## Why Alera

Agentic coding is the new bottleneck of developer tooling. Most "AI IDEs" today wrap a single chat backend inside an Electron shell: slow to start, heavy on RAM, locked to one provider, and limited to one task at a time.

Alera takes the opposite bet:

- **Bring your own agent.** Alera is terminal-first. Every CLI coding agent runs in its own real PTY, the way it was meant to. No proprietary chat layer, no vendor lock-in
- **Run many agents at once.** Each task gets its own Git worktree, its own tabs, and its own terminals, so Claude, Codex, Amp, and friends can work in parallel without stepping on each other
- **Native performance.** Flutter for a fast, consistent desktop UI. Rust for the PTY and process layer (`portable_pty`). Ghostty's VTE engine for terminal parsing. No Electron, no embedded browser, no JS event loop in the hot path
- **See what your agents are doing.** Lifecycle hooks for the most popular CLI agents stream their activity into Alera so you can tell, at a glance, which terminals are idle, working, or waiting on you
- **Never lose a terminal again.** Terminal sessions persist across restarts. Close the app, reboot the machine, come back, and your scrollback, processes, and layout are still there

## Supported CLI agents

Alera works with **any CLI agent**. The agents below ship with first-class integration today (icons, managed lifecycle hooks, and live activity tracking):

Anything else that runs in a terminal (Gemini CLI, Grok, Goose, Kimi, Crush, Continue, Aider, your own scripts) works out of the box. Activity tracking is incrementally rolling out per agent.

## What you get today

Alera is in active development. These are the features shipping **right now**:

### 🗂️ Project & workspace registry

Register existing local folders or clone Git repositories from one place. Git-backed projects can spin up multiple **workspaces** backed by real Git worktrees: create a branch from a source branch or reuse an existing local branch, one task or experiment per workspace, fully isolated.

### 🌳 Worktree-native workflow

Every workspace is a worktree. Less branch juggling, fewer "wait, what was I working on?" moments. Switching contexts is instant, and your agents never collide on the same files.

### 🤖 Multi-agent terminals

Open multiple terminals per workspace, organised in tabs. Run Claude Code in one, Codex in another, Amp in
