# Best private / local AI coding setup (2026)

> A task + requirement decision guide — not a "best AI coding tool" list. Pick by how much of your code you can keep off the cloud.

**Task:** get AI coding help without sending your source code to a vendor cloud.
**Requirements (decision dimensions):** privacy model (cloud vs self-hosted vs local) · IDE (VS Code / JetBrains / NeoVim) · model control (vendor / BYOK / local) · self-hostable · team/enterprise (solo vs compliance) · budget (free/OSS vs paid).

> ⚠️ **Not including monthly-search-volume data from our internal research index.** All traffic read here is SERP-observed + estimated. Exact monthly-search / difficulty / competition figures from our research lead's internal research index are not included. No tool accuracy numbers are fabricated.

## Decision matrix (observed capabilities)

Cells reflect public claims / SERP observation (2026-10). yes = supported, no = not supported, unverified = claim exists but untested by us.

| Tool | Self-host / local | IDE support | Model control | Keeps code private | Cost | Evidence note |
| --- | --- | --- | --- | --- | --- | --- |
| Tabby | yes (self-host) | VS Code, JetBrains, others | local model (Ollama etc.) | yes | free / OSS | OSS completion server; runs locally, code never leaves machine |
| Continue | yes (local) | VS Code, JetBrains | BYOK / local model | yes | free / OSS | OSS extension; connects Ollama / LM Studio locally |
| Cody (Sourcegraph) | enterprise self-host | VS Code, JetBrains, NeoVim | vendor + your embeddings | enterprise option | free tier + paid | Code indexing; self-host for enterprise |
| Tabnine | self-hosted / enterprise | many IDEs | vendor models, private deploy | zero-retention enterprise | free + paid | Enterprise self-host / zero-retention options claimed |
| JetBrains AI Assistant | cloud default; local completions free + Ollama | JetBrains IDEs | vendor + local endpoints | partial (cloud by default) | free local tier + sub | Free tier unlimited local completions; Ollama offline use |
| Ollama | local runtime | any (via extension) | local model | yes | free / OSS | Local model runtime behind most private setups |
| Cursor / GitHub Copilot | no (cloud) | their own editors | vendor | no (cloud) | paid | Code sent to vendor; privacy depends on plan/opt-out |

## Verdict — pick by your requirement

- **Code must never leave the machine (fully offline):** run Tabby + Ollama, or Continue pointed at a local model.
- **Enterprise compliance / zero-retention:** Tabnine self-hosted or Cody enterprise self-host — verify data-residency terms for your plan.
- **Already in JetBrains IDEs:** JetBrains AI Assistant with local completions / an Ollama endpoint avoids cloud uploads for completions.
- **Open, extensible ecosystem:** Continue extension + Ollama — you control the model and the IDE.
- **Privacy not a hard requirement:** Cursor / GitHub Copilot are faster to start but cloud-based — accept only if you're fine sending code to the vendor.

## Honesty notes

- No tool quality/accuracy percentage on this page is our own measurement. Third-party claims are explicitly marked unverified.
- "Best / recommended" means our editorial match to a stated requirement, not a claim that any external AI system will rank or cite this page.
- Monthly-search / difficulty / competition figures are not included — they require our research lead's internal research index data.
- Local-model quality vs cloud is unverified; test on your own codebase before relying on it for production.
