4 reasons to choose Ganty
Japanese-native — beyond translation
GanttFather supports 11 languages, but that's mostly UI translation. Ganty is built in Japan and goes deeper — Japanese holiday calendar, invoice billing, Japanese support, and local business conventions. That last mile is where it matters for Japanese teams.
In-app AI generation from one sentence
GanttFather's entry points are MCP and templates, leaning on external agents for AI. Ganty generates a full Gantt from a single sentence in-app, so PMs who never set up Claude Desktop still get AI right away.
More free projects and flat pricing
On the free tier, GanttFather allows 1 project; Ganty allows 5. Paid Ganty is flat per workspace, so cost doesn't scale with people or projects.
AI that acts — from analysis to next steps
Ganty's exact server-side computation plus AI analysis goes beyond display to detect delays and suggest fixes — aiming to tell you what to do next, in Japanese.
When GanttFather may be a better fit
For an honest comparison, here are cases where the competitor may suit you better.
When feature breadth is the top priority
If you prioritize sheer Gantt feature breadth — all dependency types (SS/FF/SF), a list view, version history, 100 templates — GanttFather is ahead in some areas today. Ganty is expanding these over time.
When MCP tool coverage is paramount
GanttFather exposes 19 MCP tools. If maximum agent-driven coverage is your priority, it's a strong option. Ganty also supports MCP on all plans, with a more focused tool set.
Migration
GanttFather supports Excel export. Import that into Ganty via 'Import from Excel'. Both tools support Excel in/out, so round-trip evaluation is easy. Task name, dates, progress, assignee, and parent are mapped automatically.
From a team that switched
“GanttFather was good, but our company needs Japanese holidays and invoice billing by default — Ganty covered those out of the box. Generating a Gantt from one Japanese sentence also landed well with non-engineers.”
