UnQLite is a in-process software library which implements a self-contained, serverless, zero-configuration, transactional NoSQL database engine.It is a document store database similar to MongoDB, Redis, CouchDB, etc. as well a standard key/value store similar to BerkeleyDB, LevelDB, etc. It reads and writes directly to ordinary disk files. A complete database with multiple collections is contained in a single disk file. The database file format is cross-platform, and you can freely copy a database between 32-bit and 64-bit systems or between big-endian and little-endian architectures.

hulk is a usable in-browser HTML editor. Running $.hulk with some options will insert a pretty JSON editor into the div with the id "selector". You can then edit the document at your leisure, in text input boxes instead of as JSON. This makes it easy for programmers and non-technical people to collaborate on configuration. Hulk is also smart about detecting your input (if it's large, use a textarea, if it looks like a number, convert it to a number, etc.).
