Tabnine vs GitHub Copilot
Both do inline code completion; the honest split is deployment and workflow, not a price shootout. Tabnine documents an IDE agent with SaaS and private deployment options (VPC, on-premises, including air-gapped for Enterprise), but its current standalone price and self-serve purchase path could not be verified: the official homepage and pricing route redirect to Tricentis, so check the current purchase route before deciding. GitHub Copilot individual Pro is $10 USD per month (Free: 2,000 completions per month); for training, individual plans may have interactions used for training from April 24, 2026 unless opted out, while Business and Enterprise data is not used for training under the Data Protection Agreement. Neither was measured here for suggestion quality. Choose by deployment and data-handling requirements versus GitHub ecosystem fit, not by an old price.
| Decision point | Tabnine | Github Copilot |
|---|---|---|
| Best suited to | Teams comparing IDE-based coding assistance and private deployment options against their own data-handling requirements. | Developers who want coding help in a supported editor or GitHub workflow and can review suggestions before merging. |
| 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 current comparison lists Free with limited chat/agent usage and 2,000 monthly code completions. Paid individual plans are USD $10/month (Pro), $39/month (Pro+), and $100/month (Max); monthly total credit values are $15 (Pro), $70 (Pro+), and $200 (Max), from base credits plus a flex allotment that may change. Business is $19 and Enterprise $39 USD per user per month, with pooled credits (1,900 per user on Business; 2,000 more per user on Enterprise). Agent, chat, and other AI interactions consume credits, with usage varying by model and feature. |
| 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. | AI-credit usage varies by model and feature, and plan entitlements can change. Cloud-agent changes and generated code require review, tests, and secret-handling checks. |
Use the same input
Enable each tool's completion in the same IDE on a private codebase, accept 50 suggestions each, and count how many compile without edits — while recording each vendor's stated data-retention policy.
What a successful result must preserve
Suggestions must work in a private repo, and the vendor must publish a clear data-retention policy your security team can actually read.
Evidence and test status
Pricing and feature comparison based on official pages (Tabnine agent and deployment documentation; GitHub Copilot plans and policies), observed October 2026. Older Tabnine price figures were not carried forward because the current purchase path could not be verified. We did not run a scored hands-on test; no quality ranking is claimed.
