code-memory vs. Cloud-Based Code Intelligence

A comparison of local-first vs. cloud-dependent code intelligence tools.

The Fundamental Difference

	code-memory	Cloud Tools (Sourcegraph, Cody, Cursor)
Data Location	Your machine only	Their servers
Network Required	No (after initial setup)	Yes, always
API Key Needed	No	Yes
Code Leaves Your Machine	Never	Yes
Works Offline	Yes	No
Air-gapped Compatible	Yes	No
Telemetry	Zero	Varies

When to Choose code-memory

Ideal For:

• Proprietary codebases — Your code never leaves your machine
• Security-conscious organizations — Zero external data transmission
• Air-gapped environments — Works in completely isolated networks
• Offline development — Full functionality without internet
• Privacy-focused developers — Zero telemetry, zero tracking
• Quick setup — No accounts, no API keys, no configuration

Consider Cloud Tools If:

• You need team-wide code search across repositories
• You want cloud-based AI code generation
• Your workflow benefits from cloud sync
• You're comfortable with code being processed externally

Technical Deep Dive

How code-memory Stays Local

1. Embeddings: Uses sentence-transformers running locally on your CPU/GPU
2. Vector Search: SQLite with sqlite-vec extension — no external database
3. Code Parsing: Tree-sitter runs entirely in-process
4. Git Operations: Local git repository access only
5. Model Storage: Downloaded once to ~/.cache/huggingface/

Network Activity

code-memory network footprint:
├── Initial setup only (optional):
│   └── Model download (~600MB to local cache)
└── Runtime: ZERO network calls

Compare to cloud tools which require persistent network connections for every operation.

Air-gapped Deployment

code-memory can run in completely isolated environments:

1. Pre-download the embedding model on a connected machine
2. Transfer the model cache directory (~/.cache/huggingface/)
3. Install code-memory via offline pip or standalone binary
4. Run — no network required

See AIRGAPPED.md for detailed instructions.

Cost Comparison

	code-memory	Cloud Tools
Monetary cost	Free (MIT license)	Often subscription-based
Compute cost	Your hardware	Their infrastructure
Hidden costs	None	API usage, overages
Privacy cost	Zero	Your code on their servers

Zero Telemetry Guarantee

code-memory contains no telemetry, no analytics, no tracking code.

This isn't a configuration option — it's architectural. The codebase has:

• No HTTP clients for analytics
• No usage tracking
• No error reporting to external services
• No "phone home" functionality

You can verify this yourself by examining the source code.

Summary

Priority	Recommended Tool
Privacy & security	code-memory
Offline/air-gapped work	code-memory
Zero setup friction	code-memory
Team collaboration	Cloud tools (Sourcegraph)
Cloud AI features	Cloud tools (Cody, Cursor)

code-memory is the only option that guarantees your code stays on your machine.
