AI users that test your app
Jina creates synthetic users that explore your app and catch issues like real humans. Prompts become self-healing tests. Functional testing on autopilot.
Backed and built by a team from
Build E2E tests from a single prompt
Prompt Jina to explore your app and set up a test case along with assertions.
- Use for regressions, feature launches, production monitoring
- No more writing or maintaining tests
- Engineering team ships quickly with confidence
Testing Instructions
Example: E-commerce Checkout
"Test the checkout flow for our e-commerce site. Verify a user can add items to cart, enter shipping details, and complete purchase."
AI-Generated Test Plan
Test Case: Product Search
#search-input to [data-testid="search-box"].Self-healing, minimal maintenance
Tests that adapt to shifting UI and don't break on minor changes.
- Adapts to visual or structural changes automatically
- Not tied to brittle DOM selectors
- Tests only fail when real user flows break
Automate your test runs
Run tests on a schedule, in CI/CD, or via API.
- Trigger tests as part of your pipeline
- Run on-demand through a REST API
- Schedule automated test runs
Test Case: Checkout Flow

Meet the Jina SDK — our vision-based browser agent
We built the Jina SDK — a state-of-the-art, open-source browser agent — and it's the engine running under Jina. Vision-first. No DOM. No brittle selectors. Just a model that sees your app the way a real user does.

Vision-first loop
Screenshot → model → action → repeat. The Jina SDK reads the page the way a human does, not through a fragile element tree.
Self-healing replay
Cache actions, replay without the model. When a page changes, the Jina SDK adapts automatically — no broken tests, no maintenance burden.
Streaming SDK
agent.stream() yields typed StreamEvent objects. Plug real-time agent progress directly into your UI or pipeline.
Any model, your stack
Works with Anthropic, Google, OpenAI, or any OpenAI-compatible endpoint. No vendor lock-in.
Bring agentic QA and browser automation to your own stack. The Jina SDK is open-source and ready to embed.
Frequently asked questions
Everything you need to know about Jina.
Jina is an autonomous AI QA engineer. You describe what to test in plain English, and Jina generates, runs, and maintains end-to-end tests for your web application — no code required.
Simply provide a prompt describing a user flow (e.g. "test the checkout process"). Jina explores your app, maps out the steps, generates assertions, and produces a fully executable test plan automatically.
No. Jina is designed for teams of all technical levels. Product managers, QA analysts, and engineers can all create tests using natural language prompts.
When your UI changes — a button moves, a selector gets renamed — Jina detects the change and automatically updates the test to match the new state. Tests only fail when a real user flow breaks, not because of minor UI updates.
Jina provides a REST API and native integrations for popular CI/CD pipelines. You can trigger test runs on every deployment, on a schedule, or on demand via webhook.
Jina SRE is our proactive monitoring product. While Jina QA helps you build and run tests, Jina SRE continuously watches your live application, detects anomalies, and attempts to fix issues before your users notice them. Learn more at sre.usejina.com.
Yes. Jina operates with strict least-privilege permissions and your application data never leaves your infrastructure. We also support private deployment in your own cloud environment for complete control.
Cypress and Playwright require engineers to write and maintain code for every test. Jina generates and maintains tests automatically from plain-English prompts, self-heals when the UI changes, and requires zero ongoing test maintenance.
