codex, from wherever you happen to be
Sidemesh is a small app, and a smaller companion. The app lives in your pocket. The companion sits on every machine where Codex already runs — your MacBook, a lab box, a rented VPS, that Mac mini you forgot in a closet. The two talk directly, over your own network. No pairing server. No cloud broker. No account to create.
(01) a day in the mesh
Start a Codex session at your desk. Approve a destructive edit from the train. Paste a log into a fresh prompt while you're standing in line. The session stays where you left it; you just show up.
07:42 · desk
Kick off /refactor auth module on mbp. Close the laptop. Walk to the train.
08:14 · red line, standing room only
mbp wants to git push --force-with-lease. One tap declines it. Type a one-line correction. Lock the phone.
09:05 · coffee shop
Switch to nyc-vps. Tail last night's deploy log. Start a new session to chase an error. Sip coffee.
(02) how it wires together
Every Codex machine runs a small companion that bridges the session to the phone. The mobile app holds a list of machines and speaks to each one directly — nothing in the middle.

Pairs nicely with Tailscale, a Cloudflare Tunnel, plain ssh -R, or whatever you already use to reach your boxes.

Being small means being opinionated. Here's what lives outside the scope:
