Multi-Agent Testing
Deploy up to 10 AI agents that explore your app simultaneously. Each agent thinks independently, clicks different paths, and finds bugs human testers miss.
Under the hood
How it works
Three phases, fully automated. From project drop to bug report in minutes.
Agent Deployment
When you drop a project, VibeQA spins up isolated browser sessions — one per agent. Each agent gets its own viewport, cookies, and session state. They don't interfere with each other.

Intelligent Exploration
Agents don't just click randomly. Each agent builds a map of your app as it explores. It prioritizes untested paths, form submissions, and state transitions. Think of it as 10 QA engineers who communicate about what they've already tested.
Parallel Bug Detection
As agents explore, they run 2,967 bug pattern checks in real-time. One agent might find a broken button while another discovers an XSS vulnerability on a different page — simultaneously.
Step by step
What each agent does
Every agent follows the same rigorous testing protocol. Here is the full sequence, from first page load to final report.
Scan the DOM
Each agent parses the full page DOM, identifying every interactive element — buttons, links, inputs, selects, textareas, and custom components that respond to clicks or keyboard events.
Capture visual state
A full-page screenshot is taken and stored as the baseline. This screenshot is later compared against post-interaction captures to detect visual regressions, layout shifts, and rendering artifacts.
Classify interactive elements
Elements are sorted into categories: navigation links, form inputs, action buttons, toggles, modals triggers, and dropdowns. Each category has its own testing strategy — forms get filled, buttons get clicked, links get followed.
Interact and observe
The agent clicks elements, hovers over tooltips, opens dropdowns, and observes the resulting state changes. It watches for DOM mutations, network requests, URL changes, and console output. If a click triggers a modal, the agent tests inside it before closing.
Fill forms intelligently
Forms receive three rounds of input: valid data first (to confirm the happy path works), then edge cases (empty strings, 256-character names, unicode, special characters), then attack payloads (XSS vectors, SQL injection patterns, path traversal strings).
Map the route tree
As agents navigate to new pages, they build a graph of your application's route structure. Internal links are followed. External links are noted but not followed. The agent tracks which routes have been tested and which remain unexplored, sharing this map with other agents.
Run diagnostics
On every page, the agent checks for console errors and warnings, failed network requests (4xx, 5xx), missing alt text and ARIA labels, color contrast violations (WCAG AA), broken images, and mixed content warnings.
Report findings
Each bug gets a severity (critical, warning, info), a human-readable description, the exact element selector, a screenshot of the issue, and a suggested fix. Reports are deduplicated across agents so you never see the same bug twice.
Configuration
Choose your scan depth
More agents means more coverage, but also more time. Pick the right balance for your workflow.
Small apps, single-page sites, quick sanity checks before a deploy. Good for when you just changed one component and want to make sure nothing broke.
Medium apps with 10-30 routes. Covers main flows, form submissions, and most edge cases. The sweet spot for daily development — fast enough to run often, thorough enough to catch real bugs.
Complex apps with many routes, role-based access, multi-step wizards, and nested modals. Use this before releases, after major refactors, or when onboarding a new codebase you don't fully trust yet.
How coverage is calculated: VibeQA discovers all reachable routes from your entry point, then tracks which routes and interactive elements each agent has tested. Coverage includes route visits, form interactions, button clicks, and state transitions. A route is only marked "covered" when all its interactive elements have been tested with both valid and invalid inputs.
Live output
Watch agents work in real time
VibeQA streams agent activity as it happens. Here is what a typical scan looks like with 7 agents running against a SaaS app.
Critical
Security flaws, data exposure, auth bypasses. Must fix before shipping.
Warning
Broken interactions, a11y violations, missing validation. Should fix soon.
Passed
Tested and working. Confirmed valid — no action needed.
Technical details
Built for real-world apps
Multi-agent testing handles the complexity that real applications throw at you.
Session isolation
Each agent runs in its own browser context with separate cookies, localStorage, sessionStorage, and IndexedDB. Agent 1 logging in as admin won't affect Agent 2's unauthenticated testing. This is real isolation, not just separate tabs.
Agent coordination
Agents share a route coverage map in real time. When Agent 1 finishes testing /dashboard, Agent 2 knows not to repeat it and moves to /settings instead. This avoids duplicate work and maximizes the surface area tested per minute.
Resource management
VibeQA monitors CPU and memory usage on your machine. If resources run low, it pauses lower-priority agents rather than letting your system slow down. On an M1 MacBook with 16GB RAM, 10 agents use roughly 2.5GB total.
Framework detection
Agents detect your framework automatically — Next.js, Nuxt, SvelteKit, Remix, Rails, Django, Laravel, Express, and static sites. Framework-specific checks are enabled: Next.js apps get App Router vs Pages Router testing, Nuxt apps get auto-import validation.
API endpoint testing
If an agent discovers API routes (through link tags, fetch calls, or sitemap parsing), it tests them separately: wrong HTTP methods, missing headers, malformed JSON bodies, oversized payloads, and authentication edge cases.
