Qontinui is an open-source software factory for your own codebase. A fleet of AI agents plans, implements, tests and lands changes in parallel, against a digital twin of your development process, so they answer their own questions instead of asking you.

Unlike screen scrapers or DOM parsers, UI Bridge understands your application's React component tree. It sees what your users see — and more.
Inspects component props, state, and hierarchy across any React app — Next.js, Tauri, React Native.
Works on websites, desktop apps, and mobile apps. One tool for all your React frontends.
Click, type, and interact with elements programmatically. Faster and more reliable than pixel-based approaches.
Model your application's states and transitions. Based on peer-reviewed research in model-based GUI automation.
Lightweight extension for element discovery and screenshots in external browser tabs.
AI agents use UI Bridge to verify their changes actually work — they see the real application, not just code.
Build, execute, and monitor AI development workflows from your browser
Bring your own API key. No subscriptions to third parties. No unauthorized access. Just direct, compliant integration with the providers you choose.
Claude Code CLI or API key. Use your subscription or pay-per-token.
Gemini CLI with OAuth or API key. Free tier available.
Open architecture. Adding new providers is straightforward.
Switch providers without changing your workflows. Your automations aren't locked to any single vendor.
Multi-phase AI sessions with setup, agentic, verification, and completion stages. Not just a chat interface.
Verification loops catch mistakes automatically. AI checks its own work before moving on.
Watches your application logs in real-time. Detects errors and triggers AI to fix them automatically.
AI sees your running application through deep React inspection. Verifies changes visually, not just syntactically.
AI builds knowledge across sessions. Findings, contexts, and patterns persist and compound over time.
Built-in Playwright and UI Bridge testing. AI writes and runs tests to verify its changes work.
You state intent and review outcomes. Everything in between is done by agents, and each step leaves a record the next agent can read.

One plan, from draft to shipped, every step recorded.

Agents ask the twin instead of asking you.

Blocked work waits on a condition, not on a person.

Many pull requests, landed in order.

Many sessions on many machines, without collisions.

Red CI is diagnosed and fixed by the agent itself.
The animations are illustrative: hand-authored runs, not recordings.
Based on peer-reviewed research published in Springer's Software and Systems Modeling journal (2025).
Published in Springer SoSyM — the first mathematically-proven approach to GUI automation that reduces complexity from exponential to polynomial growth.
