Proceed to cart button isn't clickable — users can't reach checkout
FIX PR
Pie drafted the fix
pie BOT opened just now
fix: reset loading state so Proceed to cart stays clickable
ROOT CAUSE
handleClick() sets loading to true but never resets it — button stays disabled after the first click.
FIX APPLIED

The product broke anyway.

Discovered by a customer. 4 hours after deploy. CI was green.

PR #412 — Refactor payment reduce logic

Order total renders $0.00. Discount logic skips the merge after the reduce function changed.

3 approvals all checks pass merged to main

These are the bugs that pass every code review tool on the market. They don't live in the diff. They live in the running product. Pie catches them because Pie actually uses your product, the same way your customers do.

What teams are saying

Real results from real teams

An iOS-only crash that happened after three specific steps? Manual testing never would have caught that. Pie found it on the first scan.

— Mobile Test Lead, Consumer Tech Startup

We used to find regressions a week after they shipped. Now we catch them before the PR even merges. It changed how we think about testing.

— Engineering Manager, Series A Fintech

The autofix feature is honestly what sold us. Finding bugs is one thing. Getting a PR with the fix already written? That's next level.

Frequently Asked Questions

Code review tools analyze your code. Pie tests your running product. CodeRabbit can tell you if your checkout function looks correct. Pie actually clicks "Buy Now" on staging and confirms the payment goes through. They read diffs. We use the app.

You authorize Pie on GitHub, pick a repo, and paste your staging URL. That's it. No SDK, no test scripts, no config files. Pie figures out your user flows automatically by exploring your app.

Pie reads your commit diffs to understand what changed, then maps that to the user flows it discovered when it first explored your app. If your payment form changed, Pie tests checkout. If you touched the nav, it tests cross-page navigation. It's not random.

Yes. Pie tests iOS and Android apps in simulators, not just web. Same 2-click setup. Same autofix PRs. Mobile-specific bugs like gesture failures, deep link issues, and in-app purchase flows are all covered.

Pie only reports bugs it can reproduce. Every finding includes a step-by-step recording of how to trigger it. If Pie reports it, it's real. No flaky tests, no "works on my machine" arguments.

When Pie finds a bug, it doesn't just log it. It traces the issue back to the source code, identifies the likely root cause, and opens a PR with a suggested fix. You review and merge, or reject if it's wrong. Most fixes merge without changes.

Pie runs on secure, isolated infrastructure. Your code never leaves your repo, we only read the diffs. Your staging environment is accessed the same way your CI does. We're SOC 2 compliant. Reach out and we'll share the documentation.

You can run both, or let Pie take over entirely. Pie can analyze your existing test cases and rebuild them using AI, with zero ongoing maintenance. Most teams that migrate see better coverage and stop dealing with flaky tests. We'll help with the transition.

Your first scan is free, no credit card required. After that, pricing scales with your usage. We offer packages for teams of all sizes. Reach out and we'll put together a quote.

Not currently. Pie runs as a managed service. For teams with strict data residency requirements, reach out and we'll discuss options.
