Cline with a desktop workspace, not just a VS Code extension.

Cline is an excellent open-source VS Code extension for AI pair programming. AIDEN takes the same bring-your-own-keys philosophy and gives it a dedicated desktop workspace with parallel agents, a kanban board, and git worktrees.

TL;DR

Cline (5M+ installs, 61K+ GitHub stars) is the best open-source AI coding extension: it reads your codebase, makes real edits, supports MCP, and is fully BYOK — you pay your model provider directly. AIDEN shares Cline's BYOK philosophy and its commitment to real edits, not just suggestions. The difference is form factor: Cline lives inside VS Code, which means one agent thread, one file context, and no workspace-level view. AIDEN is a standalone desktop app built around multi-agent orchestration — parallel Claude Code and Codex sessions, a kanban board showing all running stories, branch-per-story automation, and auto-PRs.

Stick with Cline when

  • You live in VS Code and don't want to leave your editor.
  • You want the full Cline open-source ecosystem (custom rules, MCP, local models).
  • You prefer free and open-source tooling with no upfront cost.
  • You only run one agent task at a time.

Switch to AIDEN when

  • You want Cline's BYOK model but with a proper workspace around it.
  • You want to run multiple agent stories in parallel without multiple VS Code windows.
  • You want a kanban board showing every agent, every task, every branch.
  • You want auto-PRs and spec-driven workflow as first-class features.

A switcher's take

Cline is the best free, open-source option in the AI coding extension space and genuinely impressive for a VS Code plugin. If you're happy with one agent at a time inside VS Code, Cline is hard to beat at its price. AIDEN is the answer when you've outgrown the extension model — when you want a dedicated desktop environment where managing five stories across five branches is the default experience, not a workaround.

Cline vs AIDEN — FAQ

Can I run Cline inside AIDEN?
AIDEN uses Claude Code and Codex CLIs as its execution engines, not the Cline extension. However, many developers run Cline inside VS Code for quick single-file edits while using AIDEN for structured multi-story work.
Does AIDEN support the same models as Cline?
AIDEN routes through Claude Code (Anthropic models) and Codex CLI (OpenAI models). Cline supports a broader provider list including local models via Ollama and OpenRouter. If local model support is critical, Cline is currently ahead.
Is AIDEN open source like Cline?
AIDEN is not open source. It's a commercial desktop product with a free tier (1 project) and a $99 one-time Unlimited tier. The BYOK model is the same as Cline's — you pay your model provider directly.
Why pay $99 when Cline is free?
You're paying for the workspace: parallel multi-agent runs, branch-per-story automation, a kanban board, auto-PRs, and a dedicated desktop app. If those features matter for how you ship, AIDEN earns its $99. If you work solo on one task at a time, Cline may be enough.
