The completion-tool showdown: Supermaven, the speed-obsessed plugin famous for near-instant suggestions, against Tabnine, the veteran that sells privacy and compliance as its headline feature. Both live inside your existing editor — neither asks you to switch.
They optimize for different things. Supermaven bets that latency is the whole game; Tabnine bets that enterprises will pay for on-premise deployment and strict data controls. This page compares them on price, privacy, and editor support using documented features and current pricing.
| Supermaven | Tabnine | |
|---|---|---|
| Pro price | $10/mo | $12/user/mo |
| Free tier | Generous — fast completions with no time limit | Basic short completions |
| Core strength | Speed — famously fast suggestions, ~1M-token context window | Privacy — zero-retention options and on-premise deployment |
| Self-hosting / on-prem | No on-premise option | Yes — self-hosted and air-gapped deployment (Enterprise) |
| Editor support | VS Code, JetBrains, Neovim | VS Code, JetBrains, Neovim, Visual Studio, Eclipse, and more |
| Training-data policy | Standard cloud terms | IP-safe training; private code never trains public models |
| Team controls | Team plan with centralized billing | SSO, policy controls, admin console (Enterprise) |
| Best for | Developers who want the fastest autocomplete in their current editor | Regulated industries and compliance-heavy teams |

Try Tabnine →Pick Supermaven if raw completion speed is what you feel every day — it is cheaper, faster, and its free tier is good enough for many developers. Pick Tabnine if compliance decides for you: on-premise deployment and strict data controls are things Supermaven simply does not offer. For everyone else, speed wins.
Supermaven was acquired by Cursor, and its completion technology now also powers Cursor's Tab feature. The standalone Supermaven plugin remains available for VS Code, JetBrains, and Neovim.
Tabnine, by a wide margin. Self-hosted and air-gapped deployment, zero-retention options, and IP-safe training are built for regulated industries. Supermaven has no on-premise offering.
Yes. Both are lightweight editor plugins, and many developers pair a fast completer like Supermaven with an agentic tool for heavier work. Check your team's policy on code-assistant tooling first.
