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.
Clockify is a general-purpose time tracking tool with browser extensions, some IDE plugins, and broad integrations. It uses manual timer-based tracking with project/task categorization.
| WakaTime | Clockify | VibeLog | |
|---|---|---|---|
| Category | Developer Time Tracker | General Time Tracker | AI Session Tracker |
| Best for | Developers wanting personal time metrics across many editors | Agencies and freelancers needing general time tracking with invoicing | Tracking what AI coding assistants build |
| Tracks what was built | No | No | Yes |
| AI awareness | None | None | Native (MCP) |
| Free tier | Yes | Yes | Yes |
| Starting price | $9/month | $3.99/user/month | $9/month |
| Developer-facing | Yes | Yes | Yes |
Neither WakaTime nor Clockify 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.
