Score: 7.3/10 (Innovation: 6, Technical: 7, Documentation: 9, Utility: 7)

OpenTab is a terminal UI that reads local records from AI coding tools like OpenCode, Claude Code, and Codex to visualize token spend, costs, and usage trends. It offers interactive drill-downs, subagent cost trees, and a self-contained HTML browser, all without backend or telemetry. Its lazygit-style exploration and read-only, standard-library approach make it a novel tool for developers managing AI costs.

Target audience: backend devs, devops, data engineers
