As a solo entrepreneur, juggling multiple clients, deadlines, and tasks is your daily reality. Most project management tools (Asana, Trello, Basecamp) charge per user – which is fine until you want to collaborate with freelancers or give clients view access. Suddenly your "free" tool costs $10‑$20 per extra person.
Open source project management tools flip the script. Self‑host them on your own VPS, invite unlimited users, and pay nothing beyond your server costs. Here are the top five open source project management tools for solopreneurs.
SolOPENpreneur includes ERPNext – a full ERP with project management built in.
Get organized →ERPNext isn't just a project management tool – it's a complete business management suite. But its project management module is surprisingly powerful. You get:
Best for: Solopreneurs who also need invoicing, CRM, and accounting. One tool to rule them all.
Replaces: Asana + Harvest + QuickBooks + HubSpot.
OpenProject is one of the most feature‑rich open source project management tools. It's used by organizations like the UN and Siemens. Features include:
Best for: Solopreneurs managing complex, multi‑phase projects (e.g., software development, construction, event planning).
Replaces: Jira, Microsoft Project, Asana Premium.
If you love Trello's simple Kanban boards but hate the per‑user fees, WeKan is your answer. It's a minimalist, self‑hosted Kanban board that does one thing well: organize tasks into swimlanes.
Best for: Visual thinkers, solo entrepreneurs with simple workflows, or anyone migrating from Trello.
Replaces: Trello, Monday.com (basic tier).
Taiga is designed for agile development teams, but it's flexible enough for any solo entrepreneur. It offers both Kanban and Scrum (sprint) workflows.
Best for: Solopreneurs building software products or managing creative agencies with agile methodology.
Replaces: Jira, Pivotal Tracker, Clubhouse (now Shortcut).
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.
Best for: Non‑technical solopreneurs who need a balance between simplicity and features.
Replaces: Basecamp, ClickUp, Notion (for project tracking).
If you're already using SolOPENpreneur, you get ERPNext pre‑installed. Start there – it's powerful and integrates directly with your CRM, invoicing, and support tickets. You can always add another tool later.
Consider a solopreneur 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.
ERPNext is included in every SolOPENpreneur plan – fully managed and integrated.
