What is Dropbox Sign?

Dropbox Sign's API can now check a PDF's fields before a signature request goes out

Dropbox Sign's changelog is mostly API work and documentation. The October release adds POST /v3/document/detect_fields, which analyses a PDF for form annotations or Text Tags and returns reusable field definitions with warnings and errors before anything is sent. Expiration dates now work on template-based, embedded and bulk sends, and can be added to an existing request. Earlier changes raised the per-request file limit to 100 and began a gradual rollout of a redesigned mobile signing page.

What is CryptPad?

CryptPad rebuilt its server and swapped its office engine; now it is patching the fallout.

CryptPad just shipped its largest architectural change in years: a rewritten server published as a standalone npm package, and office apps moved from OnlyOffice to Euro-Office 9.3. Three weeks later a fix release followed with team-deletion, sharing and eviction-script repairs plus security fixes rated up to CVSS 7.3. The product is an end-to-end encrypted suite whose release rhythm is seasonal: one feature drop, then one or two fix releases.

Dropbox Sign vs CryptPad: editorial side-by-side

D2.5

Dropbox Sign's API can now check a PDF's fields before a signature request goes out

◆ Current state

Dropbox Sign's changelog is mostly API work and documentation. The October release adds POST /v3/document/detect_fields, which analyses a PDF for form annotations or Text Tags and returns reusable field definitions with warnings and errors before anything is sent. Expiration dates now work on template-based, embedded and bulk sends, and can be added to an existing request. Earlier changes raised the per-request file limit to 100 and began a gradual rollout of a redesigned mobile signing page.

◆ Where it's heading

The visible work targets developers who generate signature requests programmatically: fewer failed sends, and the same options across every send path. It is steady API maintenance rather than new product territory.

◆ Prediction

More endpoint parity work is the likely next entry, given that expiration support was just extended to the remaining send endpoints.

6.3

CryptPad rebuilt its server and swapped its office engine; now it is patching the fallout.

◆ Current state

CryptPad just shipped its largest architectural change in years: a rewritten server published as a standalone npm package, and office apps moved from OnlyOffice to Euro-Office 9.3. Three weeks later a fix release followed with team-deletion, sharing and eviction-script repairs plus security fixes rated up to CVSS 7.3. The product is an end-to-end encrypted suite whose release rhythm is seasonal: one feature drop, then one or two fix releases.

◆ Where it's heading

The office suite is the recurring pressure point: nearly every release since 2025 carries OnlyOffice corruption, history or pinning fixes, and the Euro-Office swap is the team taking ownership of that dependency. Splitting the server into its own package points toward easier self-hosting and embedding, which matches the openDesk integration builds and Integration API work seen earlier in the year.

◆ Prediction

Expect another fix release within weeks addressing new-server and Euro-Office edge cases, then a winter feature release built on the new server. Whether the server package gets third-party adoption is not visible from these entries.
