A native OWL Gantt view, no third-party library
Interactive Gantt views inside Odoo with timelines, dependencies, progress, grouping, and optional PDF export - built entirely on the Odoo web framework.
Web Gantt (technical name viin_web_gantt) is an Odoo 19.0 app for Odoo Community, built for project and service teams, operations and PMO, and Odoo implementers.
At a Glance
The facts of Web Gantt, version 0.1.2, in one place. Published by Viindoo.
Technical name
viin_web_gantt
Odoo version
19.0 (Odoo Community)
Adds
Several new Gantt-mixin models, plus extensions to base, ir.ui.view and ir.actions.act_window.view
Best for
Project and service teams; Operations and PMO; Odoo implementers
Not for
It is a view engine - what it plans depends on the module that declares the view, and it does not level resources or compute a critical path on its own.
Key features
Timeline and zoom (day/week/month/year), dependencies between records, bar colors from state or stage, grouping and parent/child hierarchy, resource overlap hints, PDF export and per-arch constraints
How It Works
The same engine, on two completely different models.
1
Project tasks
Planned start and end per task, with the dependencies between them.
2
Fleet trips
The same engine over a completely different model.
What You Get
Timeline & zoom across day, week, month, and year scales
Dependencies via a many2many field, visible on the chart
Bar colors driven by state or stage, including dynamic colors
Grouping, parent/child hierarchy, and consolidation
Resource overlap hints via an optional mixin
PDF export and per-arch scheduling constraints

What This App Does Not Do
Read this before you buy. Everything below is something the app deliberately leaves to another app or to you.
It is a view engine.
What it plans depends on the module that declares the view.
It needs start and end fields.
A record with one date is a calendar entry, not a bar.
It does not level resources.
It warns of overlap; deciding is human.
No critical path.
Dependencies are drawn, not solved.
Works Well With
Apps from the same stack, built to fit this one:
Viin Cohort View
Cohort retention analysis on the same stack.
viin_web_cohort
Who Should Use Web Gantt?
Project and service teams
Coordinate phases, milestones, and assignments with dependencies visible on one timeline.
Operations and PMO
Compare schedules across groups, export PDF snapshots for governance packs, and spot overloaded resources.
Odoo implementers
Deliver Gantt experiences on custom models using declarative XML without rebuilding a chart from scratch.
Frequently Asked Questions
What does Web Gantt do?
Interactive Gantt views inside Odoo with timelines, dependencies, progress, grouping, and optional PDF export - a native OWL Gantt view built entirely on the Odoo web framework, with no third-party Gantt library dependency.
What does Web Gantt not do?
It is a view engine. What it plans depends on the module that declares the view. It needs start and end fields. A record with one date is a calendar entry, not a bar. It does not level resources. It warns; deciding is human. No critical path. Dependencies are drawn, not solved.
Who is Web Gantt for?
Project and service teams: coordinate phases and milestones with dependencies visible on one timeline. Operations and PMO: compare schedules across groups and export PDF snapshots. Odoo implementers: deliver Gantt experiences on custom models using declarative XML.
Which Odoo version and editions does it support?
Odoo 19.0 - Odoo Community Edition. Upgrades to a newer Odoo series are a separate purchase for that series.
What does it depend on?
It installs on top of: web. Odoo installs it with the module.
How do I set it up?
Install it, then declare a viin_gantt arch on any model that exposes start, stop, and (optionally) progress, dependencies, manager, and members - or install a companion app such as Project Scheduling that already declares one for you.
What works well with it?
Project Scheduling (viin_project_gantt): the project planning built on it. Viin Fleet Operation Gantt (viin_fleet_planning_gantt): dispatch trips on the same engine. Viin Cohort View (viin_web_cohort): cohort retention analysis on the same stack.
Can I try it before buying?
Yes - the Live Preview button at the top of this page opens the module's own screen on a working database.

About Viindoo. Viindoo builds and maintains more than 1,000 apps on the Odoo App Store and runs them on Viindoo Cloud. A purchase of Web Gantt covers the 19.0 series: bug fixes on the module reach you through the store, questions go to apps.support@viindoo.com with the technical name viin_web_gantt, and moving to a newer Odoo series is a separate purchase for that series. Source code is delivered with the module and stays yours to read and adapt.
Technical Requirement
Editions: Odoo Community Edition
Depends on: the standard web module (OWL client)
Models should expose start and stop datetime fields, a default group-by field, and optionally progress, dependencies, manager, and members. Stage mode requires a status field mapping and related stage configuration including colors.
QUnit tests ship under web.qunit_suite_tests for arch parsing and view behavior.
