Editorial interest 82/100 Selection signal · not a rating of the site

AX lets named Claude Code, Codex CLI, Grok Build, OpenCode, and Pi sessions exchange messages through a local broker and mailbox.

Landing page captured for the 2026-09-22 issue.

For: Developers running multiple local coding-agent sessions
Worth noticing: The installer verifies SHA-256 checksums and atomically places a prebuilt binary in the user's local bin directory.

Field notes

AX uses a local broker and mailbox to connect named coding-agent sessions, with adapters for five listed harnesses. Its documentation covers more than a launch command: it explains platform requirements, saved conversations, native resume syntax, delivery failures, updates, and recovery. The installer selects a prebuilt binary, checks its SHA-256 checksum, and installs it under the current user's local bin directory.
