What we focus on

Focused depth for one demanding problem domain.

Web Forms specialization

Built for the ASP.NET Web Forms page lifecycle, server events, and ViewState model, not a generic JavaScript widget bolted onto a .aspx page. Drop <au:AjaxFileUpload /> in, wire OnFileUploaded, ship.

Modern transport stack

7 strategies in 5.3: classic, chunked, direct-to-S3, direct-to-Azure, direct-to-GCS, tus 1.0, and server-side URL import. Pick per-page or per-file. Bytes can skip IIS entirely.

Security & compliance built-in

Client-side AES-GCM encryption-at-rest, virus-scan hook with quarantine, antiforgery integration, role-based gating, and rate-limiting demos for HIPAA- and GDPR-sensitive workflows.

Long-term product maintenance

Shipping since 2003 with regular major upgrades. The CuteWebUI compatibility shim still keeps 4.x pages compiling on 5.3 with zero edits.
