Base44 vs Claude Code and Cursor: keep building your app with a coding agent

The short version

“Base44 vs Claude Code” compares two different kinds of tool. Base44 is an app builder that also hosts your app and runs its backend. Claude Code and Cursor are coding agents: they read and change code wherever it lives, and host nothing.

You can use them together. As of October 2026, on the Builder plan and up, Base44 documents three ways to let your own agent work on a Base44 app:

1. Two-way GitHub sync. The agent works in a local clone, and changes reach Base44 when they’re merged to main.
2. The cloud sandbox. The agent edits the app’s code in place through the Base44 CLI, with no local copy. The app editor’s Send to Coding Agent sets this up for you.
3. The Base44 MCP server. Any MCP-capable assistant can create and edit projects, read and write records, and work in the sandbox.

In all three, the agent changes the code while the app keeps running on Base44: its database, sign-in, functions, integrations and publishing stay there. If you want an agent working on the whole app, the backend has to be in the repository too. That’s what a migrated repository gives you.

Builder or agent: what each one is

So the honest answer to “is Base44 or Claude Code better” is that they do different jobs. Base44 decides how your app is built and where it runs. An agent is a way of editing code, and it works the same whether the code runs on Base44, on your own server or anywhere else.

Three ways to point an agent at a Base44 app

All three need the Builder plan or higher, which costs $40 a month billed yearly as of October 2026.

1. GitHub two-way sync

An app owner connects the app to a GitHub repository once. From then on, changes made in Base44 are pushed to the repository automatically, and changes merged into the main branch come back to Base44. The branch has to be called main. You still click Publish in Base44 to make a change live.

To run the app locally, Base44’s GitHub guide has you clone the repository, install dependencies and the Base44 CLI, sign in with base44 login, link the clone with base44 link, and run base44 dev. Two details matter when an agent is driving:

• Local isn’t fully local. Functions run on your machine in Deno, and records live in an in-memory database that is cleared when you stop the server. Social sign-in and built-in integrations such as sending email or AI generation are forwarded to your live app, and automations don’t run locally.
• Remote mode touches real data. base44 dev --remote runs your frontend against the live backend, and Base44 warns that writes go to your production data.

With GitHub sync, your table definitions are managed in Base44 and aren’t in the repository. And once an app is connected, version history can’t restore versions from before the connection. Running a Base44 app locally covers the local setup in more depth.

2. The cloud sandbox

Every Base44 app has a sandbox: a private cloud environment holding the app’s code and running its development server, the same one the app editor uses. Your agent reaches it with base44 sandbox commands to list, read, search, write and edit files, run shell commands, and save checkpoints.

The quickest start is in the app editor: More actions next to Publish, then Send to Coding Agent, then pick a local agent or a web chat, and paste the prompt Base44 writes. To connect by hand, install the CLI (npm install -g base44@latest), run base44 login, and point the agent at the app’s ID. Base44 names Claude Code, Cursor and Codex as agents that work this way.

What to know before you hand it over:

• Changes are real immediately. Each edit is committed straight away and shows in the editor’s live preview. Publishing is still a separate step.
• There’s no merge. If your agent and the Base44 editor change the same file at the same time, the last write wins.
• Checkpoints are your undo. Ask the agent to create one before a risky set of changes, and restore it from version history if needed.
• Limits apply. 120 reads, 60 changes and 30 commands per minute per app. The folders that hold the app’s secrets and repository credentials are off limits.

Send to Coding Agent isn’t offered for mobile apps.

3. The Base44 MCP server

“Base44 MCP” can mean three different things, all documented by Base44:

• The Base44 MCP server at https://app.base44.com/mcp connects an assistant such as Claude, ChatGPT or Cursor to your Base44 workspace. It can create and edit projects (edits are handed to Base44’s own AI), list projects, read and change table definitions, query and create records, connect connectors, and use the same sandbox tools as the CLI. In Claude Code you add it with claude mcp add --transport http base44 https://app.base44.com/mcp, then sign in with /mcp. One warning from Base44’s docs: updating a table’s schema replaces its fields, and any field you leave out is removed.
• The Docs MCP server at https://docs.base44.com/mcp lets an assistant search Base44’s documentation. It needs no sign-in.
• App MCP is different again. It lets people connect their own AI assistants to your published app, to read or change its data, message its agents or run tools you choose.

Base44 also publishes skills for coding agents in the base44/skills repository, covering its CLI, its SDK and troubleshooting from function logs. They install into Claude Code with claude plugin install base44@base44-skills, and into Cursor and other agents with npx skills add base44/skills.

What stays on Base44, whichever route you take

The agent edits code. These parts aren’t code in your repository, so they keep running on Base44:

• The database and records, behind Base44’s API.
• Sign-in and your users, which Base44’s documentation says can’t be exported.
• Backend functions, which run on Base44’s function runtime once deployed.
• Integrations such as email and AI. Base44’s docs say integration calls always run on Base44 infrastructure, metered in integration credits.
• Automations, workflows, agents and connectors.
• Publishing, which stays a step in Base44.

That’s a reasonable setup for many owners. If you’re happy on Base44 and simply want to edit with a better tool, the sandbox or GitHub sync gives you that today. What Base44’s exports include covers the code side in more detail.

When you want the agent working on the whole app

Some owners want more than editing: an agent that can change the data layer, the sign-in, the functions and the hosting, because all of it is in front of it. That needs a repository that contains the backend, not just a client for someone else’s.

After an Unbase44 migration, your private GitHub repository holds everything: your app’s own React frontend, a Base44-compatible backend in Deno and TypeScript that serves sign-in, data, functions, files, AI and email integrations, automations, workflows and agents, plus Docker files. It also holds documentation written for people and for coding agents: a README, AGENTS.md, CLAUDE.md, and docs on the architecture, deployment, local development and the migration itself.

Agents pick those files up on their own. Claude Code reads CLAUDE.md at the start of every session and can also read AGENTS.md. Cursor supports AGENTS.md in the project root and in subfolders.

Working on a migrated app looks like this:

1. Clone your repository and run docker compose up to start the app locally.
2. Open Claude Code or Cursor in the folder. It starts with the project’s own instructions.
3. Work on a branch and review before you merge. On Railway, pushing to main deploys the app, so main is production.
4. AI features use your own key (OpenRouter, OpenAI, Anthropic or Gemini), and email goes through your own Resend account or SMTP server.

The server code in the repository is MIT-licensed, and once the move is done the app depends on nothing of Unbase44’s. A chat-based AI builder for after the move is coming soon; until then, a coding agent is how you keep building.
