Developer teams use Confluence differently than marketing or HR. You document APIs, share architecture diagrams, write runbooks, and collaborate on code reviews. The default Confluence editor works, but it wasn't built for technical documentation.

This guide covers the best Confluence apps for developers in 2026, organized by use case. We built several of these apps at NGPILOT, so we'll be transparent about where our apps fit and where competitors offer better solutions.

Confluence uses a system font stack that looks different on every operating system. You can't change the default font globally, and Confluence offers no built-in way to use custom fonts on individual pages. This guide shows what font Confluence uses and how to add custom fonts.

Need diagram tools for Confluence without paying for a large team? NGPILOT's three diagramming apps — Mermaid Plus, Excalidraw Plus, and Graphviz Charts — are all free for up to 10 users. This guide compares them so you can pick the right free diagram plugin for your Confluence.

Displaying JSON data in Confluence pages is painful with the native code block macro — raw JSON is hard to read, especially large API responses or configuration files. JSON Structure Viewer for Confluence transforms raw JSON into an interactive visual tree that you can explore, zoom, and rotate.

Confluence is great for documentation, but it lacks built-in tools for Q&A sections. If you need FAQ pages, knowledge bases, or community-style Q&A in Confluence, NGPILOT offers two purpose-built apps.

Many teams have documentation in Markdown format (GitHub READMEs, API docs, developer guides) and need to bring it into Confluence. Confluence doesn't have a native Markdown import feature, but there are three ways to get Markdown content into Confluence pages.

Confluence's built-in code block macro is limited — it supports roughly 30 languages, has no dark theme, and lacks basic features like copy buttons and collapsible sections. If your team writes documentation with code snippets, you need something better.

This guide shows how to add a VS Code-grade code editor to Confluence with syntax highlighting for 85+ languages, automatic dark/light theme detection, and one-click copy buttons.

Adding diagrams to Confluence pages helps teams communicate architecture, processes, and workflows visually. This guide covers the three main approaches to creating diagrams in Confluence and helps you choose the right tool for your needs.

Confluence has a visual table editor, but it's slow for creating structured tables — you need to click to add rows and columns one at a time. If you write documentation in Markdown, you can create tables much faster with Markdown syntax.

This guide shows how to create, format, and edit tables in Confluence using Markdown.

No, Confluence does not support Mermaid diagrams natively. There is no built-in macro or feature that renders Mermaid syntax in Confluence pages. To add Mermaid diagrams to Confluence, you need a Marketplace app.

This guide covers how to set up Mermaid in Confluence and which diagram types you can create.
