OnceLink: features, pricing and alternatives

About OnceLink

OnceLink creates links that can be opened a single time. You upload a file or paste text, it is encrypted with AES-256 using zero-knowledge encryption so even OnceLink cannot read it, a password is generated, and the link permanently deletes the content after the first view.

The site gives use cases such as development secrets like API keys and tokens, financial documents, legal contracts, access credentials, medical records, design assets, photography deliveries and personal ID documents. An API automates creating, listing and revoking one-time links, data can be stored in three global regions, and the site is available in English and Portuguese. A free plan lasts indefinitely with no credit card, and premium plans are on a pricing page.
