Evidence brief · Updated 2026-05-21

Website builder CMS, bandwidth, and publishing limits

Agencies and founder-led SaaS teams hosting CMS-heavy, image-heavy, or video-heavy marketing sites where bandwidth, CMS, custom-domain, and client-handoff limits can change project margin.

Claim boundary: Webflow has an official May 2026 pricing and plan-change document with a Business-to-Premium bandwidth reduction and add-on scenarios. Use Webflow as the named wedge; keep Wix, Framer, Squarespace, WordPress.com, and Carrd as current-state monitoring rows until dated changes are captured.

Confirmed 2026 bandwidth and pricing transition

Strongofficial dated change

Official Webflow help says Site plan changes went live for new purchases on May 13, 2026 and existing eligible sites begin moving on June 29, 2026. For Business plan users, bandwidth decreases from 100GB to 50GB, add-ons are added when recent usage exceeds 50GB, and sample yearly scenarios show total monthly cost can rise from $59 to $65 when covering 150GB usage.

Campaign angle: A Webflow alternative for agencies whose client sites need predictable bandwidth and CMS hosting costs before renewal, handoff, or a billable plan change.

Wix

Current free hosting and custom-domain pressure

Mediumofficial current

Official Wix help says free hosting includes 500MB storage and 500MB bandwidth on a Wix subdomain; connecting a custom domain requires upgrading the site with a plan.

Campaign angle: A Wix alternative for service businesses and agencies that need a custom-domain launch without free-site branding and low storage headroom.

Public reaction and risk boundary

Reaction evidence helps turn plan limits into affected segment language. It does not prove a vendor-side change by itself.

Reddit r/webflow

CMS launch confusion

Webflow users publicly discuss confusion when CMS work prototyped on a free site cannot simply move to a Basic custom-domain plan.

GTM implication: The best campaign angle is launch-readiness and client handoff clarity, not a generic website-builder comparison.
