Hosted codebase indexing for GitHub teams
Code Indexing Tool for Codebase Indexing of Private GitHub Repos
Cursor, Copilot and most local MCP indexers build a separate index on each laptop, for the person sitting at it. That helps one developer write code. It does nothing for the QA lead, the PM or the new hire who needs to know where a rule lives. CodeIndex indexes your private GitHub repositories once, in the cloud, and gives the whole team semantic search, cited answers and an API over the same index.

Short answer
A code indexing tool parses a repository, splits the source into chunks, turns each chunk into a vector embedding and stores it so code can be found by meaning instead of exact keywords. CodeIndex is a hosted code indexing tool for GitHub: connect public or private repos, it indexes 40 file types on the branch you choose and skips vendor folders, build output and lockfiles, and everyone on the team searches or asks questions against one shared index. Plans start at $49 a month billed annually for 5 users and 10 repos.

Index every repo once, not once per laptop
When the index lives in each editor, every developer pays to build it, it goes stale the moment they switch machines, and nobody outside engineering can use it. A shared codebase index is one map of the whole system. The engineer who knows the billing service, the support lead chasing an error message and the hire on day three all ask the same index and get answers that point at the same files.
What the CodeIndex code indexing tool does
Indexing is the part nobody wants to build or babysit. These are the jobs it handles for you.
Indexes private GitHub repos
Sign in with GitHub, paste a repository URL and pick the branch. Public and private repositories are both supported, and each repo belongs to your team only.
Skips the noise
node_modules, vendor, build and dist folders, minified bundles, source maps and lockfiles are left out by default, so search results come from code your team actually wrote.
Chunks with overlap
Files are split into chunks of about 1,500 tokens with 200 tokens of overlap, so a function that crosses a chunk boundary still matches as one piece of logic.
Semantic search on top
Search for what code does, such as where expired trials get downgraded, and get ranked files with line ranges even when none of your words appear in the code.
Cited answers
Ask a question in plain English and get an explanation with links to the exact files and lines it used, in search, explain or architecture mode.
API for agents and tools
On Pro and Enterprise, your own scripts, Slack bots and AI agents query the same index over a REST API with bearer keys, instead of each one building its own.
Code indexing tools compared for a team on GitHub
Every option below indexes code. The difference is where the index lives, who can use it and what it costs to keep running.
| Cursor or Copilot editor index | Local MCP indexer | Self-hosted Sourcebot or OpenGrok | CodeIndex | |
|---|---|---|---|---|
| Where the index lives | Per developer, tied to the editor | Each laptop | Your own server | Hosted, one per team |
| Who can query it | Seat holders inside the editor | The person running it | Anyone with access to your instance | Every user on the plan, plus the API |
| Search by meaning | Yes | Yes | Sourcebot with your own LLM keys, OpenGrok no | Yes |
| Upkeep | None, but per seat | Each developer maintains it | Servers, upgrades, reindex jobs | None |
| Code hosts | Local folder | Local folder | Many | GitHub only |
| Price for 20 people | Cursor Teams $32 to $40 per seat, Copilot Business $19 per seat | Free tools, your time | Sourcebot Pro $20 per user plus hosting | $149/mo billed annually |
Cursor Teams and Copilot Business prices from public pricing pages and their June 2026 updates. Sourcebot from sourcebot.dev/pricing. CodeIndex from its pricing page, checked October 2026. CodeIndex does not index GitLab or Bitbucket and has no self-hosted edition.
How codebase indexing works in CodeIndex
-
1
Paste a GitHub URL
Use the box at the top of this page, create your account and sign in with GitHub so CodeIndex can read private repositories.
-
2
Pick a branch
Index main, develop or a release branch. CodeIndex clones it, filters out generated and vendored files and keeps files up to 1 MB.
-
3
Let it index
Files are chunked and embedded in the background. Most repositories are searchable within minutes, and you can watch progress on the repository page.
-
4
Search, ask or call the API
Invite your team, search by meaning, ask questions with cited answers and reindex after a big merge with one click or one API call.
