What Loom actually does
Loom is an async video messaging platform founded in 2015 by Joe Thomas, Shahed Khan, and Vinay Hiremath. It was acquired by Atlassian in October 2023 for approximately $975M. At acquisition, Loom had 200,000+ customers and had recorded over 1.5 billion minutes of video (Automation Consultants). The platform is used primarily for team communication, product demos, code reviews, and client reporting — any context where a screen recording with narration communicates more efficiently than text.
Post-acquisition, Loom is migrating to Atlassian's infrastructure and administration system (began August 2025). Atlassian does not disclose Loom's revenue separately; it's included in Atlassian's FY2025 revenue of $5.2B. The migration has been accompanied by consistent quality complaints on Trustpilot, G2, and Reddit — lag, audio sync drift, and failed upload errors that Loom support acknowledges are infrastructure-related.
The pricing structure has changed significantly post-acquisition. Business + AI at $20/Creator/mo represents a doubling of the previous Business plan price, and AI features (transcription, summaries, chapters) are locked to this tier. The free Starter plan caps recordings at 5 minutes — the most effective upgrade trigger in Loom's history.
Screen and webcam capture
Cross-platform screen recording with optional webcam overlay and audio. Available via Electron desktop app, browser extension (Chrome/Firefox/Edge), and iOS/Android mobile apps. The capture quality and reliability is the core product experience.
Video transcoding and hosting
Real-time H.264 encoding during capture with chunked upload to CDN. Server-side transcoding to HLS for adaptive streaming. Videos are hosted on Loom's CDN and playable via shareable links without requiring the viewer to have a Loom account.
AI transcription and summaries
Automatic transcription, AI-generated summaries, chapter markers based on content, and filler-word removal (ums, uhs). All AI features are locked to Business + AI at $20/Creator/mo — the primary upgrade trigger after the 5-minute free cap.
Viewer landing page with engagement
Each video has a public landing page with playback controls, transcript, comments, emoji reactions, and call-to-action buttons. Viewer analytics show who watched, when, and for how long.
Team workspace and organization
Team-level video library with folders, shared spaces, and search. Workspace admins manage creator seats, default sharing settings, and custom domain for video share pages.
Custom branding on share pages
Replace Loom branding on video share pages with your own logo and colors. Available on Business+ plans. Critical for agencies delivering branded video reports to clients.

Where Loom falls short
Lag, audio sync issues, and failed uploads since Atlassian migration
Trustpilot, G2, and Reddit reviews from late 2025 document a consistent pattern of audio sync drift (video and audio out of sync on recordings), upload failures mid-recording, and playback lag on the viewer landing page. These issues correlate directly with Loom's infrastructure migration to Atlassian's systems (beginning August 2025). Users report losing recordings with no recovery option.
Business + AI at $20/Creator/mo doubled the old Business plan
Claap's 2026 pricing comparison documents that Loom's Business + AI plan at $20/Creator/mo is double the previous Business plan price. For a 25-creator agency team, this represents $6,000/yr versus the $3,000/yr many teams were paying before. The AI features bundled into the new tier (transcription, summaries) were previously available at no extra cost in some plans.
5-minute free cap severely limits usefulness
The Starter (Free) tier caps recordings at 5 minutes. Most meaningful screen recordings — code reviews, client walkthroughs, design feedback — run 7–15 minutes. The 5-minute cap functions as a hard paywall that forces upgrades on anyone using Loom for real work. This is the single largest user complaint across all review platforms.
AI features locked to highest consumer tier
Transcription, AI summaries, AI chapters, and filler-word removal — features that many users consider table stakes in 2025 — are exclusively available on Business + AI at $20/Creator/mo. Teams that need transcription for accessibility compliance or async communication clarity cannot get it on the $12.50/mo Business plan.
Confusing Atlassian.com vs Loom.com purchase differences
Post-acquisition, Loom can be purchased through either Loom.com or Atlassian.com, and the two storefronts offer different plans, pricing, and feature sets. Loom's own support documentation from 2024–2025 acknowledges the confusion. Teams that purchase through the wrong storefront find themselves locked into plan configurations they didn't intend.
Key features to replicate
The core feature set any Loom alternative needs — plus what you can improve on.
Screen + webcam + audio capture cross-platform
Screen capture uses the browser's Screen Capture API (getDisplayMedia) for browser extensions, and native platform APIs (Windows Graphics Capture, macOS ScreenCaptureKit) for desktop apps. Webcam overlay uses getUserMedia. Audio capture requires careful echo cancellation and noise suppression configuration. A Tauri-based desktop app (Rust + WebView) is the modern cross-platform approach — Cap's open-source codebase uses this architecture.
