Slack vs Zoho Sign: at a glance
What is Slack?
Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.
Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.
What is Zoho Sign?
Zoho Sign is clearing the exit path off Docusign while stacking up regional legal assurance
Zoho Sign publishes through the Zoho blog, so entries are announcement posts truncated to roughly 350 characters. The recent run splits three ways: legal assurance by jurisdiction — qualified electronic signatures for the EU through SIGN8, pan-India e-Stamping — client surfaces including a native Windows app, and agent access through Zoho MCP, where a prompt can send a document for signature and track it. The newest entry adds template migration from Docusign.

Slack raises the Marketplace bar back to ten installs while the agent platform consolidates.
◆ Current state
Slack's developer platform runs two tracks. The agent build-out has produced a spark roughly every two weeks since June — MCP client, a skills plugin targeting Claude Code and Cursor, and Slack Code — and now has a consolidation date attached: assistant_view is deprecated in February 2027, replaced by an Agent Sessions API. The second track is platform administration and tooling, and this window belongs to it: Marketplace submissions again require at least ten installed active workspaces, held throughout the review, after a period at a lower temporary threshold. The CLI has shipped three times since late July.
◆ Where it's heading
The install requirement moving back up is a distribution decision arriving in the middle of a platform push, and the two point the same way. Slack is making it easier to build agents and harder to list one, which favours developers who already have distribution — existing workspace tools and vendors — over a new app hoping the Marketplace supplies its first users. Combined with the assistant deprecation and the Agent Sessions API, the platform is narrowing on one agent surface and one class of builder rather than widening the funnel.
◆ Prediction
The threshold is described as a return from a temporary lower bar rather than a new policy, so the open question is what replaces the Marketplace as the discovery path for an app that cannot reach ten workspaces on its own. These entries do not answer it.

Zoho Sign is clearing the exit path off Docusign while stacking up regional legal assurance
◆ Current state
Zoho Sign publishes through the Zoho blog, so entries are announcement posts truncated to roughly 350 characters. The recent run splits three ways: legal assurance by jurisdiction — qualified electronic signatures for the EU through SIGN8, pan-India e-Stamping — client surfaces including a native Windows app, and agent access through Zoho MCP, where a prompt can send a document for signature and track it. The newest entry adds template migration from Docusign.
◆ Where it's heading
Two motions, both aimed at displacement. Zoho is assembling the assurance levels that let it be used for agreements a standard e-signature cannot carry, jurisdiction by jurisdiction, which is what removes the reason enterprises stay with an incumbent. And it is removing the switching cost directly: bringing Docusign templates across in minutes attacks the specific lock-in that keeps a customer on a platform whose documents are already built there. The MCP work runs alongside, making signature workflows something an agent initiates rather than a person.
◆ Prediction
Template migration is the first piece of a switching kit rather than the whole of it; expect the remaining Docusign artefacts — envelopes in flight, saved recipients, completed-document archives — to follow, since a template alone does not move a live signing operation.
