+Nodejitsu's database offering allows you to easily create a free tier database
+with our database partners.
+
+### [MongoDB](/documentation/databases/mongodb)
+
+[MongoDB][mongodb] is an open source document database created by 10gen. MongoDB
+is really popular for Node.js applications as it's build on top of JavaScript
+and using JSON in Node feels really natural. It features:
+
+<dl>
+  <dt>Document Oriented</dt>
+  <dd>It stores JSON documents with flexible schema's</dd>
+
+  <dt>Querying</dt>
+  <dd>Custom query language that is optimized for JSON documents</dd>
+
+  <dt>In-place updates<dt>
+  <dd>Atomic modifiers for contention-free performance</dd>
+
+  <dt>Map/Reduce</dt>
+  <dd>Map/Reduce can be used for data aggregation and processing</dd>
+
+  <dt>GridFS</dt>
+  <dd>Supports storing files of any size without complicating your stack</dd>
+</dl>
+
+### [Redis](/documentation/databases/redis)
+
+[Redis][redis] is an open source key-value database created by antirez. It's
+famous for it's high speed which achieved by storing all data in memory. It has
+uses a simple protocol that was inspired by the memcached ASCII protocol. Some
+of it's highlights:
+
+<dl>
+  <dt>Different data types</dt>
+  <dd>Add data to lists, hashes or sets.</dd>
+
+  <dt>Pub/Sub</dt>
+  <dd>Redis comes with fast and stable Publish/Subscribe messaging system build in</dd>
+
+  <dt>Lua scripting</dt>
+  <dd>Execute Lua scripts to aggregate and process data</dd>
+
+  <dt>Expires</dt>
+  <dd>Redis allows you to set the time to live different for every key</dd>
+</dl>
+
+### [CouchDB](/documentation/databases/redis)
+
+[Couchdb][couchdb] is also an open source database that uses JSON for
+documentation storage, JavaScript for Map/Reduce queries and HTTP for an API. As
+HTTP is a first class citizen in Node.js it's really easy to use this. But also:
+
+<dl>
+  <dt>Build for Offline</dt>
+  <dd>
+    CouchDB can replicate to devices (like smartphones) that go offline and
+    syc when it's online
+  </dd>
+
+  <dt>ACID</dt>
+  <dd>It does this by implementing Multi-Version Concurrency Control</dd>
+</dl>
+
+## Do we get access to the providers web interfaces?
+
+The database details that are created for database do no provide you with access
+to the providers web interfaces. The databases are created Nodejitu's account
+and thus not accessible.
