The comparison
Schedule-grade work the desktop tools can't take off Windows —
and the cloud tools can't take off their servers.
Sketchdule sits where nothing else does: the one-page milestone presentation power of a desktop scheduler, the live collaboration of a cloud app, and a privacy model neither can match — your programme stays on your device, and live sessions are end-to-end-encrypted. Hand over an editable PowerPoint or a live Excel Gantt — real objects, not a flat picture. Here's the honest, side-by-side.

Where each one is strong — and where Sketchdule wins.
Milestones Professional
The original one-page milestone presentation tool: a deep symbol and SmartColumn library, mature and detailed. It's also a Windows desktop application — a per-seat licence, no live collaboration, and your charts live on one machine.
Sketchdule brings that presentation power to any browser, adds end-to-end-encrypted real-time co-editing, and keeps your data local — no install, no licence to build.
It also matches the depth: a conditional-format rules engine, time-phased data cells, pivoted value graphs, saved report profiles, anti-collision label placement and a four-tier timescale — plus it hands over an editable PowerPoint and a live Excel Gantt of real objects, and writes your edits back to the source P6 / MS Project file, which a presentation tool can't.
Microsoft Project
A heavyweight scheduler — strong CPM, resourcing and portfolio management. But it's overkill for a board pack, the desktop edition is Windows-only, and getting a clean one-page presentation out of it is a project in itself.
Sketchdule turns a plan into a board-ready one-pager in minutes, runs anywhere, and shares without a licence or a server.
Primavera P6
The engine of record for large EPC programmes — deep CPM, resource and cost control. It is powerful and complex, server-based, and not where you build stakeholder-friendly presentations.
Sketchdule is the presentation & collaboration layer P6 lacks: open your P6 export, make it boardroom-ready, co-edit encrypted, and keep it on your device — then write the agreed dates back into the XER by activity ID.
Monday.com
A slick, general-purpose work platform — easy boards, timelines and automations for everyday PM. It isn't a project-controls scheduler (no real baselines, CPM or EVM), and everything lives on its cloud.
Sketchdule is genuinely schedule-grade — baselines, critical path, EVM and milestone presentations — and never puts your programme on someone else's servers. It also runs a real Last Planner® pull-planning board, with PPC and a constraint log, rather than a generic kanban.
OnePager
A polished PowerPoint / Project add-in for turning a plan into a reporting timeline — a mature conditional-formatting rules engine, nested swimlanes and data graphs. It's Windows- and Office-bound, per-seat and single-user, and it re-draws a source plan rather than building one.
Sketchdule matches the one-page presentation, runs in any browser for free, adds encrypted real-time collaboration — and actually schedules (CPM, float, EVM) rather than only drawing.
The depth OnePager is known for is now covered too — rules engine, nested bands, time-phased data cells, pivoted graphs, saved report profiles, and the editable-PowerPoint export that's a OnePager signature — plus a live Excel Gantt of real objects, and it pushes changes back into the source plan instead of only re-drawing it.
The short version.
- Want a polished milestone one-pager? Sketchdule does it in a browser, not a Windows install.
- Need to hand it over? Export an editable PowerPoint or a live Excel Gantt — real objects your stakeholders can tweak, not a flat picture.
- Need to collaborate live? You can — end-to-end-encrypted, with nothing stored on a server, and every change reviewed and signed off.
- Care about data privacy? Your programme physically can't reach our backend, because there isn't one.
- Already in MS Project or P6? Import the file, present and share — then write your changes back into it by activity ID. No migration, no lock-in.
- Running a Last Planner® programme? The pull-planning board, constraint log and PPC are built in, and the handoffs become real Gantt links.
“Presentation authoring, real-time collaboration, and zero-server privacy — together. No incumbent offers all three.”
