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 TestingBot?

A browser grid that spent the summer becoming a team product, and is now opening itself to agents.

TestingBot runs a cross-browser and real-device cloud, and the last three months have gone almost entirely into what surrounds a test run rather than the run itself: custom roles enforced identically in dashboard and API, service accounts so pipelines stop borrowing a person's credentials, enforced two-factor authentication, comments with @mentions on failed runs, one-click filing into GitHub, Jira, Trello, Asana or Azure DevOps, and a notification inbox tying it together. The grid work continues underneath — WebRTC streaming for iOS simulators, a rebuilt web inspector, new devices and browser versions on the usual cadence.

Cursor vs TestingBot: editorial side-by-side

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.

5.0

A browser grid that spent the summer becoming a team product, and is now opening itself to agents.

◆ Current state

TestingBot runs a cross-browser and real-device cloud, and the last three months have gone almost entirely into what surrounds a test run rather than the run itself: custom roles enforced identically in dashboard and API, service accounts so pipelines stop borrowing a person's credentials, enforced two-factor authentication, comments with @mentions on failed runs, one-click filing into GitHub, Jira, Trello, Asana or Azure DevOps, and a notification inbox tying it together. The grid work continues underneath — WebRTC streaming for iOS simulators, a rebuilt web inspector, new devices and browser versions on the usual cadence.

◆ Where it's heading

Two directions are visible. The platform is being made safe for organisations rather than individuals, which is what roles, service accounts, 2FA and audit-friendly reporting add up to. Alongside it, the grid is being made reachable by software instead of people: an Insights API exposing pass rates and flakiness, embeddable build reports for CI dashboards, GitHub checks on every pull request, and now Vibium's CLI and MCP server pointed straight at the grid over WebDriver BiDi. The AI work so far reads results — failure analysis, documentation questions — while Vibium is the first path where something other than a human-written script drives the browser.

◆ Prediction

Expect the agent-facing path to be developed further, since supporting Vibium's MCP server without extra configuration is a small step from offering a first-party one, and expect the device and browser catalogue to keep rotating on its established cadence.
