Bluefish vs IntelliJ IDEA

Bluefish is a free, open-source desktop editor for programmers and web developers writing websites, scripts and programming code. It runs on Linux, macOS and Windows and supports more than 30 markup and programming languages. The multi-document interface can open 1,000 or more documents, with more than 10,000 tested simultaneously. Editing tools include regular-expression search and replace, code folding, auto-completion and automatic tag closing. Project support restores settings for each project. Through gvfs, Bluefish works with remote files over FTP, SFTP, HTTP, HTTPS, WebDAV, CIFS and other protocols. Users can connect external programs such as make, lint, weblint, xmllint, tidy and javac, or run custom programs and scripts. The Flatpak build has strict security restrictions that block integration with some system tools and the web browser, although internal functionality works. Community support is volunteer-run through a mailing list and bug tracker. Bluefish is released under the GNU GPL license.

IntelliJ IDEA is an IDE for professional Java and Kotlin development, available on Windows, macOS, and Linux. It offers context-aware completion, static analysis, and automated refactoring. The JVM debugger includes breakpoints, variable inspection, expression evaluation, and step-by-step execution. Gradle and Maven integrations cover building, packaging, testing, and deployment, while version-control support includes Git, Mercurial, Perforce, and Subversion. Users can process GitHub pull requests in the IDE, and plugins from JetBrains Marketplace add support for other languages, frameworks, and technologies. Core Java and Kotlin functionality remains free after the included 30-day Ultimate trial ends. The Ultimate subscription adds advanced tools and integrations and costs $100.00 for the first year, $199.00 for the second year, and $159.00 per year from the third year onward. Listed minimum hardware is a 4-core x86_64 or arm64 CPU, 8 GB total RAM, and 10 GB of disk space. Users can choose in IDE settings whether to share anonymous usage data.
