Built on a conviction.
Powerful project management shouldn't mean handing your roadmap to someone else's servers.
The problem
Modern project tools are powerful — and they quietly cost you your data. Your roadmap, your clients, your team's work all live on someone else's servers, behind a subscription that climbs every year, with AI features that are happy to learn from your projects. You're renting access to your own plans.
The belief
It doesn't have to be that way. The tools you run your work in should run on your machine, hold their data in a file you own, and answer to you — not a billing system. Local-first isn't a nostalgic preference; for anyone handling sensitive work, it's the only honest default.
What GanttPulse is
A serious Gantt planner — drag-and-drop timeline, dependencies and critical path, allocation, baselines, exports, real-time team collaboration — with a genuine AI assistant built in. All of it runs on your own machine, and the AI runs on your own key. The capability of a modern cloud tool, without giving up the data.
Who's behind it
GanttPulse is built by Ronen Aruch, independently. No growth team chasing your engagement metrics, no investors who need your data to become the product. Just a tool made the way its maker wanted one to exist — and shipped to people who feel the same way about owning their work. Behind it sits rigor you can measure: 7,600+ automated tests, date math verified across nine timezones, and licenses that validate offline with Ed25519 — no activation server, ever.
What we stand on
You own your data
Your projects live in a file on your machine. There's no cloud of ours holding a copy, and nothing to breach.
You own your license
Buy it once. No per-seat creep, no subscription that bills you forever for a tool you already paid for.
AI on your terms
The assistant runs on your own key and your chosen provider — so you decide what it sees and where it runs.
Honest by default
We only claim what's true, and we're upfront about the one thing that leaves your machine: AI calls you opt into.
Own your projects
A planner that works for you — and keeps your work yours.