Real-time encoding and chunked upload
H.264 encoding during capture using WebCodecs API (browser) or FFmpeg binaries (desktop) produces a stream of 2–5 second chunks uploaded to S3 as the recording proceeds. This chunked approach means a recording is partially available for processing before it ends. MediaRecorder API handles encoding in the browser extension; native FFmpeg provides more encoding control in desktop apps.
Video transcoding pipeline (HLS/DASH)
Server-side transcoding converts raw uploads to HLS (HTTP Live Streaming) with multiple quality levels (720p, 1080p, 4K) for adaptive streaming. AWS MediaConvert or Mux.com handle transcoding as a managed service — building custom FFmpeg transcoding infrastructure adds significant operational complexity. Budget $0.02–0.07 per minute of video for transcoding on Mux.
AI transcription with summaries and chapters
Whisper (OpenAI or self-hosted) transcribes the audio track. GPT-4o post-processes the transcript to generate a summary, chapter markers (timestamps + titles), and identifies filler words for removal. The transcription job runs asynchronously after upload completes. Cost: ~$0.006/minute on Whisper API; ~$0.01/1K tokens for GPT-4o summarization.
Viewer landing page with comments and reactions
A public page at your domain (video.yourcompany.com/{video-id}) with a video player, transcript display, emoji reaction bar, and threaded comment input. HLS.js handles adaptive streaming playback. Comments are stored in PostgreSQL with real-time delivery via Supabase Realtime. Viewer analytics (watch events) stored per viewer session.
Custom branding on share pages
Per-workspace logo, color scheme, and custom domain. The custom domain requires DNS CNAME + SSL certificate provisioning. Video share pages should be Server-Rendered (Next.js) for fast initial load and OpenGraph meta tags for link previews in Slack, email, and social sharing contexts.
Team workspace with video organization
Workspace-level video library with folder hierarchies, search by title and transcript content, and shared spaces. PostgreSQL full-text search on transcript content enables searching video content by keyword — a powerful feature for teams that use video for async documentation.
Technical architecture
A Loom alternative is an async video platform with three distinct technical subsystems: (1) capture — cross-platform screen/webcam recording, (2) processing — transcoding, transcription, and AI summarization pipeline, and (3) delivery — CDN-backed video player with viewer landing pages. The video pipeline is the cost driver and the hardest engineering challenge. Managed services (Mux, AWS MediaConvert, Whisper API) dramatically reduce the pipeline complexity versus building on raw FFmpeg.
Desktop capture app
Tauri (Rust + WebView), Electron + Node.js, native Swift/Kotlin
Recommended: Tauri — smaller binary than Electron, Rust-based native screen capture, WebView frontend reuses your web codebase. Cap's open-source Tauri architecture is an excellent reference.
Browser extension
Chrome Extension + Screen Capture API, Web app (tab capture), PWA
Recommended: Chrome/Firefox Extension using getDisplayMedia and MediaRecorder API — covers 70%+ of Loom use cases without requiring desktop app installation. Ship the extension first.
Video processing pipeline
Mux.com, AWS MediaConvert + Lambda, self-hosted FFmpeg
Recommended: Mux.com — fully managed video infrastructure (upload, transcode, HLS delivery, player). ~$0.007/minute stored + $0.007/minute delivered. Eliminates the hardest infrastructure work. Budget $200–500/month for 25 active creators.
AI transcription and summarization
OpenAI Whisper API, Deepgram, AssemblyAI, self-hosted Whisper
Recommended: Deepgram for transcription (~$0.0043/minute, faster than Whisper API) + OpenAI GPT-4o for summarization and chapter generation. Triggered as background jobs via Inngest after upload completes.
Web platform (viewer pages + workspace)
Next.js App Router, Remix, Astro
Recommended: Next.js App Router — Server Components for fast video page initial render and OpenGraph meta, Client Components for HLS.js player and real-time comments.
Database
PostgreSQL (Supabase), PlanetScale, Neon
Recommended: Supabase — PostgreSQL with full-text search on transcripts, Realtime for live comments and viewer presence, Auth for workspace management. Everything in one service.
Storage and CDN
Mux (included), AWS S3 + CloudFront, Cloudflare R2 + Stream
Recommended: Cloudflare Stream if not using Mux — pay-per-minute storage ($5/1K minutes) with global CDN and no egress fees. Better economics than S3 + CloudFront for video workloads.
Complexity estimate
Complexity 7/10 — the video pipeline (encoding, transcoding, CDN delivery) is the cost driver and the hardest infrastructure challenge. Using Mux or Cloudflare Stream as managed services drops the pipeline complexity significantly. Plan for 3–5 months with a team of 3.
Loom vs building your own
Open-source Loom alternatives
Existing projects you can self-host or use as a starting point. Each has trade-offs.
