Why Open Source?

If you’re new to the open source world, here’s the deal. These apps are usually:

Top Open Source Project Management Apps in 2026

1. OpenProject

Best for: Engineering teams, big projects

OpenProject is a classic favorite. It’s got serious features: Gantt charts, time tracking, agile boards, and even budget tracking. It’s like a Swiss army knife for project management.

Notable features:

  • Agile and Scrum boards

2. Taiga

Taiga is fun to use and super simple to understand. Its Kanban boards are snappy and colorful. Its user interface feels more like a helpful assistant than a dusty filing cabinet.

4. Redmine

Redmine has been around forever, but it keeps evolving. Want a feature that’s not built-in? There’s probably a plugin for that—and a forum post to guide you!

Redmine lets you run multiple projects at once and track them all in one dashboard. It’s a little old-school but super versatile. In 2026, it’s lighter, faster, and packed with new themes thanks to community love.

6. Orangescrum

Best for: Remote teams juggling a lot

Orangescrum’s name may sound juicy, but the features are solid. It comes packed with options for onboarding clients, managing timesheets, and handling invoices. That makes it a good pick for agencies and freelancers.

The interface is fresh and mobile-friendly, helping you manage tasks on the go!

Includes:

  • Client and invoice management
  • Gantt charts for better planning
  • Mobile-optimized dashboard

Things to Consider Before Choosing

Not all tools are one-size-fits-all. Ask yourself the following:

  • How technical is my team? (Some tools need manual setup)
  • Are we using Agile, Scrum, or just to-do lists?
  • Will we self-host or go with cloud?

If you want total control, self-hosting may be your best bet. If you just want to get started yesterday, look for hosted versions or Docker-friendly apps.

Top Trends in 2026

A lot has changed in the world of collaborative tools. Here’s what’s hot in 2026:

  • AI-assisted planning – Auto-priority suggestions? Yes please.
  • Voice integration – Ask your PM tool to update tasks hands-free.
  • Better mobile support – More responsive UIs, offline editing, and push updates.

Final Thoughts

Managing projects shouldn’t feel like a chore. With the right open source tool, your team can work faster, smarter, and with fewer emails. The best part? You own the tool—not the other way around.

Whether you’re launching a startup, writing code, planning events, or building something totally new, there’s an open source app to help you do it better.

So go ahead—download one, test it out, and turn your chaos into clarity.
