Gantt Chart Pro details from its Microsoft Marketplace listing (Premium plan, 1–50 users) and teams-pro.com, checked 15 October 2026. Volume tiers above 50 users are cheaper. "Not listed" means the listing does not mention it.
Want milestones that stand out on the timeline (amber, green when done, red when overdue), subtasks assigned to teammates with in-app Teams notifications and progress that updates itself, plans shared in a channel or chat, and the option to open the same plan in a web browser outside Teams — with every feature free for 30 days before you decide.
Need finish-to-start dependencies between tasks, want to allocate resources to tasks, must export the chart to PDF or Excel, or want the lowest per-user price — especially above 50 users where its volume tiers drop to $40 and $32 per user per year.
Project Planner! gives milestones their own row on the Gantt chart as diamond markers with status colours, and tracks subtasks with assignees so the parent task's progress percentage updates automatically. Gantt Chart Pro Premium lets you flag a task as a milestone, add unlimited subtasks and set progress by hand.
Gantt Chart Pro supports finish-to-start dependencies (move a task and dependent tasks shift), resource allocation and PDF / Excel export. Project Planner! does not offer dependencies or export today; it keeps the plan simple and shared.
Project Planner! plans are scoped to a Teams channel or chat, so everyone there sees and updates the same timeline, and the same plans open in a browser at project-planner.infigen.ai/app. Gantt Chart Pro is added as a channel tab, with an owner-only or everyone-can-edit setting.
Gantt Chart Pro's free Basic version suits very small plans (Witivio lists up to 5 tasks and 3 participants), and Premium is free for the first month. Project Planner! has no permanent free plan but unlocks everything for 30 days, so you evaluate the full product.
Project Planner! starts with a 30-day free trial with all features, then $6 per user / month or $60 per user / year. Gantt Chart Pro Premium is $4.17 per user / month or $50 per user / year for 1–50 users (first month free), $40 per user / year for 51–100 users and $32 for 101–250. See current Project Planner! pricing on the home page.
Gantt Chart Pro has a free Basic version limited to a small plan (Witivio lists up to 5 tasks and 3 participants).

Project Planner! gives every feature free for 30 days, then $6 per user per month or $60 per user per year — see the pricing section.
Both add a Gantt timeline to Microsoft Teams. Gantt Chart Pro (Witivio) includes task dependencies, resource allocation and PDF/CSV export, and is slightly cheaper per user. Project Planner! focuses on milestones as first-class timeline markers, subtasks assigned to teammates with in-app Teams notifications and automatic progress, plans that live in a Teams channel or chat, and a browser app outside Teams; it has a 4.6-star Marketplace rating from 39 reviews versus 3.7 from 12 for Gantt Chart Pro.
Project Planner! shows milestones as diamond markers in their own timeline row and tracks subtasks with assignees and automatic task progress. Gantt Chart Pro Premium lets you flag a task as a milestone and add unlimited subtasks.
Not at the moment. If finish-to-start dependencies or resource allocation are essential, Gantt Chart Pro or Planner Premium cover that. Project Planner! is built for fast, shared scheduling with milestones, subtasks and team assignment inside Teams.
Gantt timelines, milestones and subtasks — shared with your whole team inside Microsoft Teams.