OBS Studio
73KOBS Studio is the most popular open-source screen recording and streaming software (GPL-2.0). It handles screen capture, webcam overlay, audio mixing, and video export with professional-grade controls. Version 32.1.0 was released in 2026. While not a Loom equivalent (no cloud hosting, no sharing links, no viewer pages), OBS is the gold standard for capture quality and serves as the technical foundation for understanding screen recording architecture.
Screenity
18KScreenity is an open-source Chrome extension (GPL-3.0, changed from MIT in v3.0+) for screen recording with webcam, audio, and annotation tools. Version 4.3.1 was released in March 2026. It's a browser-based alternative to the Loom Chrome extension with local recording and basic editing capabilities.
Cap
9.6KCap is an open-source async video tool (AGPL-3.0) built with Tauri (Rust) for the desktop app and Next.js for the web platform. It provides screen recording, cloud upload, and shareable video links — the closest open-source equivalent to Loom's architecture. Very actively developed as of 2026.

Breakeven vs Loom
At 25 creators on Loom Business + AI, the annual cost is $6,000/yr. A custom build at $100K–$200K breaks even in 17–33 years on cost alone — the pure replacement case is not compelling. The real drivers are verticalization and white-labeling. An agency building a branded async-video reporting tool for SEO clients can charge $50–200/month per client, generating $6,000–$24,000/yr per 10 clients — a break-even in 4–17 months. The video infrastructure costs (Mux: $200–500/month for 25 active creators) are real but manageable. Build if you have a vertical distribution advantage and can charge clients for the platform access; don't build as a pure Loom replacement.
DIY roadmap: build it yourself
This roadmap covers building a vertical async-video tool for client reporting using Cap's architecture as a reference. It assumes a team of 3 developers (1 senior, 2 mid-level) targeting a 25-creator agency deployment with client-facing video portals.
Capture and upload pipeline
4–6 weeks- Build Chrome extension using getDisplayMedia + MediaRecorder for screen/webcam capture
- Implement chunked upload to Supabase Storage with resumable upload protocol
- Integrate Mux.com for transcoding and HLS delivery — test upload and playback end-to-end
- Build recording status page: uploading, processing, ready states with progress bar
- Set up Tauri desktop app skeleton for teams that need native capture quality
- Implement Whisper API transcription triggered on Mux webhook (asset.ready)
Viewer platform and AI features
3–5 weeks- Build video viewer page in Next.js App Router with HLS.js player and transcript display
- Implement OpenGraph meta tags for rich link previews in Slack and email
- Add GPT-4o summarization: generate 3-sentence summary + AI chapter markers
- Build comment thread system with Supabase Realtime for live comment delivery
- Add viewer analytics: watch percentage, chapter completion, unique viewer count
- Implement emoji reactions and CTA button configuration per video
Workspace, branding, and client portals
3–4 weeks- Build workspace management with creator seat billing via Stripe
- Implement custom branding: per-workspace logo, colors, and custom domain for video pages
- Create client portal view: branded video library accessible to clients via invite link
- Add video organization: folders, tags, and full-text search across transcripts
- Build delivery report: send branded video summary email with watch analytics to client
- Set up Vercel deployment with custom domain and Cloudflare CDN configuration
The biggest timeline risk is the capture infrastructure — cross-browser and cross-OS capture has many edge cases (screen permissions on macOS, audio capture from specific apps, webcam latency). Budget an extra 2 weeks for QA across Windows, macOS, and Chrome/Firefox/Edge. The Tauri desktop app is a v2 feature unless native capture quality is critical for your market.
Features you can't get from Loom
This is where a custom build pulls ahead — features impossible or impractical on a shared platform.
Branded video delivery reports for agency clients
Automatically compile a weekly video digest email with thumbnails, watch rates, and a link to a branded client portal — positioned as a premium 'video reporting' service. Loom has no workflow for multi-video client delivery packages. This turns your video tool into a recurring service product with measurable client engagement data.
Searchable video knowledge base from transcripts
Build full-text search across all video transcripts so teams can find 'the video where Sarah explained the refund process' by searching 'refund process.' Loom's search is by title only. PostgreSQL tsvector on transcript content makes this a 1-day implementation — and it transforms async video from ephemeral communication to searchable institutional knowledge.
Video-based code review workflow
Integrate with GitHub to link recordings to specific PRs — video appears in the PR sidebar, timestamped comments in the video link to code lines. Loom has no GitHub integration for code review context. This makes async video a first-class part of the code review workflow rather than a separately-linked attachment.
AI-powered video training library with completion tracking
Build a training module layer where videos are organized into courses with required watch completion before proceeding. Add quiz checkpoints between videos and manager dashboards showing team completion rates. Loom has no LMS features. This vertical transforms async video into a lightweight internal training platform.
