The only Kanban with true active lead time

Not wall-clock.
Active working
time. Big difference.

CloudByte Flow is the only Kanban tool that measures your team's true active lead time — not due dates, not wall-clock time, but actual working time with pause tracking built in. Trello, Asana, and Monday genuinely can't say that.

Features

Everything your team needs.
Nothing it doesn't.

Built for developers, designers, and product teams who care about flow state as much as task state.

⏱
True Active Lead Time Tracking
Every task tracks active working time only — not calendar time. The clock runs from In Progress all the way through Final Review, stopping only when the task is Completed. Pause when blocked, log a mandatory reason, resume when unblocked. Your lead time reflects real capacity — not waiting time in disguise.

Task Priority
Mark every task High, Medium, or Low priority. Colour-coded pills on every card, with per-column priority sorting so your most critical work always rises to the top.

Completion Criteria
Add a checklist of completion criteria to any task. A live progress bar tracks how many are done. Criteria collapse neatly on the card so your board never feels cluttered.

Multi-year Timeline
Gantt-style timeline view spanning multiple years. Tasks are grouped by state, bars show active work periods, and due date markers flag overdue items in red.

Tags & Smart Filtering
Tag tasks and filter by any combination. Multi-tag filtering across all columns and a dedicated By Tag view — instantly focus on what matters right now.

Smart Due Date Reminders
Set per-task reminders — on the due date, 1 day before, 3 days before, or a full week out. Reminders fire as browser push notifications and in-app toasts, with a persistent notification centre that stores your history and links straight back to the task.

Time-in-Stage Analytics
Go beyond total lead time. Flow measures how long each task spent specifically in In Progress and Final Review — individually. Spot exactly which stage is your bottleneck and fix it with data, not guesswork.

Dark & Light Theme
Flow defaults to a polished dark theme and lets you switch to light mode in one click from the Settings panel. Your preference is remembered across sessions — no flash, no friction.

PRO & BUSINESS
Flow AI Assistant
Ask your board anything — in plain English. The Flow AI Assistant is a built-in chat panel powered by Claude that knows your live board data in real time. Ask "which tasks are overdue?", "what is my average lead time?", "summarise my board", or "how do I share a board?" — and get an instant, specific answer. It understands your task states, priorities, due dates, pause logs, tags, criteria, and full analytics — no copy-pasting, no context-switching. Available exclusively on Pro and Business plans.

Time intelligence no one else has
Active lead time, pause tracking with reasons, blocked-time exclusion, and per-card live timers. Not available in any competing tool at any price.
💸
Flat pricing that scales fairly
While Asana, Monday and Trello charge per seat — costs that balloon fast — Flow charges per board. A 10-person team pays the same as a 2-person team.
🎯
Focused beats bloated
ClickUp and Monday do everything. Flow does one thing with surgical depth: Kanban with real measurement. No learning curve, no feature overload, no waste.

FAQ

Questions, answered.

What is lead time and why does it matter? +
Lead time is the total time from when a task is created to when it's completed. It's one of the most important metrics in software delivery — teams that track lead time consistently ship faster and with fewer surprises. CloudByte Flow measures it automatically.
Is the free plan really free forever? +
Yes. The Free plan has no time limit and no credit card required. You get 3 boards and 50 tasks per board — plenty to get started. You only upgrade when you need more.
How does real-time collaboration work? +
CloudByte Flow uses WebSocket connections (via Supabase Realtime) to sync changes instantly across all connected clients. When a teammate moves a task, you see it move in real time — no refreshing required. Important: to actively collaborate on a shared board (move cards, create tasks, edit) a teammate must hold at least a Pro account. Free-tier users invited to a shared board can view the board but cannot make edits. This keeps collaboration fair — every active team member contributes to the product they're using.
Can I export my data? +
Yes. You can export any board as a fully formatted Excel workbook (6 sheets: Summary, All Tasks, By State, Criteria, Lead Times, and a Gantt Timeline) or export all boards as JSON. Your data is always yours — no lock-in.
What are completion criteria and task priority? +
Completion criteria are a per-task checklist — define exactly what "done" means for each task. A live progress bar on the card tracks how many criteria are checked off. Task priority (High, Medium, Low) adds colour-coded pills to cards and lets you sort columns by priority so the most critical work is always visible first.
What happens if I cancel my subscription? +
You keep access until the end of your billing period. After that, your account reverts to the Free plan. Your data is never deleted — boards over the free limit become read-only until you upgrade again.
Is CloudByte Flow secure? Where is my data stored? +
All data is stored in Supabase (PostgreSQL) with row-level security. You can only access your own boards. Payments are handled entirely by Stripe — CloudByte Flow never sees your card details.
Do you offer discounts for annual plans? +
Yes — annual plans are 20% cheaper than monthly billing. Pro annual is $57.50/yr (vs $71.88/yr monthly). Business annual is $153.50/yr (vs $191.88/yr monthly). Toggle the billing switch in the pricing section above.
Can I use CloudByte Flow on mobile? +
Yes. CloudByte Flow is fully responsive with a dedicated mobile layout — fixed bottom navigation, swipeable columns, and sheet-style modals. It works great on phones and tablets.
