Hi HN. I've been using Acpira every day for about a month. It started as a VS Code extension for my team and grew into a desktop app.

It drives the official agent CLIs (Claude Code, Codex, Antigravity, OpenCode and others) over the Agent Client Protocol. You sign in with your own subscription and the model calls stay inside each CLI. Acpira handles the UI, sessions, permission prompts and context.

What I use most:

- Summon another agent into a running session with an @ mention, or fork a session to a different agent halfway through a task.

- A built-in agent loop for any OpenAI- or Anthropic-style endpoint.

- Plugins that hot-plug. Ask an agent for a skin or a widget and it installs with one click, no restart.

The desktop app is Tauri + Rust, a 17 MB download. It runs on macOS, Windows and Linux (preview). The VS Code and IntelliJ extensions share the same Rust engine and the same sessions. iOS and Android apps that pair with the desktop engine are in testing.

Happy to answer questions, especially about how differently each CLI behaves over ACP.
