Vibe Coding vs Agentic Coding: The Real Difference

Vibe coding and agentic coding answer different questions. Vibe coding is about how closely you look: you prompt, try the result, and may never read the code. Agentic coding is about who does the work: an agent plans, edits files and runs commands in a loop while you set the goal and the limits. You can do either one without the other.

Definitions

Vibe coding. Per the Wikipedia article on the term, it is software development where a person describes a project to a language model that writes the code, and it may involve accepting the output without thorough review. Andrej Karpathy coined it in February 2025. The defining habit is relying on results and follow-up prompts rather than on reading the code.

Agentic coding. There is no single authority for this term, so here is how we use it. An agentic coding tool works in a loop: it reads files, makes a plan, edits several files, runs commands such as tests, reads the output and tries again, until a stated condition is met. Claude Code, Codex, Cursor's agent and similar tools work this way. What makes it agentic is the loop and the tools, not whether a human reviews the result.

That second point is where people get confused. The two words describe different axes.

So there are four combinations, and each one is real.

Most disagreement online is people discussing different boxes. When someone praises "agentic coding" they usually mean the bottom left. When someone warns about "vibe coding" they usually mean the right column.

The differences that matter in practice

Who holds the plan

In vibe coding you steer prompt by prompt, and the plan lives in your head or nowhere. In agentic work, a good setup asks the agent to produce a plan first, which you read. Claude Code has a plan mode for this: a read-only research phase before any edit. A written plan is a cheap place to catch a wrong approach.

What checks the work

Vibe coding checks by trying the app. Agentic coding can check by running commands: tests, type checks, linters. The Claude Code best-practices page says Claude stops when the work looks done, and that without a pass or fail check, looking done is all it has. It lists levels of strictness, from asking in the prompt, to a Stop hook that blocks the turn from ending until a script passes, to review by someone who did not write the change. See our best practices guide for the config.

How much it can do at once

A chat prompt produces a snippet. An agent can touch dozens of files in one go. That is the strength and the hazard. A mistake spreads further, and a reviewer needs better tools than "scroll through it". Diffs, tests and version control matter more, not less.

What can go wrong

Both modes share the biggest risk, which is unreviewed code reaching users. Agents add a new one: an agent with broad permissions can delete, overwrite or send things. That is why permission rules, hooks and sandboxes exist.

Controls that turn vibes into agentic discipline

Here is what separates a careful agentic setup from a vibe session using the same tool.

1. A written instruction file. A short CLAUDE.md or AGENTS.md with the test command and the rules. See how to write a good CLAUDE.md.
2. Permission rules. Deny rules hold in every permission mode in Claude Code, so secrets stay out of reach.
3. Hooks. A hook runs at a fixed point whatever the model decides. It can format after each edit, block edits to protected files or refuse to stop until tests pass. See the hooks guide.
4. A reviewer that did not write the code. A read-only subagent starts without your chat history and gives an independent read.
5. Version control. Branch, commit often and open a pull request. Diffs are how you read an agent's work.
6. A human at the merge. Nothing ships because the agent said so.

Notice that none of these require you to write the code. They require you to keep the checks.

When to use which

Vibe coding tools for non-developers include Lovable, Bolt and Replit. See best vibe coding tools. For terminal and editor agents, see AI coding agents and how to choose one.

A worked contrast, with example figures

Take one task, adding an export button to a small app, done two ways. The numbers are examples to show the shape, not measurements.

Vibe style. You tell a builder "add a button that exports orders as a file". It adds one. You click it, a file downloads, you move on. Total time: ten minutes. What you did not learn: whether the file contains other customers' orders, whether a very large export times out, or whether the button works for a user without permission.

Agentic style. You ask an agent to plan the change first and read the plan. It proposes a route, a permission check and a test. You approve. It writes the code, runs the test suite and reports the output. You read the diff, and a reviewer subagent flags that the query lacks a limit. You ask for a fix. Total time: thirty minutes. What you learned: the export is scoped to the signed-in user, large exports are capped, and a test proves both.

