Tabnine: reviews and analysis

TLDR: Tabnine stopped competing for the lone developer and now sells to departments that have to justify where their code ends up. It installs into VS Code, the JetBrains IDEs, Visual Studio and Eclipse, and its argument is that it can run on your own infrastructure, air-gapped if needed. The published price starts at $39 per user per month on an annual subscription, with no free plan, no trial, and a button that asks for a quote.

What Tabnine is and how it works

Tabnine is one of the oldest names on this list. It was introduced on Hacker News on 6 November 2018 as predictive autocomplete that learned from your code, long before a coding assistant was an obvious product. That version was small, ran locally for many cases and did not talk: it completed. Today it does what they all do, completing as you type and holding a conversation in a side panel, with agents that touch several files.

What sets it apart is none of those features, it is where it runs. Its privacy documentation states three things in writing and they are the entire reason for its price. One, that no code is retained on their servers and that requests are processed ephemerally and discarded. Two, that your code is never used to train any of their models. Three, that you can deploy it as a hosted service, on a private cloud, on your own machines or fully air-gapped. That last case is the one almost nobody else offers, and it is incompatible with being a thin layer over somebody else’s interface: you cannot cut off from the network something that has to call outside.

The add-on installs into the editor the team already uses. The list covers VS Code, the whole JetBrains family, Visual Studio, Eclipse, Android Studio and Neovim, so nobody has to change environment. And its own models are trained only on permissively licensed code, with IP indemnification in the enterprise contract, which is the conversation a legal department wants to have before any other.

There is an important qualification on that promise. In the chat you can pick third-party models, and its own documentation warns that the privacy policies of those models may differ from theirs. So the guarantee covers the default path, not any path a developer chooses.

What it is like day to day

Here it pays to separate the software from the commercial situation, because the review record of recent months is almost entirely about the second. On the Microsoft extension marketplace it has accumulated 9.6 million installs at 4.03 across 614 ratings, and on the JetBrains one 5 million downloads at 3.58. Those are the numbers of a tool with history and with people who used it happily for years.

What has happened since is dated on those same listings and is hard reading. The manufacturer itself has renamed its VS Code add-on to legacy, and the JetBrains one carries its own notice saying it does not onboard new users to that plugin and that anyone wanting the enterprise solution should write to a sales address. Eighteen of the last twenty JetBrains reviews are two stars or fewer. One from 26 May 2026 warns the plugin is effectively dead after 28 June because all individual paid subscriptions were closed. Another, from 9 January, is written by somebody who had paid for that plan days before it became unavailable. And there are earlier criticisms that are about the product rather than the shutdown, with slow completions and imprecise answers.

That InfoWorld published a table in August 2024 with a free Basic tier and a Pro tier at $12 a month, and that the enterprise plan of the day cost exactly today’s $39, makes the story clear: there has been no price rise, there has been a withdrawal of everything below the enterprise plan. If you remember Tabnine from that era, the tool you remember is not for sale.

In real use under an enterprise contract, the experience people describe is what you would expect from a compliance-oriented product: central installation, control over which model each team uses, suggestion-acceptance metrics and the option to point everything at your own server. Nobody picks it because it completes better than its rivals. They pick it because it is the one their security department signs off.

Pricing and plans

The pricing page publishes two plans and nothing else. The entry one, Tabnine Code Assistant, from $39 per user per month on an annual subscription. The next, the agentic platform, from $59 on the same terms. There is no free plan and no trial, and both buttons say the same thing, ask for a quote, so the sale goes through a rep even though the amount is published.

There is a footnote that changes the arithmetic and deserves reading before signing. Usage is unlimited if you bring your own model, on your machines or at your own cloud endpoint. If you use the model access Tabnine provides, you add a payment for a reserved consumption quota, priced on what the model providers charge plus a five per cent handling fee. Put another way: the $39 is the licence, not necessarily the total cost of the month.

One technical detail deserves recording because it affects how this page is read: the figure sits in the code as a bare number and the dollar sign is drawn by a style rule. A person sees $39, an automated reader sees a 39 with no currency. Both independent checks in this sweep caught it separately, which is why the figure we publish is the one a person sees on opening the page.

One fact from this very week remains to be weighed. On 30 July 2026 Tricentis bought the company. The announcement says existing customers will continue to receive support for the products they use today, a formula that does not promise continued standalone sale, and the buyer states the technology will be folded into its own platform. With an acquisition four days old, any multi-year commitment deserves an exit clause.

Who it is for (and who it is not for)

It is for departments with real compliance obligations: banking, healthcare, defence, government, or any company whose code cannot leave its perimeter. If the question blocking AI adoption on your team is where the requests end up, Tabnine is one of the few answers you can take to a committee.

It is not for a developer paying out of pocket, and it no longer pretends otherwise. That profile is served by GitHub Copilot, which starts ten times lower and has a free tier, or Gemini Code Assist if the team already lives in Google Cloud. And if you want an agent working inside the editor without paying a licence, Cline and Kilo Code are free and you supply the model key. Nor is it for anyone who wants to try before talking to a person, because that door is closed.

The rest of the category is in the best AI code tools, and this particular job in IDE assistants.

Alternatives to Tabnine

The split is about buyer profile rather than features. Copilot is the comfortable standard, wired into GitHub and cheapest of the group. Gemini Code Assist fits if the company is already built on Google Cloud. Tabnine keeps the case neither of them covers, which is running inside your own infrastructure without calling anyone. They are lined up side by side in Tabnine alternatives.

Frequently Asked Questions

Does the cheap individual plan still exist?

No. It existed, and it is documented by the specialist press in August 2024 with a free basic tier and a professional one at $12 a month. Today the pricing page publishes only $39 and $59 per user per month on an annual subscription.

Can I try it before buying?

There is no published trial and no free plan, and both plans are sold by quote. If you need to evaluate before deciding, the conversation starts with a sales rep.

Can it run without an internet connection?

Yes, and that is its main argument. It can be deployed on a private cloud, on your own machines or fully air-gapped. That configuration is what justifies its price against much cheaper rivals.

Is $39 the total cost?

Not necessarily. It is the per-user licence. If you use the models Tabnine serves you add a reserved consumption quota, charged on model provider prices plus a five per cent handling fee. With your own model, usage is unlimited.

What does it mean that the plugin is legacy?

That the manufacturer has renamed the old VS Code and JetBrains extensions that way and no longer onboards new users to them. What is current are the enterprise extensions, which connect to your own Tabnine server.
