# Precise Code Navigation
Supported on [Enterprise](/pricing/plans/enterprise) plans.
Available via the Web app.
Learn and understand about Precise Code Navigation.
Precise Code Navigation is an opt-in feature that is enabled from your admin settings and requires you to upload indexes for each repository to your Sourcegraph instance. Once setup is complete on Sourcegraph, precise code navigation is available for use across popular development tools:
- On the Sourcegraph web UI
- On code files on your code host, via [integrations](/integration/)
- On diffs in your code review tool, via integrations
- Via the [Sourcegraph API](/api/graphql)
Sourcegraph automatically uses Precise Code Navigation whenever available, and Search-based Code Navigation is used as a fallback when precise navigation is not available.
Precise code navigation relies on the open source [SCIP Code Intelligence Protocol](https://github.com/sourcegraph/scip), which is a language-agnostic protocol for indexing source code.
## Setting up code navigation for your codebase
Auto-indexing is a fast way to get started, but for complex or
authenticated builds we recommend [running SCIP indexing in your CI
pipeline](/code-navigation/how-to/adding-scip-to-workflows). This reuses
your existing build configuration and secrets, delivering more reliable,
repeatable precise code navigation. For best results, verify the indexer
runs successfully on your machine first, then add it as a CI job.
1. **Manual indexing**. Index a repository and upload it to your Sourcegraph instance:
- [Index a Go repository](/code-navigation/how-to/index-a-go-repository#manual-indexing)
- [Index a TypeScript or JavaScript repository](/code-navigation/how-to/index-a-typescript-and-javascript-repository#manual-indexing)
- [Index a Java, Scala, or Kotlin repository](https://sourcegraph.github.io/scip-java/docs/getting-started.html)
- [Index a Python repository](https://sourcegraph.com/github.com/sourcegraph/scip-python)
- [Index a Ruby repository](https://sourcegraph.com/github.com/sourcegraph/scip-ruby)
2. [**Automate indexing via CI**](/code-navigation/how-to/adding-scip-to-workflows): Add indexing and uploading to your CI setup.
3. [**Auto-indexing**](/code-navigation/auto-indexing#enable-auto-indexing): Sourcegraph will automatically index your repositories and enable precise code navigation for them.
## Supported languages and indexers
Precise Code Navigation requires language-specific indexes to be generated and uploaded to your Sourcegraph instance. We currently have precise code navigation support for the languages below. See the [indexers page](/code-navigation/writing-an-indexer) for a detailed breakdown of each indexer's status.
| Language | Indexer | Status |
| ---------------------- | --------------------------------------------------------------------------------- | ---------------------- |
| Go | [scip-go](https://sourcegraph.com/github.com/sourcegraph/scip-go) | 🟢 Generally available |
| TypeScript, JavaScript | [scip-typescript](https://sourcegraph.com/github.com/sourcegraph/scip-typescript) | 🟢 Generally available |
| C, C++, CUDA | [scip-clang](https://sourcegraph.com/github.com/sourcegraph/scip-clang) | 🟢 Generally available |
| Java, Kotlin, Scala | [scip-java](https://sourcegraph.com/github.com/sourcegraph/scip-java) | 🟢 Generally available |
| Rust | [rust-analyzer](https://sourcegraph.com/github.com/rust-lang/rust-analyzer) | 🟢 Generally available |
| Python | [scip-python](https://sourcegraph.com/github.com/sourcegraph/scip-python) | 🟢 Generally available |
| Ruby | [scip-ruby](https://sourcegraph.com/github.com/sourcegraph/scip-ruby) | 🟢 Generally available |
| C#, Visual Basic | [scip-dotnet](https://github.com/sourcegraph/scip-dotnet) | 🟢 Generally available |
The easiest way to configure precise code navigation is with [auto-indexing](/code-navigation/auto-indexing). This feature uses [Sourcegraph executors](/admin/executors/) to automatically create indexes for the code, keeping precise code navigation available and up-to-date.
