Compare autonomous QA to every approach you've tried. See why teams ship faster without writing tests.
Most testing tools measure success by test count. 500 tests passing feels productive until you realize you're still shipping bugs.
Pie measures what actually matters: bugs found before your users find them. Every issue gets human verification before reaching your team, so you fix real problems instead of investigating false positives.
Watch Pie find real bugs in your app during a live demo. No slides.

Not features. Outcomes. Here's what each approach delivers for your team.
| What you get | Pie | Selenium | Cypress | Playwright | Other AI Testing Tools |
|---|---|---|---|---|---|
| Time to first coverage | Day one | Weeks to months | Weeks to months | Weeks to months | Weeks to months |
| Tests that don't break | Vision-based | Break on UI changes | Good DX, auto-waiting | Partial resilience | Smart locators |
| Maintenance burden | Zero | High (manual) | Medium | Medium | Reduced |
| Coverage without effort | AI discovers paths | You define it | You define it | Codegen recording helps | You define it |
| Engineering resources needed | None | SDETs required | JS developers | Developers | QA team |
| False positive rate | Human verified | Common | Moderate | Moderate | Varies |
Explore Pie's sandbox with a sample app. No signup needed.
Traditional test automation is an investment that pays off in months. You hire SDETs, set up infrastructure, write tests, debug flaky selectors, and eventually get coverage.
Pie delivers 80% coverage from your first session. Point it at your app and watch it explore. The same day you sign up, you're finding bugs.
"The way that Pie set up has allowed Fi to work alongside our development process. We didn't have to change how we did things."

Each approach has trade-offs. The right choice depends on your team size, engineering capacity, and how fast you need to ship.
Maximum flexibility and zero licensing cost make open source attractive for teams with strong engineering resources. Selenium has the largest community and supports any language. Cypress offers better developer experience with automatic waiting and time-travel debugging. Playwright provides cross-browser support with a modern API.
AI-assisted platforms reduce the engineering burden with smarter element location and self-healing capabilities. Testim uses ML for stable locators. mabl offers agentic test creation and auto-healing. Functionize claims 99.97% element recognition accuracy. All reduce maintenance compared to pure open source.
Services like QA Wolf provide a human team that builds and maintains tests for you using open source tools like Playwright. They promise 80% coverage in about four months with 24-hour maintenance and a zero-flake guarantee. You own the code without vendor lock-in.
Pie takes a fundamentally different approach. Instead of recording or scripting tests, AI agents explore your application like real users would, discovering critical paths and edge cases autonomously. Vision-based recognition means no selectors to break. Every bug gets reviewed by a human QA professional before reaching your team.
Your code never leaves your environment. Pie connects to your staging or production URLs and tests from the outside, just like a real user. No SDKs to install, no agents in your infrastructure, no code access required.
Pie tests your app like a user would. No agents, no SDKs, no code access.
Fi, a pet safety company building AI-powered GPS collars, switched from a 12-person manual QA team to Pie.
"The time between having a release candidate ready and being fully tested has gone from two to three days to a few hours."
Philip Hubert, Director of Mobile EngineeringFrom 12+ engineers dedicated to testing down to a single QA engineer managing Pie. The team now focuses on building features.

Pie agents explore your application like real users, identifying critical paths and edge cases without being told where to look. Coverage grows as your product evolves.
No selectors, no locators, no XPaths. Pie sees your UI the way humans do: visual context, semantic meaning, and structural patterns. UI changes no longer break tests.
Every bug Pie finds gets reviewed by a QA professional before reaching your team. No noise, no false positives, no wasted engineering time investigating non-issues.
Questions we hear from teams evaluating test automation approaches.
Pie complements rather than replaces existing tests. Many teams keep their unit and component tests while using Pie for end-to-end coverage. Over time, some teams phase out their E2E scripts as Pie's coverage expands, reducing maintenance burden.
AI platforms like Testim and mabl use AI to help you create and maintain tests faster, but you still define what to test. Pie's agents autonomously discover what needs testing. It's the difference between AI assistance and AI autonomy.
Pie focuses on end-to-end testing where users interact with your complete application. Unit and component testing remain valuable for isolated logic validation. Most teams use Pie alongside their existing unit test suite.
Pie uses three recognition layers: visual appearance, semantic meaning, and structural context. This multi-layer approach handles dynamic content, A/B tests, and UI variations that break traditional selector-based tests. Learn more about self-healing.

Pie typically achieves 80% coverage within the first day of setup. The Fi team went from release validation taking 2-3 days to just a few hours after implementation.
