Cursor Live Apps alternative: build from any AI assistant

On 5 November 2026, Cursor launched Build Live Apps. You describe a tool to a Cursor cloud agent, and it builds the app, sets up a database and sign-in, and deploys it to a live URL your team can open. Their pitch is that "anyone in your org can now build useful tools for their work and share them with teammates."

That is the job Server4Agent has done since we started. It is good news to see another company build it, because it settles an argument we have been making for a year: the output of an AI conversation should be a working tool at a link, not a block of code to paste somewhere.

Where we differ is the starting point. Cursor's version is built for people who work in Cursor. Ours works from whichever AI app a person already uses: ChatGPT, Claude, Grok Bot, VS Code, Cursor itself, and any other app that supports MCP. This post sets out what each one does and how to choose. We make Server4Agent, so weigh our view with that in mind. Every Cursor detail below links to Cursor's own pages as they read on 6 November 2026, and a launch this new will change, so check them before you decide.

Quick answer

• Use Cursor's Build Live Apps when your whole team already works in Cursor on a paid plan with cloud agents. Building, sign-in, sharing and admin controls all stay in one place you already pay for.
• Use Server4Agent when your team is spread across different AI apps, or when the people who need tools (ops, sales, finance) do not work in a code editor at all. Each person connects the app they already use, once, and every request lands in the same projects at the same live links.
• They also combine. Cursor is one of the apps you can connect to Server4Agent, so the engineer can build from Cursor while the ops lead keeps using ChatGPT, on the same project.

What Cursor shipped

The facts, from Cursor's changelog and Apps documentation:

• The builder is a Cursor cloud agent. You "kick off a cloud agent and tell it explicitly that you want to build an app." The docs add that the feature is not supported on local agents.
• It sets up the plumbing. Cursor provisions a Postgres database when the app needs one, puts private apps behind sign-in, and deploys each app in a dedicated account it creates for your team.
• Code comes from Cursor Origin or GitHub. You can start from scratch or deploy an existing GitHub repository. GitLab is listed as coming soon.
• Viewers sign in with Cursor. Private and team apps "sit behind Cursor sign-in, so only the people you share with can open them." Public links are available on individual plans. On Teams and Enterprise, public sharing is off until an admin turns it on.
• Security checks run before every publish. Deterministic checks block secrets in files, credential files, .env files and source maps, and an AI review reads the app before it goes live. Team admins can see every app, add review rules and unpublish anything.
• It is on all paid plans with cloud agents enabled. No separate price for Apps is listed.

It is a thoughtful launch. The security checks in particular are the right instinct, and we would encourage anyone building this kind of product to copy them.

The question that decides it: where does the builder live?

Look at the list of people Cursor says the feature is for: ops tools, training material, sales dashboards, onboarding. Then look at which apps those people actually have open all day.

Inside most companies, the answer is not one app. Ops uses ChatGPT. The founder uses Claude. Someone in sales has started using Grok Bot. The one engineer who helps out works in Cursor or VS Code. We wrote about this pattern in how a team builds one tool when everyone uses a different AI assistant, and nothing about it has changed: people do not switch assistants because a tool told them to.

If the only way to get a tool built is to open a code editor and start a cloud agent there, the people who most need small internal tools are the ones least likely to build them. They will keep pasting the request to the engineer, which is the queue these products exist to remove.

So the useful question is not "which product builds better apps." Both can build a dashboard. It is "who on my team will actually ask for one, and from where."

How building from any app works

Server4Agent is a connector. You add it once to the AI app you already use, sign in, and from then on that app can build, host and change tools for you. The integrations page has the setup for each one:

• Chat apps: Claude, ChatGPT, Grok Bot and Muse connect as a custom connector, with a sign-in and no key to copy. AgentX connects as a tool in your workspace.
• Editors: Cursor and VS Code read a short config block. In Cursor it goes in ~/.cursor/mcp.json, and the editor and the command line both pick it up.
• Command line: Codex CLI, GitHub Copilot and Grok Build connect the same way.

The connector follows your account, not the app. That is what makes the cross-app part work: whichever app a request comes from, it reaches the same servers and the same projects.

Here is what that looks like at Pinegrove Robotics, a team of four.

The ops lead, in ChatGPT, asks for a page that tracks spare parts stock and flags anything below its reorder level. A few minutes later ChatGPT replies with a private link on apps.server4agent.com.

The founder, in Claude, opens the same project and asks for a weekly email summary of what was reordered. Same project, same link, now with a schedule.

The engineer, in Cursor, adds an import from the supplier's CSV export, because that part was fiddly and they wanted to read the code.

The sales lead never builds anything. They open the link on Monday morning.

Nobody switched apps, nobody pasted code into a thread, and there is one version of the tool. The activity log records who made each change, so when the reorder threshold moves, you can see who moved it.

Who can open the link

This is where the details matter, so here is exactly how it works today.

Every project starts private. It has its own address from the first minute, but that address serves nothing until you deploy it. When you do, you choose who gets through:

Two things follow from that table, and we want to be precise about both. Nobody needs a Cursor seat, or a seat in any particular AI app, to build with Server4Agent or to open what it built. But a team-only link does ask for a Server4Agent sign-in, and teammates who build on your account use seats on your plan. If you want a colleague, client or contractor to open a tool with no account at all, use a password link. The tradeoffs are covered in sharing an internal tool with your team without putting it on the internet.

Side by side

When Cursor's version is the better choice

Be honest with yourself about the shape of your team. If everyone who will build tools already works in Cursor, and your company already pays for it with cloud agents on, the Cursor version is the shorter path. Sign-in, sharing and admin controls sit inside a tool you already manage, the automatic Postgres saves a step, and the pre-publish security checks are a real safeguard. Adding another product for the same job would be overhead you do not need.

When Server4Agent fits better

• Your team uses more than one AI app. This is the main one. Each person keeps the app they like, and the work still lands in one place.
• The people asking are not engineers. An ops lead in ChatGPT can get a working tool without installing an editor or learning what a cloud agent is. Our non-technical guide to shipping real tools from chat walks through it from the start.
• The tool is more than a web page. A bot that holds a connection, a job that runs every ten minutes, or a page with a background worker all run on the same server.
• You want people outside the company to open it without creating an account, behind a password.
• You want one hard limit on spend. The account's budget cap covers compute and AI, and no assistant can raise it. AI agent pricing and budget caps explains how to size it.

FAQ

Can I use Server4Agent from Cursor?

Yes. Cursor is one of the apps you can connect. Add the config block from the integrations page to your Cursor MCP config, and Cursor can create, change and deploy Server4Agent projects. Teammates in other apps work on the same projects.

Do the people who open my tool need a Cursor seat?

No. They do not need a seat in any AI app. A public link opens for anyone, and a password link opens for anyone with the password. A team-only link asks them to sign in to Server4Agent as a member of your account.

Does Server4Agent set up a database for my app?

Not a managed one. Each app runs on a server with its own project folder on disk, and its data stays there between requests and restarts. For most internal tools, such as trackers, dashboards and forms, that is enough.

Is it only for chat apps?

No. Editors and command line tools connect too. Anything that supports MCP can use it, and the integrations page lists the current setup for each app.

What does it cost?

There is a free plan, and paid plans add servers, AI credit and seats. The current numbers are on the pricing page. Whatever the plan, the budget cap you set is the most it can spend.

Can I take a project somewhere else later?

Yes. Export the project and run the code anywhere. Nothing is locked to the app you built it from.
