Mattermost
Mattermost leans hard into secure, on-prem collaboration for defense and regulated ops.
A side-by-side editorial comparison of Zoho Sign and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Zoho Sign grinds out integrations and country-by-country compliance, no single leap
Zoho Sign is a mature e-signature product shipping a steady stream of concrete additions: a Microsoft SharePoint integration, signer identity verification via Didit and Stripe, and expanding legally-binding coverage market by market. The feed is a product blog, but most entries here document real, shipped features rather than pure marketing.
Slack is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.

The feed is a product blog, but most entries here document real, shipped features rather than pure marketing.
Two axes are widening in parallel: workflow depth (SharePoint sync, sandbox testing, delegated signing, recipient managers) and regional compliance (pan-India e-Stamping, Nafath in Saudi Arabia, Colombia, Kenya's certified-signature mandate). Zoho Sign is competing on breadth of jurisdictional coverage and integration surface rather than a headline capability.
Expect more national identity and e-stamping integrations as new markets tighten e-signature rules, plus continued workflow tooling in the vein of sandbox and delegated signing. The cadence is incremental and steady, not punctuated by big bets.

The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
