Free Gantt Chart for Startups
GanttFather is a free Gantt chart for startups that need to plan fast without per-seat pricing or AI paywalls. Slot-based pricing means a 20-person team and a 2-person team pay the same for the same project count. Native Model Context Protocol server lets Claude, Cursor, and other AI agents draft roadmaps and run critical-path analysis programmatically. Free tier covers 4 projects with unlimited members; paid slots from $1/month annually.
Why generic project tools fail growing startups
- Per-seat pricing scales with headcount — exactly when budget is tightest and the team is doubling.
- AI is gated behind enterprise tiers ($30+/user/month for Copilot-style add-ons) when you need it most.
- No native MCP server means agents like Claude or Cursor cannot manage your roadmap programmatically.
- Vendor lock-in: data trapped in proprietary formats (.mpp, custom JSON) makes pivots painful.
- Critical path analysis is paywalled in most tools — but founder-led teams need it to spot the next bottleneck.
What GanttFather gives startups for free
Slot-based pricing that does not punish hiring
Pay per project slot, not per seat. A 20-person team running 5 active projects costs $5/month annually — the same as a 2-person team. Hire freely without re-budgeting your project tool every quarter.
Solves: Per-seat scaling pain
Native MCP server for AI agents
GanttFather ships with a Model Context Protocol server at mcp.ganttfather.com. Connect Claude, Cursor, Windsurf, or any MCP-compatible client. Agents read tasks, manage dependencies, run critical-path analysis programmatically. No add-on fee.
Solves: AI gating pain
Critical path on the free tier
Critical path analysis is included in the free plan, not gated to a Business or Enterprise tier. Founders see the longest dependency chain and know exactly which task delay slips the launch date.
Solves: CPM paywall pain
REST API + Excel round-trip on free tier
Open data model. REST API for scripting, two-way Excel import/export for finance and stakeholder handoffs. Your project data is never trapped — export anytime, no vendor lock-in.
Solves: Vendor lock-in pain
All features unlocked on day one
Dependencies, critical path, Kanban, real-time collaboration, virtual resources, public share links, MCP/AI — every feature works on the free tier. Slots only decide how many concurrent projects you run, not which features you get.
Solves: Feature-gating pain
4 projects free, $1/month per slot annually
Free tier covers 4 concurrent projects (2 own + 2 collaborations). Need more? Each additional slot is $1/month annually ($12/year). Mix monthly + semi-annual + annual cycles, cancel any without affecting the others.
Solves: Burn-rate pain
Real startup workflows
AI-assisted roadmap planning
You are a 4-person YC startup writing a Q3 roadmap. The CTO drafts the technical spec in a doc; you need to translate that into a sequenced plan with realistic dates.
How GanttFather helps: Connect Claude Desktop to GanttFather via MCP. Paste the spec into the chat: "Create a Q3 plan with milestones, dependencies, and a 12-week timeline." The agent calls create_task repeatedly and sets dependencies via update_task. You review the draft and tighten dates — total time: 15 minutes instead of 2 hours.
Daily founder standup with AI summaries
The founders want a 60-second project status every morning without dragging the team through a 30-minute call.
How GanttFather helps: Each morning, ask the AI agent: "What is the GanttFather Q3 project status? Anything overdue or on the critical path?" The agent calls get_project_summary, get_critical_path, and list_overdue_tasks, then returns a one-paragraph summary. No meeting required.
Investor reporting via Excel export
A monthly investor update needs a snapshot of progress on every active product line.
How GanttFather helps: Export each project to Excel directly from the GanttFather UI. Drop the .xlsx files into your investor doc, or pivot the data into a custom dashboard. The export preserves task names, dates, dependencies, status, and assignees — no manual retyping.
Cross-team collaboration without per-seat fees
The 4-person team grows to 12 over a quarter. New hires need access to the roadmap from day one.
How GanttFather helps: Invite each new hire as a project member. No seat fee. Permission levels (Owner, Admin, Member, Guest) control what they can edit. Hire on Tuesday, project access live by Wednesday — same $1/month per slot, regardless of team size.
Frequently asked questions
Why slot-based pricing instead of per-seat?
Because team size at a startup is unpredictable. Per-seat pricing means every hire raises your bill. Slot-based pricing keeps the cost tied to active projects, not headcount — so a 4-person team and a 40-person team running the same 5 projects pay the same $5/month annually.
Can AI agents really manage our backlog?
Yes. The GanttFather MCP server exposes 14 tools (create_task, update_task, get_critical_path, list_overdue_tasks, etc.) that any MCP-compatible AI client can call. See /mcp for the full toolset and example workflows. Authentication is per-project, so an agent cannot accidentally modify projects outside its scope.
How does GanttFather compare to ClickUp or Notion for startups?
ClickUp is broader (docs, sprints, time tracking, chat) but its Gantt view feels secondary inside that breadth, and critical path is gated to the Business tier ($12/user/month). Notion has no native Gantt — third-party templates break under real dependencies. GanttFather is purpose-built for Gantt-first planning with all advanced features free. Compare at /vs/clickup.
Is the data exportable if we outgrow the tool?
Yes. Three exit paths: (1) Excel export preserves tasks, dates, dependencies, assignees in .xlsx; (2) REST API on the paid Enterprise tier for programmatic export; (3) MCP tools can dump full project state through any AI client. No vendor lock-in.
What is the upgrade path if we hit the 4-project limit?
Buy paid project slots from $1/month per slot annually. Each slot adds 1 project you own + 1 collaboration. Stack as many slots as you need; each is its own subscription you can cancel independently. No need to upgrade a "tier" — pricing scales linearly with active projects.
Does the free tier expire after 30 days?
No. The free tier is permanent — no trial countdown, no card required, no "upgrade in N days or lose access." 4 projects, unlimited members, all features. Forever.
