Stage file proxy - Stage File Proxy saves you time and disk space by sending requests to your development environment's files directory to the production environment and making a copy of the production file in your development site. You should not need to enable this module in production.
Diff - This module adds a tab for sufficiently permissioned users. The tab shows all revisions like standard Drupal but it also allows pretty viewing of all added/changed/deleted words between revisions.
Environment Indicator - This module will help you to keep sane while working on your different environments by adding a configurable color bar to each one of your environments.

Site building

Address Field - Address Field defines a new field type to store international postal addresses, implementing a subset of the top-level address elements defined in the xNAL standard (see the glossary below).
Administration Views - Replaces administrative overview/listing pages with actual views for superior usability.
Views Bulk Operations (VBO) - This module augments Views by allowing bulk operations to be executed on the displayed rows. It does so by showing a checkbox in front of each node, and adding a select box containing operations that can be applied. Drupal Core or Rules actions can be used.
Date - This package contains both a flexible date/time field type Date field and a Date API that other modules can use.
Email Field - This module provides a field type for email addresses.
Entity Reference - Provides a field type that can reference arbitrary entities.
Relation - Relation is an API module and storage model for both simple and the most complex relations between entities. The module can handle both directional and symmetrical relations very well.
Field collection - A field collection is internally represented as an entity, which is embedded in the host entity. Thus, if desired field collections may be viewed and edited separately too.
Field Group - Fieldgroup will, as the name implies, group fields together. All fieldable entities will have the possibility to add groups to wrap their fields together. Fieldgroup comes with default HTML wrappers like vertical tabs, horizontal tabs, accordions, fieldsets or div wrappers.
File Field Sources - FileField Sources is an extension to the FileField module. The FileField module lets you upload files from your computer through a CCK field.
Image Link Formatter - This module is the result of the discussions around a requested feature to allow an image field to be displayed with a link to a custom URL.
Link - Allows you to add ‘link’ fields to content and has Views integration.
Media - The Media module provides an extensible framework for managing files and multimedia assets, regardless of whether they are hosted on your own site or a 3rd party site - it is commonly referred to as a 'file browser to the internet'.
Menu block - It provides configurable blocks of menu trees starting with any level of any menu.
Module Filter - The modules list page can become quite big when dealing with a fairly large site or even just a dev site meant for testing new and various modules being considered.
Panels - The Panels module allows a site administrator to create customized layouts for multiple uses. At its core it is a drag and drop content manager that lets you visually design a layout and place content within that layout. Integration with other systems allows you to create nodes that use this, landing pages that use this, and even override system pages such as taxonomy and the node page so that you can customize the layout of your site with very fine grained permissions.
Panelizer - The panelizer module allows you to attach panels to any node in the system. It is similar to the panels_node module that ships with Panels, which provides a single node type that is a panel. Panelizer, however, allows this to work for many entity types. It works by using the Page Manager template to take over the page rendering of the node.
Pathauto - The Pathauto module automatically generates URL/path aliases for various kinds of content (nodes, taxonomy terms, users) without requiring the user to manually specify the path alias. This allows you to have URL aliases like /category/my-node-title instead of /node/123. The aliases are based upon a "pattern" system that uses tokens which the administrator can change.
Rules - The Rules module allows site administrators to define conditionally executed actions based on occurring events (known as reactive or ECA rules). It's a replacement with more features for the trigger module in core and the successor of the Drupal 5 workflow-ng module.
Search API - This module provides a framework for easily creating searches on any entity known to Drupal, using any kind of search engine. For site administrators, it is a great alternative to other search solutions, since it already incorporates facetting support and the ability to use the Views module for displaying search results, filters, etc. Also, with the Apache Solr integration, a high-performance search engine is available for this module.
Smart Trim - Smart Trim implements a new field formatter for textfields (text, text_long, and text_with_summary, if you want to get technical) that improves upon the "Summary or Trimmed" formatter built into Drupal 7.
Views - This is the reason why you are using Drupal. Views in now in Drupal 8 core.
Views RSS - This module allows users to take control of their feeds by providing a fields-based views style plugin for RSS.
Entityform - The Entityform module enables you to create front-end forms (fieldable entities), which contain fields that you define! These forms use the standard Drupal fields.
Webform - Webform is the module for making surveys in Drupal. After a submission, users may be sent an e-mail "receipt" as well as sending a notification to administrators. Results can be exported into Excel or other spreadsheet applications. Webform also provides some basic statistical review and has and extensive API for expanding its features.

