“It did not work” is not enough for engineering. A screenshot or screen recording usually misses browser version, viewport, prior actions, page state, console errors, failed requests, and the exact moment the issue appeared.
Capture
BugTwin
Replay the exact bug.BugTwin packages the exact context around a failure: page state, user actions, URL changes, viewport, console errors, failed network requests, timestamps, and reproduction steps. Developers receive evidence they can replay instead of an incomplete screenshot.
01
Why this capability exists
From friction to a clear outcome
BugTwin captures the failure as a synchronized evidence timeline. Developers can inspect the environment, see what changed, and follow the same reproduction path without asking the reporter to recreate the story from memory.
02
Real-world scenario
Capture a checkout button that fails only on mobile
- 1
Start BugTwin before reproducing the checkout issue
- 2
Complete the same cart and payment path once
- 3
Capture the failing click with console and network context
- 4
Review and redact unrelated customer information
- 5
Send engineering one replayable BugTwin link
03
End-to-end workflow
How BugTwin works
- 01
Start a bug capture and reproduce the issue once.
- 02
TabTwin correlates actions, snapshots, console output, and network failures on a timeline.
- 03
Share a BugTwin link so engineering can inspect the context and replay the reproduction path.
04
What is included
Core capabilities
Action timeline
Records clicks, inputs, scroll, navigation, and timing in the order they occurred.
Environment capture
Includes URL, browser, viewport, route, and relevant session metadata.
DOM snapshots
Preserves the useful page state before, during, and after the failure.
Console evidence
Correlates warnings and runtime errors with the action that triggered them.
Network failures
Surfaces failed requests and response context beside the user journey.
Generated repro steps
Turns the raw session into a clean, human-readable reproduction guide.
05
Where it wins
Best use cases
- ✓Checkout and payment failures
- ✓Intermittent frontend bugs
- ✓Browser or viewport-specific regressions
06
What the user gets
Expected outputs
- →Replayable bug timeline
- →Auto-generated reproduction steps
- →Environment, console, and network evidence
What changes for the team
- ↗Shorten the gap between bug report and reproducible issue
- ↗Give QA and engineering the same source of truth
- ↗Preserve intermittent failures that are hard to reproduce twice
Safe by design
- ✓Reporters can preview and redact the capture before sharing
- ✓Sensitive inputs and excluded fields are removed at the source
- ✓Access can be limited with an expiring private link
BugTwin preserves executable browser context, not just pixels—so the report explains both what the user saw and what the browser did.
One shared technical foundation
Powered by the Browser Session Engine.
BugTwin consumes the same structured DOM events, timeline, context, snapshots, and safe execution primitives as the rest of TabTwin—without requiring another extension.
