Agentic Extensions
Plugins for VS Code/JetBrains that turn your existing editor into an agent, capable of running terminal commands and managing git.
| Rank | Model | Price | Summary |
|---|---|---|---|
|
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. | |
|
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. | |
|
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. | |
|
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. | |
|
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. | |
|
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. | |
|
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. | |
|
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. | |
|
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. | |
|
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. |
