How Do You Use Supermaven?

Learning how to use supermaven starts with one idea: Supermaven is an AI code completion tool that suggests code as you type, and you accept a suggestion with the Tab key. This guide covers the tool with every fact checked as of November 2026, and that date matters, because Supermaven is a tool whose standalone service ended in November 2025, so this is a retrospective beginner guide, not a sales pitch for a new signup. Supermaven is not Apache Maven, the Java build tool, and it is not the IntelliJ Maven plugin, so if you came here for a pom.xml build, you want the Apache Maven documentation instead.

CodexFuse offers no Supermaven tool, so this guide teaches the real program on your own machine, not a web version of it. No Facebook promotion applies to this guide. The closest sibling guide is our GitHub Copilot beginner guide, which covers the tool most readers compare Supermaven against, and you should read it after this one if you want the live alternative.

1. Confirm the sunset status before you install, so you know what still works and what does not.
2. Install the extension for your editor from the VS Code Marketplace, the JetBrains Marketplace, or the Neovim plugin.
3. Activate it with the pop-up button, link your account, or choose the free version with an email address.
4. Open a code file and type, then watch the grey suggestion appear ahead of your cursor.
5. Press Tab to accept a suggestion, press Ctrl and the right square bracket to clear it, or press Ctrl and J to accept one word at a time.
6. Let the context window read your whole codebase, so suggestions match your project instead of one file.
7. Check the free-versus-Pro line before you pay anything, because the paid tiers are legacy prices on a sunset product.

What Is Supermaven, Exactly?

Supermaven is an AI code completion tool that runs inside your editor and suggests the next lines of code as you type, and its homepage calls it the fastest copilot, with the claim that it lets you write code 2 times faster with AI. It is an extension, not an editor, so it plugs into VS Code, JetBrains IDEs, and Neovim, and it works across more than 70 programming languages, according to the VS Code Marketplace listing. This supermaven tutorial follows the official Supermaven documentation, the VS Code Marketplace listing, and the Neovim plugin README, and it treats every vendor speed claim as the vendor's own claim, not as an independent measurement.

The mental model is simple: you type, Supermaven reads your codebase, and it offers the most likely continuation in grey text, which you accept or ignore without leaving the keyboard. The completion engine is the product, and the chat window is the extra, so the Tab lesson matters more than any other feature in this guide. Supermaven was founded by Jacob Jackson, the creator of Tabnine and a former OpenAI researcher, and it launched in public in February 2024, 989 days ago, with a 300,000-token context window that later grew to 1 million tokens.

The stars and forks are frozen historical figures, because the last code push was 7 October 2024, 36 days before the Cursor acquisition, and the 1,378 gap between stars and forks has not moved since. The repository is not archived, so the freeze is a quiet one, not a locked door, but no new code has landed in more than two years. Read the numbers as a snapshot of the launch era, not as a picture of a living project.

Is Supermaven Still Available? The Sunset Status

Supermaven is a sunset product, and its standalone service was discontinued in November 2025, according to secondary sources that include aiidelist, aiagentstore, the OpenAI Tools Hub teardown, and CB Insights, because the primary sunset notice itself was not located for this guide. Cursor, which acquired Supermaven on 12 November 2024, 725 days ago, is the named successor, and the November 2025 notice, as reported second-hand, says existing customers were refunded, agent conversations ended, and VS Code users were directed to move to Cursor. Existing Neovim and JetBrains users, the same reports say, keep receiving free autocomplete inference, so the tool is not dead for everyone, but it is not a growing product either.

The storefront complicates the story, because supermaven.com still served its full homepage and pricing page when this guide was checked, with no sunset banner visible in the fetched page text and no redirect to Cursor observed. One secondary source claims the site now redirects to Cursor, and that claim is wrong as fetched today, so do not trust a page that tells you the site is gone. The honest picture is a live-but-frozen storefront over a sunset product, and this supermaven review is written as a retrospective for that reason, not as a review of a live purchase.

