Unity WebGL service

Unity WebGL optimization for builds that need to ship

I diagnose build-size, loading, memory, compression, hosting, and browser compatibility problems, then turn the findings into a practical deployment plan or focused implementation sprint.

Problems this service addresses

Oversized builds

Large asset payloads, duplicated content, unsuitable import settings, and unnecessary runtime dependencies can make browser delivery impractical.

Slow initial loading

Startup work, asset sequencing, caching, and the shape of the first download all affect how quickly a player reaches a usable experience.

Compression and hosting

Brotli or gzip files need matching server headers, MIME types, cache rules, and fallback behavior. A correct Unity export can still fail behind a misconfigured host or CDN.

Browser and memory limits

WebAssembly memory, decompression overhead, GPU resources, and tab limits require decisions that differ from desktop builds.

Mobile-browser constraints

Mobile browsers bring tighter memory budgets, slower CPUs, touch requirements, and more aggressive lifecycle management.

Deployment readiness

The final build needs repeatable settings, tested hosting behavior, observability, and a handoff the team can operate.

How the audit works

  1. Reproduce and measure. Review the project, exported files, network waterfall, browser console, memory behavior, and current hosting setup.
  2. Identify constraints. Separate asset, code, Unity configuration, runtime, compression, and infrastructure causes.
  3. Prioritize the work. Rank changes by likely impact, risk, effort, and dependencies.
  4. Validate deployment. Test the resulting build and document the configuration needed to host and maintain it.

Typical deliverables

  • Build-size and asset breakdown
  • Loading and runtime bottleneck report
  • Compression, caching, and hosting configuration review
  • Prioritized remediation plan
  • Implemented fixes when a hands-on sprint is agreed
  • Deployment and handoff notes

Who it is for

Studios, agencies, founders, and product teams with an existing Unity browser build that is too large, slow, unstable, incorrectly hosted, or not yet ready for its target browsers.

The first step is an audit so scope and constraints are clear before implementation.

Demonstrated result

Case Study: 1.2GB → 68MB

See how I reduced a production Unity WebGL build from 1.2GB to 68MB by restructuring asset delivery and moving video content to CDN-based runtime streaming.

Bring the build, measurements, and target browsers.

I will help you identify what is blocking deployment and what to fix first.
