Capture the exact state
Use Full Page, Responsive, Visible Screen or Select Area to preserve the UI state where the issue appears.
Developer verification focus: This page focuses on frontend implementation evidence and fix verification. For dedicated viewport capture and breakpoint testing, use Responsive Screenshots.

Screenshot tool for developersCapture the UI state.
Capture the UI state.
Verify the frontend fix.
Capture helps frontend and web developers document the visual side of implementation work without switching between a screenshot app, image editor and report tool. Preserve the exact UI state, annotate the affected component, compare the fix and export clear evidence.

Built for visual implementation work
From “something looks wrong” to evidence a developer can act on.
Capture is designed for the visual side of frontend debugging: layout shifts, spacing mistakes, broken responsive states, missing assets, overlapping components, typography differences, inconsistent UI and client-reported presentation issues.
Test responsive breakpoints
Capture Desktop, Laptop, Tablet, Mobile or custom viewport sizes so actual responsive CSS can react before capture.
Annotate precisely
Point to the affected component with arrows, boxes, text, highlights, pen marks or numbered callouts.
Preserve context
Store URL, page title, date/time, viewport dimensions, browser information, DPR and capture mode with the screenshot.
Compare the fix
Use Reveal, Side-by-Side and Differences to review what actually changed between two captured states.
Export a clean handoff
Copy the screenshot immediately or turn multiple annotated captures into a structured report or professional PDF.
Developer workflow
Capture. Explain. Fix. Verify.
A short visual loop for frontend bugs and implementation review.
Reproduce
Open the broken page or responsive state and capture exactly where the visual issue occurs.
Explain
Add concise arrows, boxes, labels, callouts and priority so the issue is easy to understand.
Fix
Use the screenshot, URL and viewport context as implementation evidence while correcting the UI.
Verify
Capture the updated state and compare it against the earlier screenshot before closing the issue.
Frontend screenshot tool
Useful when the problem is visual, not textual.
Many frontend issues are hard to explain in a ticket. “Card alignment looks off on tablet” or “the header overlaps the CTA” forces the developer to reproduce the exact state before they can even see the problem. A screenshot with the relevant viewport and annotation shortens that loop.
Responsive implementation checks
Capture at different viewport widths to inspect navigation wrapping, grid collapse, text overflow, form layout, CTA placement and other breakpoint-specific behavior.
Design implementation review
Designers and developers can use the same annotated screenshot to discuss spacing, alignment, hierarchy and visual consistency without writing long paragraphs.
Visual regression review
Verify what changed after the code changed.
Capture supports manual visual comparison for cases where a screenshot is the fastest way to review a UI fix. Reveal Slider helps inspect alignment, Side-by-Side gives context, and Differences highlights meaningful changed regions while ignoring small rendering noise.
Before and after bug fixes
Keep the original capture as Before and the corrected state as After. Export the comparison when a stakeholder, QA reviewer or client needs evidence that the requested visual change was completed.
Not an automated CI platform
Capture currently focuses on browser-based manual visual evidence. It does not claim to replace Playwright, Cypress, automated screenshot regression pipelines, console logging or network tracing.
Developer privacy
Keep staging screens, admin pages and client UI on your computer.
Development screenshots can include private dashboards, internal tools, staging environments, customer information or unreleased product UI. Capture is designed so normal screenshot capture, editing, comparison and local export do not require uploading the screenshot image to RATdeck.
Account and subscription communication is separate from screenshot-image processing.
✓ Full-page stitching happens locally
✓ Annotation and comparison happen locally
✓ Blur or pixelate sensitive details before sharing
✓ PDF/report generation is designed for local processing
Practical checklist
Make visual bug evidence easy to reproduce.
Screenshots help explain a defect, but they do not replace reproduction steps, browser details or logs. Include those details in your issue tracker alongside the image.
- Keep the test state comparable. Use the same viewport, page state and content before and after a fix.
- Annotate the expected result. Mark the affected element and describe the behavior that should change.
- Use differences as a review aid. Pixel differences can include fonts, animations and dynamic content. Inspect them before classifying a change as a regression.

Developer screenshot FAQ
Common questions from frontend and web teams.
What is a good screenshot tool for frontend developers?+
A useful frontend screenshot tool should capture the exact UI state, support responsive viewport checks, allow precise annotation, retain page and viewport context, and help verify visual fixes. Capture combines those workflows inside Chrome.
Can Capture help document responsive layout bugs?+
Yes. Capture supports responsive viewport presets and custom viewport sizes. The page is rendered at the requested viewport before capture so CSS media queries can respond instead of simply scaling a desktop screenshot.
Can I compare a bug before and after the fix?+
Yes. Use Reveal Slider, Side-by-Side or Differences. Differences includes sensitivity control, changed-region detection and an approximate percentage changed.
Does Capture automatically collect console logs or failed network requests?+
No. Capture currently focuses on visual screenshot evidence, metadata, annotations, comparison and reporting. It does not currently claim automatic console or network capture.
Can I add browser and viewport information to a report?+
Yes. Capture can store URL, page title, date/time, viewport dimensions, browser information, device pixel ratio and capture mode, and metadata can optionally appear in reports and presentations.
Do screenshots have to be uploaded to a server?+
No for normal capture, editing, comparison and local export workflows. Those screenshot operations are designed to happen on the user's computer. Account and subscription communication is separate.
Capture by RATdeck
Less explaining.
More useful visual evidence.
Capture UI issues, responsive states and visual changes directly in Chrome, then hand off screenshots developers can act on.
