Just the Highlights

Cline v2

Rank #1
Open Source

The Autonomous Standard. v2 introduces 'Hive Mind', allowing multiple Cline instances to communicate across different VS Code windows to coordinate full-stack changes simultaneously.

Roo Code (Pro)

Rank #2
Open Source

The Power User's Fork. While Cline aims for simplicity, Roo Code offers 'Persona Modes' (Architect, QA, Security) that enforce strict behavior protocols. It is the preferred choice for complex system design.

Supermaven 2.0

Rank #3
$15/mo

The Context King. Now featuring a 2M token context window that sits in RAM. It predicts not just the next line, but the next *function*, often writing code before you even scroll to the empty line.

Goose (Block)

Rank #4
Open Source

The Engineering Agent. Designed to be 'unleashed' on a repo. It excels at 'dull' tasks like migration scripts, dependency bumps, and linter fixes, operating autonomously in the background.

Aider (VS Code)

Rank #5
Open Source

The Terminal Architect. The legendary CLI tool now runs as a native sidebar. Its 'Architect' mode is unbeaten for reasoning through complex refactors before touching a single line of code.

Rank #6
Open Source

The Enterprise Orchestrator. The standard for BYOM (Bring Your Own Model). It creates a unified 'Model Context Protocol' server for your entire team, ensuring everyone uses the same approved prompts and docs.

Blackbox AI Agent

Rank #7
Freemium

The Shadow Worker. Features 'CyberCoder', an agent that watches your file changes and proactively opens PRs to fix bugs or add tests for code you just wrote.

CodeGate

Rank #8
Open Source

The Security Sentinel. It doesn't write code; it polices it. Sitting between your other agents and the LLM, it aggressively filters out secrets, PII, and vulnerable patterns before they enter your editor.

Qodo Gen (Codium)

Rank #9
Freemium

The Test-Driven Agent. Unlike others that prioritize features, Qodo refuses to write code without a passing test first. It forces a TDD workflow that results in the most robust codebases.

Sourcery

Rank #10
Freemium

The Refactor Loop. It runs silently, highlighting 'code smells' and offering instant, one-click refactors to modern standards (e.g., Python 3.14 features). It keeps technical debt at zero.
