Platform Statistics & V7 Launch Announcement

• Wild year and a half since launch: 8+ million files uploaded
• Hundreds of thousands of users, tens of thousands of applications
• 6 months of development for complete overhaul (internal/external)
• V7 launch: up to 5x faster upload speeds
• Dog-fooding V7 with pic thing since launch

Key V7 Features & Improvements

• Speed: Up to 5x faster uploads (especially for smaller files)
• Reliability: Pause/resume functionality for uploads (S3 can't do this)
• Framework Support: Added Remix support package
• Legacy Infrastructure: Started shutting down original S3 direct upload system
• Upgrade Process: Zero code changes required for many users - just package swap + environment variable change

Performance Benchmarks

• Small files (800KB): 4 seconds → 0.5 seconds (377% faster)
• Multi-image test (4x ~1MB files): 5 seconds → 1.5 seconds
• Network conditions: 5ms latency San Francisco gigabit connection
• Scaling: Performance now scales better with file size/count vs fixed overhead

Technical Architecture Changes

Old V6 Architecture (7 request hops):

• User browser → Your server → UT API → S3 direct upload
• S3 completion trigger → Lambda → UT API → Your server → User polling
• Ghost files possible (security issue)
• No upload validation/processing capabilities
• Complex polling mechanism required

New V7 Architecture (3 request hops):

• User browser → Your server (self-signed) → UT Ingest Server → S3
• Connection held throughout upload
• Direct response forwarding from your server back to user
• Eliminated polling entirely

Infrastructure & Bundle Improvements

• New Ingest Server: Custom Fastify-based server (no longer serverless)
• Bundle Size Reduction: 30% reduction on top of previous 84KB cut
• Final Bundle: 15.6KB minified + gzipped
• Regional Deployment: Ingest servers in all UT operating regions
• Token Structure: New upload thing token (replaces simple secret)
  • Combines: secret + app ID + region
  • Eliminates round-trip API calls for server selection

New Capabilities Unlocked

• File Processing: Server-side file processing/validation
• Security: Automatic file scanning for illegal content (future paid feature)
• Compliance: Better path for HIPAA/SOC2 compliance
• Bring Your Own Bucket: Now possible with new architecture
• Self-Hosted: Future ability to deploy UT server in customer infrastructure
• Resume Uploads: Spotty connection handling
• Real-time Validation: File size, capacity, safety checks during upload

Team & Development

• Key Contributors: Julius (infrastructure), Mark
• Development Timeline: 6-month focused effort
• Work Impact: Held up other development during this period
• Relief: Team excited to ship after long development cycle

Business Direction

• Enterprise Ready: No longer just for hobby projects
• Sales Process: Schedule calls available for business customers
• Future Features: Many new capabilities now unlocked by architecture change
