Open-source project management (GPL-3.0): work packages, Gantt charts, agile boards, wiki, forums, custom fields. Free Community edition with community support; cloud or paid installation in euros excl. VAT per user per month: Basic at €5.95 (minimum 25 users), Professional at €10.95 (minimum 25), Premium at €15.95 (minimum 100), Corporate on request; month-to-month possible for Cloud Basic at €1 more per user, 2 to 5-year commitments with discounts, BIM module €1 more. Enterprise modules add email or phone support, installation help and integrations, without a feature-by-feature detail on the page.

A task list with due dates, owners and statuses, in a table and calendar view, is a realistic project for a small team. OpenProject goes further: a Gantt chart with dependencies, budgets, time tracking, agile boards. Reproducing all of it custom is a big project; reproducing what you use, often half the list, is possible. Mind the prices: the paid plans impose a minimum of 25 users, which rules out small teams.

What you lose

The Gantt chart with dependencies and critical path.
The agile boards (Scrum and Kanban).
The Enterprise modules and the vendor's support.
The built-in wiki and forums.

What a home-built tool costs once it exists

Hosting and database: a server cost, and automatic backups you actually test.
Security and GDPR: dependency updates, an HTTPS certificate, protection of your customers’ data.
Upkeep time: who fixes the tool on a Saturday night in the middle of service if the server goes down?

The prompt to build it yourself

Open in ClaudeOpen in Codex Open in Cursor

Build a small project tracker for my team, replacing a project management tool.

Context: a small agency of 6 people, 8 projects in progress, 15 to 40 tasks per project.

To do:
- Projects with an owner, start and end dates and an hours budget.
- Tasks with owner, due date, status (to do, in progress, in review, done), priority and tags.
- A Kanban board view per project and a list view filterable by person and due date.
- A simple Gantt chart showing tasks on the calendar, without dependencies.
- Time tracking per task and a total per project compared with the budget.
- Comments and attachments on each task.

Out of scope: dependencies and critical path, wiki, forums, financial budgets.

Stack: web app, PostgreSQL. README: how to run, backup.
