Async Video Code Reviews — Ship Faster Without the Meetings
Record your screen, walk through pull requests and diffs, and share a timestamped video link your team can watch on their own schedule. Cap makes async code reviews faster, clearer, and calendar-free.
Everything You Need for Async Video Code Reviews
Cap gives engineering teams a faster way to give and receive code feedback — no scheduled calls, no back-and-forth in PR comments
Record Any PR or Diff Walkthrough
Open your IDE, point your camera at the diff, and talk through your feedback in real time. Cap records your screen and webcam simultaneously so reviewers see exactly what you see — cursor movements, code highlights, and all. No more writing long PR comments that take longer to read than a 90-second video.
Instant Shareable Link — No Upload Wait
Stop recording and Cap generates a shareable link immediately. Paste it into your PR comment, Slack message, or Linear ticket. Reviewers click the link and the video plays in their browser — no app install, no login required on their end.
Timestamped Comments and Threads
Reviewers can leave comments at specific timestamps in the video, turning async code review recordings into threaded discussions. Replies, reactions, and resolved threads keep feedback organized without flooding your PR with comments.
4K Recording at 60fps for Sharp Code Legibility
Syntax highlighting, font rendering, and editor themes are captured at full fidelity. Cap records at up to 4K resolution and 60fps so reviewers can pause the video and read every line of code clearly — even on smaller screens.
Studio Mode for Architecture Walkthroughs
For longer code reviews — RFC feedback, architecture diagrams, or onboarding walkthroughs — Studio Mode records screen and webcam as separate tracks with no time limits. Edit your recording before sharing if you want to trim the intro or add chapter markers.
AI-Generated Captions for Accessibility
Cap auto-generates captions for every recording using AI transcription. Team members who prefer to read, are in a noisy environment, or speak English as a second language can follow along without audio. Captions are searchable so reviewers can jump to the part they need.
Password Protection and Expiry Links
For sensitive code reviews involving proprietary algorithms, security patches, or unreleased features, add a password to your recording or set an expiry date. Only intended recipients can access the video.
Works With GitHub, GitLab, Linear, and Jira
Cap links are just URLs — paste them anywhere your team already works. Drop a Cap link in your GitHub PR description, GitLab MR comment, Linear issue, or Jira ticket. No integration setup, no webhooks, no OAuth.

Why Engineering Teams Choose Cap for Code Reviews
Async video code reviews cut context-switching and make feedback more precise — here's how Cap compares
Cap vs Loom for Code Reviews
Loom is a capable async video tool but limits recording length and quality on its free plan, and stores all video on Loom's servers with no self-hosting option. Cap records at 4K with no recording-length limits in Studio Mode and supports self-hosted S3 storage for teams with data residency requirements. Cap is also MIT-licensed and fully open source.
Cap vs Written PR Comments
Written PR comments are slow to compose and easy to misread. A 2-minute Cap recording replaces a wall of inline comments — reviewers see the exact context you're referring to, hear your tone, and understand intent without the ambiguity of text. Video feedback also reduces the back-and-forth clarification round trips that slow code review cycles.
Cap vs Zoom or Google Meet for Code Reviews
Synchronous video calls require scheduling across time zones, force reviewers to be present at a specific time, and produce recordings that aren't easily linked, timestamped, or commented on. Cap gives you the clarity of a face-to-face walkthrough with the flexibility of async — reviewers watch when it suits them and leave timestamped comments.
Cap for Distributed Engineering Teams
Teams spread across multiple time zones struggle to schedule live code reviews. Cap lets the author record a walkthrough asynchronously and share a link in the PR. Reviewers in any time zone watch the video at their own pace, leave timestamped comments, and the cycle continues without anyone waiting on a meeting invite. See how distributed teams use Cap.
Two Recording Modes for Every Code Review
Choose the right recording workflow for the type of feedback you're giving
Instant Mode
Perfect for quick PR reviews, bug reports, and daily code feedback. Record, stop, and share a link within seconds. Ideal when you want to give fast, focused feedback on a specific diff without spending more than a few minutes.
Studio Mode
Built for thorough architecture reviews, RFC walkthroughs, and technical onboarding sessions. No time limits — record as long as your review requires. Separate screen and webcam tracks give you more control over the final recording.

How Engineering Teams Use Async Video Code Reviews
From quick PR walkthroughs to deep architecture reviews, Cap fits into every stage of the engineering feedback cycle
Pull Request Walkthroughs
Record a 2-minute walkthrough of your PR before requesting review. Explain the approach, highlight the tricky parts, and flag anything the diff doesn't make obvious. Reviewers arrive informed and spend their review time on decisions, not re-reading context.
Reviewer Feedback on Complex Diffs
Instead of writing inline comments for every concern in a large PR, record a video walkthrough of your feedback. Point your cursor at the specific lines, explain the issue verbally, and suggest alternatives in context. Authors watch the recording and address feedback in bulk.
Architecture and RFC Reviews
Walk through architecture diagrams, ADRs, and RFC documents on screen while explaining your thinking. Stakeholders and tech leads can watch at their own pace, pause to think, and leave timestamped questions. No meeting required to gather input on design decisions.
Security and Compliance Review Walkthroughs
Security engineers can record walkthroughs of vulnerability findings, showing exactly which code paths are affected and why. Developers watch the video and understand the full context of a finding without a call. Password-protected recordings keep sensitive findings private.
Junior Developer Mentoring and Code Feedback
Senior engineers record detailed code review videos that junior developers can watch multiple times, pause at any point, and reference later. Written feedback is easy to skip; video feedback with cursor movement and explanation sticks. See how Cap supports developer onboarding.
Cross-Team API and Integration Reviews
When backend teams review frontend API usage or platform teams review integration patterns, async video bridges the gap between domain contexts. Record a walkthrough of the integration code, explain the expected contract, and share with the other team without interrupting their sprint.
