Cody is Sourcegraph’s AI coding assistant, built on their code intelligence platform.

Overview

Type	Extension
Open Source	Partially (client)
Best For	Large codebases, enterprise code search

Key Features

• Code Graph — Deep understanding of code relationships
• Multi-Repo — Search across all your repositories
• Context Selection — Manual + automatic context
• Multiple Models — Claude, GPT, Gemini, local
• Self-Hosted — Sourcegraph Enterprise

Access Model

Cody follows Sourcegraph’s enterprise-heavy operating model. That makes it more compelling for organizations that already value code search, code intelligence, and multi-repository workflows than for casual individual use.

Code Graph Intelligence

Cody leverages Sourcegraph’s code intelligence:

You: "How is authentication handled?"

Cody (with Code Graph):
1. Finds auth-related symbols across repos
2. Traces function call paths
3. Identifies configuration files
4. Shows related tests

vs. Basic RAG:
1. Keyword search for "auth"
2. Returns potentially unrelated files

Context Control

Manually control what Cody sees:

@file:src/auth/login.ts
@repo:backend-api
@symbol:AuthService

How does login validation work?

Multi-Repository Search

For enterprise codebases:

You: "Find all usages of the PaymentService across our microservices"

Cody:
→ Searches all connected repositories
→ Shows usage patterns
→ Identifies inconsistencies
→ Suggests refactoring

Self-Hosted Setup

Sourcegraph Enterprise includes Cody:

# Docker deployment
docker run -d \
  --name sourcegraph \
  -p 7080:7080 \
  sourcegraph/server:latest

Tips

• Best value when you already use Sourcegraph
• Code Graph makes context selection much smarter
• BYOK option for data-sensitive organizations
• Multi-repo search is unique advantage
