Tabnine

You will want Tabnine if your security team has said no to every other tool: it deploys inside your own network and runs a model you host, and the agent works in the editors regulated shops actually use rather than only the fashionable ones. The daily trait that decides it is that it is allowed, which for a bank is the whole feature. Individuals and small teams should not: there is no free tier, the terms are annual, and the agent is careful rather than fast.

Pick it for compliance. Pick Claude Code if nobody is making you, and GitHub Copilot if you need something procurement has already seen.

The worst thing is that you cannot try it. There is no free plan and the terms are annual, so the evaluation happens in a sales process rather than on your own repository, and the first real run is after the signature. A careful engineer wants to see the agent fail on their code before paying a year for it, and this product does not allow that.

Insist on a paid pilot with an exit clause. What it does right: it ships for Eclipse and Visual Studio as well as VS Code and JetBrains, which nobody else on this board bothers with and which is where the regulated shops are.

No benchmark is claimed. The documented architecture is a Plan Mode the user reviews before execution, eight native tools, and a per-file approval gate, run or reject, with a diff view, so every write passes a human before it lands. This is a human-in-the-loop design that trades throughput for auditability, and it is internally consistent: nothing is verified by the agent because everything is verified by the user.

That Tabnine's own models are offered alongside frontier ones without an evaluation is the omission a buyer should ask about. The observation: the loop is honest about what it does not check.

Squeezed between Copilot's distribution and the labs' models, Tabnine retreated into compliance: enterprise-only, annual contracts, private deployment, pricing power through procurement rather than product. That is a defensible niche and a small one. Then Tricentis bought it in July 2026, and a test-automation company buys a code assistant as a place to put testing agents, not as a standalone business.

The integration is the risk: roadmaps bend toward the acquirer's customers, who write tests. Position: safe for compliance buyers, not a bet on agent quality, and read the renewal terms.

The demo is a plan and a per-file diff. Procurement is where this product lives: on-premises or air-gapped deployment, SSO, zero code retention, SOC 2 and IP indemnification, which is the whole questionnaire answered on one page. The Agentic Platform is $59 per user on an annual contract, so $3,540 a month for sixty, and the CLI gives CI a path.

The vendor changed hands this year, so legal adds a change-of-control clause and a data-migration term. Onboarding is an installer pointed at our host. Approved.

I cannot install it without a TABNINE_HOST, which means a contract, which means I have never run it: closed source with everything behind a purchase order. No free tier, no source, and a fork is a fantasy. And yet. Customer-hosted LLMs are a supported model option and MCP servers go in a plain mcpServers config with env tokens, so if someone else signs, it runs entirely inside a network I control, on a model I chose.

That is the inverse of the open tools with a cloud habit, and I notice the irony. Grudging respect, from a distance, since the distance is contractual.