Who buys a hosted code indexing tool
Teams with more than one repo
Once the product spans an API, a frontend, workers and shared libraries, nobody can hold the map in their head. One index across 10 to 50 repos lets people search the system instead of guessing which repo to open.
Teams where non-engineers ask about code
QA, support and product people need answers about behavior but do not have editor seats. They search and ask in the browser, and seniors stop fielding the same questions.
Teams building AI agents and bots
An agent that answers from your code needs retrieval. Pointing it at a maintained index over the API is faster than standing up chunking, embeddings and a vector store yourself.
Teams onboarding new engineers
New hires ask the index where things live and get file citations, so their first weeks go to shipping instead of reading the whole codebase.
What is code indexing and why does a team need it
Code indexing is the process of reading every file in a repository and storing it in a structure that can be searched fast. Classic indexers like ctags or OpenGrok record symbols and tokens, so you can jump to a definition or grep across a large tree. Semantic indexers go a step further and store an embedding of each chunk of code, so a search for a behavior finds the code that implements it.
A single developer gets most of that value from the index inside their editor. A team gets more from one shared index, because the questions that cost the most time come from people who do not have the code open: the engineer from another squad, the support lead, the manager writing a migration plan.
What are the best code indexing tools
The right tool depends on who will use the index. For one developer writing code, the index built into Cursor or GitHub Copilot is enough. For a team that wants to self-host and has someone to run servers, Sourcebot or OpenGrok work, and Sourcegraph covers large enterprises from $16,000 a year. For a 5 to 50 person team on GitHub that wants one hosted index everyone can search and ask, without per-seat editor licenses or infrastructure, CodeIndex is built for that case.
Is codebase indexing safe for private code
It depends on the tool, so ask three questions: where the code is stored, who can query it and whether it trains a model. In CodeIndex each repository belongs to one team, API keys only see that team's repositories, and repositories can be removed at any time. Every plan includes an audit log, kept for 7 days on Starter, 30 days on Pro and a year on Enterprise, with SSO and SAML on Enterprise.
How often should a code index be updated
Often enough that answers match what is in production. Most teams reindex after a large merge or a release, and on a schedule for busy repositories. In CodeIndex you trigger a reindex from the repository page or with one call to the reindex endpoint, so a CI job can refresh the index whenever main moves.
Frequently asked questions
What is a code indexing tool?
A code indexing tool reads a repository and stores its contents in a searchable structure. Symbol indexers record definitions and references. Semantic indexers split code into chunks and store vector embeddings, so you can search for what code does. CodeIndex is a hosted semantic code indexing tool for GitHub repositories, shared by the whole team.
How much does CodeIndex cost?
Starter is $49 a month billed annually ($99 month to month) for 5 users, 10 repos and 1,000 queries. Pro is $149 a month billed annually ($299 monthly) for 20 users, 50 repos, 10,000 queries and API access. Enterprise is $499 a month billed annually with unlimited users and repos, 30,000 queries and SSO.
Does CodeIndex index private repositories?
Yes. Sign in with GitHub to grant access, then add any public or private repository your account can read. Each repository is indexed for your team only, on the branch you choose.
Can AI agents use the code index?
Yes, through the REST API on Pro and Enterprise. An agent sends a query to the search endpoint and gets ranked snippets with file paths and line ranges, or calls the chat endpoint for a cited answer. CodeIndex does not ship an MCP server, so agents call the API directly or through a small wrapper you write.
Which languages and files does it index?
40 file extensions, including PHP, Python, Ruby, Go, Rust, Java, Kotlin, C#, C and C++, JavaScript, TypeScript, Vue and Svelte, plus SQL, GraphQL, Protobuf, YAML, JSON and Markdown. Dependency folders, build output, minified bundles and lockfiles are skipped.
Does CodeIndex support GitLab or Bitbucket?
No. CodeIndex indexes GitHub repositories only. Teams on GitLab or Bitbucket should look at Sourcegraph or a self-hosted indexer like Sourcebot.
Is there a free trial?
Yes. Every new account gets a 14-day trial with Pro features, so you can index real repositories, invite the team and test the API before the first charge.
