What Toggl Track actually does
Toggl Track is the leading standalone time tracking tool, founded in 2006 in Tallinn, Estonia by Krister Haav. The company is bootstrapped — no VC funding — and remains independently operated. With approximately 5M users historically claimed (current undisclosed), Toggl Track generates an estimated $32.8M ARR (GetLatka, October 2024). The product is available on web, desktop (Mac/Windows/Linux), iOS, Android, and as a browser extension.
Toggl's core value is its friction-free timer: one click starts tracking, one click stops. The browser extension and desktop app allow tracking directly from within other apps. The 100+ integrations connect Toggl to project management tools, CRMs, and invoicing software. This simplicity and breadth has made Toggl the default time tracking recommendation for freelancers and small agencies.
The pricing model creates a significant Free-to-Premium gap. Free users get basic tracking for up to 5 users, but features that most professional teams need — profit reports, timesheet approvals, labor cost tracking, and key integrations with Slack, Asana, and Jira — are all Premium ($18/user/mo) only. Starter ($9/user/mo) unlocks billable rates and project templates but still lacks profit reporting and integrations. This leaves teams in a position where they're paying $18/user/mo for what is fundamentally a simple timer with reporting.
One-click timer with manual entry
Start and stop a running timer with one click, then add project, tag, and description context. Manual time entry allows logging hours retrospectively. The timer state syncs across all devices in real-time.
Project and client categorization
Organize time entries by project, client, and task. Projects have billable rate settings and can be color-coded. Client-project hierarchies allow billing different rates for different client engagements.
Reporting and analytics
Summary, detailed, and weekly reports showing time by project, client, team member, or tag. Profit reports (billable revenue vs. labor cost) are Premium only. Reports export to CSV, PDF, and Excel.
Timesheet approvals
Weekly timesheets submitted by team members and approved by managers. Premium feature that enables payroll workflow automation and project billing accuracy.
Integrations ecosystem
100+ integrations via browser extension and native connections. Key integrations with Slack, Asana, Jira, Trello, and GitHub are Premium-only, as are the Zapier and Salesforce connections.
Cross-device timer sync with idle detection
The desktop app detects idle time (when the computer is locked or inactive) and asks whether to discard idle time from the current entry. Ensures accurate tracking without manual cleanup.

Where Toggl Track falls short
Premium-only features make Starter feel like a tease
Starter at $9/user/mo unlocks billable rates and project templates but still lacks profit reports, timesheet approvals, and key integrations. Teams that upgrade to Starter quickly discover they need Premium ($18/user/mo) for the features that matter most. Hubstaff's 2025 Toggl comparison review documents this 'you'll need Premium anyway' pattern as the top user complaint.
Free tier capped at 5 users
Toggl's free tier only supports up to 5 users — making it impractical for any team beyond a solo freelancer or very small team. Teams that grow to 6+ users must upgrade to at least Starter immediately. The 5-user cap functions as an aggressive paid conversion trigger rather than a genuine free tier.
No refunds — strict policy
Toggl's no-refund policy is documented and enforced strictly. Teams that upgrade to Premium for a project, use it for one month, then reduce team size or cancel cannot recover prorated amounts. This is particularly painful for agencies with fluctuating team sizes who upgrade for a large project and then scale back.
Inactive free accounts deleted after 6 months
Free account data is permanently deleted after 6 months of inactivity. For freelancers who use Toggl seasonally or for specific project periods, this means losing historical time data that may be needed for tax reporting, client disputes, or portfolio documentation. Toggl sends warnings, but the deletion is irreversible.
Key integrations locked behind $18/user/mo Premium
Flowace's 2025 Toggl review identifies integration lock as the second most common upgrade trigger. The Slack integration (daily summary notifications), Asana sync (time tracked per task), Jira integration (time logged to issues), and GitHub integration are all Premium-only. Teams using any of these tools must pay $18/user/mo or use manual time entry workflows.
Key features to replicate
The core feature set any Toggl Track alternative needs — plus what you can improve on.
One-click timer with cross-device sync
A running timer state stored in PostgreSQL with WebSocket or Supabase Realtime push to all active sessions. The timer shows elapsed time with 1-second precision. Starting a new timer automatically stops the previous one. A 'continue' button duplicates the last entry's context for quick restart. Cross-device sync requires the timer state to be server-authoritative — clients subscribe to timer state changes via WebSocket.
