Beyond coding stats: what a client project really took

• Wide reach: plugins for common editors and for AI tools such as Claude Code, Codex CLI, Cursor, Copilot CLI and OpenCode, released as open source.
• Automatic: plugins send a heartbeat on activity, and WakaTime joins them into durations (by default with a 15-minute timeout). File contents are never sent.
• Detail: time per project, language, file and branch, plus goals, leaderboards and weekly reports.
• AI insights in Premium: AI adoption, model usage and spend, and AI-generated vs. human code.
• Invoices in Premium: projects from your code stats as line items, as a PDF.
• Plans: Free with one week of dashboard history, then Basic, Premium with the full history, Team and Business. Current prices are on WakaTime's pricing page.

WakaTime has an official Claude Code plugin, installed from Claude Code's plugin marketplace with your WakaTime API key. Per its README it tracks AI usage, lines of code generated and time spent prompting AI, shown on your WakaTime dashboard.

Time Momentum captures Claude Code through hooks as well, but measures differently: the active runtime of every session and subagent, tokens including cache and the cost of the session in euros, assigned to a client project.

Time Momentum is built for freelancers and agencies who do client work with AI agents.

• Effort instead of editor time: with agents, five minutes of prompting can start an hour of agent work. Time Momentum records agent runtime, tokens and cost per session, next to your own time.
• Time tracking beyond the code: parallel timers, manual entries and Stream Deck keys for calls, reviews and meetings, on the same projects.
• Clients, not only projects: effort and cost per project and client, valued in euros.
• Through to the paid invoice (Pro): orders and budgets, invoices with AI costs passed on, e-invoices, payments, outstanding balances and the margin per project.
• Operated by your agents (Pro): the tm CLI and the API do the billing work you would otherwise do by hand.

• you mainly want to understand your coding habits: languages, files, goals,
• you work in editors or AI tools Time Momentum does not capture,
• your team compares activity on leaderboards.

Prompts, responses and code never leave your machine. Time Momentum receives the model, tokens, runtime, working folder, repository and a session title, and you can switch off titles and folders or exclude single folders.
