What it does
Overflow turns screen designs into interactive user-flow diagrams and design presentations. It offers canvas, prototype and story views for synchronous or self-guided design critique.
The editor runs on macOS and Windows; cloud presentations can be viewed in a browser.
To bring in Figma work, select the frames, open the Overflow plugin and choose the export density and whether to include Figma’s prototype connections. Sync to Overflow transfers them into the flow. Re-sync after changes while keeping frame names consistent: matching names update existing screens, while unmatched names create new screens. Existing connectors remain in place during the normal re-sync workflow.
Register to begin the 14-day trial; payment-card details are not required. Pro lists a US-dollar rate of US$19.95 per user per month, with 1 GB of cloud storage per user; EU customers are billed in euros. Monthly and annual subscriptions are available, with applicable VAT added separately.
There is no ongoing free plan after the trial. The editor and cloud sharing stop working when it ends, and shared presentations become inaccessible. Overflow says it retains account data for 60 days while you can activate a subscription, then deletes the account and its data.
