How to choose

If you sign a handful of documents a week on one machine, the free edition is the whole answer. Move to PRO when you want templates, watermark-free stamps and text-anchor placement. Move to ENTERPRISE when signing stops being a person clicking a button and becomes a batch process.

Still deciding? The use-case page shows which tier each of the five observed signing desks ends up on.

Start on the free tier — no account, no card, no expiry.

Sign one document with your own DSC token and see the result in Adobe before you decide anything. Upgrading later keeps your settings and templates.
