# Helicon vs Aider

Aider is a terminal pair programmer that works in tight commit sized loops against your own API keys. Helicon is a graphical client for Meta's Muse Code CLI on your existing subscription, built for supervising longer agent threads across several repositories rather than driving one edit at a time.

## At a glance

|  | Helicon | Aider |
| --- | --- | --- |
| Interface | Desktop app and web UI | Terminal |
| Agent | Muse Code | Aider's own loop |
| Billing | Existing Muse Code subscription | Your API keys, per token |
| Working unit | A session you can resume | A git commit |
| Multi repo view | Sidebar across projects | One repo per run |
| Approvals | Queued and surfaced | Confirm in the terminal |
| License | MIT | Open source |

_Helicon compared with Aider._

## What each one is

Aider's model of work is the commit. You describe a change, it edits, it commits, you review the diff in git. That tight loop is excellent for incremental work in one repository where you want git history to be the record.

Helicon's model of work is the session. A thread can run long, spawn subagents, hit approvals and come back hours later, and the sidebar is there so you can find it again. Diffs are shown inline in the thread rather than left for git to explain.

## Where they actually differ

### Subscription versus API keys

Aider spends your API keys per token. Helicon spends nothing extra: the muse CLI uses the subscription you already hold.

### Where history lives

Aider leans on git history. Helicon keeps its own local index of projects, sessions and turns so you can reopen a conversation, not just a commit.

### Supervision

Helicon's approval queue and per thread cost are built for watching several agents at once. Aider assumes you are in the loop for each step.

## Choose Aider if

- You want git commits as the interface and the audit trail.
- You prefer a terminal and per token API billing.
- You are working in one repository at a time.

## Choose Helicon if

- You want to resume threads and read their history days later.
- You run several agents across repos and worktrees.
- Your billing is a Muse Code subscription, not API keys.

## Can you use both?

Plenty of people use a commit driven tool for small edits and an agent client for larger delegated work. They touch the same repository from different directions and do not interfere.

## Frequently asked questions

### Does Helicon commit for me?

Helicon shows what the agent changed as inline diffs. Committing is yours, and git worktrees appear as their own projects in the sidebar.

### Can Helicon use my own API key?

No. It uses the muse CLI and your `muse login`. That is the design: no second bill and no credential custody.

### Is Helicon a terminal app?

No. It is a Tauri desktop app and a web app on the same React UI, talking to a local or remote daemon.