For a personal app, the ten-minute version may be right. For an app with customers, the extra twenty minutes are the cheapest insurance you will buy.

A path from vibes to agentic discipline

If you started with vibes and now have something real, you do not need to rebuild. Move one habit at a time.

Each step is small and none needs a rewrite. After six weeks you are doing agentic coding with review, using the same tool you started with.

Questions teams ask

Do we need a policy? A short one helps. State which kinds of work may be done without review, such as internal scripts and prototypes, and which must be reviewed, such as anything touching customer data or money. People follow a policy that is short and specific.

Who is accountable for agent-written code? The person who merges it. Say so in writing. If an agent wrote it and you approved it, it is your change.

How do we review faster? Make the diff small. Ask the agent for one concern per branch, have it run the tests before it reports, and use a read-only reviewer subagent for a first pass. Small diffs and passing tests make a human review a matter of minutes.

What about junior developers? Agents can speed up learning if the junior reads the diffs and asks the agent to explain them. They hurt learning if the junior accepts everything. Pair juniors with a reviewer for the first few weeks and ask them to explain each change in their own words.

How do we limit risk with permissions? Start restrictive. Allow reads and edits in the working folder, deny secrets and production credentials, and ask before network access or installs. Loosen only where you have seen the agent behave well. Claude Code's deny rules hold in every permission mode, which is why secrets belong there.

Agentic coding costs more than a chat

An agent loop reads many files and runs many commands, so it spends more tokens than a single chat answer. That is a reasonable price for the checks, and it is still a price. Watch for loops where the agent retries the same failing step. Set a turn limit where the tool allows one, and read the plan when a run goes long. In Claude Code, subagents can set maxTurns, and output is marked partial if the limit is reached. Our pricing comparison shows how each tool meters usage.

Tools by mode

Most tools support both modes, so the tool does not decide. Your habits do. Still, tools lean in different directions.

• Builders such as Lovable, Bolt and Replit lean toward vibe coding. They hide the code behind a preview and make the first version fast. Several offer Git sync or code access, which lets you add review later.
• Editor agents such as Cursor sit in the middle. You see diffs and can accept or reject them file by file, so review is built into the flow if you use it.
• Terminal agents such as Claude Code and Codex lean toward agentic work. They run commands and tests, and they support permission rules, hooks and subagents that turn checks into configuration.

Pick the tool that matches the discipline you plan to keep, then use its controls. A builder with Git sync and a habit of reading diffs can be safer than a terminal agent run with every permission open. The label on the tool counts for less than what you check before you ship.

Do the words matter?

Yes, because they steer expectations. If a manager hears "vibe coding" and thinks it means "AI-assisted engineering", they may approve a practice nobody should apply to payments. If an engineer hears "agentic" and thinks it means "no human needed", they may remove the review that makes it safe. Use the words precisely: vibe coding for the review habit, agentic for the loop.

There is also a vendor angle. Marketing for coding tools uses both terms freely, and "agentic" tends to signal capability while "vibe" signals ease. Neither tells you how well a tool checks its own work. Look for specifics: does it run your tests, can it be restricted, does it show diffs?

Our take

Treat the two terms as separate dials. Turn the agent dial up when the work is large and checkable. Turn the review dial up when the stakes are high. The dangerous corner is a powerful agent with no review, which is vibe coding at scale.

Our own default for anything customers will touch: let the agent do the typing, keep the checks and read the diff. For the weekend project, enjoy the vibes and keep it out of production. The skill is knowing which one you are doing.

Checklist

• Decided which of the four boxes this task belongs in
• A test or check command exists and the agent runs it
• The agent produced a plan you read before it edited files
• Permissions deny secrets and protected paths
• The change lives on a branch and arrives as a diff
• A person, not the agent, approves the merge
