A Toggl-like time tracking app built on Cloudflare Workers, Hono, React 19, and Shadcn UI. Runs entirely on Cloudflare's edge.

Live: https://timetracker.run

• Time tracking — one-click start/stop, projects, tasks, clients, tags, billable flags, and inline editing (including editing a running timer's elapsed time from the docked timer bar). Manual entry, a weekly timesheet grid, AI quick-add from natural language, favorites for one-click starts, and recurring entry templates that materialize on schedule.
• Timer workspace — five views behind one header: list, Toggl-style calendar (FullCalendar week/5-day/day/month), split, timesheet, and planner — with clickable untracked-gap blocks between entries.
• Calendar sync (Google + Outlook / Microsoft 365) — read-only, and both can be connected at once: events show as ghost blocks you click to track, and an optional auto-track cron converts ended meetings into entries automatically (docs/CALENDAR_SYNC.md).
• Draft your day — proposes the entries you're missing from calendar events that ended untracked, uncovered stretches in the day, and work you log on that weekday most weeks; you confirm them one card at a time, ending on a total that rescales the batch. Proposals are never counted as tracked time until confirmed.
• Budget pacing — share of budget spent, burn rate per working day, and whether the current rate overruns before the end date ("on pace to overrun by 14h · 12 working days left"). No AI — reproducible from the entries alone.
• Email digests — an opt-in morning briefing and Monday weekly summary: hours by project, budgets worth a look, anything awaiting review, and one AI-written paragraph.
• MCP connector — connect Claude, ChatGPT or any MCP client and ask about your time in plain language, or let it start timers and log entries (docs/MCP.md).
• The Assistant — deterministic nudges (untracked/current/upcoming meetings, long-running timer, empty day) plus a tool-calling chat agent (Agents SDK Durable Object over Workers AI) that can start/stop timers, log or delete entries, summarize time, and remember preferences — with human approval on every write.
• Reports — summary/weekly/detailed with grouping, rounding modes, project billing rates + currency, saved report configs, CSV/Excel/print export, and AI-drafted narrative summaries.
• Teams — invite members by email into a shared workspace (owner/admin/member roles); site-admin panel for user management.
• Real-time sync — the running timer syncs across browser tabs (and the extension) via a Durable Object WebSocket.
• Offline support — timer state is cached and mutations are queued in IndexedDB, then replayed when back online.
• Productivity tools — idle detection, not-tracking reminders, pomodoro, browser notifications (all opt-in, device-local).
• Integrations — push entries to Adobe Workfront or Microsoft Dynamics.
• Browser extension — MV3 Chrome extension: toolbar start/stop, live badge, issue/PR title pre-fill on GitHub/Jira/Linear.

See docs/USER_GUIDE.md for the full feature guide.

• Frontend: React 19, Vite, TailwindCSS v4, shadcn/ui, Zustand, TanStack Query
• Backend: Hono on Cloudflare Workers, Cloudflare D1 (SQLite), Durable Objects, Workers AI, Agents SDK, Email Service, cron triggers
• Auth: Better Auth — email/password, Google, magic link, email OTP, two-factor (TOTP), passkeys; organizations for team workspaces; bearer tokens for the extension
• Extension: MV3 Chrome extension with background service worker

pnpm workspaces + Turborepo. Versions live in the catalog: in pnpm-workspace.yaml; every root script delegates to a workspace.

apps/
  web/           @timetracker/web — SPA (src/react-app) + Hono Worker (src/worker), one Cloudflare Worker deploy; owns wrangler.jsonc, migrations/, seeds/, e2e/
  extension/     @timetracker/extension — MV3 Chrome extension (separate Vite build)
packages/
  core/          @timetracker/core — shared Zod schemas, task recurrence, brand mark (TypeScript source, no build)

Install dependencies:

pnpm install

Start the dev server (turbo runs apps/web's Vite + Cloudflare Worker together via @cloudflare/vite-plugin; pnpm dev:web skips turbo):

pnpm dev

App available at http://localhost:5173.

Secrets are loaded from apps/web/.dev.vars (copy from apps/web/.dev.vars.example):

AUTH_SECRET=<random string>   # also used to encrypt stored integration tokens

Optional calendar sync needs GOOGLE_CALENDAR_CLIENT_ID / _SECRET and/or MICROSOFT_CALENDAR_CLIENT_ID / _SECRET — see docs/CALENDAR_SYNC.md. The app runs fine without them; the feature just stays disabled.

Run the Playwright e2e suite (spins up pnpm dev against localhost:5173):

pnpm test:e2e
pnpm lint            # turbo: eslint in every workspace
pnpm typecheck       # turbo: tsc in every workspace

Git hooks (lefthook) run eslint --fix on staged files, commitlint on the message, and lint + typecheck before push.

pnpm build           # turbo: Vite bundles for apps/web + apps/extension (no typecheck)
pnpm run deploy      # turbo: build, then `wrangler deploy` from apps/web (use `run` — bare `pnpm deploy` hits pnpm's built-in)
pnpm check           # apps/web: typecheck + build + dry-run deploy (full validation)

Monitor live logs:

cd apps/web && npx wrangler tail

pnpm build:ext       # Outputs to apps/extension/dist/

Load apps/extension/dist/ as an unpacked extension in Chrome. The extension authenticates with the standard Better Auth client and the server's bearer() plugin: the popup calls signIn.email / getSession, the session token arrives in the set-auth-token response header, and it's persisted to chrome.storage.local for the background service worker (no cookies/CSRF). See apps/extension/README.md.

Cloudflare D1 (SQLite). Migrations are in apps/web/migrations/; wrangler resolves them relative to apps/web/wrangler.jsonc, so run these from apps/web:

cd apps/web

# Local
npx wrangler d1 migrations apply time-tracker --local

# Production (apply BEFORE deploying worker code that needs the new schema)
npx wrangler d1 migrations apply time-tracker --remote

Optional local sample data + demo login (never a migration — local only):

cd apps/web && npx wrangler d1 execute time-tracker --local --file=seeds/dev-seed.sql

After modifying bindings in apps/web/wrangler.jsonc:

pnpm cf-typegen      # Regenerate apps/web/worker-configuration.d.ts
