Developer Documentation Videos — Record API Demos and SDK Walkthroughs
Create professional developer documentation videos with screen recording. Record API demos, SDK walkthroughs, CLI tutorials, and changelog videos in seconds. Cap is free, open-source, and built for developers who ship documentation alongside code.
Everything You Need to Create Developer Documentation Videos
Cap gives developers a fast, high-quality way to record and share technical documentation — without a video team or complex setup
Record API Demos and SDK Walkthroughs
Open your terminal, IDE, or browser and start recording. Cap captures your screen and webcam simultaneously so viewers see exactly what you see — code execution, API responses, SDK method calls, and all. Narrate as you go and produce a complete API demo in minutes, not days.
4K Resolution for Readable Code and Terminal Output
Cap records at up to 4K resolution at 60fps, which means syntax highlighting, terminal text, JSON responses, and font rendering are captured at full fidelity. Developers watching your documentation can pause and read every line of code clearly — even dense stack traces and config files.
Instant Shareable Link — Embed in Docs Anywhere
Stop recording and Cap generates a shareable link immediately. Paste it into your README, Notion doc, Confluence page, GitHub wiki, or Docusaurus site. Viewers watch the video in their browser without installing anything. Use the embed code to inline videos directly in documentation pages.
AI-Generated Transcripts for Documentation Search
Cap auto-generates accurate captions and transcripts for every recording using AI transcription. Developers who prefer to read, are in loud environments, or need searchable content get a full text version alongside the video. Transcripts make your documentation more accessible and easier to index.
Studio Mode for Long-Form Technical Docs
For comprehensive documentation — full API references, end-to-end SDK tutorials, architecture overviews — Studio Mode records screen and webcam as separate tracks with no time limits. Trim the intro, cut awkward pauses, and publish a polished technical video without a production team.
Changelog and Release Walkthrough Videos
Ship a short Cap recording with every major release. Walk through new API endpoints, breaking changes, and migration steps on screen. Developers reading your changelog get the context they need without parsing dense release notes. Link the video in your GitHub release, Slack announcement, or newsletter.
Password Protection for Private Internal Documentation
For internal runbooks, proprietary SDK documentation, or pre-release API previews, add a password to your recording or set an expiry date on the share link. Only developers with the link and password can access the video — no account required for viewers.
Self-Hosted Storage for Compliance and Data Residency
Organizations with documentation stored on internal infrastructure can configure Cap to upload recordings directly to their own S3-compatible bucket. AWS S3, Cloudflare R2, and MinIO are all supported. Video files never touch Cap's servers.

Why Developers Choose Cap for Documentation Videos
Developer documentation videos reduce support tickets and accelerate onboarding — here's how Cap compares to other tools
Cap vs Loom for Developer Documentation
Loom is a capable async video tool but limits recording quality and length on its free plan, and has no self-hosting option for teams with data residency requirements. Cap records at 4K with no recording-length limits in Studio Mode and supports self-hosted S3 storage. Cap is also fully open source under the MIT license — developers can audit the code, contribute features, and trust the tool they're using to document their own products.
Cap vs Written Documentation
Written docs are valuable but struggle to convey dynamic processes — API authentication flows, SDK initialization sequences, CLI command outputs. A 3-minute Cap recording showing an end-to-end API integration replaces a multi-page written guide that developers have to parse and mentally simulate. Video documentation reduces support questions and accelerates integration time for your users.
Cap vs Scribe for Technical Walkthroughs
Scribe generates step-by-step screenshot guides automatically, which works well for UI workflows but struggles with code, terminal output, and API responses. Cap records continuous video with audio narration, capturing the full context of a technical process — not just screenshots of discrete clicks. For developer documentation, video plus voice explains the why, not just the what.
Cap for Open Source Project Documentation
Open source maintainers can record quick demo videos and link them directly in their README, contributing guides, and release notes. Viewers see exactly how to install the library, run the examples, and use the main APIs — without a dedicated docs team. Cap is itself open source, so it's the natural choice for developers documenting open source projects.
Two Recording Modes for Every Documentation Workflow
Choose the right workflow for the type of documentation video you're creating
Instant Mode
Perfect for quick API demos, bug reproduction videos, and changelog walkthroughs. Record, stop, and share a link within seconds. Ideal when you need to document a new endpoint or explain a breaking change without spending more than a few minutes.
Studio Mode
Built for comprehensive SDK tutorials, end-to-end API walkthroughs, and developer onboarding videos. No time limits — record as long as your documentation requires. Separate screen and webcam tracks give you editing flexibility before publishing.

How Developers Use Cap for Documentation Videos
From API demos to internal runbooks, Cap fits every technical documentation workflow
API Reference and Endpoint Demos
Record a walkthrough of each key API endpoint — show the request format, authentication headers, response structure, and error handling. Embed the video in your API reference docs so developers see a working example before they write a single line of code. One video per endpoint dramatically reduces integration support tickets.
SDK Getting-Started Tutorials
Record a terminal session from package install through a working integration. Show npm install, SDK initialization, the first successful API call, and how to handle common errors. New developers watching the tutorial can follow along step-by-step without guessing which commands to run or how to interpret the output.
Changelog and Migration Guides
For every major release, record a short Cap video showing what changed. Walk through new features, demonstrate API changes, and show exactly what developers need to update in their integration. Link the video in your GitHub release notes and developer newsletter so your users understand changes without reading a wall of text.
Internal Technical Runbooks
Record runbook videos for complex operational procedures — database migrations, deployment pipelines, incident response workflows. Engineers on call can watch the video during an incident instead of trying to parse written steps under pressure. Password-protect runbooks containing sensitive infrastructure details.
Open Source Project README and Contributing Guides
Add a Cap demo video to your project README showing the library in action. Record a contributing guide showing how to set up the development environment, run the test suite, and submit a pull request. Lower the barrier to first contribution and accelerate new contributor onboarding without writing additional documentation.
Developer Onboarding and Internal Tooling Docs
Record walkthroughs of internal tools, deployment systems, and development workflows for new engineers joining the team. A library of video recordings replaces the traditional onboarding buddy pairing for standard procedures. New hires can watch, pause, and rewatch at their own pace. See how Cap supports developer onboarding.
