Gratis, libre and open source server providing code assistance for PHP

Serenata is a gratis, libre and open source language server that provides code assistance for PHP. Combine it with any editor supporting language servers to get access to more advanced features when writing PHP code.

What is it exactly?

Serenata is the standalone server, written in and for PHP that can be combined with editors supporting the language server protocol.

To clear up any confusion above: Serenata itself has no direct relationship to the Atom editor. The php-ide-serenata package for Atom is a so-called "client" in the form of an Atom package that integrates the server into the Atom editor. A similar client can be written for any editor.

Awesome! What do I need?


   PHP on the host

  1. Install PHP 7.1 or higher
  2. In php.ini, enable the mbstring, xml, libxml, dom, openssl and pdo_sqlite (with SQLite >= 3.7.11) extensions
  3. Open up Atom, install php-ide-serenata and follow the steps


  1. Ensure Docker is running
  2. Open up Atom, install php-ide-serenata and follow the steps

Visual Studio Code / Code OSS / VSCodium

No published plugin is available yet, but there is a working prototype available that is looking for someone that wants to develop it further and publish it on the marketplace for public consumption.

Other editors

If your editor already supports the language server protocol, integration should be straightforward. Some successes have already been reported with Sublime Text 3 as well as a proprietary editor.

Feel free to drop by with questions if you're looking to integrate it into another editor!

Where can I get more information?

You can also take a look at our wiki.

Where is the code?

The server can be found on GitLab and the Atom client package on GitHub.

Can I support you?

Serenata already sports a few advanced features, such as PhpStorm meta file support and provides a suitable solution for users looking for a free, gratis as well as libre, competitor to existing alternatives. I believe it can become the de facto free and competitive language server for PHP with the support of the community.

At the time of writing I'm the sole maintainer of this large project and work exclusively in my spare time to achieve this goal, so any donation is viewed as an appreciation of my work and a motivator to continue my efforts.