Automatic highlight reel generation
Use GPT-4o with transcript analysis to identify the 3 most important moments in a recording and generate a 90-second highlight clip. Loom has no highlight generation. Useful for sales teams wanting to extract key objections from a discovery call recording or for distilling a 30-minute design review to a shareable brief.
Who should build a custom Loom
Agencies delivering async video reports to clients
Agencies that use Loom to deliver project updates, SEO reports, and design reviews to clients pay $20/Creator/mo while showing clients a Loom-branded page. A custom tool provides white-labeled branded video pages, watch analytics per client, and automated delivery workflows — transforming Loom's use case into a billable service feature worth $50–200/month per client.
Teams frustrated by post-Atlassian quality degradation
The consistent post-migration issues (audio sync, upload failures, playback lag) documented throughout late 2025 represent a reliability regression that Atlassian has been slow to address. Teams with high-frequency recording workflows (daily standups, async code reviews) cannot tolerate infrastructure reliability issues. A self-controlled video pipeline eliminates the dependency on Atlassian's migration timeline.
Companies building internal training and onboarding platforms
Companies with high employee churn or distributed teams that record onboarding videos in Loom have no way to organize them into structured training sequences with completion tracking. A custom build can layer LMS-style features (course sequences, completion requirements, quiz checkpoints) directly on the video infrastructure.
Sales teams that need AI-enhanced call recording and analysis
Sales teams using Loom for async product demos are limited to transcription and basic summaries. A custom build can add objection detection (flag moments where the prospect says 'too expensive' or 'need to think about it'), sentiment analysis, and automatic CRM logging of key video moments — features that transform async demo review into a sales coaching pipeline.

Frequently asked questions
How much does it cost to build a Loom alternative?
Building a Loom alternative costs $100K–$200K for an MVP with screen/webcam capture, cloud video hosting, AI transcription, and viewer landing pages. The video infrastructure costs (Mux: $200–500/month for 25 active creators, Deepgram transcription: ~$0.004/minute) are the ongoing cost drivers. Using Mux or Cloudflare Stream as managed video services eliminates the hardest infrastructure work.
How long does it take to build a Loom clone?
3–5 months for an MVP with a team of 3. The Chrome extension with capture and upload takes 4–6 weeks. The viewer platform with AI transcription takes 3–5 weeks. Workspace management and custom branding takes 3–4 weeks. The Tauri desktop app for native capture quality adds another 4–6 weeks if required.
Are there open-source Loom alternatives?
Three options: OBS Studio (~73K GitHub stars, GPL-2.0) is the best screen capture tool but provides no cloud hosting. Screenity (~18K stars, GPL-3.0) is a Chrome extension with local recording. Cap (~9.6K stars, AGPL-3.0) is the closest Loom equivalent with Tauri desktop + Next.js web architecture and active development — the best fork base.
Can RapidDev build a custom Loom alternative?
Yes — RapidDev has built 600+ applications including video platforms, media processing pipelines, and agency client tools. Loom-style async video is one of our recommended vertical builds for agency clients. Visit rapidevelopers.com/contact for a free consultation.
What video infrastructure should I use for a Loom alternative?
Mux.com is the recommended managed video infrastructure — it handles upload, transcoding to HLS, CDN delivery, and provides a player API. Pricing is approximately $0.007/minute stored + $0.007/minute delivered, roughly $200–500/month for 25 active creators generating 30–60 videos/month. Cloudflare Stream is a cheaper alternative at $5/1,000 minutes stored. Avoid building on raw FFmpeg + S3 for v1 — the operational complexity is significant.
Why did Loom's quality degrade after the Atlassian acquisition?
Atlassian began migrating Loom from its original AWS infrastructure to Atlassian's central administration system in August 2025. The migration required re-architecting Loom's account management, billing, and storage systems. Trustpilot and G2 reviews from late 2025 document a pattern of audio sync drift, upload failures, and playback issues that Loom support acknowledges as migration-related. The issues represent the classic 'acquisition integration' infrastructure risk.
Can I import my existing Loom videos to a custom build?
Loom provides video download for Business+ users — you can download the original video files via the Loom API or web interface. Transcripts can be exported as SRT or text files. A migration script can download all videos and transcripts, re-upload originals to Mux or Cloudflare Stream, and re-import transcripts. The shareable links will change, but all content is preserved.
Does a custom build need a native desktop app from day one?
No — the Chrome extension using getDisplayMedia and MediaRecorder covers the majority of Loom use cases and can be built in 4–6 weeks. A native desktop app (Tauri) adds 4–6 weeks but provides better capture quality, system audio capture (not just browser audio), and lower CPU usage during recording. Ship the extension first; build the desktop app if users request it.