Time entry management with bulk editing
Each time entry has a start time, end time (or duration), description, project, task, tags, and billable flag. A weekly timesheet view groups entries by day. Bulk editing allows selecting multiple entries and changing project or tags simultaneously. Implement with a sortable table component (react-table) and batch API endpoints.
Project and client hierarchy with billable rates
Projects belong to clients (optional). Each project has a default hourly rate (billable rate) and a cost rate (employee labor cost). Task-level rates override project rates. A custom build stores rates in PostgreSQL with an effective-date history so historical reports reflect the rate at the time of tracking, not the current rate.
Profit reporting and labor cost analysis
Profit report = billable revenue (hours × billable rate) minus labor cost (hours × cost rate) per project. This requires both billable and cost rates per team member or project. The report is a PostgreSQL aggregation query joining time_entries, projects, and rate_schedules. This is the core Premium feature — a 1-day implementation that Toggl locks behind $18/user/mo.
Timesheet approval workflow
Weekly timesheets are submitted by team members (lock editing) and reviewed by managers (approve or reject with comments). A state machine in PostgreSQL: draft → submitted → approved/rejected. Approved timesheets trigger payroll export (CSV). Email notifications sent via Resend at each state transition.
Browser extension for in-context tracking
A Chrome/Firefox extension adds a Toggl timer button to project management tools (Asana, Jira, GitHub, Trello, Basecamp). The extension reads the page title and task name, pre-fills the timer description, and starts tracking in the Toggl context. Implement as a content script that injects a timer widget into known URLs using URL pattern matching.
Idle detection in desktop app
The desktop app (Electron) monitors system idle time using the powerMonitor API. When the user returns after N minutes of idle, a dialog asks: 'You were away for 23 minutes. Do you want to add this time or discard it?' Implementing idle detection is 1–2 days of Electron work. This feature alone justifies the desktop app for professional time trackers.
Reports with CSV/PDF export
Summary report: total time by project/client/team member in a date range. Detailed report: individual time entries with full context. Weekly report: daily breakdown per member. All three are PostgreSQL aggregation queries. PDF export uses Puppeteer server-side rendering of the report view. CSV export is a direct query result download.
Technical architecture
A Toggl Track alternative is one of the simpler SaaS products to build architecturally. The core is a time entry database with a running timer state, reporting aggregations, and a browser extension. The main technical complexity is cross-device timer sync (WebSocket or polling) and the desktop app for idle detection. Everything else is standard web infrastructure with PostgreSQL aggregations for reporting.
Frontend
Next.js App Router, React + Vite, SvelteKit
Recommended: Next.js App Router — Server Components for report rendering with fast initial load, Client Components for the live timer and time entry forms. The timer state needs a client-side WebSocket connection for cross-device sync.
Desktop app
Electron + React, Tauri + WebView, native Swift/Electron
Recommended: Electron wrapping the web app — enables code reuse between web and desktop. The idle detection feature (powerMonitor) requires Electron and is the primary reason to build a desktop app alongside the web client.
Browser extension
Chrome Extension (Manifest V3), Firefox Add-on, cross-browser extension
Recommended: Chrome Extension (Manifest V3) — inject timer buttons into Asana, Jira, GitHub, Trello, and Notion pages using content scripts. The extension communicates with the web app via the Toggl API.
Database
PostgreSQL (Supabase), MySQL, SQLite
Recommended: PostgreSQL via Supabase — time entries as indexed PostgreSQL rows (start_time, end_time indexed for fast date-range queries), JSONB for flexible tags, Realtime for live timer sync across devices.
Real-time timer sync
Supabase Realtime, WebSocket (Socket.io), Server-Sent Events
Recommended: Supabase Realtime — PostgreSQL change events trigger push to all active sessions when the timer state changes (start, stop, edit). No additional infrastructure needed.
Job queue for reports and exports
Inngest, BullMQ + Redis, Vercel Cron
Recommended: Inngest for weekly summary emails, timesheet approval reminders, and async PDF report generation. Serverless, no Redis management.
Auth and workspace management
Supabase Auth, Clerk, NextAuth v5
Recommended: Supabase Auth — workspace invitation flows, team member management, and RLS policies for workspace data isolation.
