Start free — no Google account needed →TL;DR
Gantter requires a Google account and stores projects in Google Drive. Ganttasi works with any email address, requires no Google account, and adds Kanban boards, a multi-project dashboard, and team workload visibility that Gantter lacks — from £8/month with no per-seat pricing.
Gantter is a capable Gantt chart tool, but it's deeply tied to Google's ecosystem — you need a Google account, projects live in Google Drive, and the interface feels like a Google product from 2012. If your team doesn't use Google Workspace, or you just want a cleaner, more modern tool, Ganttasi is the natural alternative. You get the same Gantt chart capability, plus Kanban, dashboards, and team collaboration — all in a purpose-built app that works with any email address.

Gantter is locked to Google Workspace. Ganttasi works with any email address — Gmail, Outlook, or your company domain. Invite external clients without Google friction.
Gantter is timeline-only. Ganttasi lets you switch the same project between Timeline and Kanban with one click — perfect for teams that plan in Gantt and execute in Kanban.
Gantter shows one project at a time saved in Google Drive. Ganttasi's dashboard shows all your projects together — combined timeline, progress stats, and overdue alerts.
Gantter uses Google Drive permissions which can be confusing for non-Google users. Ganttasi has clean Owner / Editor / Viewer roles per project, with invite-by-email for anyone.
Gantter does one thing — Gantt charts inside Google Drive. For teams already deep in Google Workspace, that's convenient. But for everyone else, it adds unnecessary friction: you need to manage Google permissions, share Drive folders, and navigate a dated interface.
Ganttasi is a standalone tool built from scratch for modern project teams. It's clean, fast, and works with any email address. Your projects live in Ganttasi — not scattered across Drive folders. Team members get invited by email and land in a purpose-built interface, not a Google Sheet lookalike.
The free tier gives you full access to all views — Timeline, Kanban, Dashboard, and Notes — with up to 3 team members. Pro is £8/month per active user for unlimited projects and members. Viewers can join on a free account.
