What is Payload CMS?

Payload v4 enters beta: redesigned admin, TanStack Start support and agent instructions.

Payload 4.0 moved from canaries to beta on October 9, bundling an admin UI redesign, TanStack Start as a second framework alongside Next.js, hierarchies, tags, grid view, upload versioning and a rewritten MCP server. Two betas followed within a week; beta.2 moves the TanStack adapter to stable TanStack Start and renames LLM instructions to agent instructions. The canaries also flipped the Local API to enforce access control by default.

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.

6.3

Payload v4 enters beta: redesigned admin, TanStack Start support and agent instructions.

◆ Current state

Payload 4.0 moved from canaries to beta on October 9, bundling an admin UI redesign, TanStack Start as a second framework alongside Next.js, hierarchies, tags, grid view, upload versioning and a rewritten MCP server. Two betas followed within a week; beta.2 moves the TanStack adapter to stable TanStack Start and renames LLM instructions to agent instructions. The canaries also flipped the Local API to enforce access control by default.

◆ Where it's heading

Payload is loosening its Next.js dependency and building agent features into the CMS itself: editors can manage instructions that flow into the CLI and MCP schemas, and upgrades come with an agent-assisted codemod. The betas are now mostly fixes and documentation, which points toward a stable 4.0.

◆ Prediction

Expect weekly betas focused on migration fixes and docs, with more framework-adapter work for TanStack Start. The entries don't give a 4.0 stable date.

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.
