Is Cline worth it in 2026? A detailed review
Quick Answer: Cline scores 7.7/10 in 2026. The MIT-licensed VS Code agent, released in 2024 as Claude Dev, reached 1.5M+ installs by April 2026 and runs on bring-your-own-key Claude, GPT-4, or Bedrock credentials.
Cline Review — Overall Rating: 7.7/10
Cline is an open-source AI coding agent built as a VS Code extension, originally released in 2024 by Saoud Rizwan as Claude Dev and renamed in 2025. The repository (cline/cline, MIT-licensed) reached more than 1.5 million VS Code Marketplace installs by April 2026.
Strengths
The extension is fully open-source and free, with users paying model providers directly rather than the extension vendor. Cline reads and edits files in the active workspace, runs terminal commands with explicit user approval, and pauses at human checkpoints during multi-step tasks. Bring-your-own-key support spans Anthropic, OpenAI, OpenRouter, AWS Bedrock, Google Vertex AI, and Azure, giving teams cost transparency. The MCP (Model Context Protocol) server framework lets users add custom tools for browsing, search, and external APIs without forking the project.
Weaknesses
Bring-your-own-key removes the convenience of a flat subscription: users have to set up provider accounts, manage keys, and watch token spend, which can spike on long agentic sessions. Cline does not yet match Cursor''s tightly integrated editor experience or GitHub Copilot''s deep IDE coverage across JetBrains and Visual Studio. Tasks that require browsing or external context still rely on MCP servers that users self-host.
Verdict
Cline earns 7.7/10 in 2026. Best for developers who want full transparency, open-source software, and direct control over model spend. Teams that prefer a managed subscription with no key handling are better served by Cursor or Copilot.
