Tabnine vs CodeGeeX
Tabnine and CodeGeeX are both AI coding assistants, but they serve opposite ends of the market. Tabnine is the enterprise play: Dev at $9/user/month and Enterprise at $39/user/month (annual billing, checked October 2026), with zero code retention, SaaS/VPC/on-premise/air-gapped deployment, SSO and compliance certifications (SOC 2, GDPR, ISO 27001); it discontinued its free plan in April 2025. CodeGeeX is the free play: an open-source assistant from Zhipu AI with its CodeGeeX4-ALL-9B model on GitHub, IDE plugins for VS Code and JetBrains, code completion, translation and chat across 20+ languages, at no cost. If you need to pass a compliance audit or keep code off shared infrastructure, Tabnine is built for that. If you want capable completions without paying, CodeGeeX is the obvious first try. We did not hands-on test either product, so no quality winner is declared.
| Decision point | Tabnine | CodeGeeX |
|---|---|---|
| Best suited to | Teams comparing IDE-based coding assistance and private deployment options against their own data-handling requirements. | Individual developers and students who want a free copilot-style completion plugin |
| Plans and cost | I could not verify a current standalone Tabnine price, free tier, or trial: the official homepage and pricing route currently redirect to Tricentis. Tabnine product documentation remains accessible; check the current purchase route before selecting a plan. | The IDE plugin is listed as free for developers in its marketplace listing; a current paid tier, free quota, SLA, dedicated support, and compliance certification for the plugin/service are unconfirmed in this review. Confirm current terms on the official site before team-wide adoption. |
| Limitations | Current standalone availability and pricing could not be confirmed because the official homepage and pricing route redirect. Vendor privacy and deployment statements are documentation claims, not an independent security assessment. | Support, SLA, and compliance terms are unconfirmed from the sources captured in this review; do not assume enterprise support or certification from the plugin being free or open source. Confirm current terms on the official site before adopting team-wide. |
Use the same input
An engineering manager must pick a coding assistant for a team that handles regulated client code, while individual developers on the same team want something free for side projects.
What a successful result must preserve
The tool must satisfy the security and deployment constraints (data retention, on-premise option, SSO) first; price is secondary. For personal use, the test is whether the free tool's completions are good enough in the developer's daily languages.
Evidence and test status
Specification comparison based on Tabnine's and CodeGeeX's published pricing and feature pages plus independent 2026 pricing trackers, checked October 2026. We did not run a hands-on test on either tool; no quality winner is declared.
