Tabnine vs Codeium: Which Should You Pick?

What each tool is

Tabnine describes itself in its documentation as a fully private, organization-aware AI coding agent designed to run entirely within your environment. It provides Tabnine Agent, through the CLI or the IDE, and Tabnine Chat for questions about your codebase, with plugins for VS Code, JetBrains, Visual Studio and Eclipse, plus admin analytics, team management and a configurable context engine. The documented plans are Enterprise (SaaS), which the vendor says never stores your code and is SOC 2 and GDPR compliant, and Enterprise (private installation), which runs on-premises or in a VPC. Tabnine states its models are trained exclusively on credible open source code with permissive licensing, and enterprise customers can use fine-tuned or custom models.

Codeium is the former name of the company behind Windsurf. codeium.com redirects to windsurf.com, which redirects to devin.ai/desktop, where Cognition states that Devin Desktop is the new name for Windsurf. Devin Desktop is a VS Code-derived IDE with an Agent Command Center (Spaces and a Kanban view for multiple agents), Fast Context, Supercomplete predictive completion, local agents through Devin Local, cloud agents through Devin Cloud, and an Agent Client Protocol for other agents and models. Windsurf for JetBrains continues as a separate plugin for IntelliJ IDEA, PyCharm and WebStorm.

Pricing

Tabnine does not publish prices on a page we could verify. tabnine.com/pricing redirects to a contact form on tricentis.com, and Tabnine's documentation states it cannot provide numeric pricing for each plan. The documented plans are Enterprise (SaaS) and Enterprise (private installation), with a reference to a Pro tier using universal models. For any per-seat figure, check the vendor's pricing page or contact Tricentis.

The Codeium successor is priced on devin.ai/pricing. Free is $0 with a light agent quota, limited model availability, unlimited inline edits and unlimited Tab completions. Pro is $20 a month with increased quotas, full model availability across OpenAI, Anthropic, Google and SpaceXAI plus open source models, access to Devin Cloud agents, extra usage at API pricing, and free use of SWE-2 Free in the desktop app and CLI through October 10, 2026. Max is $200 a month with significantly higher quotas. Teams is $80 a month for the team plan plus $40 a month per full developer seat, for up to 200 seats, with centralized billing, an admin dashboard with analytics and priority support. Enterprise is custom with SAML or OIDC SSO and billing in Agent Compute Units.

Where Tabnine wins

Private deployment is the whole product. Enterprise (private installation) runs on-premises or in a VPC so code and prompts stay inside your infrastructure. Devin Desktop is a cloud-connected editor; its Enterprise tier offers SSO and contract billing, but Cognition's pricing page does not describe a self-hosted or air-gapped option. If your security policy rules out a vendor cloud, only Tabnine is in the running.

Training data provenance is documented. Tabnine states its models are trained exclusively on credible open source code with permissive licensing, and that it does not train on customer code unless the customer opts in for custom models. This is a procurement answer, and it is why Tabnine still appears on shortlists in regulated industries.

Editor coverage includes Visual Studio and Eclipse. Tabnine's plugins reach VS Code, JetBrains, Visual Studio and Eclipse, which covers .NET and Java shops that a VS Code-derived desktop app plus a JetBrains plugin does not. Custom models, a configurable context engine and admin analytics all run inside the customer's environment.

Where Codeium wins

You can see the price and start today. Free costs nothing and includes unlimited Tab completions and inline edits; Pro is $20 a month; Teams and Max have published numbers. Tabnine requires a conversation with Tricentis before you know what a seat costs, and there is no self-serve individual plan.

It is an agent IDE, not an assistant. The Command Center is built for running several agents in Spaces and tracking them on a Kanban board, Devin Cloud agents are included from the Pro tier, and the Agent Client Protocol lets other agents and models connect. Tabnine has an agent in the IDE and CLI, but its product is framed around private completion and chat rather than multi-agent orchestration.

Model choice is broader. Pro lists frontier models from OpenAI, Anthropic, Google and SpaceXAI plus open source models, against Tabnine's own permissively trained models with custom models for enterprise. The desktop app also imports settings and keybindings from VS Code and Cursor, so trying it is cheap.

Who should pick which

Pick Tabnine if you are buying for an organization that cannot send code to a vendor cloud, that needs on-premises or VPC deployment, that must document training data provenance, or that standardizes on Visual Studio or Eclipse. Expect enterprise procurement, and confirm the current plan names and prices with Tricentis, because the public Tabnine pages now redirect.

Pick the Codeium successor, Devin Desktop, if you are an individual or a team that wants an agent-first editor with a free tier and a $20 Pro plan, if you want Devin Cloud agents bundled, or if you use IntelliJ, PyCharm or WebStorm and want the Windsurf for JetBrains plugin.
