As a solo entrepreneur, you juggle multiple clients, projects, and deadlines. Without a good project management system, things fall through the cracks – and that damages your reputation. But most project management tools (Asana, Trello, Basecamp) charge per user, which becomes expensive if you want to collaborate with freelancers or give clients view access. Open source project management tools solve this. You self‑host them on your own VPS, add unlimited users, and pay nothing beyond your server costs.
In this post, we'll define open source project management tools, explore the best options for solo entrepreneurs, and help you choose the right one for your workflow.
ERPNext is included in every SolOPENpreneur plan – fully managed and integrated.
Start managing projects →Open source project management tools are software applications that help you plan, track, and organize tasks, projects, and resources – with the added benefit that their source code is freely available for you to use, modify, and distribute. You can install them on your own server (self‑host) and have complete control over your data, user accounts, and customizations. Unlike proprietary tools that charge per user per month, open source project management tools have no per‑user fees. You pay only for your hosting – typically a fixed monthly VPS cost – regardless of how many team members, freelancers, or clients you invite to your projects.
These tools range from simple Kanban boards to full‑featured enterprise suites that include Gantt charts, time tracking, resource management, and reporting. The best choice for you depends on the complexity of your projects and whether you need integration with other business systems like CRM and invoicing.
When you're working alone, it's tempting to keep everything in your head or in a messy notebook. But as you take on more clients and projects, that approach fails. Project management tools give you a single source of truth for all your tasks, deadlines, and communications. You can see at a glance what needs to be done today, what's overdue, and what's coming up. You can track time spent on different projects to ensure you're pricing profitably. You can share progress with clients without endless email updates. And when you eventually hire freelancers or employees, you have a system ready to onboard them. Project management isn't just about organization – it's about scaling your capacity without losing your mind.
Several excellent open source project management tools are available. Here are the top options, each suited to different needs.
ERPNext is not just a project management tool – it's a complete business management suite that includes CRM, invoicing, accounting, inventory, HR, and project management. For solo entrepreneurs who want to minimize tool sprawl, ERPNext is a powerful choice. Its project management features include task creation and assignment, Gantt charts, Kanban boards, time tracking (billable vs. non‑billable), milestone tracking, and integration with CRM and invoicing. You can also create client portals so clients can log in and see project progress. ERPNext is included in every SolOPENpreneur plan, pre‑integrated with your website, email marketing, and automation tools.
OpenProject is one of the most feature‑rich open source project management tools, used by organizations like the UN and Siemens. It includes work packages (tasks) with custom fields and workflows, Gantt charts with critical path analysis, agile boards (Scrum and Kanban), roadmaps, time and cost tracking, wikis, and meeting agendas. It's ideal if you manage complex, multi‑phase projects, but it has a steeper learning curve.
WeKan is a minimalist Trello clone. It does one thing well: organize tasks into swimlanes. Features include drag‑and‑drop boards, lists, and cards; card descriptions, checklists, due dates, and attachments; labels, comments, and mentions; custom fields; and user roles. It's very lightweight and fast, perfect for solo entrepreneurs with simple workflows or those migrating from Trello.
Taiga is designed for agile development teams, but it's flexible enough for any solo entrepreneur. It offers both Kanban and Scrum (sprint) workflows, user stories, epics, tasks, sprint planning, backlog management, custom dashboards, burn‑down charts, and GitHub/GitLab integration. It's excellent for software developers or anyone following agile methodology.
Leantime is a project management system built for non‑project managers. It simplifies agile concepts and focuses on what solopreneurs actually need: get work done. Features include Kanban boards, time tracking, goal tracking (OKRs), risk management, retrospectives, and client portals. It's user‑friendly and offers a good balance between simplicity and features.
If you also need invoicing, CRM, and accounting, choose ERPNext (included in SolOPENpreneur). If your workflow is simple – just tasks and deadlines – choose WeKan. If you build software or follow agile methodologies, choose Taiga or OpenProject. If you're non‑technical and want something simple but powerful, choose Leantime. And if you need to give clients access to see project progress, choose ERPNext or Leantime. Since SolOPENpreneur already includes ERPNext, it's the easiest starting point – you can always add another tool later if needed.
Consider a solo entrepreneur with 3 freelancers and 5 clients who need view‑only access to projects. With Asana Premium: 8 users × $13.49 = $108/month. With OpenProject self‑hosted on a VPS (already paid for): $0 extra. Over a year, that's $1,296 saved – enough to hire a virtual assistant for 50+ hours. Plus, you own your project data. No vendor can change pricing, remove features, or shut down your access.
