A detailed comparison of two popular developer tools — plus how VibeLog fits as a modern, AI-native alternative.
WakaTime automatically tracks coding time via IDE plugins. It measures time spent per project, language, file, branch, and OS — then displays it in dashboards with leaderboards and goals.
Code Time is a VS Code extension that tracks coding metrics including time, keystrokes, and lines of code. It provides flow state detection, work-life balance insights, and calendar integration.

Neither WakaTime nor Code Time was built for the era of AI-assisted coding. VibeLog is the first tool that uses MCP to integrate directly into AI coding assistants and track what they build — automatically, in real-time, with semantic detail.
Know what was added, changed, fixed, or removed — with descriptions and affected files.
Connect once via MCP. No timers, no plugins, no surveys. Code as usual.
Generate shareable reports showing exactly what was delivered. Perfect for freelancers and agencies.
The first AI-native coding session tracker. No credit card required.
