurrent sessions.
Business Stakeholder
Watch session recordings to see exactly what was tested. Review reports on the shared dashboard — no technical setup required. Understand test coverage without needing access to code or infrastructure.