The acquisition post from Cursor said the Supermaven plugin would remain maintained while Cursor became the core focus, and it named the forward path as a new Cursor Tab model built for long sequences of changes, described as tab, tab, tab. Our Cursor AI beginner guide covers the editor that acquired Supermaven, and it is the first place to look if you want the supported successor. A teardown of the acquisition reports that Cursor disclosed a 72 percent suggestion acceptance rate after the deal, and the same teardown estimates monthly recurring revenue near 80,000 dollars at exit, which was never officially disclosed.

The gaps between the milestones tell the story in one glance: 131 days passed from the public launch to version 1.0, 133 days passed from version 1.0 to the acquisition, and 264 days passed from the launch to the acquisition, so the whole independent life of the product lasted less than nine months. The last code push came 36 days before the acquisition, which means development had already slowed before the deal closed. Treat the timeline as the reason this guide is written in the past tense for the product and the present tense for the lessons.

How Do You Install Supermaven in VS Code?

A supermaven vscode install starts with one search in the Extensions tab, and the whole flow takes minutes, because the extension does the setup for you. Open VS Code, open the Extensions tab, search for Supermaven, and click Install, then watch for the Activate pop-up when the install finishes, and click Activate and follow the instructions on the Supermaven website to link your account, or click Use free version to use the Free Tier, which asks for an email address. Once it is active, you will see Supermaven Free Tier in the VS Code status bar, while Pro users see an indicator in the lower right showing the repository Supermaven is indexing.

The install needs a Supermaven account, and the account step is the same one that links the extension to your plan, so create it before you judge the suggestions. Our GitHub beginner guide covers the version-control home most readers use alongside Supermaven, and it is worth knowing how that side of your workflow works before you connect an AI tool to it. The Neovim route needs one setup call in your configuration, and it looks like this.

require("supermaven-nvim").setup({})
:SupermavenUseFree
:SupermavenStatus

How Does the Tab Lesson Work?

The Tab lesson is the whole skill, because every other feature in Supermaven is decoration around one habit: type, read the grey suggestion, and press Tab to accept it or keep typing to ignore it. The suggestion appears in grey text ahead of your cursor as you type, and it updates with every keystroke, so you never open a menu or wait for a panel. If the suggestion is wrong, keep typing and it disappears, and if it is partly right, accept one word at a time instead of the whole block.

In VS Code, the built-in autocomplete popup can cover the Supermaven suggestion, and the fix from the htmlallthethings review is to press Space and then Backspace, which clears the popup and shows the suggestion again. That trick is worth learning on day one, because the most common beginner complaint is that Supermaven never appears, when the suggestion was hidden behind the editor popup all along. No commands in this guide were executed in a live testbed, so every keybinding here is documented syntax from the official Neovim README and the VS Code Marketplace listing.

The muscle memory to build is Tab for yes, keep typing for no, and Ctrl and J for a partial yes, because accepting whole blocks blindly is how bad code enters a project. A good first week looks like this: accept short completions freely, read every multi-line completion before you accept it, and reject anything you do not understand, because the suggestion is a draft, not a review. The chat window is the second tool in the box, and it talks to GPT-4o, Claude 3.5 Sonnet, GPT-4, and other leading models, with hotkeys to view diffs, apply changes, start conversations, and switch models.

What Does the 1M-Token Context Window Do?

The context window is the amount of your codebase Supermaven can read before it suggests code, and the 1M-token context window is Pro-only, while the Free tier context size is not stated on the official page. One million tokens is roughly 3.33 times the 300,000-token window that Supermaven 1.0 replaced in July 2024, when the Babble model arrived at 2.5 times the size of the previous model. The point of a big window is simple: the model sees your whole project, your naming habits, your helper functions, and your patterns, so its suggestions match your code instead of generic examples.

Supermaven 1.0 announced 100 percent recall of the needle in a needle-in-a-haystack test, wherever the needle sat inside the 1 million tokens of context, and at that date more than 20,000 developers used Supermaven. That recall claim is a vendor claim from the 1.0 announcement, not an independent test, so read it as the company's own benchmark, not as a measured fact. In practice, the context lesson is that Supermaven shines in large, complex projects, because those projects carry the most context, and it adds the least in a single empty file with nothing to read.

