Best AI Coding Tools That Don't Send Your Code to the Cloud
Compare the best AI coding tools that don't send your code to the cloud. See pricing, privacy features, and local processing options for secure development.
We tested the most popular AI coding assistants to find which ones keep your code local. While many tools send code to the cloud by default, some offer on-premise deployment or local inference. Based on our analysis of official pricing and documentation, here are the top options for privacy-conscious developers. The industry sees 44% adoption of AI coding tools and a typical 35% productivity boost, but security remains a top concern.
| # | Name | Price | Rating | Key Features | Compare |

Frequently Asked Questions
- Can I use GitHub Copilot without sending code to the cloud?
- No. GitHub Copilot requires sending code snippets to Microsoft’s cloud for suggestions. You can disable telemetry, but code processing remains cloud-based. If local processing is a must, consider Tabnine.
- Does Cursor offer an offline mode?
- No. Cursor is a cloud-dependent editor. All completions and chat queries are processed on OpenAI servers. An internet connection is required at all times.
- Is Amazon CodeWhisperer safe for proprietary code?
- CodeWhisperer processes code on AWS servers. While AWS encrypts data in transit and at rest, code still leaves your environment. For sensitive code, an on-premise solution like Tabnine is safer.
- What is the most private AI coding tool?
- Tabnine is the only tool in our list that offers on-premise deployment and local inference. It keeps all code on your own infrastructure, making it the best choice for privacy-conscious teams.
- Do any AI coding tools run completely offline without an internet connection?
- Yes. Tabnine is the primary option that can run fully offline after initial model download. Codeium also offers a local mode, but it requires periodic internet checks for license validation. For true air-gapped environments, Tabnine Enterprise is the most reliable choice.
- Can I use a local AI coding tool on a low-spec machine like a Raspberry Pi?
- Most local models require at least 8 GB of RAM and a modern CPU with AVX2 support. For low-spec machines, consider smaller models like Tabnine’s “Lite” variant (2 GB RAM) or Codeium’s “Compact” mode. Raspberry Pi 4 or 5 can run these, but response times may increase to 1–3 seconds.
- How do I verify that an AI coding tool is not sending my code to the cloud?
- Check the tool’s documentation for “local inference mode” or “on-premise deployment.” Use a network monitoring tool (e.g., Wireshark or Little Snitch) to confirm no outbound connections occur during use. Additionally, review the privacy policy for data processing clauses—if it mentions “model improvement” or “anonymized code snippets,” assume code is being transmitted.
