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

Cline is an excellent open-source VS Code agent with a bring-your-own-keys philosophy AIDEN shares. AIDEN adds the layer above the editor: parallel agents, a kanban board, a spec gate, and git worktrees.

Quick answer

Cline is one of the most popular open-source coding agents for VS Code: it reads your codebase, makes real edits, supports MCP, and is fully BYOK, you pay your model provider directly. AIDEN shares that philosophy but changes the form factor: instead of one agent thread inside an editor, AIDEN is a standalone desktop orchestrator running parallel Claude Code and Codex sessions, each on its own git worktree, tracked on a kanban board with an enforced spec approval gate and one-click PRs.

What AIDEN is: Desktop workspace running your Claude Code + Codex CLIs on parallel git branches
Platform: macOS 12+ (arm64 + x64), signed & notarized
Code privacy: Local, code never leaves your machine
Pricing: Free (1 project) · Solo $19/mo · Lifetime $169 · Team $10/seat

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, broad provider support including 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 like Cline's BYOK model but want orchestration above the editor: stories, spec approvals, and a worktree per story.
You want several agents running at once without juggling VS Code windows.
You want one board showing every agent, branch, and diff at a glance.
You want stories to end in a one-click PR, optionally after an LLM review pass.

A switcher's take

Cline proves the BYOK agent model works, it's free, open source, and genuinely good inside VS Code. What it can't give you is the layer above the editor: Cline has no concept of a story, a spec gate, or a branch it owns. AIDEN starts at that layer. If your unit of work is 'this file, now', stay with Cline. If it's 'these four stories this week', the board and the worktrees are the point.

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 for one project, Solo at $19/month (or $169 lifetime), and Team at $10/seat/month with a 3-seat minimum. The BYOK model is the same as Cline's, you pay your model provider directly.

Why pay $19/mo when Cline is free?

You're paying for the workspace: parallel multi-agent runs, branch-per-story automation, a kanban board, one-click PRs, and a dedicated desktop app. If those features matter for how you ship, AIDEN earns its $19/mo (or one-time $169 lifetime). If you work solo on one task at a time, Cline may be enough.
