What is Scalar?
Scalar's mock server learns event-driven APIs while the reference UI picks up localization
Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.
What is Cursor?
Cursor launches Projects: a coordinator agent that runs thousands of subagents in the cloud indefinitely.
Cursor has moved well past AI code editor into multi-agent development infrastructure. It now coordinates parallel subagents on cloud machines, hosts code natively via Origin Repos, and maintains persistent project context that grows across sessions. The Projects launch adds a coordinator layer that can delegate tasks to thousands of subagents, run without a local machine, and react to external triggers like Slack or GitHub PRs.

Scalar's mock server learns event-driven APIs while the reference UI picks up localization
◆ Current state
Scalar ships as a monorepo, so the feed interleaves three release lines: the API reference (1.6x), the API client (1.1.x) and the mock server (0.1x). The June run brought AsyncAPI rendering to parity with dedicated tooling, added UI localization for seven languages with RTL handling, gave the client a requestBuilt hook for request signing, and taught the mock server to serve AsyncAPI documents over WebSocket and SSE.
◆ Where it's heading
AsyncAPI is the clear investment across all three packages — rendered in the reference, filterable in navigation, and now mockable as live event streams. The client and reference lines otherwise trend toward extension points and polish rather than new surface.
◆ Prediction
Expect AsyncAPI support to complete the loop by reaching the API client, so event-driven APIs can be exercised interactively the way REST endpoints already are.

Cursor launches Projects: a coordinator agent that runs thousands of subagents in the cloud indefinitely.
◆ Current state
Cursor has moved well past AI code editor into multi-agent development infrastructure. It now coordinates parallel subagents on cloud machines, hosts code natively via Origin Repos, and maintains persistent project context that grows across sessions. The Projects launch adds a coordinator layer that can delegate tasks to thousands of subagents, run without a local machine, and react to external triggers like Slack or GitHub PRs.
◆ Where it's heading
Every release since mid-2026 has added a new layer of the autonomous-software-pipeline stack: code hosting (Origin Repos), always-on event-driven agents (Subscriptions), parallel subagent execution (team pools, per-VM isolation), and now a coordinator agent that owns long-running Projects end-to-end. The pattern is consistent — each release removes a human touchpoint that previously required manual intervention.
◆ Prediction
The next move is likely billing and governance for agent-compute at scale. Projects running thousands of parallel subagents implies compute costs that don't fit per-seat pricing; enterprise contracts around agent-hours or compute credits are the natural next step, especially with the self-hosted pool infrastructure already in place.
