Smooth Bundle is an asset publishing and delivery platform. It turns images, documents, scripts, styles, fonts and media into optimized, versioned, production-ready URLs for your apps, websites and CMS. Upload once, and Smooth Bundle handles processing, versioning, and delivery through stable URLs.
Managing and delivering web assets is messy: files get too large, URLs break, and versioning is manual. Smooth Bundle centralizes assets in one project, optimizes them for the web, creates responsive variants, and tags versions (e.g., latest, staging) for stable, predictable deployment.
It's for developers, agencies, and teams shipping websites or apps with regular releases. Use it in CI/CD, via CLI, API, desktop sync, or from a CMS. It's not for static brochure sites with occasional updates—there are simpler file hosts for that. It shines when you need controlled, versioned asset delivery at scale.
Smooth Bundle fits production websites with regular asset updates, client-site workflows for agencies, and apps that need image variants (WebP, AVIF) without manual processing. Protected assets allow restricted delivery for files that shouldn't be public.