The Free tier keeps your code data for 7 days, according to the official pricing page, and the code policy summary from the htmlallthethings review says code is deleted within 7 days, is not used to develop products, and is stored on AWS. Read that policy before you point Supermaven at private code, because the context window only helps if you are comfortable sending your code to the service. The Pro tier also adapts to your coding style, which is the other half of the context story: the model learns how you write, not just what you wrote.

How Do You Change Supermaven Settings?

Settings live in two places, the extension settings inside your editor and the setup table for Neovim, and the Neovim side is the documented one, with a setup call of require("supermaven-nvim").setup({}) that lets you turn off the built-in keymaps, set the suggestion colour, set the log level, or pass a condition function that disables suggestions when you want them off. The ignore_filetypes table suppresses suggestions per filetype, so a cpp entry set to true silences Supermaven in C++ files while it keeps working everywhere else. Our Neovim beginner guide covers the editor that hosts this plugin, and it is the right next read if the Neovim route is yours.

:SupermavenStart
:SupermavenStop
:SupermavenRestart
:SupermavenToggle
:SupermavenStatus
:SupermavenUseFree
:SupermavenUsePro
:SupermavenLogout
:SupermavenShowLog
:SupermavenClearLog

The commands above are the official list from the Neovim README, and the two you will use most are UseFree and UsePro, which switch the tier, and Status, which tells you whether the plugin is running. The first run prompts you for UseFree or a Pro activation link, so the tier choice happens at first launch, not in a settings page. If you use nvim-cmp, the disable_inline_completion setting turns off the inline ghost text so the completion menu owns the suggestions instead.

What Is the Free-vs-Pro Line?

Supermaven pricing starts with a free tier at 0 dollars a month, a Pro tier at 10 dollars a month, and a Team tier at 10 dollars a month per user, and those are the prices supermaven.com still displays today. The page carries a Monthly and Yearly toggle, but no yearly dollar figure appears in the extracted page text, so this guide states no annual price. Supermaven free means fast, high-quality suggestions on large codebases with 7-day data retention, and the paid tiers add the full 1M-token context window, style adaptation, the largest model, and 5 dollars a month in Supermaven Chat credits, plus a 30-day Pro trial.

The 10 dollar Pro price and the 10 dollar Team price are what the site still shows, but secondary sources that checked the pricing in June and October 2026 call them legacy prices, and they say the remaining existing-user autocomplete is free, with old paid plans no longer describing the current offer. Do not buy Pro as a fresh start in November 2026 without checking whether signup still works, because this guide did not attempt a signup and cannot confirm that a new user can still activate today. One third-party directory lists the Team tier at 15 dollars a month per user, which conflicts with the official 10 dollars, so trust the official page over the directory.

Supermaven vs GitHub Copilot: What Is Different?

Supermaven vs github copilot is the comparison most readers ask about, and the honest answer starts with price parity: Supermaven Pro costs 10 dollars a month, and GitHub Copilot Pro costs 10 dollars a month too, while Copilot Business costs 19 dollars a month per user. The products differ in shape, not in the monthly number, because Copilot is the GitHub-native assistant with pull-request summaries, issue questions, code review, Actions, chat, agents, and a command line interface, while Supermaven was the fast extension that kept your editor. Copilot also has a free tier of 2,000 completions a month, according to an October 2026 independent comparison, so the free-versus-free question is about limits, not about price alone.

The context comparison has no clean winner to quote, because Copilot does not publish one comparable context figure, and third-party estimates range from about 2,000 to about 18,000 tokens, so this guide states no single Copilot context number as fact. The speed comparison is vendor data too: Supermaven's own table claims 250 milliseconds against a leading competitor at 783 milliseconds, a gap of 533 milliseconds and a ratio of 3.13, and that table is Supermaven's own benchmark claim, not an independent measurement. The choice today is therefore simple: Copilot is the live tool with GitHub behind it, and Supermaven is the lesson in what speed and context can do, kept alive only for existing users.

What Are the Seven Mistakes Beginners Make?

The two stale guides to avoid are the aipure how-to, published 19 November 2024, 718 days ago, and the dev.to beginner tutorial, published 7 March 2025, 610 days ago, and both still quote the 300,000-token window that Supermaven 1.0 replaced in July 2024. Our Git beginner guide covers the version-control workflow that keeps bad accepted suggestions recoverable, because every accepted block lands in Git, and a quick revert beats a long debug session. The deepest mistake is not technical at all: it is treating a sunset product as a rising one, and building a workflow on a tool that has no future updates coming.

