What is Cursor?

Cursor's Agent SDK turns custom agents into code projects you can test, then deploy anywhere.

Cursor has grown from an editor into a delivery platform: Projects coordinates cloud agents, Origin hosts repos with a 20+ app marketplace, Rollouts watches deploys, and the Environments API scripts agent sandboxes. On October 20 the Agent SDK went GA. An agent is now a folder with a prompt, typed tools, skills, MCP connections and channels, tested with evals and deployed either to Cursor or to the team's own infrastructure.

What is Pacemaker?

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

Cursor vs Pacemaker: editorial side-by-side

Cursor

7.5

Cursor's Agent SDK turns custom agents into code projects you can test, then deploy anywhere.

◆ Current state

Cursor has grown from an editor into a delivery platform: Projects coordinates cloud agents, Origin hosts repos with a 20+ app marketplace, Rollouts watches deploys, and the Environments API scripts agent sandboxes. On October 20 the Agent SDK went GA. An agent is now a folder with a prompt, typed tools, skills, MCP connections and channels, tested with evals and deployed either to Cursor or to the team's own infrastructure.

◆ Where it's heading

The last month has been about opening Cursor's agent stack to outside code: partner apps write into Origin, the Environments API exposes sandboxes, and the Agent SDK lets teams build their own bots on the same runtime. Agents that wake on PR, CI, Slack, webhook and cron events push Cursor past the IDE into always-on team automation. Cursor is selling the agent runtime itself, not just its own agents.

◆ Prediction

Expect more starter templates and SDK-built agents to appear in the app marketplace, and tighter links between SDK agents and Projects or Rollouts. Whether self-hosted deploys get the same dashboard tooling as Cursor-hosted ones is not yet clear from the entries.

6.3

Pacemaker is putting TLS and X509 auth between its cluster nodes, then hardening the wire code.

◆ Current state

Two branches ship in parallel: the 3.0.x line carrying new work and 2.1.x taking backported fixes. The 3.0 series added TLS for Pacemaker Remote nodes, X509 authentication, TLS certificates for remote CIB operations, and then PSK authentication for those same operations, alongside large-IPC and multipart message support. The most recent releases on both branches are the same security train, fixing CVE-2026-10649 and a set of integer overflows and size checks in the remote message code.

◆ Where it's heading

The cluster's internal transport is being rebuilt on the assumption that the network between nodes is not trusted. Authentication and encryption arrived first, and the fixes that followed, overflow guards and a maximum remote message size, are the hardening pass on the same code paths. Release discipline is heavy and visible: each version ships a release candidate with an identical commit set days earlier, and every 3.0 release documents the regressions it introduced and where they were fixed.

◆ Prediction

Remote CIB operations now support both X509 certificates and PSK, and the recent fixes all sit in message framing and size limits; further work is most likely to continue in that message-handling code rather than adding another authentication mechanism.