Complexity estimate
Complexity 4/10 — one of the simplest SaaS products to build. The timer, time entries, and reports are straightforward database operations. The browser extension adds 2–3 weeks but is architecturally simple. The desktop app (Electron) adds 3–4 weeks for idle detection. Total MVP: 6–10 weeks.
Toggl Track vs building your own
Open-source Toggl Track alternatives
Existing projects you can self-host or use as a starting point. Each has trade-offs.
Kimai
4.2KKimai is an open-source time tracking application (AGPL-3.0) built with Symfony (PHP) and a JavaScript frontend. It supports time entries, projects, clients, billable rates, invoicing, and team management. Actively maintained with recent releases. Self-hostable via Docker. It's the most feature-complete open-source Toggl alternative with a customer invoice generation feature that Toggl lacks.
Traggo
2.5KTraggo is a tag-based time tracking tool (MIT) built with Go and React. It uses a flexible tag-based model rather than projects and clients, making it highly customizable for unusual time tracking workflows. Self-hostable via Docker.

Breakeven vs Toggl Track
At 25 seats on Toggl Premium, the annual cost is $5,400/yr. A custom build at $25K–$60K breaks even in 5–11 months — one of the fastest breakevens in the productivity category. The economics improve further if you're an agency that can white-label the time tracker and charge clients for access: 10 clients at $50/month each generate $6,000/yr, covering hosting costs and delivering ROI from month one. The Toggl case is stronger than it appears: the build cost is low, the breakeven is fast, and the feature improvements (profit reporting, unlimited integrations, no 5-user cap) are immediately valuable.
DIY roadmap: build it yourself
This roadmap covers building a Toggl Track alternative from scratch using Next.js and Supabase. It assumes a team of 2 developers targeting a 25-seat agency deployment with custom integrations and profit reporting.
Timer and time entry core
2–3 weeks- Set up Next.js App Router project with Supabase auth and workspace isolation
- Design PostgreSQL schema: workspaces, users, clients, projects, tasks, time_entries
- Build running timer component with start/stop, Supabase Realtime cross-device sync
- Implement time entry form with project/task/tag autocomplete and duration input
- Build weekly timesheet view grouped by day with inline editing
- Add manual time entry with start/end time pickers and duration calculation
Reports, approvals, and billing
2–3 weeks- Build Summary report: time by project/client/member in date range with PostgreSQL CTEs
- Implement Profit report: billable revenue minus labor cost per project
- Add Detailed report with individual entry export to CSV and PDF (Puppeteer)
- Build timesheet approval workflow: submit/approve/reject state machine with Supabase
- Implement billable hourly rates per project with cost rates per team member
- Add invoice generation from approved timesheets with line items per project
Integrations, browser extension, and deployment
2–4 weeks- Build Chrome extension: inject timer button into Asana, Jira, GitHub, and Trello
- Add Slack integration: daily summary notifications via Slack API
- Integrate Asana API: sync time tracked to Asana task custom fields
- Build Stripe billing for workspace subscriptions
- Set up Vercel deployment with custom domain and Sentry error monitoring
- Build Electron desktop app with powerMonitor idle detection
These estimates assume 2 experienced full-stack developers. The browser extension requires separate testing across Chrome, Firefox, and Edge, plus cross-site scripting isolation for each target platform (Asana, Jira, GitHub). Budget an extra week for extension QA. Idle detection in the Electron app has macOS/Windows differences that require platform-specific testing.
Features you can't get from Toggl Track
This is where a custom build pulls ahead — features impossible or impractical on a shared platform.
Automatic time tracking from calendar events
Sync with Google Calendar and Outlook to automatically create draft time entries from scheduled meetings. The user reviews and approves calendar-derived time entries rather than starting timers manually. Toggl has no calendar auto-sync. This feature alone reduces tracking friction by 40–60% for meeting-heavy professionals.
Client-facing live time portal
Give clients a read-only portal showing live and historical time tracked against their project, with billable hours and estimated completion. Toggl's shared report links are static snapshots. A live client portal builds trust and reduces 'how much have you worked on this?' inquiries from clients.
AI-powered time entry description from productivity data
Use Claude to analyze window/app activity data (with user permission) and generate time entry descriptions automatically. 'You spent 2h in Visual Studio Code with a file named auth.ts open — log as Backend development?' Toggl's desktop app tracks window titles but doesn't use AI to generate meaningful entry descriptions.
