Slack is quietly rebuilding itself as a runtime for third-party agents.
A side-by-side editorial comparison of Linear and Zoho Sign — release velocity, themes, recent moves, and the top alternatives to consider.
Linear closes the loop from issue to shipped code, with agents doing the writing.
Linear has spent the past two months turning its agent from a planning aid into a coding participant. Code Intelligence gave the agent codebase reasoning, MCP brought in external context, Diffs added native review, and Coding sessions now let it write and ship code with Claude Code and Codex. The project tracker is becoming the place where work is also executed, not just coordinated.
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.

The project tracker is becoming the place where work is also executed, not just coordinated.
The direction is unmistakable: Linear wants the full plan-write-review-ship loop to live inside its workspace. Each release this quarter has filled one gap in that loop, and the surrounding work (Slack/Teams channels, team documents, releases tracking) keeps feeding the agent more context to act on. Expect the boundary between Linear and the IDE/GitHub to keep blurring.
Next moves likely deepen the coding-session workflow visible in these entries: more review automation on top of Diffs, and tighter loops between agent-written PRs and deployment tracking via Releases.

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.
