Terminal Session Recorder & Search Tool

Developers need better ways to review, debug, and understand what happened in terminal applications. This tool records TUI app sessions as searchable snapshots, lets you rewind through history, search by text/regex, and visualize frame-by-frame changes. Perfect for debugging, documentation, and demos.

Asciinema has existed for years and handles session recording well enough that most developers who want this already have a solution, which is the core tension here. The differentiation — searchable snapshots and frame-by-frame diffing — is real and solves a genuine pain point in debugging long-running TUI apps, but it's a narrow slice of an already small audience. At $1k–5k/mo, you're looking at maybe 50–200 paying developers, which is achievable but requires tight positioning around a specific workflow like debugging ncurses apps or generating TUI documentation. The biggest risk is that the target user just doesn't pay for devtools at this level of specificity — they tolerate the friction or script their own solution rather than adopt another tool in their chain.
