GanttPeek is built for people who receive schedules but do not need to author them. It opens the useful structure without the machinery of a full project-management suite.

01

Timeline at a glance

Navigate a scalable Gantt, inspect dates and progress, follow dependency paths, and zoom the schedule without changing the source file.

Gantt timeline with tasks, milestones, dependencies, and an inspector
02

Task table that works

Search, filter status, narrow outline depth, and inspect constraints, notes, cost, progress, predecessors, and successors.

Searchable project task table
03

Resources, surfaced

Review resource names, groups, capacity, rates, and source availability fields that are present in the parsed schedule.

04

Take the answer with you

Export a paginated schedule report to PDF or the task table to CSV. The original MPP remains untouched.

02 / Private by design

Your client’s schedule
is not our dataset.

GanttPeek has no account, advertising SDK, analytics SDK, or cloud parser. The selected file is copied into a private sandbox workspace, parsed locally, and the temporary copy is removed.

03 / Compatibility

Four binary families.
Decades of schedules.

Support is determined by the MPP binary family stored in the file, not only the label on the Microsoft Project box.

What “supported” means

Core schedules—tasks, dates, durations, hierarchy, progress, dependencies, resources, basic assignments, and project properties—are covered. Password-protected files cannot be opened. Baselines, real calendar exceptions, custom fields, source critical-path flags, and some assignment details are not yet extracted and are called out inside the app. Exact Project 2021 vs 2024 vs Microsoft 365 origin cannot be distinguished because those editions share the Project 16.x / MPP14 family.

06 / Questions

Before you open the file.

Does GanttPeek edit or save MPP files?

No. It is intentionally read-only and never writes back to the selected MPP file.

Does a schedule leave my Mac?

No. Parsing happens locally in the app sandbox. GanttPeek has no upload service or analytics SDK.

Does “Project 2024 support” mean every field?

No. It means the shared Project 16.x / MPP14 binary family is accepted for the verified core schedule fields listed above. Unsupported field groups are disclosed rather than silently certified.

Can it open password-protected files?

No. Remove read protection in an authorized copy of Microsoft Project before opening the file in GanttPeek.

Is GanttPeek made by Microsoft?

No. GanttPeek is independently developed by Eutopix Labs and is not affiliated with, endorsed by, or sponsored by Microsoft.
