Recall Tmux

The log was gone. The process was still running. You needed the output, but the terminal had already moved on. That is where Recall Tmux becomes the tool you reach for without thinking.

Recall Tmux is not a plugin. It is a mode built around the standard tmux feature set, using session persistence and scrollback capture to reconstruct the state you lost. It lets you reattach to running processes and pull their scrollback, even after sessions have been detached or windows closed. No more guessing what happened between lines. No more re-running jobs just to see their logs.

At its core, Recall Tmux works by storing output in the tmux scrollback buffer. Combined with features like capture-pane, you can extract and save logs directly from any pane. It hooks into tmux’s native history limit to ensure comprehensive retrieval while keeping resource usage sane. Keyword search inside tmux or piping output to standard UNIX tools becomes instant. Split windows, multiple panes, remote sessions—Recall Tmux treats all of it as a record you can call back.

For engineers working across long-running builds, multi-step deployments, or live debugging sessions, Recall Tmux means absolute control over history. It bridges the gap between running code and permanent record. No external log stream. No fragile socket replay. Just the session itself, alive or dead, ready to be recalled.

You deploy it once. It becomes part of your workflow. The commands are a handful: tmux capture-pane -pS -history-limit to pull specific ranges, tmux save-buffer to persist data, and robust session naming to avoid conflicts. Everything else is muscle memory.

If you are done losing logs, done scrolling blind through half-dead shells, and ready to hold every byte of your session history, build Recall Tmux into your stack. See it in action now—deploy a live Recall Tmux workflow in minutes at hoop.dev.