Content

Feeds + Feeds Tamper + Feeds Xpath Parser - Import or aggregate data as nodes, users, taxonomy terms or simple database records.
Flag - Flag is a flexible flagging system that is completely customizable by the administrator. Using this module, the site administrator can provide any number of flags for nodes, comments, users, and any other type of entity. Some possibilities include bookmarks, marking important, friends, or flag as offensive.

Publishing

Nodequeue - The Nodequeue module allows users to collect nodes in an arbitrarily ordered list.
Entityqueue - The Entityqueue module allows users to create queues of any entity type. Each queue is implemented as an Entityreference field, that can hold a single entity type.
Linkit - Linkit provides an easy interface for internal and external linking with editors and fields by using an autocomplete field. Linkit links to nodes, users, managed files, terms and have basic support for all entities by default.
Wysiwyg - Allows the use of client-side editors to edit content. It simplifies the installation and integration of the editor of your choice. This module replaces all other editor integration modules. No other Drupal module is required.

SEO

Global Redirect - A helpful SEO-based module that helps Drupal not appear to have duplicate URLs so that your site isn’t penalized by search engines.
Google Analytics - Adds the Google Analytics web statistics tracking system to your website.
Metatag - The Metatag module allows you to automatically provide structured metadata, aka "meta tags", about a website. In the context of search engine optimization, when people refer to meta tags they are usually referring to the meta description tag and the meta keywords tag that may help improve the rankings and display of a site in search engine results. In addition, the module provides support for meta tags (Open Graph Protocol from Facebook, Twitter Cards from Twitter) that allow control of how content appears when shared on social networks.
Redirect - This module is critical for providing 301 redirects on your site.
XML Site Map - The XML sitemap module creates a sitemap that conforms to the sitemaps.org specification. This helps search engines to more intelligently crawl a website and keep their results up to date. The sitemap created by the module can be automatically submitted to Ask, Google, Bing (formerly Windows Live Search), and Yahoo! search engines. The module also comes with several submodules that can add sitemap links for content, menu items, taxonomy terms, and user profiles.
Page Title - This module is deprecated, all functionality is being moved into the Metatag module, an upgrade process is available and is being improved.

This module is built with simplicity and flexibility in mind, it provides login services (and does it well), and an API for performing any other actions you may want to write yourself to query against Facebook's APIs.
Twitter Block - Twitter Block is a lightweight module which allows administrators to create blocks which display embedded timelines.
Twitter - This module provides API integration with the Twitter microblogging service. Out of the box, it allows users to: Associate one or more Twitter accounts with their Drupal user account. List tweets in different ways thanks to Views. Post to their own Twitter account or a site-wide Twitter account whenever they create new content or based on Drupal Actions or Rules. Log in to your Drupal site via Twitter. Format twitter @usernames and #hashtags as links to Twitter.com. Search and post to Twitter via Drush commands.

Utility / API Modules

Chaos tool suite (ctools) - This suite is primarily a set of APIs and tools to improve the developer experience. It also contains a module called the Page Manager whose job is to manage pages. In particular it manages panel pages, but as it grows it will be able to manage far more than just Panels.
Entity API - This module extends the entity API of Drupal core in order to provide a unified way to deal with entities and their properties. Additionally, it provides an entity CRUD controller, which helps simplifying the creation of new entity types.
Entity cache - Entity cache puts core entities into Drupal's cache API.
File entity (fieldable files) - File entity provides interfaces for managing files. It also extends the core file entity, allowing files to be fieldable, grouped into types, viewed (using display modes) and formatted using field formatters.