Sources

The facts in this guide come from the official Supermaven homepage and pricing page, both fetched live on 7 November 2026, the VS Code Marketplace listing for the Supermaven extension, and the official Neovim plugin repository supermaven-inc/supermaven-nvim on GitHub, including its README keymaps, settings, and command list. The repository figures are 1,456 stars, 78 forks, and 68 open issues, with the repository created on 8 May 2024 and the last code push on 7 October 2024, and the pricing figures are Free at 0 dollars, Pro at 10 dollars a month, and Team at 10 dollars a month per user, all as displayed on the official pricing page.

The sunset status comes from secondary sources, because the primary sunset notice was not located for this guide: the aiidelist review updated in June 2026, the aiagentstore comparison assessed in October 2026, the OpenAI Tools Hub teardown updated in May 2026, and CB Insights, which states that Supermaven ceased operations in November 2025. The acquisition facts come from the Cursor blog post of 12 November 2024, which announced that Supermaven was joining Cursor, and from the Bessemer portfolio page, which records the November 2024 acquisition. The version history comes from the Supermaven 1.0 announcement of 2 July 2024, which introduced the Babble model and the 1 million token context window.

The comparison facts come from the rankite comparison of AI code completion tools updated in October 2026 and the remogrid roundup of free AI code generators updated in October 2026, and the stale-guide warnings come from the aipure how-to published on 19 November 2024 and the dev.to beginner tutorial published on 7 March 2025, both of which still quote the superseded 300,000-token window. The Apache Maven disambiguation comes from the Wikipedia article on Apache Maven, which records the stable release 3.10.0 on 1 October 2026, 37 days ago, and the creation of the project by Jason van Zyl in 2002. The writer's own live verifications this run are two search snapshots, the API slug probe with live controls, the server tool registry grep, the forwarder health check, and the Python re-computation of every worked number in this guide.

Frequently Asked Questions

Is Supermaven free?

Supermaven has a free tier at 0 dollars a month with fast, high-quality suggestions on large codebases and 7-day data retention, and the official page still shows it today. The Pro tier at 10 dollars a month adds the 1M-token context window, style adaptation, the largest model, and 5 dollars a month in chat credits, with a 30-day free trial. Treat both prices as legacy figures on a sunset product, because secondary sources say the remaining existing-user autocomplete is free and the old paid plans no longer describe the current offer.

Is Supermaven the same as Apache Maven?

No, Supermaven is an AI code completion tool that suggests code inside your editor, while Apache Maven is a build automation tool used mostly for Java projects. Apache Maven works from a pom.xml file with commands like mvn clean package, and its stable release 3.10.0 arrived on 1 October 2026. The two tools share only a name, so a search for Maven setup without the words code completion will land you in Java build guides.

Does Supermaven still work in 2026?

The standalone Supermaven service was discontinued in November 2025, according to secondary sources, and VS Code users were directed to move to Cursor, which acquired Supermaven in November 2024. Existing Neovim and JetBrains users keep receiving free autocomplete inference, according to the same reports, so the tool still works for that group. A new signup was not attempted for this guide, so whether a new user can still activate today is unverified, and supermaven.com still serves its homepage and pricing page with no redirect observed.

How do I accept a Supermaven suggestion?

Press Tab to accept the full suggestion, which appears in grey text ahead of your cursor as you type. Press Ctrl and the right square bracket to clear a suggestion you do not want, or press Ctrl and J to accept it one word at a time. If the VS Code autocomplete popup covers the suggestion, press Space and then Backspace to clear the popup and see it again.

Is Supermaven better than GitHub Copilot?

Supermaven was faster on its own benchmark and offered a 1M-token context window, while Copilot is the live GitHub-native assistant with pull-request summaries, issue questions, code review, and Actions. Both Pro tiers cost 10 dollars a month, so price does not decide the comparison, and Copilot also has a free tier of 2,000 completions a month. The honest answer in November 2026 is that Copilot is the tool to adopt, and Supermaven is the tool to learn from.
