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 Firecracker?
Firecracker adds PCI device hotplugging and virtio reset — microVM lifecycle management takes a meaningful step.
Firecracker is Amazon's open-source microVM hypervisor, used as the isolation layer for Lambda and Fargate. Recent releases have been focused on expanding the microVM lifecycle model: v1.16.0 added developer preview PCI virtio device hotplug (block, pmem, net), v1.17.0 adds virtio device reset support and richer metrics emission (instance ID and operator-defined properties). The release cadence has accelerated — multiple patch releases within the same minor version cycle.
Cursor vs Firecracker: editorial side-by-side
Cursor
7.5INFRA · APIS
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.
Firecracker
5.0INFRA · APIS
Firecracker adds PCI device hotplugging and virtio reset — microVM lifecycle management takes a meaningful step.
◆ Current state
Firecracker is Amazon's open-source microVM hypervisor, used as the isolation layer for Lambda and Fargate. Recent releases have been focused on expanding the microVM lifecycle model: v1.16.0 added developer preview PCI virtio device hotplug (block, pmem, net), v1.17.0 adds virtio device reset support and richer metrics emission (instance ID and operator-defined properties). The release cadence has accelerated — multiple patch releases within the same minor version cycle.
◆ Where it's heading
The hotplugging work in v1.16.0 is the most architecturally significant change in this window: being able to attach and detach storage and network devices from a running microVM without restarting it opens up dynamic workload scenarios that previously required a full cold start. The v1.17.0 metrics additions (instance ID emission, operator-defined key-value pairs) suggest growing operational observability requirements from fleet operators running Firecracker at scale.
◆ Prediction
The PCI hotplug is still developer preview — GA is the likely near-term milestone. Automatic guest notification for hotplug events (currently requiring manual PCI bus rescan) is the obvious follow-on feature. The metrics expansion suggests more structured telemetry is coming to support fleet-level observability tooling.
