What is Cursor?
Cursor is becoming a control plane for agent fleets — routed, governed, and driven from a phone.
Cursor has stopped shipping editor features and started shipping fleet management. The last two months added cloud VMs that run agents independently of the laptop, an iOS and now iPad client that launches and merges work from anywhere, Slack as a first-class agent entry point, and Bugbot as an automated reviewer in the pull-request path. Underneath all of it, Cursor Router now decides which model handles each request, with admins setting policy per team.
What is Fission?
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.

Cursor is becoming a control plane for agent fleets — routed, governed, and driven from a phone.
◆ Current state
Cursor has stopped shipping editor features and started shipping fleet management. The last two months added cloud VMs that run agents independently of the laptop, an iOS and now iPad client that launches and merges work from anywhere, Slack as a first-class agent entry point, and Bugbot as an automated reviewer in the pull-request path. Underneath all of it, Cursor Router now decides which model handles each request, with admins setting policy per team.
◆ Where it's heading
Every surface added this quarter points the same way: the agent is the unit of work, and the IDE is only one of several places you supervise it from. The admin-facing releases — team marketplaces, distributed MCP servers, org-group access, router policy and model block lists — are assembling an enterprise control plane around that fleet. Cursor is competing less on editing quality and more on whether an organization can run, route, price, and audit many agents at once.
◆ Prediction
The entries name their own next step: Bugbot's /review is explicitly marked "coming soon" to the CLI, and Cursor Router already spans desktop, web, iOS, CLI, and SDK — so expect review and routing to reach parity across every surface next. Finer-grained router policy, scoped per repo or per task rather than per team, is the natural follow-on to the admin controls just shipped.
Fission

Fission's release feed carries only RC tags, and none of them say what shipped
◆ Current state
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
◆ Where it's heading
What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
◆ Prediction
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.
