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 Dragonfly?
Dragonfly fixes dropped writes during slot migration and rebalances slot-based sharding.
Dragonfly is maintaining two incremental lines, 1.40 and 2.0, with small, targeted releases. The 2.0 line fixed a slot-migration bug that silently dropped journal writes into empty buckets and changed experimental slot-based sharding to Fibonacci hashing so keys spread evenly. The 1.40 line received BLMOVE and Sidekiq queue-placement optimizations.

Cursor

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.
Dragonfly
5.0INFRA · APIS
Dragonfly fixes dropped writes during slot migration and rebalances slot-based sharding.
◆ Current state
Dragonfly is maintaining two incremental lines, 1.40 and 2.0, with small, targeted releases. The 2.0 line fixed a slot-migration bug that silently dropped journal writes into empty buckets and changed experimental slot-based sharding to Fibonacci hashing so keys spread evenly. The 1.40 line received BLMOVE and Sidekiq queue-placement optimizations.
◆ Where it's heading
Most of the work is in cluster mode: migrations, slot placement and topology replies. That suggests the 2.x line is being hardened for multi-node deployments, while 1.40 still gets backports and small performance fixes.
◆ Prediction
The slot-based sharding flag looks likely to stay experimental for a while, with more balancing and migration fixes before it becomes a default.
