Open-source Basecamp alternatives

Huly is an open-source platform meant to replace several tools at once, including Linear, Jira, Slack, Notion and Motion. Under the hood the Huly Platform is a framework for developing business applications such as CRM systems, and this repository includes applications for chat, project management, CRM, HR management and applicant tracking, with team and issue management covered too.

There are two important notices. First, the repository is frozen and no longer actively maintained, with development continuing in the Platform-Collective/platform repository. Second, the managed Huly service was shut down since nobody is funding its hosting any more. The remaining option is to self-host Huly or use another hosted provider, and the README points to a backup and restore guide and a community for migration help.

The code is written in TypeScript and licensed under EPL-2.0. Other teams have built products on top of the platform. Anyone interested in Huly today should look at the successor repository for current source code, issues and releases rather than relying on this one.

OpenProject is a web-based project management application for teams and organizations that value transparency, flexibility and control over their data. It covers projects, portfolios, products, tasks, bugs, agile workflows, roadmaps and team collaboration in one platform, and it is built with Ruby and Angular under the GPL-3.0 license.

Key capabilities include agile boards with Kanban and Scrum, project planning and scheduling with Gantt charts, product and release planning, bug tracking, and time tracking with cost reporting and budgeting. Collaboration tools cover wikis, forums, news, and meeting agendas and minutes. Integrations are listed for Nextcloud, XWiki, GitHub and GitLab, among others.

The project presents itself as an open-source alternative to Jira and Asana, along with tools such as MS Project, Monday and YouTrack. It can be self-hosted, which suits organizations with data sovereignty requirements. A free Community Edition is available to download, a 14-day free trial exists, and an Enterprise Edition adds support and add-ons in the cloud or on-premises.

Leantime is an open-source project management system designed for teams where most members are not trained project managers. It joins strategy, planning and execution in one tool and is built with neurodivergent users in mind, including people with ADHD, dyslexia and autism. The README pitches it as simple like Trello yet as capable as Jira.

Task management covers kanban boards, Gantt, table, list and calendar views, unlimited subtasks and dependencies, milestones, sprints and timesheets. Planning and strategy tools include goal and metrics tracking, idea boards, retrospectives, lean and business model canvases, SWOT and risk analysis. There are also wikis and documents, project dashboards, comments on everything, two-factor authentication, LDAP and OIDC, S3 or local file storage, plugins and an API, in over 20 languages.

Leantime is written in PHP, licensed under AGPL-3.0 and installs on your own server, with all of the listed features included in the open-source version. It is positioned as an alternative to Asana, ClickUp, Monday and Notion-style tools, and integrates with Slack, Mattermost and Discord. A hosted option is available at leantime.io.

Redmine is a configurable project management web application that you can host yourself. It is written with the Ruby on Rails framework, is cross-platform and cross-database, and can be configured to fit different ways of working. This repository is a GitHub mirror of the official Subversion repository.

The project site lists the main features: support for multiple projects, flexible role-based access control, an issue tracking system, a Gantt chart and calendar, news, documents and file management, feeds and email notifications, a wiki and forums for each project, and time tracking. Custom fields can be added to issues, time entries, projects and users. Integration covers Subversion, Git, Mercurial, Bazaar and CVS, issues can be created by email, and LDAP authentication, user self-registration and multiple languages and databases are supported.

Redmine is open source software distributed under version 2 of the GNU General Public License. Plugins and themes extend it, and a user's guide, developer's guide, FAQ and online demo are available on the project site.

Vikunja is a task manager that you can host and control yourself. It covers to-do lists and broader project management, and exposes an API so it can be connected to other tools. Its backend is written in Go and the web front end in Vue. The tagline stresses ownership: a task manager whose data and hosting you decide.

The README mentions an optional hosted version for people who want a hassle-free setup for themselves or a team, and a Vikunja Pro tier that adds an admin panel, audit logs and time tracking. The maintainers also note that they use LLM-assisted coding tools in parts of the codebase. The repository has documentation, a roadmap and contribution guidelines.

Vikunja is licensed under AGPL-3.0. The community version is free to self-host, which suits individuals, families and small teams who want an open alternative to hosted to-do and project apps. Support comes from donations, sponsorship and paid hosting or Pro plans.

DooTask is an open-source project and task management tool for teams. The project description lists task distribution and project management alongside online document collaboration, online mind maps, online flowcharts, instant messaging and file management, so teams can plan work and talk about it in one place. Messages use asymmetric encryption for added privacy.

Installation is done with Docker: the README requires Docker 20.10 or newer and Docker Compose v2, on Linux or Unix-like systems such as CentOS, Debian, Ubuntu and macOS, or on Windows via WSL2. It recommends at least two CPU cores and 4 GB of memory, and uses MariaDB provided by the default Compose setup. A one-line install script can set up or upgrade an installation, and a demo site and QQ group are linked.

DooTask is written in PHP and licensed under AGPL-3.0. It is designed to be self-hosted and suits small and mid-sized teams, especially Chinese-speaking ones, who want an all-in-one workspace on their own servers.

Worklenz is a project management application intended to help organizations plan work, track progress, and collaborate in one place. Teams can create projects, break them into tasks with due dates and priorities, assign people, and follow status through reports. The code is released under the AGPL-3.0 license.

Beyond task tracking, it offers time tracking on tasks and projects for resource allocation and billing, resource management, project templates, file sharing and comments for collaboration, and reports on project status, team workload, and performance. Analytics and an integration with MinIO for file storage are also part of the repository.

The frontend is built with React and Ant Design, and the backend uses TypeScript, Express.js, and PostgreSQL. You need Node.js 18 or newer and PostgreSQL 15 or newer, or you can use the Docker Compose quick start. It suits agencies and small to mid-sized teams who want a project and time-tracking tool they can run on their own servers.

Operately is an open source company operating system that helps coordinate goals, projects and teams without needing a COO. Unlike flexible tools such as Notion or ClickUp, it is opinionated: it provides the structure and proven workflows a growing company needs, from goal reviews and project check-ins to accountability routines.

Features include goals and OKRs linked to daily work, project management with task boards, milestones and consistent check-ins, team spaces for departments, message boards to replace scattered email threads, documents and files, team management with permissions, and an execution cadence of built-in check-ins and automated progress updates. A CLI and API give full programmatic access so AI agents can create goals, update projects and post check-ins, and published agent skills exist for Codex, Claude Code and other tools.

Operately is written in Elixir with a React and TypeScript front end, with a community on Discord. Its license is listed as Other, so review the repository terms before use.

Teamlinker is a team collaboration platform that brings several tools into one place so companies do not need separate apps for project progress, colleague communication and client meetings. It is built on TeamOS, a web operating system in which users can run tasks in parallel in windows, similar to a desktop operating system.

It has six functional modules: project management, wiki, calendar, meetings, chat and a network disk. The web OS offers desktop management, multiple windows, multitasking, file drag and drop, upload and download. Meetings use WebRTC for multi-person video and voice, member invitations, screen sharing, virtual backgrounds, video blur, administrator controls and in-meeting chat. A custom block editor powers the wiki.

The stack is TypeScript throughout, with Node.js on the back end and Vue 3 on the front end, and mediasoup is listed among its topics. Related open-source components include TLCalendar, TLEditor, TLMeetingClient and TLMeetingServer. Teamlinker is licensed under GPL-3.0 and has documentation in English and Chinese.
