Our verdict on Flitter

Flitter is a terminal-based split timer for speedrunners on macOS or Linux who prefer keyboard-driven run tracking. Inspired by LiveSplit, it is distributed as precompiled binaries or can be installed from source with Rust. Runners load a JSON splits file and control the timer through configurable global hotkeys. Its fit is deliberately narrow: this is a solo desktop tool for manual timing, not a broad game-tracking or leaderboard platform.

The central feature set covers the core run loop: split, undo or delete a split, pause, and reset. Flitter tracks personal bests and best segments, and highlights best splits with animated rainbow coloring. Terminal output renders at 60 FPS. The split file is human-editable, giving runners direct access to their split data rather than requiring a separate editor. The published feature set does not include auto-splitting or frame-accurate timing, so runners who need those capabilities should consider another timer.

Flitter is free and open source, with documentation and a community as support channels. Platform fit is the main constraint: macOS and Linux are supported, with the repository specifying Linux X11; Windows and Wayland are unsupported. No leaderboard integration is listed, making the product less suited to runners who want connected rankings or automated game support. Pick Flitter for lightweight, terminal-based manual timing on a supported system; choose an alternative if you need autosplits, leaderboard connections, or Windows or Wayland support.
