Best Documentation Tools in 2024
Pick the right tool to keep your docs organized and up-to-date.
Let's be honest — documentation is no one's favorite task. Most do it sloppily just to cross it off their to-do list, while others neglect to document their work altogether. A common misconception about agile documentation is that writing docs is not only tedious, it's also a waste of time.
Author and expert on the psychology of programming Gerald Weinberg summed the general attitude towards documentation by calling it "the castor oil of programming" – in other words, managers think it's good for programmers, and programmers tend to hate it.
But documentation doesn't have to be such a pain. One of the first steps towards making it less frustrating is finding the right documentation tool.
What is documentation?
Documentation refers to any material that explains how something works or how to use it. This could be in the form of manuals, guides, or even simple notes. In the context of software, docs provide essential information for both users and developers.
For users, software documentation includes guides, tutorials, and help files that explain how to install, operate, and troubleshoot software.
For developers, it offers detailed references like API documentation, code comments, and system design documents, which are crucial for understanding the internal workings and integration points of the software.
Software documentation comes in many forms, such as:
User guides. These are detailed instructions that help end-users navigate and utilize software applications. These guides often include step-by-step procedures, screenshots, and troubleshooting tips.
API docs. These are comprehensive manuals that describe how to use APIs. They typically include endpoint descriptions, parameter details, example requests and responses, and authentication methods.
Developer guides. These are technical documents aimed at developers, explaining the architecture, design patterns, and implementation details of software. These guides might include code snippets, best practices, and integration instructions.
Installation manuals. These include instructions on how to install and configure software, often including prerequisites, system requirements, and configuration steps.
Release notes. These are the documents that provide information about new features, bug fixes, and enhancements in software updates. Release notes keep users and developers informed about what has changed in a new version of the software.
Top 10 best documentation tools
If you have to deal with a clunky and slow editor, unreliable search, and an unintuitive interface every time you have to write or update a document, it's no surprise that documentation will be a source of endless frustration.
But a good documentation system can go a long way towards changing your attitude towards writing the docs. To make your decision easier, we have evaluated dozens of online documentation tools and put together a list of the 10 best picks.
1. Nuclino
Nuclino is a unified workspace where teams can organize all their knowledge, docs, and projects — like a collective brain. It's a great solution for lightweight technical documentation, but it's not all it can do.
Nuclino offers a variety of ways to structure and visualize your documents, including a nested list, a Kanban board, a table, and a mindmap-style graph, allowing you to collaborate on projects, plan your sprints, communicate asynchronously, and more. You can essentially consolidate all your work in one tool, minimizing unnecessary context-switching.
You can also turn any Nuclino workspace into a public website, accessible to anyone on the web and discoverable via search engines. It's perfect for help centers, user documentation, changelogs, and much more.
Nuclino is designed to eliminate as much friction from the writing process as possible. Its clean, intuitive interface makes it a great solution for both, technical and non-technical users. The editor supports a set of Markdown commands that allow you to quickly format your docs without taking your hands off the keyboard. Organizing your documentation is just as easy with wiki-style internal links, which allow you to link related documents together.
Every Nuclino page can be collaboratively edited in real time without edit-save-conflict cycles, and every edit is preserved in the version history. The instant search function allows you to locate the docs you need in seconds.
Nuclino also offers built-in visual collaboration and allows you to add an infinite collaborative canvas to any document. You can use it to create diagrams and flowcharts, run visual retrospectives, brainstorm ideas using sticky notes, and much more.
If you want to create clean, consistent documentation and value ease of use and speed, look no further than Nuclino.
What users say about Nuclino:
"I had never used a product like Nuclino until joining my current startup, and I've been really impressed with it. It's super easy to use and edit and it looks clean. It's been an essential tool for me as I've built out all of the documentation for my department. Some of my favorite features are the ability to pin articles and the ability to include boxes of code (and you can specify the language - there are a bunch to choose from, although I've only used SQL)."
2. Document360
Document360 is a hybrid solution that can bring together your internal and customer-facing documentation.
Notable features of Document360 include built-in localization mechanisms, content review reminders, SEO features, comments, and more. Granular analytics allow you to track how the readers interact with your docs.
Despite its extensive feature set, it's a relatively easy-to-use tool. Documentation writers can choose between a Markdown editor and visual WYSIWYG tools, tailoring the editing experience according to their preference.
Note that Document360 is less affordable than other tools on this list. Its cheapest plan starts from $99 per month and only includes customer-facing documentation features. To be able to manage both your external and internal docs in Document360, you will need to pick one of the premium plans ranging from $299 to $599 per month. While this tool may be prohibitively expensive for smaller teams, large enterprises may find that its substantial feature set is more than worth the hefty price tag.

It comes with a certain learning curve, but if you are looking for a documentation tool with advanced customization options and enterprise-level features, Confluence is definitely an option worth considering.

4. BookStack
BookStack is another wiki-style documentation tool for developers. It's open-source, self-hosted, and highly flexible.
While the interface and navigation are fairly user-friendly, note that the initial installation may require some patience and technical skills. Once your documentation platform is up and running, however, it should be easy to bring your team on board.
If you would prefer a self-hosted documentation system rather than a cloud-based one, BookStack is definitely worth evaluating.

What users say about BookStack:
"The stock interface design has a modern feel and is simple for new users to use. Granular permissions can be set up for specific roles on a per-content basis and permissions will waterfall down to child content. However, the current installation process involves many steps and may be a lot to take in for people not familiar with setting up Laravel applications."

Writing documentation in Markdown is way easier and GitBook makes it easy to organize the content. There are no cons as such, but there were a few issues while getting started, while importing the existing documentation for the first time."
