codeseek install

# Check status
codeseek status

# Auto-index on git commits
codeseek install-hooks

Natural Language Code Search example

╰─$ codeseek search 'how the code embedding work'
1. get_embedding (0.7973)
   /home/do/ssd/iohub/dev/codeseek/rust-core/src/services/embedding_service.rs:0
2. EmbeddingService (0.2855)
   /home/do/ssd/iohub/dev/codeseek/rust-core/src/services/embedding_service.rs:0
3. EmbeddingData (0.1449)
   /home/do/ssd/iohub/dev/codeseek/rust-core/src/services/embedding_service.rs:0
4. EmbeddingResponse (0.1304)
   /home/do/ssd/iohub/dev/codeseek/rust-core/src/services/embedding_service.rs:0
5. default_model (0.0450)

Function Call Graph example

╰─$ codeseek callgraph apply_rerank
Call graph for 'apply_rerank' (depth=1):

== Callers (upstream, depth=1) ==
  search (/home/do/ssd/iohub/dev/codeseek/rust-core/src/services/hybrid_search.rs:210)

== Callees (downstream, depth=1) ==
  rerank (/home/do/ssd/iohub/dev/codeseek/rust-core/src/services/reranker_service.rs:331)
  config (/home/do/ssd/iohub/dev/codeseek/rust-core/src/services/hybrid_search.rs:325)

Install

npm

npm install -g codeseek

The npm package ships a lightweight JS wrapper that handles:

Step	Description
First-run wizard	Interactive CLI prompts for embedding API token, model, and base URL
Binary download	Automatically pulls the correct Rust binary for your platform from GitHub Releases
Pass-through	All commands (init, search, callers, etc.) are forwarded to the native binary

Supported platforms:

Platform	Architecture
macOS	arm64 (Apple Silicon), x64 (Intel)
Linux	x64

Homebrew

brew tap CodeBendKit/codeseek git@github.com:CodeBendKit/codeseek.git
brew install codeseek

From source

# install protoc
# macos: brew install protobuf
# ubuntu: sudo apt install protoc

git clone https://github.com/CodeBendKit/codeseek.git
cd codeseek
./build.sh --release

build.sh compiles both the TypeScript wrapper (dist/) and the Rust binary, then installs to ~/.codeseek/bin/.
