Mercurial (hg) is a distributed version control system with full support for branching and merging. Includes commit alerts, a code browser with full syntax highlighting, and "view as a webpage".

A simple form for team members to report on "what I did", "what I will do", and "needs and obstacles". StandUp reports eliminate the needs for conference calls, speed up daily scrum chats, and help team members focus on the most important tasks.

Communicate with team members while keeping a centralized record of all conversations. Post messages from inside Assembla or by email, reply to threads, attach files, and customize email notifications.

A simple wiki to document features, ideas, specifications, or anything else. Edit pages with a WYSIWYG editor or with Textile. Restore pages to previous states using page history and rollback.

Create and organize tickets for managing development tasks, bug reports, issues, feature requests, and agile story and release planning. Includes three views - Ticket List, Cardwall, and Agile Planner.

Organize important events in your development timeline such as releases, sprints, and iterations. Milestones are required for the Tickets tool and will be installed automatically with the Ticket tool.

Add files or Google Docs with descriptions and tags. All files uploaded to tickets, messages, wiki pages, and chat are searchable in the Files tool, and all attached Google Docs are automatically "shared" with all team members.
