Private Cursor Alternatives for Sensitive Codebases

For most teams with sensitive code, Continue is the top pick: it works in established editors such as VS Code and JetBrains IDEs, supports self-hosted models, and lets you choose how code and prompts are processed. It is not automatically private just because you install the extension; the model provider, configuration, and telemetry settings matter. If you need an integrated editor rather than an add-on, consider a self-hosted setup built around a local model.

What to Look For

“Private” can mean several different things. Before choosing a tool, identify what must stay private: source files, prompts, generated code, repository indexes, chat history, or all of them. Then check the complete path from your editor to the model and back.

• Where inference happens: A local model runs on your machine or an organization-controlled server. A cloud model sends requests to a provider, even if the editor itself is installed locally. A self-hosted endpoint can keep inference inside your network, but requires infrastructure and maintenance.
• Data retention and training: Read the provider’s current terms for prompts, code, logs, retention, and model training. Business plans may offer different controls from consumer accounts; verify the exact plan and settings rather than assuming.
• Repository context: Code completion, chat, and multi-file edits may handle context differently. Find out whether files are indexed, where the index is stored, and whether ignored or excluded files are respected.
• Controls and auditability: Look for configurable model endpoints, telemetry controls, access management, and documentation. For regulated or highly confidential work, have security staff review the full deployment.
• Practical performance: Local inference avoids sending requests to an external model provider, but quality and speed depend on model, hardware, and context size. A smaller local model may be less capable than a hosted model.

Continue

Strengths: Continue is an open-source coding assistant available as extensions for VS Code and JetBrains IDEs. It supports different model providers and can be configured to use local models or an organization’s own inference endpoint. That flexibility makes it possible to keep model traffic within infrastructure you control, while retaining a familiar editor.

Trade-offs: Privacy depends on the configuration, not the extension alone. You must select and secure the model endpoint, review telemetry and indexing behavior, and maintain the model service if self-hosting. Local models can also require capable hardware and may not match leading hosted models on difficult tasks.

Best for: Developers who want an adaptable, editor-based workflow and have the technical support to configure a local or private model endpoint. It is a strong starting point when data boundaries matter more than a turnkey experience.

Tabby

Strengths: Tabby is an open-source, self-hosted coding assistant focused on code completion. Organizations can run its server on infrastructure they manage and connect supported editor integrations. Keeping the service under your control can make it easier to define where code context is processed.

Trade-offs: Self-hosting means operating and securing a service, managing model and hardware choices, and checking how the integration handles data. Its emphasis is narrower than an all-purpose agentic editor: evaluate whether its completion and chat capabilities cover your workflow before standardizing on it.

Best for: Teams that mainly want code completion, prefer an organization-managed deployment, and can take responsibility for infrastructure and updates.

Continue with a local model in VS Code

Strengths: Pairing Continue with a local model runner such as Ollama can keep inference on a developer workstation, subject to the tools’ current configuration and data flows. This can be useful for prototypes, offline work, or code that should not be sent to a hosted model provider. You can choose a model suited to the machine and task.

Trade-offs: “Local” does not automatically mean every feature is local. Verify that embeddings, indexing, telemetry, and any auxiliary services do not use an external provider. Model quality, speed, and context capacity vary, and every developer machine may need setup and updates.

Best for: Individual developers or small teams wanting a relatively accessible local-first experiment. For company-wide use, establish approved models and configuration rather than relying on each person to make privacy choices.

Self-hosted model gateway with your existing IDE

Strengths: Teams can use a private inference server or gateway with an existing editor extension or coding assistant that supports custom endpoints. This approach centralizes model access, authentication, and operational controls, and can keep requests on a private network. It may also let a team evaluate different models without changing everyone’s editor.

Trade-offs: This is an architecture, not a single plug-and-play product. Confirm that the editor sends all relevant requests to the configured endpoint; some features may call separate services. The organization must manage access, availability, logging, model upgrades, and endpoint security.

Best for: Security-conscious engineering organizations with platform or infrastructure staff and a need for centrally managed policies. It is usually excessive for a solo developer.

JetBrains AI Assistant with organizational controls

Strengths: Developers already using IntelliJ IDEA, PyCharm, or another JetBrains IDE may prefer its integrated assistant rather than adding a separate editor. JetBrains provides plan- and feature-dependent data-handling options; its current documentation describes controls for data use and enterprise administration. Check which models and capabilities are available under the specific subscription.

Trade-offs: An integrated commercial assistant is not the same as a fully local deployment. Available privacy controls, model routing, and retention terms can vary by plan and change over time. Do not assume that all requests remain inside your company’s network.

Best for: Teams committed to JetBrains IDEs that want a supported, integrated product and can verify that its current contractual and technical controls meet their requirements.

How to Choose

Start with the data boundary. If code must never leave a workstation, choose a verified local workflow and test every feature you intend to use. If company-controlled infrastructure is acceptable, a self-hosted model or gateway can offer centralized operation. If a cloud service is permitted under your organization’s policy, compare its current business terms and controls with the convenience it provides.

Match the tool to the work. For autocomplete, Tabby or a local completion setup may be sufficient. For chat and edits across a repository, try Continue with the exact model and indexing configuration you plan to deploy. If editor integration and administration matter more than self-hosting, investigate the controls in your current IDE’s assistant.

Set a realistic budget. Open-source software may have no license fee, but hosting, GPUs, maintenance, and staff time are real costs. Local inference may use existing hardware, though larger models can require more resources. Hosted subscriptions can be simpler to operate, but confirm the plan’s data terms and usage limits. Compare total operating cost, not just the sticker price.

Run a controlled pilot. Use a representative repository with secrets removed. Inspect network traffic and configuration with your security team, test ignored-file behavior, and confirm what is logged or retained. Measure completion quality, response time, and developer friction. Document approved models and endpoints, and repeat the review after material product or policy changes.

Frequently Asked Questions

Is a local coding assistant automatically private?
No. Check telemetry, extensions, indexing, embeddings, and any external model calls. Review the complete setup, not just where the main model runs.

Can I use a cloud model without exposing sensitive code?
Possibly, if your organization permits that provider and the relevant plan and settings meet its requirements. Verify retention, training, access, and contractual terms before sending code.

Is Continue better than Cursor?
It suits teams that value model choice and configurable deployments. Cursor may offer a more cohesive, ready-to-use experience. Which is better depends on privacy requirements, editor preference, and operational capacity.

Will local models be as capable as hosted models?
Not consistently. Results depend on the model, hardware, task, and context. Benchmark with your own non-sensitive examples before relying on a local model for complex work.

What should I check before an organization-wide rollout?
Review data flows, retention and training terms, access controls, telemetry, repository exclusions, endpoint security, and update procedures with the relevant security and legal teams.

Bottom Line

Choose Continue as the best general starting point for sensitive codebases when you want editor flexibility and the option to use local or self-hosted models. Pair it with a verified local model or private endpoint, and validate every data flow before deployment. Choose Tabby for self-hosted completion, a centrally managed gateway for organization-wide control, or an IDE-integrated commercial assistant when convenience and verified plan-specific protections matter more than running everything yourself. No tool is private by default: the deployment and provider terms determine whether it fits your codebase.
