Cursor vs Ably
Side-by-side trajectory, velocity, and editorial themes.
Stacking platform plays — SDK, security agents, fleet environments — in a single sprint.
Cursor is firing on multiple platform-expansion fronts at once. In the past month it has shipped: a programmable SDK that exposes its agent runtime to third-party developers, a Security Review surface with always-on PR security and vulnerability-scanning agents, configurable multi-repo development environments for cloud agents, and admin-side controls (model gating, soft spend limits, granular usage analytics). The cadence is weekly; the substance is platform-grade rather than feature-grade.
Cursor is migrating from "AI-native IDE" to "platform for AI engineering at organizational scale." The SDK turns it into infrastructure for other builders, Security Review creates a recurring always-on agent surface inside customer codebases, and multi-repo environments make fleets of parallel agents actually plausible in real engineering setups. Each release lowers the marginal cost of running many agents against one company's code.
Expect a bundled "agent fleet" tier for enterprise — environments, security agents, SDK access, model governance, and seat-level analytics priced together — within a quarter. Watch for tighter hooks into CI and observability so the output of these agent fleets becomes auditable and measurable, not just shippable.
Ably pivots its developer surface toward AI agents as first-class consumers
Ably's developer surface has been visibly pivoting toward AI agents over the last six weeks. The CLI hit v1.0 with structured JSON output envelopes, hint fields for self-healing agents, and unified --force semantics. Two weeks later v1.1 added `ably init`, which installs the CLI plus Agent Skills bundles directly into Claude, Cursor, Windsurf, and VS Code in one step. A new AI Transport SDK lands separately, with end-to-end tool-calling and React providers for the Vercel AI SDK.
Ably is building two integration stories in parallel — agents as CLI users (via Agent Skills) and agents as transport consumers (via the AI Transport SDK). Together they bracket the workflow: agents read live data through the SDK and operate Ably itself through the CLI. The traditional client-library stream (JS, Python, Laravel) continues at steady pace in the background, with LiveObjects formally graduating to GA on the protocol-6 update.
Expect the AI Transport SDK to add tool-call adapters for at least one more AI runtime beyond Vercel — most likely the OpenAI Agents SDK or Anthropic's Claude Agent SDK — and Agent Skills coverage to expand to additional AI clients (Cline, Aider, Continue). Watch for the LiveObjects API to surface inside the chat/AI surfaces.
