AuravsC Cline
Comparison · Cline · open-source VS Code agent

Cline is an open agent. Aura is the open engine above it.

Cline is a transparent, hackable AI agent that lives in your editor and works one task at a time. Aura is the open semantic engine above whatever agent you use: many engines in one window, a verdict on every change, and a sealed record of why.

An open VS Code agent, vs an open semantic engine with a verdict on every change.

The short version

What each one is for

C

What Cline is great at

  • Open and transparent

    Apache-licensed, bring-your-own-key, with a plan/act loop you can read and audit line by line.

  • In your editor

    Runs as a VS Code extension, so it fits the editor you already know.

  • Speaks MCP

    Connects to MCP servers and tools, so you can extend what it can reach.

What Aura adds on top

  • The layer above the agent

    Aura isn't another in-editor agent. It's the engine that reads, proves and records what any agent does on your Git.

  • Every agent, one history

    Drive several engines from one window on one shared history, instead of one extension at a time.

  • Proof and a sealed record

    A goal ↔ commit verdict plus a portable provenance record, beyond a transcript in the editor.

Reading a change
AuraAST-level semantic diff with plain-language meaning.

Honest advice

When to pick which

C

Pick Cline if…

  • You want a transparent, hackable agent inside VS Code.
  • One task at a time, bring-your-own-key, is your style.
  • You like reading exactly what the agent plans before it acts.

Pick Aura if…

  • You run several agents and want them on one history.
  • You need proof, provenance or a live team view.
  • You want the layer above whichever agent, not another editor extension.
Not either/or

Keep Cline. Add the control layer.

Cline edits; Aura remembers, proves and records. Run Cline (or any MCP agent) and let Aura read what changed, verify it against the goal, and seal the provenance.

Questions

Aura & Cline

Both are open source. What's actually different?

Different layers. Cline is an agent that edits code in your editor. Aura is the engine that tracks, proves and records what any agent does on your Git.

Can Aura work with Cline?

Yes. Aura is the layer above the editor: it reads the Git result of any agent, and connects to any MCP agent. It complements Cline, it doesn’t compete inside the editor.

Do I need to switch editors?

No. Aura sits on your Git. Keep Cline in VS Code and add the control layer around it.
