Customer stories
How teams use Killbug.
Protect critical journeys, catch regressions, and debug with evidence.
"We recorded our invite, billing, and role-change flows in an afternoon. The first scheduled run caught a permissions regression before our release review."
Maya Chen
Product Lead, B2B SaaS
"Our support team kept seeing checkout edge cases before engineering did. Killbug gives us the recording and failed step, so triage starts with evidence."
Jordan Lee
Engineering Manager, Marketplace
"We are still changing onboarding every week. Being able to add coverage without writing a new test suite has made QA part of the shipping rhythm."
Nina Patel
Founder, Workflow Automation
"The regressions that hurt us are usually account setup, permissions, and reports. Those are exactly the flows we now run before every weekly release."
Alex Ramirez
Head of Product, Vertical SaaS
"Our Monday smoke check used to be a spreadsheet and a screen share. Now we review failed runs with recordings and assign the real fixes faster."
Aisha Brown
QA Lead, Developer Tools
FAQ
What teams want to know before they start testing with Killbug.
What is Kibi?
Kibi is Killbug's AI QA agent. Tell Kibi what you want to test, and it can explore the product flow, create test case drafts, run them in a real browser, and turn failures into actionable issues.
How does Kibi turn a goal into test cases?
Describe the journey or product area you want to cover in plain language. Kibi explores the flow and proposes useful test case drafts for you to review before they become repeatable coverage.
What happens when Kibi runs a test?
Kibi opens your product in a real browser, follows the selected test cases against the visible interface, and records the result and supporting evidence for each run.
Can Kibi test logged-in workflows?
Yes. Add safe test credentials and account instructions at the project level, then assign the right credential to authenticated test cases without repeating secrets in every flow.
What do I get when a test fails?
The failed step stays connected to the run details, browser recording, screenshots, and AI-generated summary. Your team can review the evidence and turn an actionable regression into an issue.
Can Killbug run checks automatically?
Yes. Group test cases into a test plan and run it manually, on a recurring schedule, or from a deployment webhook. Each run stays in the same history for review.
Does Kibi replace Playwright, Cypress, or manual QA?
No. Kibi adds fast, repeatable coverage for product-facing workflows without requiring every workflow owner to maintain scripts. Coded tests and human judgment still play important roles in a complete QA process.