Profitability forecasting by project
Using historical labor cost rates and tracked time, project the estimated final profitability of an ongoing engagement as work progresses. Alert project managers when a project is tracking 20% over estimated hours before the client is invoiced. Toggl has retroactive profit reports but no forward-looking forecasts.
Payroll integration for automated timesheet processing
Connect approved weekly timesheets directly to payroll providers (Gusto, ADP, Rippling) and automate the pay period timesheet submission. Toggl has no payroll integrations. This feature eliminates the manual export-import step between time tracking and payroll that most agencies do in spreadsheets.
Who should build a custom Toggl Track
Agencies with 25+ team members on billable projects
A 25-seat Toggl Premium deployment costs $5,400/yr. A custom build at $25K–$60K breaks even in 5–11 months. Agencies that need profit reporting, timesheet approvals, and deep integrations with Asana or Jira get all of these features from day one without paying Premium tier prices.
Consulting firms needing integrated invoice generation
Teams that want to embed time tracking in existing workflows
Toggl's Premium integrations require teams to pay $18/user/mo for Slack and Asana connections. A custom time tracking tool can be embedded natively in your existing project management system — time tracking as a feature of your workflow rather than a separate SaaS subscription.
Freelancers and small agencies that hit the 5-user cap
Toggl's free tier caps at 5 users and deletes inactive accounts after 6 months. A small agency that grew to 6–10 people faces an immediate $9–18/user/mo upgrade. At 10 users on Premium that's $2,160/yr — enough to justify a $25K custom build in under 12 months, especially when you add the integrations that would otherwise require Premium.

Frequently asked questions
How much does it cost to build a Toggl alternative?
Building a Toggl Track alternative costs $25K–$60K for an MVP with timer, time entries, project/client management, profit reporting, timesheet approvals, and basic integrations. A team of 2 experienced developers takes 6–10 weeks. The browser extension and Electron desktop app add $10K–$20K each if required.
How long does it take to build a Toggl clone?
6–10 weeks for an MVP with a team of 2. The timer and time entry core takes 2–3 weeks. Reports, approvals, and billing logic take 2–3 weeks. Integrations, browser extension, and deployment take 2–4 weeks. This is one of the fastest builds in the productivity category — the data model is simple and well-understood.
Are there open-source Toggl alternatives?
Two strong options: Kimai (~4.2K GitHub stars, AGPL-3.0) is the most feature-complete Toggl alternative with project management, billable rates, and invoice generation — built with PHP/Symfony. Traggo (~2.5K stars, MIT) uses a tag-based model and is built with Go + React. Kimai is the better option for agency time tracking workflows.
Can RapidDev build a custom Toggl alternative?
Yes — RapidDev has built 600+ applications including time tracking tools, billing platforms, and agency management systems. Toggl is one of the fastest builds in the productivity category at 4/10 complexity. Visit rapidevelopers.com/contact for a free estimate — most time tracker MVPs are deliverable in 6–8 weeks.
Why are Toggl's key integrations locked behind Premium?
Toggl's integration lock (Slack, Asana, Jira, GitHub behind $18/user/mo Premium) is a deliberate upsell strategy. These integrations are technically simple to build but represent the highest-value features for professional teams. By locking them to Premium, Toggl ensures teams that use project management tools must pay the highest tier — the 250% price increase from Free to Premium is justified by the integrations, not the core tracking features.
Does Toggl have a desktop app?
Yes — Toggl Track has a native desktop app for macOS, Windows, and Linux with idle detection. The desktop app is the most valuable Toggl client for professionals because idle detection ensures accurate tracking without manual cleanup. A custom build using Electron can replicate this functionality with the powerMonitor API in 3–4 days of development.
Can I import my Toggl data to a custom build?
Yes — Toggl provides full data export as CSV from the Reports section. The export includes time entry start/end times, descriptions, projects, clients, tags, and billable status. A migration script can parse the CSV and import into your custom PostgreSQL schema. Historical data integrity is well-preserved in Toggl's exports.
Is Toggl profitable as a bootstrapped company?
Toggl operates as a bootstrapped company (no VC funding) with an estimated $32.8M ARR (GetLatka, 2024). The bootstrapped model means Toggl's pricing decisions are driven by sustainable margins rather than growth-at-all-costs. This makes Toggl's pricing relatively stable but also means there's less pressure to add enterprise features — the product will likely remain in its current feature scope.
