Huly: Open-Source Platform to Replace Notion, Slack, and Linear
Huly is a self-hosted, open-source platform that brings project management, documentation, team chat, and GitHub integration together in one unified workspace. If you find yourself moving between separate tools for specs, issues, conversations, and code, you have likely felt the productivity cost of that fragmentation. Every extra app switch interrupts focus and adds friction to your development process.
In this guide, you’ll explore how Huly addresses that problem. You’ll deploy your own instance with Docker in just a few steps and walk through its key features, including project tracking, seamless GitHub synchronization, collaborative docs, and built-in communication. By the end, you’ll know exactly what Huly can do and whether it belongs at the center of your workflow.
The problem with a fragmented workflow
Before diving into the solution, fully appreciating the problem is crucial. The modern software development toolkit is a patchwork of specialized applications. While specialization can be powerful, it introduces inherent inefficiencies that can slow down even the most agile teams.
The high cost of context switching
The primary issue is context switching. Consider a typical workflow for fixing a bug: a user reports a bug in a Slack channel, a developer copies the report and creates a formal issue in a project management tool like Linear, the developer consults the original feature specification in a Notion document to understand the intended behavior, they switch to their IDE and GitHub to create a new branch and start working on the code, once the fix is ready they create a Pull Request on GitHub, they then go back to Linear to link the PR to the issue and move the ticket to the "In Review" column, and finally they post an update in the original Slack channel to notify the team.
In this simple scenario, the developer has switched between at least four different applications. Each switch, no matter how brief, breaks concentration and introduces a mental "re-tooling" cost. Information is scattered, and the risk of miscommunication or losing track of details increases with every new platform added to the mix. These small interruptions add up, leading to days where we feel incredibly busy but have little to show for it in terms of shipped code.
The burden of multiple subscriptions
The second major pain point is financial. The Software-as-a-Service (SaaS) model, with its per-seat pricing, means that costs scale directly with the size of your team. A subscription of $10 per user per month might seem negligible for a solo developer, but for a team of 20, that's $200 per month for just one tool. When you multiply this across four or five essential applications, the total monthly cost can easily run into the thousands of dollars. This financial burden can be particularly challenging for startups, small businesses, and open-source projects operating on tight budgets.
The limitations of self-hosted alternatives
In an attempt to mitigate these issues, many teams turn to open-source, self-hosted alternatives. However, this path often comes with its own set of compromises. Many self-hosted tools are either clunky, lack the polished user experience of their SaaS counterparts, or are missing critical features that teams rely on. You might find a great open-source project tracker, but it won't have integrated chat. You might find a self-hosted wiki, but its code block support is rudimentary. This often leads teams back to the fragmented workflow they were trying to escape, just with a different set of tools.
This is the landscape into which Huly enters, offering a solution that is not only self-hosted and open-source but also comprehensive and designed with the developer experience at its core.
Introducing Huly: the everything app for your team
Huly is an open-source, all-in-one collaboration platform that integrates the essential functions of modern development workflows into a single application. It's not just a collection of features glued together; it's a thoughtfully designed ecosystem where every component is aware of and connected to the others.
The platform provides a suite of powerful tools that directly replace the need for separate services: project management (a fast, Kanban-style issue tracker that feels as snappy and intuitive as Linear), real-time documentation (a collaborative document editor, similar to Notion, with first-class support for code blocks and syntax highlighting), built-in chat (a real-time messaging system that functions like Slack, with channels, direct messages, and threads), inbox and calendars (a unified inbox to track all your notifications and tasks, along with integrated team calendars), and seamless GitHub sync (a deep, bi-directional integration with GitHub that keeps your issues and codebase perfectly in sync).
Because Huly is self-hosted, you retain complete control over your data and infrastructure. There are no per-seat costs, and you can customize and extend the platform to fit your team's specific needs. It aims to combine the speed of Linear, the flexibility of Notion, the communication power of Slack, and the essential integration with GitHub into one cohesive, developer-centric package.
Getting started: self-hosting Huly with Docker
One of the most impressive aspects of Huly is how simple it is to get a self-hosted instance up and running. Thanks to a well-crafted setup script and the power of Docker, you can go from zero to a fully functional platform in just a few minutes.
Prerequisites
Before beginning, you'll need to have two things installed on your local machine or server: Git (for cloning the Huly repository) and Docker and Docker Compose (for running the Huly application containers). This tutorial will demonstrate the setup on a local machine, but the steps are identical for a Virtual Private Server (VPS), which would be the recommended approach for a production team environment.
Installation steps
Follow these steps to deploy your Huly instance.
First, open your terminal and navigate to the directory where you want to install Huly. Then, run the following git clone command to download the necessary configuration files from the official repository:
This command will create a new directory named huly-selfhost. Next, change your current directory to the newly created folder:
All subsequent commands will be run from within this directory. The Huly team has provided a convenient setup script that automates the entire installation process. To run it in quick mode, which uses sensible defaults for a fast setup, execute:
This script will perform several actions: it checks for the necessary dependencies (like Docker), generates the required configuration files, pulls all the necessary Docker images for the various Huly services (database, frontend, backend, etc.), and starts all the services using docker compose. You will see a flurry of activity in your terminal as Docker downloads the images and starts the containers. This process may take a few moments, depending on your internet connection speed.
Once the script completes, it will display a message indicating that the setup is complete and provide the URL to access your new Huly instance. By default, this will be http://localhost:8087. Open your web browser and navigate to this address. You will be greeted by the Huly sign-up screen, confirming that your installation was successful.
