The short version

  • Only Webflow has a free tier, so it costs nothing to try first.
  • Each has a real cost: Proto.io prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given.; Webflow does not support user authentication or password management; feature removed January 2026
  • They diverge on capability: Proto.io covers Event and condition system, Webflow covers Visual designer.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Proto.io

  • Prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given.
  • Design is done elsewhere and interaction is rebuilt here, so every change to the visual design has to be reapplied by hand and the two artefacts drift apart.
  • The event and condition model is layer based, so a genuinely complex flow becomes a large tree of triggers that nobody but its author can audit.
  • Editor seats are priced individually and viewer access is limited on lower plans, so opening review to a wide stakeholder group pushes you up a tier for people who never edit anything.
  • The market standardised on Figma, so hiring people who already know Proto.io is progressively harder and every new researcher is a training cost.

Webflow

  • Does not support user authentication or password management; feature removed January 2026
  • Does not automate workflows natively; feature removed June 2025
  • CMS rendering constraints limit scalability: 40 Collection lists per page, 100 items per list, 20,000 items total
  • E-commerce capabilities are limited compared to dedicated platforms
  • Hosting lock-in prevents exporting sites to other platforms; no full server-level access for advanced SEO customizations

Answered from the vendors’ own pages

Proto.io: Can it replace Figma?

No. It has no design system or file-handoff role. It sits alongside Figma for the prototypes Figma cannot express.

Webflow: Does Webflow have a free plan?

Yes, Webflow's Starter plan is free with the Webflow badge visible on sites. It allows up to 2 projects with 2 pages per site, hosted on webflow.io subdomain. Full functionality requires upgrading to paid Site plans.

Proto.io: What happens to prototypes if we stop paying?

They stop being accessible unless you have exported them, and offline export is restricted to higher plans, so plan archiving before you cancel.

Webflow: What are Webflow's current paid plans and pricing?

Webflow's Site plans start at $15/month (Basic), $25/month (Premium), or custom for Enterprise when billed annually. As of May 2026, Webflow merged CMS and Business plans into Premium at $25/month yearly, including 40 CMS Collections and 20,000 CMS items.

Source
Proto.io: Is it worth learning now that InVision has gone?

If your work is usability research on conditional flows, yes. If you need click-through demos of static screens, Figma already does that at no extra cost.

Webflow: Does Webflow support user authentication?

No, Webflow removed native user authentication and password management in January 2026. For projects requiring login systems or user management, Webflow is not suitable.

Source
Webflow: How does Webflow integrate with other tools?

Webflow integrates with Zapier supporting 5 triggers, 7 actions, and 2 searches without code. It also supports webhooks for real-time events like CMS item creation and form submissions through Zapier's Webhook connector.
