The Verdict

Codeium wins on raw value for individuals and small teams thanks to its unlimited free tier and built-in chat. Tabnine is the safer bet if your organization has hard privacy requirements and wants a mature, predictable enterprise deployment. If cost is your main driver, start with Codeium free; if compliance is the driver, go straight to Tabnine's paid plans.

How to switch from Codeium to Tabnine

1Document your current Codeium setup manually — there's no export file, so record IDE extensions in use, custom settings (JSON config in VS Code/JetBrains), and any ignored directories or file-type exclusions.
2Install the Tabnine extension in each IDE your team uses (VS Code, JetBrains, Vim, or Eclipse) and sign in with a Tabnine account.
3Recreate your exclusion rules and workspace-specific settings inside Tabnine's config, since these won't transfer automatically from Codeium.
4If you relied on Codeium's chat or codebase search, test Tabnine's equivalent features early — you may need to adjust workflows since Tabnine's context features are more limited on lower tiers.
5Uninstall or disable the Codeium extension across the team's IDEs once Tabnine is confirmed working, to avoid conflicting suggestions.
6Roll out Tabnine to the full team in stages, starting with one project, and confirm licensing (Basic vs Pro vs Enterprise) covers everyone before fully cutting over.

Codeium vs Tabnine: common questions

How do I export my Codeium settings and history before switching to Tabnine?+

Codeium doesn't store a portable 'project' file — your settings live in the IDE extension config (JSON) and your chat history is tied to your Codeium account, not exportable as a standalone file. Before switching, manually note any custom keybindings, ignored file patterns, and enterprise config (if self-hosted) so you can recreate them in Tabnine's settings.

What do we lose by switching from Codeium to Tabnine?+

You'll lose Codeium's free unlimited individual tier and its integrated codebase search/chat depth — Tabnine's chat and search are more limited on lower tiers. You'll gain a stricter zero-retention privacy model and more mature enterprise controls (SSO, audit logs) if you're on Tabnine's paid plans.

Is Tabnine's free tier enough for a small team?+

Tabnine's free (Basic) tier gives basic autocomplete but lacks the private-model training and advanced context features most teams actually want. For a small team doing real production work, budget for Tabnine Pro at $9/user/month rather than relying on the free tier long-term.

Does Tabnine integrate with the same IDEs and CI tools we're already using?+

Yes — Tabnine supports VS Code, JetBrains IDEs, Vim, and Eclipse, covering most common setups, but check plugin support for any niche editor before switching. It doesn't have deep CI/CD integrations itself; it works at the IDE level, same as Codeium.

Will switching from Codeium to Tabnine cost more over time?+

For individuals, yes if you were using Codeium's free tier — Tabnine Pro starts at $9/user/month. For teams, Tabnine can be cheaper or more expensive depending on whether you need Codeium's $30/user Teams plan versus Tabnine's custom Enterprise pricing, so get a quote before committing at scale.