The final step is to create your administrator account and your first workspace. On the sign-up page, fill in your name, email, and a secure password. Click "Sign Up". You will then be prompted to create a workspace. Give your workspace a name (e.g., "My Dev Team") and click "Create workspace".
That's it! You are now logged into your brand new, self-hosted Huly platform. The entire process, from cloning the repository to logging in, takes less than 90 seconds.
A guided tour of the Huly workspace
With the instance up and running, exploring the core features of Huly reveals how they come together to create a unified development workflow.
Project management: creating projects and issues
The heart of any development workflow is project and task management. Huly's "Tracker" module provides a clean, fast, and feature-rich environment for this.
When you first land in the workspace, you can create a new project. The creation dialog allows you to configure essential details: project title (a human-readable name for your project), identifier (a short, unique key for your project's issues, e.g., TSK), and assignees and owners (you can set default assignees for new issues and define who owns the project).
Once the project is created, you are presented with a Kanban-style board. The interface is minimal and responsive, avoiding the lag often associated with more complex web applications. Creating a new issue is instantaneous. A modal pops up where you can add a title, description, and set properties like priority, labels, and milestones. This experience is very similar to modern tools like Linear, prioritizing speed and keyboard-driven actions to keep developers in their flow.
Seamless GitHub integration: a two-way sync
This is where Huly truly begins to shine and differentiate itself from other project management tools. It offers a deep, bi-directional synchronization with GitHub.
To set up the integration, navigate to your workspace settings, go to the "Integrations" section, find GitHub and click "Connect". You'll be guided through an OAuth flow to authorize Huly to access your GitHub account. Once authorized, you can connect specific Huly projects to specific GitHub repositories.
Once a project is connected, the magic happens. Any issue created in your GitHub repository will automatically appear as a task on your Huly project board (GitHub to Huly). You can create an issue in Huly, and it will be synced back to your GitHub repository (Huly to GitHub).
This two-way sync is a game-changer. It eliminates the duplicate work of manually creating issues in two places. Your project board in Huly becomes a true reflection of the state of your codebase's issues. When a developer creates a bug report on GitHub, it's immediately visible to the project manager in Huly without any manual intervention.
Furthermore, you can link Pull Requests directly to Huly tasks. Within a task's activity feed, you can reference a PR number. This creates a clear, auditable trail connecting the work being tracked on the project board to the actual code changes being implemented, bridging the gap between project management and software development.
Collaborative documentation: more than just notes
Effective documentation is critical for any project. Huly includes a "Documents" module that serves as a powerful, Notion-like knowledge base.
You can create documents and organize them into team spaces. The editor is real-time and collaborative, allowing multiple team members to edit a document simultaneously. But crucially, it's built for developers.
The standout feature here is its code block implementation. When you add a code block, you can specify the language (e.g., TypeScript, Python, Bash), and Huly provides proper, accurate syntax highlighting. This is a significant improvement over many other wiki tools where code blocks are often rendered as plain, unformatted text. This makes it an ideal place to write feature specifications, technical design documents, API documentation, and onboarding guides with code examples.
Even better, the documentation is integrated with the rest of the platform. From within a document, you can use the @ symbol to mention and link directly to a specific task in your project tracker. This allows you to write a spec for a new feature and link it directly to the epic or individual tasks that will implement it, ensuring that context is never lost.
Built-in communication: the Slack alternative
To complete the trifecta, Huly includes a fully-featured chat module. The interface will be immediately familiar to anyone who has used Slack or Discord.
You have channels (for team-wide or topic-specific discussions), direct messages (for one-on-one conversations), and threads (to keep conversations organized).
The chat functionality is clean and simple. However, its real power lies in its integration. When a discussion in a channel leads to an actionable item, you don't need to switch to another app. You can take any message and, with a single click, convert it directly into a task in your project tracker. This simple action solves a common pain point in Slack-based workflows, where important decisions and action items can easily get lost in the endless scroll of conversation.
Practical considerations and limitations
While Huly is an incredibly promising platform, approaching it with a realistic understanding of its current state and requirements is important.
Resource intensity: Huly is a comprehensive platform running multiple services in Docker containers. As such, it is more resource-heavy than a simple standalone application. The developers recommend a server with at least 8GB of RAM for a smooth experience, especially for teams. This means that while it's free in terms of software cost, there will be a hardware or VPS hosting cost to consider for any serious deployment.
Setup and maintenance: Although the initial setup is easy, running a self-hosted application means you are responsible for its maintenance, updates, and security. This requires a certain level of technical expertise and is more involved than simply signing up for a SaaS product.
Mobile experience: Huly does have a mobile app, but it is currently very basic. It's useful for checking notifications on the go, but it doesn't yet offer the full functionality of the desktop web application. Teams that rely heavily on mobile access may find this to be a limitation.
Maturity: Huly is still a growing project. While the core experience is solid, you may encounter occasional bugs or find that certain niche features from more mature platforms are not yet implemented.
Final thoughts
Huly gives you a streamlined development workflow without constant context switching or escalating subscription costs. By unifying project management, documentation, communication, and GitHub integration, it helps you stay focused on building instead of bouncing between tools.
Its performance, clean interface, and meaningful integrations set it apart. The two-way GitHub sync ensures your planning and code remain tightly connected, keeping issues and implementation in sync.
Self-hosting comes with responsibility, but the benefits can outweigh the overhead. If you want to consolidate your tools, own your data, and cut down on SaaS spending, Huly is a strong open-source alternative worth trying. With a setup that takes about 90 seconds, you can deploy it quickly and see if it fits your workflow.
