Reelbird

Product Introduction

1. Definition: Reelbird is a free, open-source (MIT-licensed) screen recording application for macOS, built natively with Swift, ScreenCaptureKit, and Metal. It is a local-first, privacy-focused tool that enables users to record their screen, camera, and microphone, and generate instantly shareable links via their own cloud storage.
2. Core Value Proposition: Reelbird exists to combine the instant link-sharing workflow of cloud-based recorders like Loom with the advanced, post-recording polish features of tools like Screen Studio, all while maintaining user privacy, data ownership, and a one-time cost of $0. Its primary value is enabling a "record first, polish later" workflow where a shareable URL is available immediately after stopping a recording and can be updated with enhancements without changing the link.

Main Features

1. Instant Share Link Generation: Upon stopping a recording, Reelbird automatically copies a public, unlisted URL to the clipboard. This is achieved through a "Share while recording" mode that streams a 1080p video to a user-configured, S3-compatible storage bucket (e.g., Cloudflare R2, AWS S3, Backblaze B2, MinIO) during capture. The link is ready to paste and play in any web browser moments later.
2. Post-Recording Auto-Zoom & Polish: After recording, users can open the take and apply automated enhancements. The auto-zoom feature analyzes the event log (clicks, typing) to plan and apply smooth zoom-ins on areas of activity. The cursor is redrawn from log data to eliminate jitter and enable smooth gliding motion. Users can add captions (via Apple's on-device speech recognition), adjust the camera bubble position, mute tracks, and apply visual framing (backgrounds, shadows). Clicking "Update link" replaces the video in the cloud, preserving the original URL.
3. Crash-Safe, Segmented Recording & Advanced Audio Processing: Reelbird writes all audio and video tracks (screen, camera, mic, system audio) to disk in separate, 2-second segments from the first frame, minimizing data loss on application or system crash. Its audio pipeline includes auto-leveling to -16 LUFS, on-device voice enhancement (Apple's sound isolation), ducking (system audio dips when speaking), a de-esser, and a safety limiter at -1.5 dBFS to prevent clipping.

Problems Solved

1. Pain Point: The disconnect between quick, shareable recordings and polished, professional edits. Users often must choose between a fast tool that generates a link but lacks polish (Loom) or a powerful editor that requires manual export and upload (Screen Studio). Reelbird unifies this workflow.
2. Target Audience: Mac-focused creators like software developers, product managers, educators, and customer support agents who need to create quick tutorials, bug reports, demos, or async updates that look professional. Privacy-conscious users and open-source advocates who want control over their data and software. Technical users comfortable configuring a cloud storage bucket.
3. Use Cases: Async engineering stand-ups where a developer records a bug, shares the link immediately in Slack, and later adds zoom effects to highlight the issue. Creating software tutorials where the initial recording is shared for feedback, and final captions and smooth cursor effects are added before a public launch. Recording customer support responses that require clear audio and visual focus without complex editing software.

Unique Advantages

1. Strengths & Limitations (Pros & Cons):

   • Pros: Completely free (MIT license) with no feature limits, watermarks, or account required. Exceptional privacy: all processing is on-device, data stays local, and sharing uses your infrastructure. Unique "updateable link" workflow. Native macOS performance and efficiency. Crash-safe recording architecture. Includes a command-line tool and MCP server for automation.
   • Cons: Exclusively for macOS 15+. Requires initial technical setup of an S3-compatible bucket and CORS configuration (~10 minutes). Lacks team collaboration features like comments or view analytics found in commercial SaaS products. The editing interface is less mature than dedicated tools like Screen Studio.

2. Key Alternatives & Differentiation:

   • vs. Loom (Free Starter Plan): Loom provides instant links but limits free users to 5-minute 720p videos, 25 total videos, no downloads, and no auto-zoom polish. Reelbird has no duration/count limits, stores original MP4s locally, offers post-recording auto-zoom, and uses your storage.
   • vs. Screen Studio: Screen Studio offers sophisticated auto-zoom and editing but operates on a subscription model ($29/month) and does not provide an instant share link; links are generated after manual export. Reelbird provides the instant link first and allows polish later, all for free.
   • vs. QuickTime Player / macOS Built-in: These are basic recorders with no link generation, auto-zoom, cursor smoothing, or integrated audio processing. Reelbird adds a full production and sharing workflow on top of core recording.

Frequently Asked Questions (FAQ)

1. Is Reelbird really free? How does it make money? Yes, Reelbird is completely free under the MIT open-source license. It has no paid tiers, watermarks, or artificial limits. It does not make money; it's a community project. Users only pay for their own cloud storage (e.g., Cloudflare R2's free tier includes 10 GB and free egress).

2. Do I need to know how to code to use Reelbird's sharing feature? No coding knowledge is required for basic use, but you do need to follow a tutorial to set up a cloud storage bucket (like Cloudflare R2), generate API keys, and configure a public URL. This one-time setup takes about 10 minutes and is documented step-by-step.

3. What are the system requirements for Reelbird? Reelbird requires an Apple silicon Mac running macOS 15 (Sequoia) or later. It is a native Swift application that leverages modern frameworks like ScreenCaptureKit and Metal, which are not available on older macOS versions or on Windows/Linux.

4. How does Reelbird's privacy compare to Loom or Screen Studio? Reelbird's privacy model is fundamentally different. Loom and Screen Studio process and store your videos on their company servers. Reelbird keeps all recordings, edits, and captions locally on your Mac (~/Movies/Reelbird). Captions use Apple's on-device speech recognition. Only videos you explicitly choose to share are uploaded, and they go to a storage bucket you own and control.

5. Can I use Reelbird for recording long presentations or meetings? Yes, Reelbird imposes no recording time limits. However, practical limits are defined by your Mac's available disk space (as it records losslessly) and your configured cloud storage quota. The crash-safe segmented recording makes it reliable for long sessions.
